An initial population of 80 fish is introduced into a leke. 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 to Use exact expressions to fill in the missing parts of the formula Do not use approximations -4 (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. fish 8 CHO x 6 CEBO

6. The initial population of a town was 12000. After 5 years the population increased to 38000 people. /6a 1c a) Express the population growth as an exponential function of time (in years) in the form A = Aoekt.

A vehicle purchased for $25000 depreciates at a constant rate of 4%. Determine the approximate value of the vehicle 15 years after purchase. Round to the nearest whole number.

At the beginning of the last decade, a total of 7.2 million passengers took a cruise vacation. The global cruising industry has been growing at approximately 7% per year. Assume that this growth rate continues. Suppose N = (t) gives the number of passengers, in millions, that take a cruise vacation at year t. Answer parts (a), (b), (c), and (d) of the question. Click VERIFY to move to the next part. (a) Report the following. Use the pull-down menu to indicate the units. A0) = Number Click for List (b) If (t) is written in the form a-b’, do you predict the value of b to be greater than 1 or less than 1? O b is greater than 1 O b is less than 1 (c) Complete the boxes below to write a formula which gives N as a function of t, where t is in years. Do not round any values. Since your formula gives N in millions of people, check that it passes through the initial value x = 0, N= 7.2, as opposed to passing through x = 0, y = 7,200,000. N= Number ( Number (d) How many millions of cruise…
