(0, -8) (option A)
Explanation:Converting from polar to rectangular coordinates (x, y):
polar coordinates (8, 3/2 pi) = (8, 3π/2)
where r = 8
θ = 3/2 pi
x = rcosθ
y = rsinθ
y = 8 sin(3π/2) = 8(sin270)
y = 8(-1)
y = -8
x = 8 cos(3π/2) = 8(cos 270)
x = 8(0)
x = 0
The rectangular coordinates (x, y) = (0, -8) (option A)
