The inverse demand function is P = 2400 + 5Q

Given that

Q = 480 - 0.2P

We simply make P the subject of the formula

So, we have

0.2P = 480 - Q

Divide by 0.2

P = 2400 + 5Q

To find the marginal revenue function, we can use the inverse demand function P = 2400 + 5Q, and take the derivative of this function with respect to Q.

The derivative of P with respect to Q is dP/dQ = 5. This represents the change in price for a one unit change in the quantity of operations performed.

So the Marginal Revenue function is MR = dP/dQ * Q = 5Q

To maximize profit, the doctor should equate marginal revenue to marginal cost, which is

MC = dAVC/dQ

So, we have

MC = d(2Q² - 15Q + 400)/dQ

Evaluate

MC = 4Q - 15.

So, we have

5Q = 4Q - 15

Q = -15

Take the absolute value

Q = 15

So, the number of operations is 15

We have

P = 2400 + 5Q

This gives

P = 2400 + 5 * 15

Evaluate

P = 2475

To find the profit, we need to subtract the total cost from the total revenue.

The total revenue is found by multiplying the price by the quantity of operations performed: TR = P * Q = 2475 * 15 = 37125

The total variable cost is found by multiplying the average variable cost by the quantity of operations performed: TVC = AVC * Q = (2Q^2 - 15Q + 400) * Q = 2Q^3 - 15Q^2 + 400Q

The total fixed cost is the fixed cost that doesn't change regardless of the level of output : TFC = $8000

The total cost is the sum of the total variable cost and total fixed cost: TC = TVC + TFC = 2Q^3 - 15Q^2 + 400Q + $8000

The profit is the difference between total revenue and total cost:

π = TR - TC = 37125 - (2Q^3 - 15Q^2 + 400Q + $8000)

When Q = 15,

profit is π = 37125 - (2(15)^3 - 15(15)^2 + 400(15) + $8000)

= 19750

The total profit of F_1 in the week was $25920 and the total profit of F_2 in the week was $0.

The profit vector can be expressed as p = [35 62 30]. The total profit of F_1 and F_2 can be calculated by multiplying the matrix A by the vector p. The result, Ap, is a vector whose components give the total profits of the two stores in the week.

For example, the total profit of F_1 can be calculated as Ap_1 = [35 62 30] * [400 60 240] = [14000 3720 7200] = 25920.

Similarly, the total profit of F_2 can be calculated as Ap_2 = [35 62 30] * [0 0 0] = [0 0 0] = 0.

Therefore, the total profit of F_1 in the week was $25920 and the total profit of F_2 in the week was $0.

When opposite sides of a quadrilateral is equal then the quadrilateral is Parallelogram. (PA = RT and PT = AR)

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

A quadrilateral is a specific type of polygon known as a parallelogram if it contains two parallel opposed sides. A parallelogram has the following qualities:

Each coordinate of the Parallelogram :

P (-3, 0) , A(3, -1) , R ( 2, -5) and T(-4, -4)

Length of PA = √((3 + 3)² + (-1 - 0)²) = √(36 + 1) = √37

Lenght of TR = √((-4 - 2)² + (-4 + 5)²) = √(36 + 1) = √37

Length of PT = √((-3 + 4)² + (0 + 4)²) = √(16 + 1) = √17

Length of AR = √((3-2)² + (-1 + 5)²) = √(16 + 1) = √17

Here, PA = RT and PT = AR ,

so when opposite sides of a quadrilateral is equal then the quadrilateral is Parallelogram.

The expansion of 1/4(x - 12) is x/4 - 3

In order to expand and simplify an expression, we need to multiply out the parentheses and then simplify the resulting expression by collecting the like terms. Expanding brackets (or multiplying out) is the process by which we remove parentheses. It is the reverse process of factorisation.

For example 4(3-y) can be expanded by multiplying the factor 4 by 3 and y = 12- 4y

Similarly the expression 1/4(x - 12) can be expanded by firstly multiply the factor ¼ by x and 12

therefore 1/4(x - 12) = 1/4×x -12×1/4

= x/4 - 3

Therefore the expansion of 1/4(x - 12) is x/4 -3

Answer:

  (3n +8) -3n = 8

Step-by-step explanation:

You have the difference (3n+15) -7, and you want its value when it is decreased by the triple of the original number (n).

The phrase "triple the original number" will be translated to 3n. This is the value you want to subtract.

  (3n +15) -7 = 3n +8 . . . . . "the difference"

  (3n +8) -3n = 8 . . . . . . . . "decreased by triple the original number"

This simplifies to 8, which is the point of the exercise: showing the sequence of steps always gives a value of 8.

You will need 280 cups of cranberry juice and 56 cups of Sprite to make 56 cups of the famous punch.

What is the ratio definition?

A ratio is a mathematical comparison of two or more values or quantities. It is usually written as a fraction, with the first value or quantity being the numerator and the second value or quantity being the denominator.

To make 56 cups of famous punch using the ratio of 5 cups of cranberry juice to 2 cups of Sprite, you can use the following method:

Write the ratio of cranberry juice to Sprite as a fraction: 5 cups cranberry juice / 2 cups sprite

Multiply the fraction by the desired number of cups of punch: (5 cups cranberry juice / 2 cups sprite) x 56 cups punch

Simplify the equation by cross-multiplying: 5 cups cranberry juice x 56 cups punch = 2 cups sprite x 56 cups punch

Solve for the number of cups of cranberry juice: 5 cups cranberry juice x 56 cups punch = 280 cups of cranberry juice

To find the amount of Sprite use the ratio 5:2, meaning you have to use 2 cups of sprite for every 5 cups of cranberry juice. So use 280/5*2 = 56 cups of sprite

When working with word problems, students should first read the problem and decide if it is a one-step or two-step problem.

A one-step problem involves solving for a single unknown quantity, such as finding the total cost of 10 pencils at $0.50 each. The formula for this would be C = Pn, where C is the cost, P is the price, and n is the number of items. To solve this problem, the student would multiply the price and number of items, so C = 0.50 x 10 = $5.00. A two-step problem involves solving for two unknowns, such as finding the total cost of 10 pencils at a 10% discount. The formula for this would be C = Pn (1 - r), where r is the discount rate. To solve this problem, the student would first calculate the discount by multiplying the price and number of items by the discount rate, so C = 0.50 x 10 x 0.10 = $0.50. Then the student would subtract the discount from the total cost, so C = 0.50 x 10 - 0.50 = $4.50.

The value of the variable x for the given f(x) = 2 by simplifying the antiderivative of  the given function is given by x = 0.4865.

Given anti derivative of f(x)  :

For the limit 0 to x for the integration of e^4t with respect t

= [tex]\int\limits^x_0 {e^{4t} } \, dt[/tex]

= ( 1/4) e^4x  + ( 1/4 )

Value of the function f (x)  = 2

Now f(x) = 2

Substitute the value of the function f(x) we get,

( 1/4) e^4x  + ( 1/4 ) = 2

⇒ e^4x + 1 = 8

⇒ e^4x = 7

⇒x = log7 / 4

⇒ x= 0.4865

Therefore, the value of the x by simplifying the antiderivative function f(x) for the given f(x) = 2 is equal to 0.4865.

What is called the mean?

The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. It is sometimes referred to as the "average" and is the most widely used central tendency metric.

Simply dividing the total number of values in a data set by the sum of all of the values yields it. The calculation can be performed on unprocessed data or data that has been combined into a frequency table.

By dividing the sum of the given numbers by the entire number of numbers, the mean—the average of the given numbers—is determined.

Mean: The "average" number; found by adding all data points and dividing by the number of data points. Example: The mean of 4, 1, and 7 is ( 4 + 1 + 7 ) / 3 = 12 / 3 = 4 (4+1+7)/3 = 12/3 = 4 (4+1+7)/3=12/3=4left parenthesis, 4, plus, 1, plus, 7, right parenthesis, slash, 3, equals, 12, slash, 3, equals, 4.
