7(b)= with my mind
Answer:
7 he gets 7 becuse he only did 7#43/6/h
Step-by-step explanation:
Step-by-step explanation:
hope it will help you thank you
For this case we have the following equation:
h (t) = - 12t2 + 36t
When the object hits the ground we have:
- 12t2 + 36t = 0
We look for the roots of the polynomial:
t1 = 0
t2 = 3
Therefore, the time it takes the object to hit the ground is:
t = 3 s
Answer:
the time when the object hits the ground is:
t = 3 s
2/3 = 18/27
20/27 > 18/27 ⇒ 20/27 > 2/3
