A car-detailing service estimates that its daily cost of waxing a cars is C(q) = 0.06q²+37q + 360, If the service collects $65 for each car waxing, find the number of cars the service should wax daily in order to maximize profit

Answers

Answer 1

The service should wax approximately 233 cars daily to maximize profit.

To maximize profit, we need to find the number of cars (q) that would result in the highest profit. Profit function P(q) can be calculated as:

P(q) = Revenue - Cost
P(q) = 65q - (0.06q² + 37q + 360)

Now, to find the optimal value of q, we can calculate the derivative of the profit function with respect to q and set it to zero:

dP(q)/dq = 65 - (0.12q + 37)
0 = 65 - 0.12q - 37

Solve for q:

0.12q = 28
q = 28 / 0.12
q ≈ 233.33

Since the number of cars must be a whole number, we can round q to the nearest integer. Therefore, the service should wax approximately 233 cars daily to maximize profit.

For the acute angles in a right triangle, sin(5x)° = cos(3x + 2)°.


What is the number of degrees in the measure of the smaller


angle?

Answers

Answer is The smaller angle is 35°.


To solve for the acute angles in a right triangle when sin(5x)° = cos(3x + 2)°, we need to use trigonometric identities.

Recall that sin(x) = cos(90 - x) for any angle x. Using this identity, we can rewrite sin(5x)° as cos(90 - 5x)°.

Similarly, cos(x) = sin(90 - x) for any angle x. Using this identity, we can rewrite cos(3x + 2)° as sin(90 - (3x + 2))°, which simplifies to sin(88 - 3x)°.

Now we have cos(90 - 5x)° = sin(88 - 3x)°. Since these two expressions are equal, we can set them equal to each other and solve for x:

cos(90 - 5x)° = sin(88 - 3x)°

sin(5x)° = sin(88 - 3x)°

5x = 88 - 3x

8x = 88

x = 11

Therefore, the acute angles in the right triangle are 5x° and 90 - 5x°, or 55° and 35°. The smaller angle is 35°.

Find the particular solution for:
f"(x) = 0.25x⁻³/², f'(4) = - 1/8 and f(0) = 2.

Answers

The particular solution for f(x) is:

f(x) = (2/3)x³/² - (17/8)x + 2

How to find the particular solution of f(x)?

We will integrate the given differential equation twice and use the initial conditions to find the constants of integration.

Given: f"(x) = 0.25x⁻³/²

Integrating once, we get:

f'(x) = ∫(0.25x⁻³/²) dx = 0.5x¹/² + C₁

where C₁ is the constant of integration.

Using the initial condition f'(4) = -1/8, we can solve for C₁:

f'(4) = 0.5(4)¹/² + C₁ = 2 + C₁ = -1/8

C₁ = -1/8 - 2 = -17/8

So,

f'(x) = 0.5x¹/² - 17/8

Integrating again, we get:

f(x) = ∫(0.5x¹/² - 17/8) dx = (2/3)x³/² - (17/8)x + C₂

where C₂ is the second constant of integration.

Using the initial condition f(0) = 2, we can solve for C₂:

f(0) = (2/3)(0)³/² - (17/8)(0) + C₂ = 2

C₂ = 2

So, the particular solution for f(x) is:

given a prism with a right triangle base and the dimensions and what is a correct expression for the volume of the prism?

Answers

The correct expression for the volume of a prism with a right triangle base can be obtained by multiplying the area of the base by the height of the prism. For a right triangle base, the area can be calculated as half the product of the base and height of the triangle, given by the formula A = (1/2)bh.

Let's say the dimensions of the right triangle base are b and h, and the height of the prism is denoted by H. Then, the volume of the prism can be expressed as V = A × H = (1/2)bh × H = (bhH)/2.

This expression represents the volume of the prism in terms of its base dimensions and height. It is important to note that the units of the dimensions should be consistent in order to get the volume in a suitable unit. For example, if the base dimensions are in centimeters and the height is in meters, the volume should be converted to cubic meters or cubic centimeters depending on the required accuracy.

In conclusion, the volume of a prism with a right triangle base can be calculated by multiplying the area of the base by the height of the prism. For a right triangle base, the area is given by (1/2)bh, and the volume can be expressed as (bhH)/2.

Answers

The area of glass value is 0.18 square meters.

The longer diagonal of the kite-shaped window has a measure of 25 cm + 35 cm = 60 cm.

