Answer:
6.5e^(i·(-157.38°)) ≈ 6.5e^(-2.7468i)
Step-by-step explanation:
A suitable calculator can find the value of this ratio for you.
((2+3i)/(1-i))² = -6 -2.5i ≈ 6.5∠-157.38° ≈ 6.5e^(-2.7468i)

Answer:
10%
Step-by-step explanation:
First, 97.90-89=8.90
8.90/89 = x/100
8.90 x 100 = 890
890/89=10%
Check Answer:
89 x 10%=8.90
89+8.90= 97.90
Therefore, the sales tax percentage is 10%
