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
35.001 is the closest of the 5 to 35.
Answer:
S(6, 10)
Step-by-step explanation:
1. The Midpoint (in this case, M) will always be halfway between both R and S (or other characters in some cases).
2. As M is only one X value away from R, it is only 1 X value from S as well, but in the other direction.
3. (7, 10) - (1, 0) = (6, 10)
The (7, 10) is the Midpoint Coordinates.
The (1, 0) is the distance from M to R.
The (6, 10) is the coordinates of S.
The amplitude of this function is 4/5. Be sure you understand why that is so.
