Can someone please help with my Quadratic Functions homework in Math?

Question

NASA launches a rocket at t=0 seconds. Its height, in meters above sea level, as a function of time is given by h(t) = −4.9t^2 + 241t + 402 Assuming that the rocket will splash down into the ocean, at what time does splashdown occur?

1. The rocket splashes down after________seconds.

2. How high above sea level does the rocket get at its peak? The rocket peaks at_________ meters above sea level.

Answer 1

1) 0 = -4.9t² + 241t + 402, sovle for t and answer.

2) maximum at t = -241 / 2(-4.9)
