The voltage of the circuit is 8 + i . Option C
<h3>How to determine the voltage</h3>
From the information given, we have that;
E = IZ
Where;
- E is voltage
- I is current
- Z is resistance
We have that;
I = 3 + 2i
Z = 2 - i
Substitute into the formula
E = IZ
E = ( 3 + 2i) ( 2 - i)
Making the product of complex numbers we have:
E = ( 3 × 2 - i ) + ( 4i - 2i²)
E = ( 6 - 3i ) + ( 4i - 2 ( -1) )
E = ( 6 + 2) + ( 4 - 3 ) i
E = 8 + i
Thus, the voltage of the circuit is 8 + i . Option C

It would be: 561000 - 438000 / 438000 * 100
= 12300 / 438000 * 100
= 1230000 / 438000
= 28.08
So, your final answer is 28.08%
Hope this helps!
Answer: The answer would be 15.
Step-by-step explanation: The is because 15 is the Least Common multiple of each number. Ex. 3,6,9,12,(15) 5,10,(15)
Think of it as 20 out of 100
20/100 is 20% and 0.2. Just like 2/10 is 20% and 0.2.
