Find the time it takes for a rocket following the path h(x)= -2x^2+ 18 to hit the ground a. 2 seconds b. 3 seconds c. 8 seconds d. 9 seconds

The time it takes for a rocket  to hit the ground is 3 seconds

Step-by-step explanation:

We are given equation for height as

where

x is the time in seconds

When object hits the ground

then height becomes 0

so, we can set h(x)=0

and then we can solve for x

Subtract both sides by 18

So,

the time it takes for a rocket  to hit the ground is 3 seconds

a is the correct

it could be 1,3 and more others to create a cylinder.
