Answer:

p'(x) = -0.12x +7.7

Step-by-step explanation:

Profit is the difference between revenue and cost:

p(x) = r(x) -c(x)

p(x) = (-0.06x^2 +8x) -(0.3x +240) = -0.06x^2 +7.7x -240

Marginal profit is the derivative of this function:

p'(x) = -0.12x +7.7

The question provides one endpoint and then the midpoint. The midpoint on the coordinate grid is (0, -7) and one endpoint is (-2,-6).

The formula for calculting the midpoint is given as follows;

$\begin{gathered} M=\frac{x1+x2}{2},\frac{y1+y2}{2} \\ Take\text{ the x coordinates and y coordinates one after the other,} \\ 0,7=\frac{-2+x2}{2},\frac{-6+y2}{2} \\ \text{The x coordinates and the midpoint coordinate are} \\ 0=\frac{-2+x2}{2} \\ \text{Cross multiply and you have;} \\ 0=-2+x2 \\ 2=x2 \\ \text{The y coordinates and the midpoint coordinates are;} \\ 7=\frac{-6+y2}{2} \\ \text{Cross multiply and you have;} \\ 14=-6+y2 \\ 14+6=y2 \\ 20=y2 \\ \text{Therefore, the coordinates for the other midpoint is derived as;} \\ (2,20) \end{gathered}$

Therefore, the coordinates of B is calculated as (2, 20)
