Nitrogen-13 is a radioactive isotope of nitrogen used in a
physiological test called positron emission tomograph (PET). A typical PET
scan begins with 6.9 picograms of nitrogen-13 (1 picogram grams).
The number N of picograms of nitrogen-13 remaining after t minutes can be
modeled by N = 6.9e-0.06951. How many picograms of nitrogen-13 remain after
10 minutes?
