Answer:
Step-by-step explanation:
From the function, y = cos (3x)
Inputting values of x (horizontal axis), x = pi
y = cos (3 × pi)
= -1 ( remember you are dealing with values in radians not degree)
So now graph 1 and 3 have the same values. So inputting, x = pi/2 into the function, y = cos (3x)
= cos ((3 × pi)/2)
= 0

Answer:
P = 21x + 4
Step-by-step explanation:
The perimeter is the length of all the sides added up.
(3x) + (4x + 1) + (2x - 2) + (2x - 2) + (3x + 1) + (4x + 5) + (3x + 1)
3x + 4x + 1 + 2x - 2 + 2x - 2 + 3x + 1 + 4x + 5 + 3x + 1
21x + 1 - 2 - 2 + 1 + 5 + 1
21x + 4
The equation for the perimeter is
P = 21x + 4
