Question 11: '7. (7 points) The population of fish in Fisher's Pond grow at a steady rate annually, but shing is so popular that, without restocking, the population would die out. Therefore Fisher's Pond is restocked with fish each spring. Using historical data, we de Clare that DTDS modeling the population of sh, with 2:; representing the average number of fish per m2 of surface area in year t, is given by 17154.1 = 0.737; + 4.8. (8.) Find the xed point 13* of this DTDS. (b) Suppose that in year zero there were 36 sh/m2. Give the general solution formula to this DTDS. ((2) Determine the (whole) number of years necessary until the number of sh per 7212 is within 0.5 of the fixed point, that is, until [wt :r:*|
