Answer:
Trampolinist will land on the trampoline after 0.9 seconds.
Step-by-step explanation:
The function h(t) = -16t² + 15 represents the relation between height 'h' above the ground and the time 't' of the trampolinist.
We have to find the time when trampolinist lands on the ground.
That means we have to find the value of 't' when h(t) = 15 - 13 = 2
[Since trampoline is 2 feet above the ground]
When we plug in the value h(t) = 2
2 = -16t² + 15
2 + 16t² = -16t² + 16t² + 15
16t² + 2 = 15
16t² + 2 - 2 = 15 - 2
16t² = 13
t = 
t ≈ 0.9 seconds
Therefore, trampolinist will land on the trampoline at 0.9 seconds.
7 <span> more than 3 times a number </span>

Answer:
haha 4
Step-by-step explanation:
2 + 2 = 4
voila good luck:)
Part A Simplify:
Answer is - 12b + 6c + 18
Part B
Answer is (D)
Factor/simplify
- 12b + 6c + 18
6(- 2b + c + 3)
= (6)(- 2b + c + 3)
= (6)(- 2b ) + (6)(c) + (6)(3)
= - 12b + 6c + 18
therefore,- 12b + 6c + 18; Factored in GCF is 6(-2b + c + 3)
- 12b + 6c + 18
reorder the terms
18 + 12b + 6c
Factor out the GCF " 6"
6(3 + 2b + c)
Final Result:
6(3 + 2b + c)
Hope this helps
It's 12 because if you divide 36 by 3 (consecutive) it equals 12
