Answer:
t = 8.69 s
Step-by-step explanation:
The height h of the rocket in feet above the surface of the lake can be modeled by :

Let we need to find the time to reach the ground. When it reach the ground, h = 0

We need to find the value of t.
t = 8.69 s and -2.45 s
Neglecting negative value,
t = 8.69 s
Hence, it will take 8.69 s to reach the ground.

Answer:
85
Step-by-step explanation:
The number you Add with goes up by 2 with each equation. Since five is the first number,
5+3=8 (Pattern #2)
8+5=13 (Pattern #3)
13+7=20 (pattern #4)
20+9=29 (pattern #5)
29+11=40 (pattern #6)
40+13= 53 (pattern #7)
53+15=68 (pattern #8)
68+17=85 (pattern #9)
