The voltage V across a resistor in an electric circuit is the product of the resistance and the current. If the current I (in A) varies with time t (in s) according to the relation I = 1.00 + 0.071 and the resistance varies with time according to the relation R = 6.00 -0.90t, find the rate of change of the voltage when t = 5.00 s. dV dt =0 (Type an integer or decimal rounded to the nearest thousandth as needed.)
