Suppose the total revenue function is tr = 75q - 4q2 and the total cost function is tc = q2 + 5q + 36.

solniwko [45]

Marginal Revenue is defined as the revenue generated with respect to increase in sale of another extra unit of product.

So we will calculate Marginal Revenue equation by finding the change in Revenue with respect to change in Quantity.

Given the Total Revenue Function as:-

$Tr = 75q-4q^{2}$

Differentiating Total Revenue function (Tr) with respect to quantity (q):-

$\frac{dTr}{dq} = 75-2(4q) = 75-8q$

So Marginal Revenue equation will be, $Mr = 75-8q$

In a regular polygon, the measure of an interior angle is 6.5 times the measure of an exterior angle. How many sides does the po

cestrela7 [59]

Answer:

15 sides

Step-by-step explanation:

Always the sum of interior angle and exterior angle = 180

Let the exterior angle = x

Interior angle = 6.5 *x = 6.5x

x + 6.5x = 180

7.5x = 180

x = 180/7.5

x = 24

Exterior angle = 24°

Sum of exterior angles of any polygon = 360

number of side = Sum of exterior angles ÷ measure of each exterior angle

= 360 ÷ 24

= 15
