When two rays are put together it forms an angle (because of the three points)
myrzilka [38]3 years ago

Sample Response: An angle is defined as two rays with a common endpoint, so CAB (or BAC) is an angle. A line is described as an infinite set of points that extend forever in either direction, which these rays also do.

Find the maximum profit and the number of units that must be produced and sold in order to yield the maximum profit. Assume that
Murljashka [212]

Answer:

185 units

Step-by-step explanation:

Given,

The revenue function is,

R(x) = 4x

Cost function,

C(x) = 0.01x^2 + 0.3x + 4,

Where,

x = number of units produced.

Thus, profit = revenue - cost

P(x) = 4x - ( 0.01x^2 + 0.3x + 4) = -0.01x^2 + 3.7x - 4

Differentiating with respect to x,

P'(x) = -0.02x + 3.7

Again differentiating with respect to x,

P''(x) = -0.02

For maxima or minima,

P'(x) = 0,

-0.02x + 3.7x =0

-0.02x = -3.7

\implies x = \frac{3.7}{0.02}=185

For x = 185,

P''(x) = negative,

Hence, for maximising the profit 185 units must be produced.
