The substitution is u = -x² + 9 and the evaluated value is -4.5(2/3)(-x² + 9)³/² + C.

To evaluate the given integral ∫9x√(-x² + 9dx),

we can use the substitution u = -x² + 9. This substitution will allow us to simplify the expression under the square root.

First, we can find du/dx by taking the derivative of u with respect to x: du/dx = -2x.

Next, we can solve for dx in terms of du by dividing both sides by -2x: dx = -du/(2x).

Using the substitution and the expression for dx in terms of du, we can rewrite the integral as:

∫9x√(-x² + 9dx) = -4.5∫√udu

Now, we can integrate the simplified expression √u using the power rule of integration:

-4.5∫√udu = -4.5(2/3)u³/² + C

Substituting back for u, we get:

-4.5(2/3)(-x² + 9)³/² + C

Therefore, the solution to the integral ∫9x√(-x^2 + 9dx) using the substitution u = -x^2 + 9 is:

-4.5(2/3)(-x² + 9)³/² + C

Gabriela will use 1620 square inches of wood to build the open box.

The amount of wood Gabriela will use depends on the surface area of the box, which is the sum of the areas of its six faces. Since the box is open on top, it will have five faces: four sides and a bottom.

The area of the bottom is the area of a rectangle with length 18 in. and width 15 in., which is:

Area of bottom = length x width = 18 in. x 15 in. = 270 in²

The area of each side is the product of the height and the length of the corresponding base, which is:

Area of each side = height x length = 15 in. x 18 in. = 270 in²

So the total surface area of the box is:

Total surface area = 2 x (Area of bottom) + 4 x (Area of each side)

= 2 x 270 in² + 4 x 270 in²

= 1620 in²

Therefore, Gabriela will use 1620 square inches of wood to build the open box.

To express u = (7, -10) as a linear combination u = rv + sw, where v = (2, 1) and w = (1,4), we need to find the values of r and s such that:

u = rv + sw

Substituting the given values, we get:

(7, -10) = r(2, 1) + s(1,4)

Using the symbolic notation, we can write this as a system of equations:

7 = 2r + s
-10 = r + 4s

We can solve this system of equations by using the elimination method:

Multiply the second equation by 2:

7 = 2r + s
-20 = 2r + 8s

Subtracting the first equation from the second, we get:

-27 = 7s

Dividing both sides by 7, we get:

s = -27/7

Substituting this value of s into the first equation, we get:

7 = 2r - 27/7

Multiplying both sides by 7, we get:

49 = 14r - 27

Adding 27 to both sides, we get:

76 = 14r

Dividing both sides by 14, we get:

r = 38/7

Therefore, u = (7, -10) can be expressed as the linear combination:

u = (38/7)(2,1) + (-27/7)(1,4)

Using fractions where needed, the answer is:

u = (76/7, 38/7) + (-27/7, -108/7)

y = 6

Sorry for bad handwriting

if i was helpful Brainliests my answer ^_^

The value of Y in the equation Y/4 = 3/2 is 6.

To find the value of Y, we'll use the following steps:

1. We start with the given equation:

Y/4 = 3/2.

2. Our goal is to isolate Y. To do this, we'll multiply both sides of the equation by 4, which is the denominator on the left side.

3. Multiplying both sides by 4 gives us: (Y/4) * 4 = (3/2) * 4.

4. On the left side, the 4s cancel out, leaving just Y: Y = (3/2) * 4.

5. Now, we simplify the right side by multiplying 3/2 by 4. We can think of 4 as 4/1, so the equation becomes: Y = (3/2) * (4/1).

6. Multiply the numerators (3*4) and denominators (2*1) separately: Y = (12/2).

The area of ΔEFG is approximately 6.7 square centimeters.

To find the area of ΔEFG with given sides g = 5.2 cm, e = 5.1 cm, and ∠F = 42°, you can use the formula for the area of a triangle when two sides and the included angle are known. This formula is:

Area = (1/2)ab * sin(C)

In this case, a = g, b = e, and C = ∠F. Plug in the values:

Area = (1/2)(5.2 cm)(5.1 cm) * sin(42°)

Area ≈ 6.675 square centimeters

So, the area of ΔEFG is approximately 6.7 square centimeters to the nearest 10th of a square centimeter.

The interquartile range (IQR) of the given data set is 4.

Interquartile range (IQR) is a measure of variability in a data set that measures the spread of the middle 50% of the data. It is calculated as the difference between the third quartile (Q3) and the first quartile (Q1).

To find the interquartile range (IQR), we first need to find the median of the data set.

The median is the middle value of the dataset when the data is arranged in order. In this case, the data set is already in order, so the median is the middle value or the average of the two middle values:

Median = (26 + 28) / 2 = 27

Now, we need to find the first quartile (Q1) and the third quartile (Q3) of the data set.

Q1 is the median of the lower half of the data set, and Q3 is the median of the upper half of the data set.

Lower half: 22, 24, 26

Upper half: 28, 30

Q1 = median of the lower half = (24 + 26) / 2 = 25

Q3 = median of the upper half = (28 + 30) / 2 = 29

Now we can find the IQR:

IQR = Q3 - Q1 = 29 - 25 = 4

Therefore, the interquartile range (IQR) of the given data set is 4.

A reasonable estimate for the amount of flour and sugar combined is approximately 0.36 kg.

