An experimental electrical system has a voltage that can be modeled by V(t) = 0.4t^3 + 6.4t^2 + 6t, where t represents time in seconds. The resistance in the system also varies and can be modeled by R(t) = t + 1. The current I is related to voltage and resistance by the equation I = V/R. Write an expression that represents the current in the system. The expression that represents the current in the system is:
