Step-by-step explanation:
When the rocket hits the ground, its height ( <em>y</em> ) will be zero. This means we can write the equation as:
- 0 = -16x²+129x+119
So we need to <u>solve that equation</u>:
- a = -16
- b = 129
- c = 119
- x =
x₁ = -0.84
x₂ = 8.90
We discard x₁, as it is negative.
So the answer is x₂, 8.90 seconds.
