Answer:
0.261 ohm
Step-by-step explanation:
If the radius increases by a factor of 0.7/0.4= 7/4, the square of this factor is (7/4)^2 = 49/16. The inverse of this square is 16/49, which is the factor by which the resistance changed.
The resistance of the larger wire is ...
(16/49)(0.80 ohm) ≈ 0.261 ohm
The answer would be 2.5 feet or 2 1/2
Answer:
D (last one)
Step-by-step explanation:
(x - 3)(x + 11)
Expand
x² + 11x - 3x - 33
Simplify
x² + 8x - 33
Answer:
x=1
Step-by-step explanation:
3(x+2) - 4 = 2(x-1) +5
Distribute
3x +6 -4 = 2x -2 +5
Combine like terms
3x +2 = 2x +3
Subtract 2x from each side
3x-2x +2 = 2x-2x+3
x+2 =3
Subtract 2 from each side
x+2-2 = 3-2
x=1
