Question

A 0.2 ml dose of a drug is injected into a patient steadily for 0.75 seconds. 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 percent per second. Using formulas, express Q as a continuous function of time,t, in seconds.
Q(t)=_______ if 0 is less than t less than 0.75 and Q(t)=________ if 0.75 less than t less than infinity.
