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: z=x+2
Step-by-step explanation:
Answer:
69
Step-by-step explanation:
both edges equal 90 degrees
90 plus 90 plus 111 =291
360-291
28,368 dollars because 1,576 x 18 is 28,368
30 divided by 4 is 7.5, so that as a mixed number could be 7 1/2.
