A drug response curve describes the level of medication in the bloodstream after a drug is administered. A surge function S(t)=AtpektS(t)=Atpe-kt (where t>0t>0) is often used to model the response curve, reflecting an initial surge in the drug level and then a more gradual decline. If, for a particular drug, A=0.03A=0.03, p=4p=4, k=0.03k=0.03, and tt is measured in minutes, estimate the times tt corresponding to the inflection points. (Round your answers to two decimal places.)
