What is the average rate of change of the line whose equation is: y−3=−12(x+4)?

A: −3

B: −4

C: 3

D: −12

Amachine part consists of a half sphere and a cylinder, as shown in the figure. the total volume of the part is π cubic inches.

Given that y varies directly to the square root of (x + 1), and that y = 1 when x = 8,(a)express y in terms of .x,(b)find the value of y when x = 3,(c)find the value of x when y = 5.

What unit of been sure would be appropriate for the volume of a sphere with a radius of 2 meters
