    population question

    The rat population in a major metropolitan city is given by the formula n(t)=63e^0.035t where t is measured in years since 1993 and n(t) is measured in millions.

    What was the rat population in 1993 ?______

    What is the rat population going to be in the year 2008 ? ________

    I'm just plugging the years into t correct?

    by rate they mean they want you to find n'(t) = rn(t)

    you know r = 0.035

    so you have n'(t) = 0.035n(t)

    the questions are asking for n'(0) \mbox { and } n'(15) respectively
