for rhis question are u tryna find m?
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:
-46
Step-by-step explanation:
We need to find the common difference of this arithmetic sequence:

So, the common difference d = -4. We can now write the equation:


So, the 15th term is -46.
