A 0.8 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 0.3% per second. Express Q as a continuous function of time t in seconds. Use the form given below.

Basically I need to find A(t). Not sure how to do this, any help is appreciated! (Forms to be posted below!)

$$Q(t)= A(t) 0\le t <1 and B(t) 1<t$$
