Question 1042241: I have no idea where to start or what I am doing at all.
The function P(t) = 145e-0.092t models a runner’s pulse, P(t), in beats per minute, t minutes after a race, where 0 ≤ t ≤15. Graph the function using a graphing utility. TRACE along the graph and determine after how many minutes the runner’s pulse will be 70 beats per minute. Round to the nearest tenth of a minute. Verify your observation algebraically.

Here's the plot:
From the plot, I would guess that , after about minutes after the race.

Solving for ,
Take the natural log of both sides ( rounded off )
