The height at time t is
h(t) = 144 - 16t²
When t = 0, then h = 144.
Therefore the height from the ground is 144 when the object is dropped.
When the object reaches the ground, h = 0.
Therefore
144 - 16t² = 0
t² = 144/16 = 9
t = 3 s
Answer:
The object reaches the ground in 3 seconds.
Answer:
the first girl
Step-by-step explanation:
because the first girl to take the survey is a sample but the rest that follows are just extras(can i get brainliest pls)

For A put 160 (division sign} 4.
For B put -40
