The sound wave for the note a above middle c can be modeled by the function y = 0.001 sin 880 π ø. what is the amplitude of this equation?

a. 0.001
b. 880
c. π
d. 0.88
e. 288.25

Option A

Step-by-step explanation:

The sinusoidal functions have the following form

Where

is the period of the function

A is the amplitude: Half the difference between the minimum value and the maximum value of the function.

In this case the function is:

Therefore the amplitude of this equation is

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
