Answer:

D. R(x)=850x+9600

Step-by-step explanation:

Use the given information as points on a line, and find the slope.

The two given points are (10, 18,100) and (20, 26,600).

slope = (difference in y)/(difference in x)

slope = (26,600 - 18,100)/(20 - 10)

slope = 8,500/10

slope = 850

Only choice D. has a slope of 850.

Answer: D. R(x)=850x+9600

Answer:

We are given that the pyramid has a square base that is inscribed in the circular base of a cone.

" To inscribe something means to draw (a figure) within another so that their boundaries touch but do not intersect "

Hence we have to draw a figure such that the  vertices of the square base of pyramid touch the points on the circle which is a base of a circular cone and also the top of the pyramid touches the top of the cone.
