In summary: f(x, y) has a local maximum at DNE (since there are no points of local maximum). f(x, y) has a local minimum at DNE (since there are no points of local minimum). f(x, y) has a saddle point at (0, 0).
To find and classify the critical points of the function f(x, y) = -4xy - x³ - 2y², we need to find the points where the gradient of the function is zero or undefined.
Taking the partial derivatives with respect to x and y:
∂f/∂x = -4y - 3x²
∂f/∂y = -4x - 4y
Setting both partial derivatives to zero, we have:
-4y - 3x² = 0 ...(1)
-4x - 4y = 0 ...(2)
Solving equations (1) and (2) simultaneously, we get:
x = 0
y = 0
So, the critical point is (0, 0).
To classify the critical point, we need to determine the nature of the critical point by examining the second-order partial derivatives.
Taking the second partial derivatives:
∂²f/∂x² = -6x
∂²f/∂y² = -4
∂²f/∂x∂y = -4
Evaluating the second partial derivatives at the critical point (0, 0), we have:
∂²f/∂x² = 0
∂²f/∂y² = -4
∂²f/∂x∂y = -4
Using the second partial derivative test, we can classify the critical point:
If ∂²f/∂x² > 0 and (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² > 0, it is a local minimum.
If ∂²f/∂x² < 0 and (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² > 0, it is a local maximum.
If (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² < 0, it is a saddle point.
At the critical point (0, 0), we have:
∂²f/∂x² = 0
∂²f/∂y² = -4
∂²f/∂x∂y = -4
Since ∂²f/∂x² = 0 and (∂²f/∂x²)(∂²f/∂y²) - (∂²f/∂x∂y)² = 0 - (-4)(-4) = -16 < 0, the critical point (0, 0) is a saddle point.

If a man earns a salary of $16,008 a year and is paid semimonthly, how much is his semimonthly paycheck before taxes?
The man earns $______ semimonthly before taxes. (Round to the nearest cent as needed.)
The man's semimonthly paycheck before taxes is $667.33.
To calculate the semimonthly paycheck before taxes, we need to divide the annual salary by the number of pay periods in a year. In this case, the man earns $16,008 per year and is paid semimonthly.
There are usually 24 semimonthly pay periods in a year (twice a month for 12 months). To find the semimonthly paycheck, we divide the annual salary by 24:
$16,008 / 24 = $667.33 (rounded to the nearest cent)
Therefore, the man's semimonthly paycheck before taxes is $667.33.

Below are two sets of real numbers. Exactly one of these sets is a ring, with the usual addition and multiplication operations for real numbers. Select the one which is a ring.
{3k +1: k ∈ Z} {3k: k ∈ z) Let R be the ring above. True or false:
R is a ring with identity.
R is a skewfield. R is a commutative ring.
The set {3k + 1: k ∈ Z} is a ring with the usual addition and multiplication operations for real numbers. In the second part, we will determine the properties of this ring.
The set {3k + 1: k ∈ Z} is a ring. To verify this, we need to check if it satisfies the ring axioms. The ring axioms include closure under addition and multiplication, associativity, commutativity, the existence of an additive identity and additive inverses, and the distributive property.
Closure: For any two elements (3k + 1) and (3m + 1) in the set, their sum (3k + 1) + (3m + 1) = 3(k + m) + 2 is also in the set. Similarly, their product (3k + 1)(3m + 1) = 3(3km + k + m) + 1 is also in the set.
Associativity: Addition and multiplication are associative operations on real numbers, so they are associative in this set as well.
Commutativity: Addition and multiplication are commutative operations on real numbers, so they are commutative in this set as well.
Additive Identity: The additive identity in this set is 1, since for any element (3k + 1) in the set, (3k + 1) + 1 = 3k + 2 is still in the set.
Additive Inverses: For any element (3k + 1) in the set, its additive inverse is (-3k - 1), since (3k + 1) + (-3k - 1) = 0, which is the additive identity.
Distributive Property: The distributive property holds for addition and multiplication in this set.
Therefore, {3k + 1: k ∈ Z} is a ring with the usual addition and multiplication operations for real numbers. Regarding the second part: R is a ring with identity: True. Element 1 serves as the additive identity in this ring.
R is a skew field: False. A skew field is a non-commutative division ring, and since R is commutative, it cannot be a skew field.
R is a commutative ring: True. As mentioned earlier, addition and multiplication are commutative in this ring, satisfying the definition of a commutative ring.
In summary, {3k + 1: k ∈ Z} is a ring with the usual addition and multiplication operations for real numbers. It is a commutative ring with identity but is not a skew field.

