Step-byErosion-step explanation:
H(t) = -16t² + 144
When will the object hit the ground? This means that the height will equal to 0.
h(t) = 0
0 = -16t² + 144
16t² = 144
t² = 144/16
t² = 9
√t² = √9
t = 3
The object will hit the ground after 3 seconds.

Answer:
t ≥ 1.5
Step-by-step explanation:
Lets take time for practicing the piano to be t
The number of hours to practice per week should be at least 6 hours
This is written as t ≥ 6
She already practiced 3 hours this week, thus the remaining hours to practice should be
t ≥ 3
The minimum remaining hours to practice for the remaining 2 days should be
t=3
If these hours are evenly divided, then in a single day she should practice
for t ≥ 1.5