Juliet wants to know if the chicken broth in this beaker will fit into this rectangular food storage container. Explain how you would figure it out without pouring the contents in. If it will fit, how much more broth could the storage container hold? If it will not fit, how much broth will be left over? (Remember: 1 cm = 1 mL. )

Answers

The container could hold an additional 870 mL of broth if it is already holding the 90 mL of broth from the beaker.

To figure out if the chicken broth in the beaker will fit into the rectangular food storage container, we need to compare the volume of the beaker to the volume of the container.

The volume of the beaker can be calculated by multiplying its base area (which is the same as the area of the circle at the bottom of the beaker) by its height. The volume of the container can be calculated by multiplying its length, width, and height.

If the volume of the beaker is less than or equal to the volume of the container, then the chicken broth will fit. If it is greater, then the chicken broth will not fit.

To find out how much more broth the container could hold if it fits, we can subtract the volume of the beaker from the volume of the container.

For example, if the beaker has a diameter of 6 cm and a height of 10 cm, then its volume would be:

V_beaker = πr^2h = π(3^2)(10) = 90π cm^3 = 90 mL

If the rectangular food storage container has dimensions of 12 cm x 8 cm x 10 cm, then its volume would be:

V_container = lwh = 12(8)(10) = 960 cm^3 = 960 mL

Since 90 mL (the volume of the beaker) is less than 960 mL (the volume of the container), the chicken broth will fit in the container. The amount of broth the container can hold in addition to the beaker's contents would be:       960 mL - 90 mL = 870 mL

Ben makes orange paint by mixing red, yellow and white paint in the ratio 20 : 16 : 1. 5. How much of each colour does he need to make 1. 5 litres of orange paint?​

Answers

Using the ratio, we solve and get, Ben needs 0.8 litres of red paint, 0.64 litres of yellow paint, and 0.06 litres of white paint to make 1.5 litres of orange paint.

To make 1.5 litres of orange paint, Ben needs to mix the red, yellow, and white paint in the ratio of 20 : 16 : 1.5.

To calculate the amount of each color needed, you first need to find the total number of parts in the ratio.

The total number of parts is 20 + 16 + 1.5 = 37.5.

Next, you can calculate the amount of each color needed by dividing 1.5 litres by the total number of parts in the ratio, and then multiplying by the respective parts for each color.

So, the amount of red paint needed is:

(1.5/37.5) x 20 = 0.8 litres

The amount of yellow paint needed is:

(1.5/37.5) x 16 = 0.64 litres

And the amount of white paint needed is:

(1.5/37.5) x 1.5 = 0.06 litres

urgent

Answers

The height of the trapezoidal tabletop is approximately 59.5 centimeters.

To calculate the height of a trapezoid with the given measurements, we need to use the formula for the area of a trapezoid: A = (b1 + b2)h / 2, where A is the area, b1 and b2 are the lengths of the two bases, and h is the height.

In this problem, the area (A) is 7,021 square centimeters, the longer base (b1) is 131 centimeters, and the shorter base (b2) is 105 centimeters. Our task is to find the height (h).

First, let's plug the given values into the formula:

7,021 = (131 + 105)h / 2

Now, simplify the equation:

7,021 = 236h / 2

To solve for h, multiply both sides of the equation by 2:

14,042 = 236h

Finally, divide both sides by 236:

h ≈ 59.5

Answers

The volume of the box is 160 cubic inches. Using the volume of a rectangular prism formula the volume of the box is 160 cubic inches. Using another formula base area times height, the area is the same.

The volume of James' rectangular prism box can be calculated using both unit cubes and a formula. Part (a) involves counting the unit cubes in the model and multiplying the number of cubes by their volume, which is 1 cubic inch. In this case, there are 160 unit cubes, so the volume of the box is 160 cubic inches.

Part (b) involves using the formula for volume of a rectangular prism, which is length times width times height. Plugging in the given dimensions, we get 8 x 4 x 5 = 160 cubic inches, which is the same as the answer in part (a) using unit cubes.

Part (c) involves using a different formula for volume, which is base area times height. In this case, the base of the rectangular prism is a rectangle with length 8 inches and width 4 inches, so the base area is 8 x 4 = 32 square inches. Multiplying by the height of 5 inches, we get 160 cubic inches, which is again the same as the answers in parts (a) and (b).

Using the volume formulas is much quicker and more efficient than counting unit cubes, especially for larger boxes. However, counting unit cubes can provide a more concrete visual representation of the volume and can be helpful for students who are just learning about volume.

