Convert z = 9cos200° + 9isin200° from polar form to rectangular form. -8.46 - 3.08i -2.09 – 6.84i 8.46 + 3.08i 2.09 + 6.84i

step-by-step explanation:

what is the figure? attach a picture.

answer: c

substitute in the values.

for a:

f(0) = 0 + 9

f(0) = 9

a is a solution.

for b:

f(7) = 14 + 9

f(7) = 23

b is a solution.

for c:

f (3) = 6 + 9

f(3) = 15

c is not a solution. it's supposed to be 14.

for d:

f(2) = 4 + 9

f(2)= 13

d is a solution.
