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.

Answer:

A. y - 3 = -(x + 5)

Step-by-step explanation:

The general formula for point-slope form is:

$y-y_{1} = m(x-x_{1})$ , where 'm' is the slope and $(x_{1},y_{1})$ is a point on the line

Using the given graph, you can see that the line is downhill, indicating a negative slope. Starting at the y-intercept of -2 and going down two and over two to the point (2, -4) tells us the overall slope is '-1'. You can also see that there is a point at (-5, 3) on the graph. Using the slope (-1) and the point (-5, 3):

y - 3 = -1(x + 5)
