A stone is dropped of a 1296-ft-cliff. The height of the stone above the ground is given by the equation h= - 16t^2+1296, where h is the stone’s height in feet, and t is the time in seconds after the stone is dropped. Find the time required for the stone to hit the ground.
1 answer:
When stone hits the ground, it's height will be zero, and since we're finding the time that's required for the stone to hit the ground, we can set h = 0 and solve for t.

Answer:A
Step-by-step explanation:
we need to first find the answer to the equation.
2x+6=22
6-6=0
22-6=16
2x=16
divide both sides by 2
x=8
A=1/2 b*h
