Carson packed his movies in a box that is in the shape of a rectangular prism. The height of the box is 17 inches. The length of the box is 1.5 times the height. The volume of the box is 5,635.5 cubic inches. What is the width of the box?
Answer:
Width: 13 inches
Step-by-step explanation:
To find the width of prism you would have to divide the volume of the prism by the area of the cross section.
First calculate the area of the cross section of the prism:
17 × 25.5= 433.5
Then divide the cross section area by the volume:
5635.5 ÷ 433.5= 13
The width is 13 inches

Suppose that a population P(t) follows the following Gompertz differential equation. dP dt = 3P(20 – In P), with initial condition P(0) = 60. (a) What is the limiting value of the population? (b) What is the value of the population when t = 3?
The limiting value of the population is approximately 485165195.41, as t approaches infinity, and the value of the population at t = 3 can be determined by solving the Gompertz differential equation with the initial condition, resulting in a specific numerical value.
(a) The limiting value of the population, as t approaches infinity, can be determined by analyzing the behavior of the Gompertz differential equation. As t increases, the term 20 - ln(P) will tend to 20, as ln(P) approaches infinity.
Therefore, the limiting value of the population can be found by setting 20 - ln(P) equal to 0 and solving for P. In this case, we can solve the equation 20 - ln(P) = 0 to find that the limiting value of the population is P = e^20, which is approximately 485165195.41.
(b) To find the value of the population when t = 3, we can use the given Gompertz differential equation. Plugging in t = 3 and the initial condition P(0) = 60, we can solve the differential equation numerically or use an appropriate method to find the value of P at t = 3.
This would require solving the equation dP/dt = 3P(20 - ln(P)) with the initial condition P(0) = 60. The resulting population value at t = 3 will depend on the specific numerical solution obtained.
In summary, the limiting value of the population is approximately 485165195.41, and the value of the population at t = 3 can be found by solving the Gompertz differential equation with the given initial condition.

The polygon shown is regular and has 9 sides. It is a regular nonagon.
Type in your answer to complete the sentence.
What is the measure of ∠F
∠
F
?
The measure of ∠F in the regular nonagon is 140 degrees.
In a regular nonagon, all angles have the same measure since it is a regular polygon. To find the measure of ∠F, we need to divide the sum of the interior angles of a nonagon by the number of sides.
The sum of the interior angles of a polygon can be found using the formula:
Sum of interior angles = (n - 2) * 180 degrees
where n represents the number of sides.
For a nonagon with 9 sides, the sum of the interior angles is:
Sum of interior angles = (9 - 2) * 180 degrees = 7 * 180 degrees = 1260 degrees.
Since all angles in a regular nonagon have the same measure, we can find the measure of ∠F by dividing the sum of the interior angles by the number of sides:
Measure of ∠F = Sum of interior angles / Number of sides = 1260 degrees / 9 = 140 degrees.
Therefore, the measure of ∠F in the regular nonagon is 140 degrees.

1. the height of a water bottle in a bathtub, w, is a function of time, t. Let P represent this function. Height is measured in inches and time is in minutes.
match each statement in function with a description.
A: P(0)=0
1. after 20 minutes, the bathtub is empty
2. the bathtub starts out with no water
3. the height of the water is 4 inches
4. the height of the water is 10 inches after 4 minutes.
3. After 10 minutes, the height of the water is 4 inches
Answer:
1) P(20) = 0
2) P(0) = 0
3) P(10) = 4
4) P(4) = 10
Step-by-step explanation:
We are told that the function P(t) denotes the height of the water in the bath tub.
At P(0) = 0, it means that after 0 minutes, there is no water in the bath tub.
1) If after 20 minutes, the bathtub is empty, then we can depict the function as; P(20) = 0
2) The bath tub starts out with no water. It means at 0 minutes, there was no water in the tub. Thus;
P(0) = 0
3) If after 10 minutes, the height of the water is to be 4 inches, then;
P(10) = 4
4) If the height is 10 inches after 4 minutes, then;
P(4) = 10

