Answer: 
Step-by-step explanation:

Plug in your values.

Square 1ft.

Plug this into a calculator or do it manually.

85 is composite because it can be divided by 5 and 17
sqrt(200) ≈ 14.14213562373095
14 = 14
14/3 ≈ 4.666666666666667
From least-to-greatest:
14/3, 14, sqrt(200)

Let's analyse the function

The amplitude is A, so we want A=1.5
Now, we start at x=0, and we have 
After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be 
So, we have

so, the function is
