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
There's really no way to write this equation as a word problem .
Answer:
B. 28 degrees
Step-by-step explanation:
ok so,
the starting temperature is 35 degrees then the temperature dropped 4 degrees. making the temp 31 degrees. next the temperature rose 2 degrees, making it 33 degrees. lastly, the temperature dropped another 5 degrees making it 28 degrees out on wednesday.
so the number line showing this would be B.
Answer:
the answer is: 
Step-by-step explanation:
We get the answer using Pitagoras.
so
You just have to make equal fractions, so if c = 4 that means 
= 
so cross multiply to get 7a = 20; divide both sides by 7 to get a = 2.86 and do the same with the other ones
If c = 11 then = 
cross multiply to get 7a = 55; divide both sides by 7 to get a = 7.86 and so on
The answer is true to the other question
Hope this helps :)
