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.

Rachel is using grouping to find the factors of a quadratic expression. She has reached the step shown below. Determine the fact
Feliz [49]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

If the factored form is given by

(3x-4)(x+2)

Then its standard form will be given by

(3x-4)(x+2)\\\\=3x^2+6x-4x+8\\\\=3x^2+2x+8

if factored form is given by

(3x+2)(x+4)

Then its standard form will be given by

(3x+2)(x+4)\\\\=3x^2+12x+2x+8\\\\=3x^2+14x+8

Hence, only first option is correct.