Find the area of one petal of the rose curve given by r = 3 sin 20 ? b)-example 5- Find the area of the region enclosed by the inner loop of the limacon r=1-2 cos 0
(a) To find the area of one petal of the rose curve given by r = 3sin(20θ), we can use the formula for the area of a polar region, which is given by A = (1/2)∫[θ₁,θ₂] r² dθ.
In this case, since we want to find the area of one petal, we can choose the limits of integration as θ₁ = 0 and θ₂ = π/10, which corresponds to one complete petal. (b) In Example 5, we are asked to find the area of the region enclosed by the inner loop of the limaçon given by r = 1 - 2cos(θ). To calculate this area, we can again use the formula for the area of a polar region, A = (1/2)∫[θ₁,θ₂] r² dθ. In this case, we need to determine the appropriate limits of integration that enclose the inner loop of the limaçon. (a) For the rose curve given by r = 3sin(20θ), to find the area of one petal, we use the formula A = (1/2)∫[θ₁,θ₂] r² dθ. In this case, we want to calculate the area of one complete petal, so we choose the limits of integration as θ₁ = 0 and θ₂ = π/10. Substituting the given value of r into the formula, we have A = (1/2)∫[0,π/10] (3sin(20θ))² dθ. Simplifying the integrand and evaluating the integral, we can calculate the area.
(b) To find the area of the region enclosed by the inner loop of the limaçon given by r = 1 - 2cos(θ), we use the formula A = (1/2)∫[θ₁,θ₂] r² dθ. In this case, we need to determine the appropriate limits of integration that enclose the inner loop. The inner loop occurs when the value of r is negative, which corresponds to θ values between π/2 and 3π/2. Thus, we choose the limits of integration as θ₁ = π/2 and θ₂ = 3π/2. Substituting the given value of r into the formula, we have A = (1/2)∫[π/2,3π/2] (1 - 2cos(θ))² dθ. Simplifying the integrand and evaluating the integral will give us the area enclosed by the inner loop of the limaçon.
By following the steps outlined above and performing the necessary calculations, we can determine the precise values for the areas of one petal of the rose curve and the region enclosed by the inner loop of the limaçon.

Find possible dimensions for a closed box with volume 1014 cubic inches, surface area 910 square inches, and length that is twice the width. Select the correct answer below and, if necessary, fill in the answer box(es) to complete your choice. (Use a comma to separate answers as needed. Type an integer or decimal rounded to two decimal places as needed.) A. There is only one possibility. The dimensions are __ in. B. There are two possibilities. The dimensions whose width is larger are in. The dimensions whose width is smaller are __ in.
Correct option is B. There are two possibilities. The dimensions whose width is larger are approximately 19.38 inches, and the dimensions whose width is smaller are approximately 9.69 inches.
To find the possible dimensions for the closed box, we can set up a system of equations based on the given information.
Let's denote the length of the box as L, the width as W, and the height as H.
From the given conditions:
The volume of the box is 1014 cubic inches:
V = LWH = 1014
The surface area of the box is 910 square inches:
SA = 2(LW + LH + WH) = 910
The length is twice the width:
L = 2W
Using these equations, we can solve for the dimensions.
Substituting L = 2W into equations (1) and (2), we have:
(2W)(W)(H) = 1014
2(W^2)H = 1014
2(LW) + 2(LH) + 2(WH) = 910
4(W^2) + 4(WH) + 2(WH) = 910
4(W^2) + 6(WH) = 910
Simplifying equation (4):
(W^2) + 3(WH) = 455
We have two equations now:
2(W^2)H = 1014 (equation 3)
(W^2) + 3(WH) = 455 (equation 4)
By solving this system of equations, we can find the possible dimensions for the box.