For this project, you will research setting up a food cart that sells one item (like hot dogs in buns) along with any condiments (like catsup, mustard, relish, onions, etc.) and necessary serving products (like napkins, plates, containers/wrapping foil, etc.) You may pick any food item of your choice. You will determine your total cost function, revenue function, profit function, and find your break-even point(s).
Variable(s): Very clearly define your variable(s) and be specific. For example, if you say "x
2. Total Cost: Research and determine your total cost function. Your cost function should include the cost of the cart, cost of paying employees, cost of the food and supplies for the cart, etc. Fully explain how you arrived at your cost function. Provide information/links in how you determined what your supplies and materials cost. (You may ignore the cost of permits, taxes, and city fees.)
3. Marginal Cost: Determine your marginal cost function. In your own words, explain what your marginal cost function tells you. How is this different from what your total cost function tells you?
4. Revenue: Determine your revenue function. Explain how you arrived at this function.
5. Profit: Determine your profit function. Explain how you arrived at this function.
For this project, I will choose the food item to be "Gourmet Burgers." Now let's go through each step as outlined.
1. Variable(s):
- x: Number of gourmet burgers sold
2. Total Cost:
The total cost function includes various components:
- Cost of the food ingredients for each gourmet burger
- Cost of the buns, condiments, and other toppings
- Cost of the cart and any necessary equipment
- Cost of paying employees
- Cost of serving products like napkins, plates, and containers
To determine the cost function, I would research the prices of the food ingredients, condiments, buns, and other supplies needed for each gourmet burger. I would also consider the cost of the cart, equipment, and estimated wages for the employees. By summing up all these costs, I can derive the total cost function.
3. Marginal Cost:
The marginal cost function represents the change in total cost when one additional gourmet burger is produced and sold. It can be calculated by taking the derivative of the total cost function with respect to the variable x (number of burgers sold). The marginal cost function provides insights into how the cost per unit changes as the production level increases.
The marginal cost function tells us how much it costs to produce and sell one additional gourmet burger, considering factors like additional ingredients, labor, and supplies required. It helps in making decisions regarding production levels and pricing.
4. Revenue:
The revenue function is determined by multiplying the price per gourmet burger by the number of burgers sold. The price per gourmet burger can be determined based on market research, competition, and desired profit margin. Multiplying this price by the number of burgers sold gives the revenue generated from sales.
5. Profit:
The profit function is obtained by subtracting the total cost function from the revenue function. It represents the financial gain or loss from selling a certain number of gourmet burgers. The profit function helps in assessing the profitability of the food cart business and making decisions related to pricing, cost management, and production levels.
To find the break-even point(s), we set the profit function equal to zero and solve for the number of gourmet burgers sold that result in zero profit. The break-even point is the production level where the revenue equals the total cost, indicating that no profit or loss is incurred.
It's important to note that the specific values and calculations for the cost, revenue, and profit functions would require extensive research, market analysis, and consideration of various factors such as local market conditions, ingredient prices, labor costs, and other operational expenses.

Write the quadratic equation in standard form:
4x2 + 5x + 10 = 2x
The quadratic equation 4x² + 5x + 10 = 2x in standard terms can be written as 4x² + 3x + 10 = 0.
A quadratic equation is of the form ax² + bx + c = 0, where a is the coefficient of x², b is the coefficient of x and c is the constant term. Such equations are called quadratic because the degree of the equation is 2 as the highest power of the polynomial is 2. Such equations have 2 roots, whose sum equals [tex]-\frac{b}{a}[/tex] and their product is equal to [tex]\frac{a}{c}[/tex].
Some examples of quadratic equations are 2x² + 3x - 1, 4x² + 16x + 4, etcectra.
The given quadratic equation is 4x² + 5x + 10 = 2x.
4x² + 5x + 10 = 2x
4x² + 5x - 2x + 10 = 2x - 2x
4x² + 3x + 10 = 0.
Hence, in the standard form, the quadratic equation 4x² + 5x + 10 = 2x can be written as 4x² + 3x + 10 = 0.
