An initial population of 80 fish is introduced into a lake. This fish population grows according to a continuous exponential growth model. There are 216 fish in the
lake after 11 years.
(a) Letr be the time (in years) since the initial population is introduced,
and let y be the number of fish at time.
Write a formula relating y to f
Use exact expressions to fill in the missing parts of the formula.
Do not use approximations,
(b) How many fish are there 13 years after the initial population is
introduced?
Do not round any intermediate computations, and round your
answer to the nearest whole number.

4 The formula for the Richter rating of a quake is given by R - logQ.
You have a seismograph set up at home and see that there was an event while you
were out that had an intensity of Q = 989. A Richter rating of 4 or more means a
moderate quake occurred. Which of the following is TRUĚ given the situation?
