Use the formula d= x2-x1^2+y2-y1^2
X2 would be -3+5 ^2+ 7+1^2
7=y2
1=y1
Now calculate
-3+5=2
2^2 +4^2 Since negative 3 and negative 1 = positive 4
Now square 2 which is for and 4 squared is 16
Add them up and it will be = 20 square which can simplify to 4/5
Answer:
The voltage across resistor is 
Step-by-step explanation:
We are given with Voltage across terminals of a series RL circuit, 
And Resistance R=40Ω
And inductor reactance
Ω
Since Resistor and inductor are in series, same current flows through both.
And that current, I = 

= 
Therefore voltage across resistor,
