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.

Can someone help me with this ​
Goryan [66]

If you gimmie brainliest.

It looks like AC is 16.97, given a^2+b^2=c^2.

Honestly it's been a bit since i did something like this.

It looks like cd is something like 30, seeing as that's the height of the box.

17^2+30^2=1189c²

√c is basically 34

The longest rod that can fit is 34 in.

The rod can not fit inside the box, it is 2 inches too long.

Is that good?