She wins $1 if the number 1 is selected, $2 if the number 2 is selected, $3 if the number 3 is selected, $4 if the number 4 is selected, and $5 if the number 5 is selected. She loses $1 if 6, 7, or 8 is selected.


(a) Find the expected value of playing the game. Dollars


(b) What can Latoya expect in the long run, after playing the game many times? (She replaces the ball in the bag each time. ) Latoya can expect to gain money. She can expect to win dollars per selection. Latoya can expect to lose money. She can expect to lose dollars per selection. Latoya can expect to break even (neither gain nor lose money)

Answers

Latoya may experience some fluctuations in her winnings and losses in the short run, in the long run, her average winnings will approach $0.50 per selection.

What is the expected value of playing the game and what Latoya can expect after playing the game many times?

(a) To find the expected value of playing the game, we need to multiply the amount that Latoya can win or lose by the probability of each outcome, and then add up the results. Let p(i) be the probability of selecting the ball with the number i. Since there are 8 balls in total and each ball is equally likely to be selected, we have:

p(i) = 1/8 for i = 1, 2, ..., 8

Now we can calculate the expected value:

E(X) = ∑[i=1 to 5] (i * p(i)) + ∑[i=6 to 8] (-1 * p(i))

= (1/8)(1) + (1/8)(2) + (1/8)(3) + (1/8)(4) + (1/8)(5)

- (1/8)(1) - (1/8)(1) - (1/8)(1)

= 0.5

Therefore, the expected value of playing the game is $0.50.

(b) In the long run, after playing the game many times, Latoya can expect to break even (neither gain nor lose money) on average per selection. This means that over a large number of selections, she can expect to win some money on some selections and lose some money on others, but on average, her total winnings and losses will balance out to zero.

To see why this is the case, consider that the expected value of a single selection is $0.50. If Latoya plays the game many times, the law of large numbers tells us that the average winnings per selection will converge to the expected value of $0.50. So even though Latoya may experience some fluctuations in her winnings and losses in the short run, in the long run, her average winnings will approach $0.50 per selection.

Using the federal list, the total amount of exemptions that Jerry would be allowed is $25,150.


Jerry's assets include a house with equity of $15,000, a car with equity of $2,500, household goods worth $6,000 (no single item over $400), and tools worth $5,800 that he needs for his business.


Using the state list, the total amount of exemptions that Jerry would be allowed varies depending on the state in which he resides. Without knowing the state, it is impossible to provide an accurate answer. However, it is worth noting that the state list is often more favorable for individuals than the federal list.

Draw the image of ABC under the translation by 1 unit to the right and 4 units up

Answers

The image of ABC under the translation by 1 unit to the right and 4 units up is the triangle with vertices A', B', and C'.

What is Triangle?

A triangle is a closed two-dimensional geometric shape with three straight sides and three angles. It is one of the basic shapes in geometry and has been studied since ancient times. To translate a figure by a given vector, you need to move each point of the figure by the same amount and in the same direction as the vector. In this case, we want to translate ABC by a vector of (1, 4), which means we need to move each point of ABC one unit to the right and four units up.

Let's say the coordinates of the points of ABC are:

A = [tex]\rm (x_1, y_1)[/tex]

B = [tex]\rm (x_2, y_2)[/tex]

C = [tex]\rm (x_3, y_3)[/tex]

To translate ABC by the vector (1, 4), we add 1 to each x-coordinate and 4 to each y-coordinate:

A' = [tex]\rm (x_1 + 1, y_1 + 4)[/tex]   (x₁ + 1, y₁ + 4)

B' = [tex]\rm (x_2 + 1, y_2 + 4)[/tex]   (x₂ + 1, y₂ + 4)

[tex]\rm C' = (x_3 + 1, y_3 + 4)[/tex]  (x₃ + 1, y₃ + 4)

Therefore, The image of ABC under the translation by 1 unit to the right and 4 units up is the triangle with vertices A', B', and C'.

Ms. paquette put one coat of paint on a rectangular wall that measured 25 1/2 ​ feet by 10 feet. the paint that she bought was sold in 1-gallon containers.

Answers

Ms. Paquette used approximately 0.73 gallons of paint for one coat on the rectangular wall.

To determine how many gallons of paint Ms. Paquette used for one coat on the rectangular wall, we first need to calculate the total area of the wall.

