13. -12 points SCalcET8 3.4.082. My Notes A model for the length of daylight (in hours) in Philadelphia on the tth day of the year is L(t)-12 + 2.8 sin (t-80) 365 Use this model to compare how the number of hours of daylight is increasing in Philadelphia on March 21 and April 21. (Assume there are 365 days in a year. Round your answers to four decimal places.) March 21 L'(t) April 21 L"(t) = Need Help?Read It Talk to Tutor 14. SCalcET8 3.4085. My Notes -/2 points The average blood alcohol concentration (BAC) of eight male subjects was measured after consumption of 15 mL of ethanol (corresponding to one alcoholid drink). The resulting data were modeled by the concentration function E(t) = 0.0225te-00467t where t is measured in minutes after consumption and C is measured in mg/mL. (Round your answers to five decimal places.) (a) How rapidly was the BAC increasing after 7 minutes? (mg/mL)/min (b) How rapidly was it decreasing half an hour later (t = 30)? (mg/mL)/min Need Help?
