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
point slope form is y-y1=m(x-x1)
from (6,1) y1 = 1 and x1 = 6
slope is given as -3
so you should have y=1 =-3(x-6)
Answer:
Step-by-step explanation:
21 x 0.07= 1.47
21+1.47=22.47
Total=22.47
