after t seconds,
Q(t) = 9*0.996^t
Now just solve for what you need.
A 0.9 ml dose of a drug is injected into a patient steadily for half a 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 0.4% per second. Using formulas, express Q as a continuous function of time, t in seconds.
For 0 less than or equal to t which is less than or equal to 0.5
And for 0.5 < t
Q=
Q=
