Bonus (5 points) The table above shows yearly population of African Black Rhinoceri in thousands. Suppose t is the number of years since 1960 and P is the rhinoceros population in thousands. A student claims that the size of the population is modeled by the equation:
Is this a good mathematical model for the size of the rhinoceros population? Why or why not? (Hint: 0.1 = 1/10.)
