62= 12+c

Which your answer is 50 cause if you take 62 and subtract it to 12 it's 50. So 50 + 12 = 62

2) f(x) = x² **<br> g(x)= 3x – 2<br> Find f(g(-4)

Usimov [2.4K]

Answer:

$f(g( - 4)) = 196$

Step-by-step explanation:

The functions are;

$f(x) = {x}^{2}$

and

$g(x) = 3x - 2$

We want to find

$f(g( - 4))$

First we find g(-4) to get:

$g( - 4) = 3 \times - 4 - 2$

$g( - 4) = - 12- 2$

$g( - 4) = - 14$

Now

$f(g( - 4)) = f( - 14)$

This implies that,

$f(g( - 4)) = {( - 14)}^{2}$

$f(g( - 4)) = {( - 14)} \times - 14$

$f(g( - 4)) = 196$

The cost, in dollars, of producing x belts is given by Upper C (x )equals 970 plus 12 x minus 0.076 x squared. The revenue, i

umka21 [38]

Answer:

$68.44 for each additional belt

Step-by-step explanation:

The cost and revenue functions are:

$C(x) = 970+12x - 0.076x^2\\R(x) =43x^{\frac{3}{4}}$

The profit function, P(x), is given by subtracting the cost function from the revenue function.

$P(x) = R(x) - C(x)\\P(x)=43x^{\frac{3}{4}}+0.076x^2-12x-970\\$

The derivate of the profit function gives us the rate at which profit changes:

$\frac{dP(x)}{dx} =P'(x)=32.25x^{\frac{-1}{4}}+0.152x-12\\$

For x = 484, the rate of change is:

$P'(484)=32.25*484^{\frac{-1}{4}}+0.152*484-12\\P'(484) = \$68.44/belt$

Profit is increasing by $68.44 for each additional belt