Area of the wall = length x width
= 25.5 feet x 10 feet
= 255 square feet

Now, to find out how many gallons of paint are needed for one coat, we need to know the coverage rate of the paint. This information is usually provided on the paint can label. Let's assume that the coverage rate for the paint Ms. Paquette used is 350 square feet per gallon.

To calculate how many gallons of paint are needed, we can divide the total area of the wall by the coverage rate of the paint:

255 square feet ÷ 350 square feet per gallon = 0.7286 gallons

This means that Ms. Paquette used approximately 0.73 gallons of paint for one coat on the rectangular wall. Since paint is typically sold in 1-gallon containers, she would need to purchase at least one gallon of paint to complete one coat on this wall.

A velociraptor runs 5m [e] , 10 m [w], 3m [s], & 2m [w] in 10 seconds. calculate speed & velocity.

Answers

The velociraptor's speed is 2 m/s, and its velocity is -0.3 m/s [w].

What is the total distance covered?


To calculate the speed and velocity of the velociraptor, we need to first find the total distance it covered and the displacement.

Total distance = 5m + 10m + 3m + 2m = 20m

Displacement = Final position - Initial position

Displacement = (2m [w]) - (5m [e])

Displacement = -3m [w]

Velocity is defined as displacement per unit time, while speed is defined as distance per unit time.

Velocity = Displacement / Time

Velocity = -3m [w] / 10s

Velocity = -0.3 m/s [w]

Speed = Total distance / Time

Speed = 20m / 10s

Speed = 2 m/s

Therefore, the velociraptor's speed is 2 m/s, and its velocity is -0.3 m/s [w].

Answers

Answer:

N'(3, 2), M'(0, 1), O'(1, 3)

Step-by-step explanation:

Please sketch the graphs of the two triangles and the line of reflection to confirm my answer.

Since NMO is reflected over the line

x = -1, the y-coordinates of N'M'O' will remain the same. Since the x-coordinate of N is at -5, which is 4 units to the left of the line of reflection, the x-coordinate of N' is at -1 + 4 = 3. Since the x-coordinate of M is at -2, which is 1 unit to the left of from the line of reflection, the x-coordinate of M' is at -1 + 1 = 0. Since the x-coordinate of O is at -3, which is 2 units to the left of the line of reflection, the x-coordinate of O' is at -1 + 2 = 1. So the vertices of N'M'O' are at (3, 2), (0, 1), and (1, 3).

2 Liam bought too much fencing and had 26 feet of it left over. He and his brother


decided to make a rectangle-shaped garden patch for their little sister. They wanted


to use all the extra fencing to outline her garden patch. What could be the dimen-


sions of the patch they make for their sister? (Use only whole numbers of feet. )


Show all your work. ​

Answers

The perimeter is indeed 26 feet, which means they have used all the extra fencing.

Let's start by assuming that the length and width of the garden patch are whole numbers of feet, since we are asked to use only whole numbers.

Let's call the length of the garden patch "L" and the width "W".

We know that Liam has 26 feet of fencing left over. This fencing will be used to make the perimeter of the garden patch, which is given by:

Perimeter = 2L + 2W

We can substitute the value of the perimeter with the amount of fencing that Liam has:

26 = 2L + 2W

Simplifying this equation, we get:

13 = L + W

Since we want to use all the extra fencing, we know that the perimeter of the garden patch must be 26 feet. We can use this information to write another equation:

Perimeter = 2L + 2W = 26

We can substitute the value of 13 for L + W in this equation:

2L + 2W = 26

2L + 2(13-L) = 26

2L + 26 - 2L = 26

26 = 26

This equation is true, which means that our assumption that L and W are whole numbers is correct.

Therefore, the dimensions of the garden patch that Liam and his brother can make for their sister are 6 feet by 7 feet.

To check, we can calculate the perimeter:

Perimeter = 2L + 2W = 2(6) + 2(7) = 12 + 14 = 26

So the perimeter is indeed 26 feet, which means they have used all the extra fencing.

Solve the following Exact Inexact Differential Equation. If it is inexact, then
solve it by finding the Integrating Factor.
(3xy + y^2) dx + (x^2 + xy) dy = 0

Answers

The general solution to the differential equation is, |3x^4/(y(x+y))|x + |x^3| ln|y| + |x^3| ln|x+y| + h(x) = C.

The partial derivative of (3xy + y^2) with respect to y is 6xy + 2y, and the partial derivative of (x^2 + xy) with respect to x is 2x + y. Since these are not equal, the differential equation is not exact.

To make it exact, we need to find an integrating factor μ(x, y) such that μ(x, y)(3xy + y^2) dx + μ(x, y)(x^2 + xy) dy = 0 is exact. We can find μ(x, y) by using the formula:

μ(x, y) = e^(∫(∂M/∂y - ∂N/∂x)/N dx)

where M = 3xy + y^2 and N = x^2 + xy. We have:

(∂M/∂y - ∂N/∂x)/N = (6xy + 2y - 2x - y)/(x^2 + xy) = (6xy - x - y)/(x^2 + xy)

We can now find the integrating factor μ(x, y) by integrating this expression with respect to x:

μ(x, y) = e^(∫(6xy - x - y)/(x^2 + xy) dx) = e^(3ln|x| - ln|y| - ln|x+y| + C) = e^(ln|x^3/(y(x+y))| + C) = |x^3/(y(x+y))|e^C

where C is the constant of integration.

Now we multiply the original differential equation by the integrating factor μ(x, y) to obtain:

|3x^4/(y(x+y))| dx + |x^3/(y(x+y))| dy = 0

This is now an exact differential equation, and we can find its solution by integrating with respect to x or y. Integrating with respect to x, we get:

|3x^4/(y(x+y))|x + g(y) = C

where g(y) is the constant of integration. To find g(y), we integrate the coefficient of dy:

g(y) = ∫|x^3/(y(x+y))| dy = |x^3| ln|y| + |x^3| ln|x+y| + h(x)

where h(x) is another constant of integration. Substituting g(y) back into the solution, we have:

|3x^4/(y(x+y))|x + |x^3| ln|y| + |x^3| ln|x+y| + h(x) = C

This is the general solution to the differential equation.

Ghost riders co. has an eps of $1.65 that is expected to grow at 8.5 percent per year. if the pe ratio is 19.15 times, what is the projected stock price in 4 years?

Answers

The projected stock price of Ghost Rider Co. in 4 years is $45.24.

First, we need to calculate the future EPS of Ghost Rider Co. in 4 years. We can do this using the formula for the future value of an annuity:

[tex]FV = PV x (1 + r)^n[/tex]

where FV is the future value, PV is the present value, r is the growth rate, and n is the number of years.

Using this formula, we get:

[tex]FV = $1.65 x (1 + 0.085)^4 = $2.36[/tex]

Next, we can use the following formula to determine the anticipated stock price:

Estimated stock price = EPS x PE ratio

When we enter the values we have, we obtain:

Projected stock price = $2.36 x 19.15 = $45.24

Therefore, the projected stock price of Ghost Rider Co. in 4 years is $45.24.

You have talked to three managers. The first one is Bob, A departments manager, and has a set of leadership challenges. Bob is a supportive leader as seen through his interactions with workers. He remembers his followers birthdays, takes them out for lunch, and praises their performance. However, this approach does not suit their task characteristics as outlined in the path-goal model. Often times, his workers are unsure what and how to do their work. They seem to have ambiguous targets to achieve and have to work under a lot of pressure. Their work environment transforms on a regular basis, so they require a supervisor who can explain the targets. Additionally, these workers feel insecure since they do not know how to cope with the changes which is shown in the way they complain to each other about their work. This scenario requires a directive leader who will provide structure and guide them in their daily tasks. Bob ought to get more involved in his subordinates tasks so as deal with this challenge.The second manager is Arthur who is Department Bs manager, and he has different leadership challenges. His employees are dull and uninterested to work. They also know their tasks inside out. The path goal theory states that directive leadership is suitable to dogmatic subordinates who have unclear, complex and ambiguous tasks. However, B departments workers are already confident about their ability to complete tasks. Additionally, they seem to have an internal locus of control. Therefore, the last thing they need is a directive leader, yet Arthur has selected the directive leadership style. His behaviour is incompatible with his employees and well as their work environment. Thus, Arthur needs to minimize his level of involvement in the workers work. He should behave more like Bob by dealing with his subordinates human needs. Arthur ought to work on his interpersonal relationship by relating to his subordinates. These workers need a human touch because they prefer affiliation and interpersonal relationship, which is the perfect scenario for supportive leadership.Lastly, Carol, is a part-time assistant manager who comes to support the factory of Faxxcom during the peak production seasons for departments A & B, seems to have mastered her situation and her employees quite well. She is a participative leader in certain circumstances, a supportive leader at other times, and an achievement-oriented supervisor in certain circumstances.
