) If the average cost function for a company is given by C(x) = 0.2x + 20x −1 + 75, nd what level of production produces the low
Stells [14]

Answer:

The correct answer is 10 for lowest average cost and the cost function is 0.2x^{2} + 75x + 20.

Step-by-step explanation:

Average cost function is given by = \frac{Cost}{Quantity} = C(x) = 0.2x + \frac{20}{x} +75.

For minimizing we need to find \frac{d}{dx}C(x) = 0.

⇒ \frac{d}{dx}C(x) = 0.2 - \frac{20}{x^{2}}.

⇒ \frac{20}{x^{2}} = 0.2

⇒ x^{2} = 100.

⇒ x = ±10

⇒ x = 10 ; cost cannot be negative.

Second order derivative is positive which implies the average cost minimizes.

Original cost function is given by C(x) × x = 0.2x^{2} + 75x + 20.

Write an equation of the line that passes through the given point and is parallel to the given line.
Elza [17]

Step-by-step explanation:

y = 5x - 3 is in slope-intercept form.

The slope of this given line is 5,

=> Parallel line will also have slope 5.

We have y = 5x + c, where c is a constant.

When x = 4, y = 7.

=> (7) = 5(4) + c, c = -13.

Therefore the answer is y = 5x - 13.
