Can you put the question In good order so I can answer it for you
I gotchu !! just give me a moment to write it out
Answer:
Step-by-step explanation:Since we want to know how much time elapsed since the object was launched until it ht the ground. At the ground, the height is 0.
Therefore the equation h(t) = 80t – 16t2 becomes 0= 80t – 16t2
Solving the equation for t gives 80t =16t2 or 16t=80 or t=5sec
The object hits the ground 5 seconds after it is launched.
Step-by-step explanation:
The magnitude of x is equal or less than 7.
=> We have |x| <= 7.
