- Use a calculator to help solve each problem. Alcohol absorption In one individual, the percent of alcohol absorbed into the bloodstream after drinking two glasses of wine is given by the following formula. Find the percent of alcohol absorbed into the blood after 12 hour. Pt=0.31-e-0.05t where, t is in minutesarrow_forwardPhysiology Doctors treated a patient at an emergency room from 2:00P.M.to7:00P.M.. The patient’s blood oxygen level L (in percent form) during this time period can be modeled by L=0.270t2+3.59t+83.1,2t7 where t represents the time of day, with t=2 corresponding to 2:00P.M.. Use the model to estimate the time (rounded to the nearest hour) when the patient’s blood oxygen level was 93.arrow_forward
