Answer:
The amplitude is
Step-by-step explanation:
Let f(x) be a sinusoid function that has the following format:
Then b is the amplitude of the function
h is the vertical displacement of the wave
s is the phase angle
is the period.
In this problem
Then
Therefore the amplitude of the function is
The amplitude is a measure of the vertical size of the sinx wave
Answer: C) There is no positive or negative correlation
A positive correlation is one where the values are increasing, and the line of dots are clearly going down to up.
A negative correlation is the opposite. The values are decreasing, and the line goes from up to down.
This correlation is one that is neither positive or negative. It is a straight line where the values neither increase nor decrease.
