Answer:
Its b.
Step-by-step explanation:
m < 3 = m < 4 (vertical angles)
m < 1 = m < 5 ( alternate angles)
Therefore the triangles are similar.
The function for the height is

f(0) = 5 cos(0) + 7 = 5 + 7 = 12 (verified)
The period is T = 12 hours.
After 4 hours (t = 4), the height is

A graph of f(t) confirms the answer.
Answer: 4.5 ft
Answer:
The second one would be the answer.
Step-by-step explanation:
If you look at the model, it shows it on 125 going down to 90.
If she has $125 and she spends $35 on gas, you would subtract that from how much money she has.
