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

6. 1
You can solve this easily using point slope form: y-y1 = m(x-x1)
Substitute the given y value in for y1 and the given x for x1, and substitute the slope in for m.
To put it in slope intercept form, isolate y.
Hope this helps!
