8. Bob takes a "drug". The equation of the concentration C(t] in ngj'ml as a function of as a function of time t in hours satisfies the differential equation E = 106-02\" 0.20.

Using your graph from a), find approximately the time interval when Bob will be time interval when Bob will be under the "effects" of the "drug". c) Verify that C(t) = 10te-0.2t is the solution of this differential equation passing through the point C(0) = 0
