The number of fish per square kilometer in a lake is determined by the DTDS 40.33% a: : H1 200 + 0th ' where t is the time in years since the beginning of the observation. (3) (1 point Mobius) Suppose in year 9 we recorded 1, 100 fish per square kilometer. How many fish per square kilometer were there the year before, in year 8 ? Give your answer with an accuracy of two decimal places. Answer: 938 : (b) (1 point Mobius) What is the updating function of this DTDS ? (Careful about parentheses!) a 2 :m (c) (2 points Mobius) Determine the two fixed points (equilibria) of this DTDS. Enter the two equilibria 191
