HAVE A GOOD DAY!
Total impedance of circuit is Z1 + Z2
Here it is important that real numbers we sum with real numbers and complex numbers with complex numbers
Let Zs represent total impedance.
Zs = Z1 + Z2 = 3 + 4i + 5 - 2i = 3 + 5 + 4i - 2i = 8 + 2i
Answer is :
8+2i
Answer:
The total cost is 130
Step-by-step explanation:
Jumpers: 45 x 2= 90
90-33.33%=$60
Jeans:
50 x 2=100
100-30%=70
Add together
70+60=130
