<span>What is 2/1 divided by 1 6/7?
</span>answer would be 0.9
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:
Sophia now has 39 cents.
Step-by-step explanation:
One quarter = 25 cents
