ANSWER FAST PLEASE 18 POINTS I REALLY NEED THE HELP!

Rate of change: 2/15, Initial value: 8, Equation: y=2/15x+8

Step-by-step explanation:

To find the rate of change, you find two points on the graph. (0, 8) and (15, 10). Then you plug them into the formula for finding the slope: (y2-y1)(x2/x1)=slope.

10-8/15-0=2/15

To find the initial value, you find the y -intercept, which is (0,8) so the initial value is 8.

For the equation, you already have the slope and y-intercept. So you plug the numbers into the slope-intercept form, y=mx+b, which would be y=2/15x+8.

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.
