The resistance y in ohms of 1000 feet of solid metal wire at  can be approximated by the model  where x is
the diameter of the wire in mils (0.001 in). If the diameter of the wire is doubled, the
resistance is changed by approximately what factor? In determining your answer, you can ignore the
constant –0.46.
