X=9. Square both sides. Then add 5 to both sides.

A sequence is arithmetic if the difference between consecutive terms is constant.

The fifth term is -8.
Answer:
After t = 4 the rocket will hit the ground.
Step-by-step explanation:
We are given a parametric equation as x = 3t² and y = - 4t + 16.
If we assume that the x is a measure of horizontal distance, y is the measure of vertical distance and t is the time of travel of the rocket, then by making y = 0, we will get the time to hit the ground.
Hence, - 4t + 16 = 0
⇒ t = 4
Therefore, after t = 4 the rocket will hit the ground. (Answer)
