Which statement describes the rate of change of the following function? f(x) = -6x - 7 a. the function has a varying rate of change when x < 7. b. the function has a constant rate of change, decreasing for all x at a rate of 6. c. the function has a varying rate of change when x < 6. d. the function has a constant rate of change, decreasing for all x at a rate of 7.

The correct answer is B. The function has a constant rate of change, decreasing for all x at a rate of 6.

In order to find the rate of change, we have to identify the slope. The slope is always the coefficient of x when in slope intercept form. In this case it is -6, which means it decreases at a rate of 6.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