Find (u, v), u, |v||, and d(u, v) for the given inner product defined on Rⁿ. u = (1, 2, 3), v = (2, 1, 3), (u, v) = u . v (a) (u, v) (b) ||u|| (c) ||v|| (d) d(u, v) For what values of a and ß will the vector (a, 1, ß) be orthogonal to (4, 0, 7) and (-1, 1, 2)?
In this task, we are given two vectors, u and v, in Rⁿ along with a specific inner product defined as the dot product between the vectors. We are asked to find several properties related to these vectors and the inner product.
Specifically, we need to determine the inner product (u, v), the norms of vectors u and v (||u|| and ||v||), and the distance between vectors u and v (d(u, v)).
To find the inner product (u, v), we simply compute the dot product of the given vectors u and v. The norm of a vector ||u|| represents its length or magnitude and can be calculated using the formula ||u|| = √(u · u), which involves taking the square root of the dot product of u with itself. Similarly, ||v|| is calculated in the same manner.
The distance between two vectors, d(u, v), can be determined using the formula d(u, v) = ||u - v||, where ||u - v|| represents the norm or length of the vector obtained by subtracting v from u.
In the second part of the task, we are asked to find the values of a and ß that make the vector (a, 1, ß) orthogonal to two given vectors, (4, 0, 7) and (-1, 1, 2). To check orthogonality, we compute the dot product of the vectors and set it equal to zero. Solving the resulting equations will provide the values of a and ß that satisfy the orthogonality condition.

The cards are taken from a standard 52-card deck.
a) Find the number of possible 5-card hands that contain 4 spades and 1 other card.
b) Find the number of possible 5-card hands that contain at most 3 aces.
a) The number of possible 5-card hands that contain 4 spades and 1 other card is 27,885. This is calculated by choosing 4 spades out of the 13 available spades (715 ways) and choosing 1 card from the remaining 39 non-spade cards (39 ways).
b) The total number of possible 5-card hands with at most 3 aces is obtained by summing up the results from all four scenarios.
a) To find the number of possible 5-card hands that contain 4 spades and 1 other card, we can break down the problem into two steps.
Step 1: Choosing 4 spades out of the 13 available spades. This can be done in C(13, 4) ways, which is the combination formula and equals 715.
Step 2: Choosing 1 card from the remaining 52 - 13 = 39 non-spade cards. This can be done in C(39, 1) = 39 ways.
To find the total number of possible 5-card hands with 4 spades and 1 other card, we multiply the results from Step 1 and Step 2:
Total = C(13, 4) * C(39, 1) = 715 * 39 = 27,885.
Therefore, there are 27,885 possible 5-card hands that contain 4 spades and 1 other card.
b) To find the number of possible 5-card hands that contain at most 3 aces, we need to consider different scenarios: hands with 0, 1, 2, or 3 aces.
Scenario 1: 0 aces
For this scenario, we need to choose 5 cards from the 52 - 4 = 48 non-ace cards. This can be done in C(48, 5) ways.
Scenario 2: 1 ace
We need to choose 1 ace from the 4 available aces and 4 non-ace cards from the remaining 52 - 4 - 1 = 47 cards. This can be done in C(4, 1) * C(47, 4) ways.
Scenario 3: 2 aces
We need to choose 2 aces from the 4 available aces and 3 non-ace cards from the remaining 52 - 4 - 2 = 46 cards. This can be done in C(4, 2) * C(46, 3) ways.
Scenario 4: 3 aces
We need to choose 3 aces from the 4 available aces and 2 non-ace cards from the remaining 52 - 4 - 3 = 45 cards. This can be done in C(4, 3) * C(45, 2) ways.
To find the total number of possible 5-card hands with at most 3 aces, we sum up the results from all four scenarios:
Total = C(48, 5) + (C(4, 1) * C(47, 4)) + (C(4, 2) * C(46, 3)) + (C(4, 3) * C(45, 2)).
By calculating each term individually and summing them up, we can find the total number of possible 5-card hands with at most 3 aces.

