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: A.
Both investments are decreasing in value, and investment A is decreasing in value faster.
Step-by-step explanation:
Answer:
ill take it loll thx u too homie
9/10=180/x
x=200
8/10=180/x
(180*10)/8
(180*5)/4
x= 225
225-200=25
Answer: 25
I THINK
Answer:
x = 7/4 or 1.75 or 1 3/4
