Answer:
Option 3.
Step-by-step explanation:
The given function is

where, h(t) is the height of a small rock falling from the top of a 124-ft-tall building and t is the time in seconds.
It is a downward parabola.
Equate the function equal to 0, to find the time at which the rock touch the ground.

If
, the according to the quadratic formula

Using quadratic formula, we get



Time cannot be negative. So, the rock remain in the air in the interval 0 < t < 2.
Therefore, the correct option is 3.

Find the zero term:
Plug in 0 for n.
a = 8 + 3(0 - 1)
a = 8 + 3(-1)
a = 8 + (-3)
a = 5
Answer: 5
-------------------------------
Find the first term:
Plug in 1 for n.
a = 8 + 3(1 - 1)
a = 8 + 3(0)
a = 8 + 0
a = 8
Answer: 8
-------------------------------
Find the 40th term:
Plug in 40 for n.
a = 8 + 3(40 - 1)
a = 8 + 3(39)
a = 8 + 117
a = 125
Answer: 125

1/4q = 3w + 3...multiply both sides by 4
q = 4(3w + 3)
q = 12w + 12 <===
