Answer 2

I put A down

Answer 3

B** sorry

Answer 4

You have to put t = 9

Answer 5

If I replace the t with 9, I get 7, but it says 9 hours instead of 12 so you have to take 3/4 of it right?

Answer 6

No when you put t = 9 , you will get 5.

Answer 7

so 4.5 feet

Answer 8

See when I put t = 9, I get,

\(f(9) = 3*\cos{\cfrac{9\pi}{6}} + 5\)

\(\implies f(9) = 3*\cos{\cfrac{3\pi}{2}} + 5\)

\(\implies f(9) = 3*(0) + 5\)

\(\implies f(9) = 5\)

So, B should be the correct answer.

Answer 9
