An electrical heating element produces heat depending on the resistance of the element and the current passed through it. the heat produced can be given by the formula h = i2r where h is the heat generated, i is the current, and r is the resistance. if the element has a fixed current of 2 amps passing through it and a variable current of x amps, it is able to produce a heat of 10x3 + 80, depending on the variable resistance for different additional values of current x. determine the formula for the variable resistance.
