Answer:
17%
Step-by-step explanation:
to find the percentage of something, you have to fill out the following formula:
x/100 = 21.25/125. Basically that is saying that some percent out of 100 is equal to 21.25 out of 125. To solve that, you have to cross multiply:
125x = 2125
then you have to divide, to single out x:
the answer is 17
so it is 17%
Answer:
Step-by-step explanation:
Let the equation of the cosine function is,
y = Acos(Bx)
From the graph attached,
A = Amplitude = 
= 1
B = 
B = 
B = 
B = 4
Therefore, equation of the cosine wave given in the graph will be,
y = 1.Cos(4x)
y = Cos(4x)
Answer:
