A rocket is launched from atop a 50-foot cliff with an initial velocity of 40 feet per second. Find out how long it will take for the rocket to hit the ground (zero). Estimate your answer to the nearest tenth of a second.

x+y=90

x=30-y=x

step-by-step explanation:

if you understand you will get the answer

answer: there are x+184 pages in olivia's book.

step-by-step explanation:
