Take into account, that in general, a cosine function of amplitude A, period T and vertical translation b, can be written as follow:

In the given case, you have:
A = 4
T = 3π/4
b = -3
By replacing you obtain:

Hence, the answer is:
f(x) = 4cos(8/3 x) - 3

Given:
A rectangular piece of cloth (dimensions):
L = length of the rectangle
W = width of the rectangle
The area of the rectangle is:
A = L x W
If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:
A (one sail) = 1/2 (L x W) <span />
So singlehandedly, November has 25% of the total rain in one year of New York's, which is 62.51 inches.
So, November receives: *percentage* x *total*
= 25% x 62.51 = 15.6275 in
------------------------------------------------------------------------------------------------------
So, in November, New Yorks receives 25% of total rain in one year, which is 15.6275 inches.

Answer:
A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1.