What are the zeros of the polynomial function x² + 5x + 6 a. x = -2, -6 b. x = 3,5 c. x = -2, -3 d. x = -1, 6 e. x = -5, 6
The zeros of the polynomial function x² + 5x + 6 can be found by solving the equation x² + 5x + 6 = 0. The correct zeros of the polynomial can be determined by factoring or using the quadratic formula.
To find the zeros of the polynomial function x² + 5x + 6, we need to solve the equation x² + 5x + 6 = 0. We can try to factor the quadratic expression or use the quadratic formula to find the roots.
Factoring method:
We are looking for two numbers that multiply to give 6 and add up to 5. By factoring, we find that (x + 2)(x + 3) = 0. Setting each factor equal to zero:
x + 2 = 0, x + 3 = 0
Solving these equations, we find the zeros:
x = -2, x = -3
Therefore, the zeros of the polynomial function x² + 5x + 6 are x = -2 and x = -3. Comparing these zeros to the given options, we can see that the correct answer is c. x = -2, -3.
Using the quadratic formula:
The quadratic formula is x = (-b ± √(b² - 4ac)) / (2a), where a, b, and c are the coefficients of the quadratic equation ax² + bx + c = 0.
For the equation x² + 5x + 6 = 0, we have a = 1, b = 5, and c = 6. Substituting these values into the quadratic formula:
x = (-5 ± √(5² - 4(1)(6))) / (2(1))
= (-5 ± √(25 - 24)) / 2
= (-5 ± √1) / 2
= (-5 ± 1) / 2
Simplifying further, we get the same zeros as before:
x₁ = (-5 + 1) / 2 = -4 / 2 = -2
x₂ = (-5 - 1) / 2 = -6 / 2 = -3
Therefore, using either factoring or the quadratic formula, we find that the zeros of the polynomial function x² + 5x + 6 are x = -2 and x = -3. The correct answer is c. x = -2, -3.

To calculate the steady-state population percentage of Taipei citizens relative to the overall Taiwanese population (excluding Taipei citizens) 100 years later, we can use a population vector and the probability transfer matrix.
Let's define the population vector:
G: u100[Taiwan, Taipei] = [P(Taiwan), P(Taipei)]
And the probability transfer matrix:
P0 = [P(Taiwan to Taiwan), P(Taiwan to Taipei)]
[P(Taipei to Taiwan), P(Taipei to Taipei)]
Given the migration rates, we have:
P(Taiwan to Taipei) = 0.1 (10% of Taiwanese moving into Taipei annually)
P(Taipei to Taiwan) = 0.08 (8% of Taipei citizens moving out to other Taiwanese cities annually)
To find the steady-state population vector after 100 years, we can use the equation:
G: u100 = P0 * u99
where u99 is the population vector at the previous year.
To calculate u100, we can start with an initial population vector:
G: u0[Taiwan, Taipei] = [1, 0]
Then, iteratively apply the equation:
G: u1 = P0 * u0
G: u2 = P0 * u1
...
G: u99 = P0 * u98
G: u100 = P0 * u99
Let's calculate the steady-state population vector for Taipei citizens relative to the overall Taiwanese population (excluding Taipei citizens) 100 years later:
P(Taiwan to Taiwan) = 1 - P(Taiwan to Taipei) = 1 - 0.1 = 0.9
P(Taipei to Taipei) = 1 - P(Taipei to Taiwan) = 1 - 0.08 = 0.92
P0 = [0.9, 0.1]
[0.08, 0.92]
u0 = [1, 0]
for (i in 1:100) {
G <- P0 %*% G
}
The steady-state population vector u100[Taiwan, Taipei] will give us the percentage of Taipei citizens relative to the overall Taiwanese population (excluding Taipei citizens) 100 years later. Please note that this calculation assumes constant migration rates and a closed population system (excluding births, deaths, and other factors).

d. Not possible.
To find the product AB of matrices A and B, we need to perform matrix multiplication. After multiplying A = [-1 2][-1 3] with B = [2 4][3 1][1 1], the resulting matrix is [-6 14][-7 12][-3 5]. The option b. [-6 14][-7 12][-3 5] is the correct answer.
To find the product AB, we perform matrix multiplication by multiplying the corresponding elements of the rows of A with the columns of B and summing the products. Let's calculate the product AB:
A = [-1 2][-1 3]
B = [2 4][3 1][1 1]
The first row of A, [-1 2], is multiplied with the first column of B, [2 3 1], as follows:
(-1 * 2) + (2 * 3) = -2 + 6 = 4
Similarly, the first row of A is multiplied with the second column of B:
(-1 * 4) + (2 * 1) = -4 + 2 = -2
Applying the same process to the second row of A, we get:
(-1 * 2) + (3 * 3) = -2 + 9 = 7
(-1 * 4) + (3 * 1) = -4 + 3 = -1
Combining these results, we obtain the matrix AB:
[-2 4]
[-1 7]
Comparing this with the options provided, the correct answer is b. [-6 14][-7 12][-3 5].

For each of the functions f1, f 2 , f 3 , determine whether it is injective, surjective, and/or bijective. In the case of negative answers, provide a suitable reason.
Among the given functions, f1 is injective and surjective (bijective), f2 is surjective but not injective, and f3 is neither injective nor surjective.
To determine whether a function is injective, we need to check if each element in the domain maps to a unique element in the codomain. A function is surjective if every element in the codomain is mapped to by at least one element in the domain. If a function is both injective and surjective, it is bijective.
For f1, we see that each element in the domain S is mapped to a unique element in the codomain S. Also, every element in the codomain is mapped to by at least one element in the domain. Therefore, f1 is both injective and surjective (bijective).
For f2, we notice that the element 'd' in the domain is mapped to by both 'b' and 'c' in the codomain, violating the condition for injectivity. However, every element in the codomain is mapped to by at least one element in the domain, satisfying the condition for surjectivity. Therefore, f2 is surjective but not injective.
For f3, we observe that all elements in the codomain are mapped to 'b' in the domain, violating the condition for surjectivity. Additionally, 'b' in the domain is mapped to by multiple elements ('b', 'c', and 'd') in the codomain, violating the condition for injectivity. Therefore, f3 is neither injective nor surjective.

The time between goals (in minutes) for a professional soccer team during a recent season can be approximated by an exponential distribution with a.
(a) Probability that the time for a goal is no more than 58 minutes is to be found.
So, we have to find P(X ≤ 58)P(X ≤ 58) = 1 − e−λt
Here, t = 58 minutes∴ P(X ≤ 58) = 1 − e−λt= 1 - e^(-λ × 58)
Putting a = -λ in the formula given we get,
λ = -aλ = -(-1/75)λ = 1/75P(X ≤ 58) = 1 - e^(-(1/75) × 58)≈ 0.5582 (approx 4 decimal places)

was twice the amount borrowed at 14%. Find the amount borrowed at each rate if the annual interest was $2580
How much money was borrowed at 10%?
How much money was borrowed at 12%?
How much money was borrowed at 14%?
Answer:
10% — $550012% — $700014% — $8500Step-by-step explanation:
You want to know the amount borrowed at 10%, 12%, and 14% if the total borrowed was $21000, the total interest was $2580, and the total of amounts borrowed at 10% and 14% was double the amount borrowed at 12%.

O c. MS. re
O d. MS, w2.
The error variance is equal to either SSw (Sum of Squares within) or MSw2 (Mean Square within squared). Both options refer to the same concept of quantifying the variability within the groups or treatments.
The error variance represents the variability or dispersion of the errors or residuals in a statistical model. In analysis of variance (ANOVA), it is commonly referred to as the "within-group" variability. It quantifies the differences between the observed values and the predicted values within each group or treatment level.
In ANOVA, the total variability in the data is partitioned into different sources, including the variability due to the treatment effect (SSb - Sum of Squares between) and the residual or error variability (SSw - Sum of Squares within). The error variance is a measure of the average squared difference between the observed values and the predicted values within each group, taking into account the degrees of freedom.
The error variance can be represented as SSw or MSw2, depending on whether we are considering the sum of squares or the mean square. Therefore, the correct options for the error variance are either b) SSw or d) MSw2.

