(r, theta)= (8, 3/2 pi)
r=(x^2 +y^2)^(1/2)
theta= 3/2 pi
x= r(costheta)
y=r(sintheta)
x=8(cos(3/2 pi))
y=8(sin(3/2 pi))
x=8(0)
y=8(-1)
x=0
y=-8
r=((-8)^2+(0)^2)^(1/2)
r=(64+0)^(1/2)
r=8
rectangular coordinates= (0,-8)
The sin graph starts at zero,

Answer:
y=(3x+2)-2
Step-by-step explanation:
In adding a 2 in the parentheses you are really subtracting a negative number. y= (x-h) + k. The h is responsible for horizontal translations. Therefore, a negative negative two, which is a positive 2, will yield the correct answer.
