The function P(t)=145e0.092tP(t)=145 e^{-0.092 t} models a runner's pulse, P(t)P(t), in beats per minute, tt minutes after a race, where 0t150 \leq t \leq 15. Graph the function using a graphing utility. TRACE\boxed{\text{TRACE}} along the graph and determine after how many minutes the runner's pulse will be 7070 beats per minute. Round to the nearest tenth of a minute. Verify your observation algebraically.