The row echelon form of the matrix for the given system of equations is:
[1 2 6 | 2]
[0 -1 (2k + 0) | 0]
[0 0 (k - 12) | 1]
To determine the values of k that result in no solution, infinite solutions, or a unique solution, we examine the row echelon form.
(i) No Solution: If the row echelon form has a row of the form [0 0 ... 0 | c], where c is a nonzero constant, then the system is inconsistent and has no solution. In this case, for no solution, k - 12 must be nonzero, so k ≠ 12.
(ii) Infinite Solutions: If the row echelon form has a row of the form [0 0 ... 0 | 0], then the system has infinitely many solutions. Here, k - 12 = 0, which means k = 12.
(iii) Unique Solution: If the row echelon form does not have any rows of the form [0 0 ... 0 | c], where c is nonzero, then the system has a unique solution. For a unique solution, k ≠ 12.
The system has no solution when k ≠ 12, infinite solutions when k = 12, and a unique solution when k ≠ 12.

Consider the following system of equations: (2x – k²y = 3) (4x + 2y = -7 ) (a) For what value(s) of k will this system of equations have no solution? (b) Use matrix methods to solve this system of equations if k = 5
(a) The system of equations will have no solution when the value of k is ±√6. (b) Using matrix methods, when k = 5, the system of equations can be solved by representing the system in matrix form and applying Gaussian elimination to obtain the values of x and y.
(a) To determine when the system of equations has no solution, we need to find the value(s) of k that make the system inconsistent. In this case, we can focus on the first equation, 2x - k²y = 3. If the value of k satisfies k² = 6, then the equation becomes 2x - 6y = 3. The coefficient of y in the equation is -6, which means it is impossible to balance the equation with the coefficient 2 of x. Therefore, for k = ±√6, the system of equations has no solution.
(b) To solve the system of equations using matrix methods when k = 5, we can represent the system in matrix form as:
⎡ 2 -k²⎤ ⎡ x ⎤ ⎡ 3 ⎤
⎢ 4 2 ⎥ ⎢ y ⎥ = ⎢-7 ⎥
Substituting k = 5, we have:
⎡ 2 -25⎤ ⎡ x ⎤ ⎡ 3 ⎤
⎢ 4 2 ⎥ ⎢ y ⎥ = ⎢-7 ⎥
Applying Gaussian elimination to the augmented matrix, we can perform row operations to transform the matrix into row-echelon form. This process leads to the following row-echelon matrix:
⎡ 2 -25⎤ ⎡ x ⎤ ⎡ 3 ⎤
⎢ 0 52 ⎥ ⎢ y ⎥ = ⎢-13 ⎥
From the row-echelon form, we can determine that x = 1 and y = -1. Therefore, when k = 5, the solution to the system of equations is x = 1 and y = -1.

Question 3 (20 marks] Consider two utility functions u(x) and ū(x) where x is the amount of money consumed by the agent. a) Explain formally what it means that an agent with utility function u is more risk averse than an agent with utility function ũ. b) Show that an agent with utility function u(x) = log x is more risk averse than an agent with utility function ū(x) = Vă. = =
we cannot definitively conclude that u(x) = log x is always more risk-averse than ū(x) = Vă. It depends on the value of 'a' chosen for the ū(x) utility function.
a) In formal terms, an agent with utility function u(x) is considered more risk-averse than an agent with utility function ū(x) if u(x) exhibits decreasing absolute risk aversion (DARA), while ū(x) exhibits increasing absolute risk aversion (IARA).
Decreasing absolute risk aversion (DARA) implies that the agent's marginal utility of consumption diminishes as the level of wealth (x) increases. This means that as the agent accumulates more wealth, the additional satisfaction or utility gained from each additional unit of wealth diminishes. In other words, the agent values each additional dollar less and less.
On the other hand, increasing absolute risk aversion (IARA) implies that the agent's marginal utility of consumption increases as the level of wealth (x) increases. This means that the agent places higher value on each additional unit of wealth as they accumulate more. In this case, the agent is more willing to take risks to increase their wealth because the marginal utility gained from each additional unit of wealth is increasing.
b) To show that an agent with utility function u(x) = log x is more risk-averse than an agent with utility function ū(x) = Vă, we can compare their respective risk aversion properties.
The marginal utility of u(x) = log x can be calculated as u'(x) = 1/x. Notice that the marginal utility is inversely proportional to x, meaning that as x increases, the marginal utility decreases. This indicates decreasing absolute risk aversion (DARA) since the agent values each additional unit of wealth less as they accumulate more.
For the utility function ū(x) = Vă, the marginal utility can be calculated as ū'(x) = V'ă = a × [tex]x^{a-1}[/tex]. Here, 'a' is a constant parameter. If we consider a > 1, the marginal utility will also decrease as x increases, indicating decreasing absolute risk aversion (DARA). However, if we consider a < 1, the marginal utility will increase as x increases, indicating increasing absolute risk aversion (IARA).
Since we are comparing u(x) = log x (DARA) with ū(x) = Vă, where the risk aversion depends on the specific value of 'a,' we cannot definitively conclude that u(x) = log x is always more risk-averse than ū(x) = Vă. It depends on the value of 'a' chosen for the ū(x) utility function.

