Let us take a number x
The four consecutive numbers will be
x+1, x+2, x+3
Thus our equation will be
x + x+1 + x+2 + x+3 = 42
4x + 6 = 42
4x = 36
x= 36/4
x= 9
Thus the four numbers are (substitute)
x=9
x+1=9+1=10
x+2=9+2=11
x+3=9+3=12
9,10,11,12
Answer:
V = 6 or V = -6
Step-by-step explanation:
Solve for V over the real numbers:
V^2 = 12^2 - 6 2 9
12^2 + 2 (-6) 9 = 36:
V^2 = 36
Take the square root of both sides:
Answer: V = 6 or V = -6
Answer:
r= RE/I
Step-by-step explanation:
E=I(R+r)
divide both sides by I
E/I = R+r
subtract both sides by R
R(E/I) = r
r = RE/I