To determine a reasonable estimate for the amount of flour and sugar combined, we first need to add the fractions 1/4 and 2/9. To do this, we need to find a common denominator. The least common multiple of 4 and 9 is 36. We can convert 1/4 to 9/36 by multiplying both the numerator and denominator by 9. We can also convert 2/9 to 4/36 by multiplying both the numerator and denominator by 4. Now we can add the fractions:

9/36 + 4/36 = 13/36

So Ellen mixed 13/36 kg of flour and sugar combined. To convert this to a decimal, we can divide the numerator by the denominator:

13 ÷ 36 ≈ 0.36

Therefore, a reasonable estimate for the amount of flour and sugar combined is approximately 0.36 kg.

Let's define the variables:

x =  number of dimes

y = number of quarters.

There are 25 coins, so:

x + y = 25

The value is $3.85, so:

x*0.10 + y*0.25 = 3.85

So the system of equations is:

x + y = 25

x*0.10 + y*0.25 = 3.85

We can isolate x on the first equation to get:

x = 25 - y

Replacing that in the other one we get:

(25  -y)*0.10 + y*0.25 = 3.85

Let's use the given terms and find out the percentage profit if the farmer had sold the goat for 2100 shillings.
Calculate the cost price of the goat
We know that the farmer made a loss of 28% by selling the goat for 1440 shillings. Let's represent the cost price as "CP".

We can write the equation:
[tex]CP \times  (1 - loss% ) = selling price (SP)[/tex]
[tex]CP \times  (1 - 0.28) = 1440[/tex]
Solve for CP
[tex]CP \times 0.72 = 1440[/tex]
CP = 1440 / 0.72
CP = 2000 shillings
Calculate the percentage profit
Now we want to find out the percentage profit if the farmer had sold the goat for 2100 shillings.

We can write the equation:
[tex](SP_{new - CP)} / CP \times  100 = profit[/tex]

Cost is the most significant factor to determine success when you are operating a business. You need to understand different cost factors and how it affects profitability. We define costs as the value of money required to produce a product or deliver goods. In this section, we have explained different cost definitions.

If each lesson costs $13 and Lucas attends "n" lessons, then the total cost for the lessons will be 13n dollars.

Now, let's consider the cost of the bus rides. Lucas takes the bus to each lesson, so he takes "n" bus rides in total. If each bus ride costs X dollars, then the total cost of the bus rides will be Xn dollars.

Finally, Lucas walks home after each lesson, so there is no cost associated with walking.

Therefore, the expression that represents the total cost for Lucas to attend the lessons if each bus ride costs X dollars is:

13n + Xn = (13+X)n

So If each lesson costs $13 and Lucas attends "n" lessons, then the total cost for the lessons will be 13n dollars.

To find the total cost, we need to integrate the marginal cost function from 0 to 20, which will give us the total variable cost. We can then find the fixed cost by subtracting the total variable cost from the initial cost C(0), which is given in the problem.

The marginal cost function for a company is given by C'(q) = [tex]q^2[/tex] - 17q + 70 dollars/unit; where q is the quantity produced. If C(0) = 650, then total cost of producing 20 units = 2,600 dollars. Fixed cost for the quantity = 650 dollars. Variable Cost of producing 20 units = 1,950 dollars

To find the total cost function C(q), integrate the marginal cost function C'(q):

C(q) = ∫[tex](q^2 - 17q + 70)[/tex] dq = [tex](1/3)q^3 - (17/2)q^2 + 70q + K[/tex]

To find the constant K, use the given information: C(0) = 650

650 = [tex](1/3)(0)^3 - (17/2)(0)^2 + 70(0) + K[/tex]
K = 650

So the total cost function is:

C(q) = [tex](1/3)q^3 - (17/2)q^2 + 70q + 650[/tex]

Now, we find the total cost of producing 20 units:

C(20) = [tex](1/3)(20)^3 - (17/2)(20)^2 + 70(20) + 650[/tex]
C(20) = 2,600

Total cost of producing 20 units = 2,600 dollars.

Fixed cost is the cost incurred when producing 0 units, which is given as C(0) = 650 dollars.

To find the total variable cost for producing 20 units, subtract the fixed cost from the total cost:

Variable Cost = Total Cost - Fixed Cost
Variable Cost = 2,600 - 650
Variable Cost = 1,950 dollars

To summarize:
Fixed cost = 650 dollars
Variable cost of producing 20 units = 1,950 dollars

Calculated test statistic of 2.08 is greater than the critical value of 1.645, we reject the null hypothesis and conclude that there is convincing evidence at the 0.05 level that more than 55% of California residents use Netflix.

We can use a hypothesis testing approach to answer this question. The null hypothesis is that the true proportion of California residents who use Netflix is the same as the national proportion, or p = 0.55. The alternative hypothesis is that the true proportion of California residents who use Netflix is greater than 0.55, or p > 0.55.

We can use the sample proportion of Netflix users in California, which is 360/600 = 0.6, as an estimate of the true proportion p. The standard error of the sample proportion is:

SE = √[(p*(1-p))/n] = √[(0.55*(1-0.55))/600] = 0.024

The test statistic is:

z = (p - 0.55)/SE = (0.6 - 0.55)/0.024 = 2.08

Assuming a significance level of 0.05 and a one-tailed test (since the alternative hypothesis is one-sided), the critical z-value is 1.645.

Since our calculated test statistic of 2.08 is greater than the critical value of 1.645, we reject the null hypothesis and conclude that there is convincing evidence at the 0.05 level that more than 55% of California residents use Netflix. However, we should keep in mind that this conclusion is based on a sample of 600 adults from California, and there is always some degree of uncertainty involved in statistical inference based on samples.
