Copper Wire The resistance y in ohms of 1000 feet of solid copper wire at 77°F can be approximated by the model
where x is the diameter of the wire in mils (0.001 in.). Use a graphing utility to graph the model. By about what factor is the resistance changed when the diameter of the wire is doubled?
