Solved

The Resistance Y (In Ohms)of 1,000 Feet of Solid Copper y=10,770x20.37,5x100y = \frac { 10,770 } { x ^ { 2 } } - 0.37 , \quad 5 \leq x \leq 100

Question 37

Multiple Choice

The resistance y (in ohms) of 1,000 feet of solid copper wire at 68 degrees Fahrenheit can be approximated by the model y=10,770x20.37,5x100y = \frac { 10,770 } { x ^ { 2 } } - 0.37 , \quad 5 \leq x \leq 100 where x is the diameter of the wire in mils (0.001 inch) . Complete the table.
