The resistance y (in ohms)of 1,000 feet of solid copper wire at 68 degrees Fahrenheit can be approximated by the model

y = \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.

\begin{array} { | l | l | l | l | l | l | } \hline x & 15 & 45 & 55 & 70 & 75 \\\hline y & & & & & \\\hline\end{array}
