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

Hi Sasha! I understand this math is hard,but I'm here to help. 9 goes on top of 14!
If we put 14 on top of 9 it would be an inproper fraction,that's when a fraction is not very easy to work with. Now, we could do 9÷14. :)
Hope dis helps!

Answer:
Figure D
Step-by-step explanation:
we know that
If the scale factor of the dilation is 1/2, that means the dilation is a reduction
so
the answer is between the Figure C and Figure D
but
a rotation of 180° eliminate the Figure C
therefore
The answer is the Figure D
Answer:
The answer is G.