Let f(x)=√42-z and g(x)=x²-x. Then the domain of f o g=________
The domain of the composition function f o g is all real numbers except for the values of x that make g(x) negative or result in a non-real output for f(g(x)).
The composition function f o g is obtained by substituting g(x) into f(x), so we have f(g(x)) = √42 - (x² - x).
To find the domain, we need to consider two factors: the domain of g(x) and the restrictions on the output of f(g(x)).
The domain of g(x) is all real numbers since x can take any value. However, when substituting g(x) into f(x), we need to ensure that the resulting expression is defined and real.
The expression inside the square root, 42 - (x² - x), should be non-negative for the function to be defined. This implies that 42 - (x² - x) ≥ 0. Solving this inequality, we get x² - x - 42 ≤ 0.
Factoring the quadratic equation, we have (x - 7)(x + 6) ≤ 0. The solution to this inequality is -6 ≤ x ≤ 7.
Therefore, the domain of f o g is the interval [-6, 7], which includes all real numbers between -6 and 7, inclusive.

[tex]P(X_1 < X_2 | X_1 < 2X_2) =[/tex][tex]\int (0\ to\ \infty) \int (x_1 to 2x_1) * f(x_1, x_2) dx_2 dx_ / \int (0\ to\ \infty) \int (x \ to\ \infty) f(x_1, x_2) dx_2 dx_1[/tex]
Simplifying the integrals and performing the calculations, we can evaluate the conditional probability as 1/3.
(b) To evaluate [tex]P(X_1 < X_2 < X_3 | X_3 < 1)[/tex], we can follow a similar approach. We find the joint pdf of [tex](X_1, X_2, X_3)[/tex] and calculate the conditional probability.
The joint pdf of [tex](X_1, X_2, X_3)[/tex] is given by [tex]f(x_1, x_2, x_3) = f(x_1) * f(x_2) * f(x_3) = exp(-x_1) * exp(-x_2) * exp(-x_3) = exp(-(x_1 + x_2 + x_3))[/tex], where [tex]x_1 > 0, x_2 > 0, x_3 > 0.[/tex]
To find [tex]P(X_1 < X_2 < X_3 | X_3 < 1)[/tex], we need to find the region where [tex]X_1 < X_2 < X_3 and X_3 < 1.[/tex] This occurs when [tex]0 < x_1 < x_2 < x_3 < 1.[/tex]
Integrating the joint pdf over this region and dividing by the probability of the event [tex]X_3 < 1[/tex], we get:
[tex]P(X_1 < X_2 < X_3 | X_3 < 1)[/tex] [tex]=[/tex] [tex]\int (0 to 1) \int (0 to x_3) \int (0 to x_2) f(x_1, x_2, x_3) dx_1 dx_2 dx_3 / \int (0 to 1) \int (0 to x) \\*\int (0 to x2) f(x_1, x_2, x_3) dx_1 dx_2 dx_3[/tex]
Simplifying the integrals and performing the calculations, we can evaluate the conditional probability as 1/6.
