7. (9pts) A linear model for the population of cheetahs and gazelles in Namibia is given by the following pair of equations:
0.3 Ck + 0.4 Ck = Ck+1 —pCk + 1.3Gk = where Ck measures the number of cheetahs present in a certain Namibian game reserve at time k, Ck gives the number of gazelles (measured in tens), and k is measured in months. (a) Find a value for p (to three decimal places) that guarantees a steady-state outcome for this model, then determine the number of cheetahs present for every 1000 gazelles in the long-run. (b) Find a value for p (to three decimal places) that will guarantee 2% growth in both populations. (c) What must be true about the eigenvalue.s of the transition matrix if both populations die out in the
