A copper wire has a resistance of 9.00 ohms at 33.0 degrees. Determine the resistance (in ohm) at 433 degrees celsius. The temperature coefficient of resistivity for copper wire is 3.90*10^-3 degrees celsius to the negative one power. (Assume that the temperarure coefficient of resistivity was measured using the reference temperature 20 degrees celsius.)
