The amount of charge that passes through a system is given by Q(t), measured in coulombs. Current is the rate at which the charge flows through the system, and it’s given by I(t), measured in amperes (also known as coulombs per second). If the current is modeled by I(t) = 9t^2+2t+3 for t ≥ 0, how much charge passes through the surface after 8 seconds?
