A 0.6 ml dose of a drug is injected into a patient steadily for one second. At the end of this time, the quantity, Q, of the drug in the body starts to decay exponentially at a continuous rate of 0.2% per second. Express Q as a continuous function of time t in seconds. Use the form given below.

Q(t)= { A(t), 0 ≤ t<1
         { B(t), 1<t
