Adrug response curvedescribes the level of medication in the bloodstream after a drug is administered. A surge functionS(t) =At^pe^kt

(wheret> 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=0.02,p=4,k=0.09,andtis measured in minutes, estimate the timestcorresponding to the inflection points. (Round your answers to two decimal places.) Give both the x and y coordinates.
