The polynomial given by 1.6t^ 2 - 28t + 200 calculates the heart rate, where t represents the elapsed time in minutes since exercise stopped.
1. What is the heart rate when the athlete first stops exercising?
2. What is the heart rate after 5 minutes?
3. Describe what happens to the heart rate after exercise stops.

I will assume that you have a typo and you meant
- 1.6t^2 - 28t + 200
since it would only decrease for the first 8 or 9 minutes, after that the heart rate would actually increase. This makes no sense.
