Exercises 9-14 refer to the predator-prey and the modified predator-prey systems discussed in the text (repeated here for convenience):
(i)
(ii)
11. Suppose the predators discover a second, unlimited source of food, but they still prefer to cat prey when they can catch them. How would you modify these systems to include this assumption?

With reference to a particular coordinate system in which distance is measured in metres, the position of A at time t (in minutes) is (2t − 1, 3t + 3), and the position of B is (5t − 2, 2t + 5). Let d be the distance between A and B at time t. Show that an expression for d 2 in terms of t is given by d 2 = 10t 2 − 10t + 5.arrow_forwardJim's Camera shop sells two high-end cameras, the Sky Eagle and Horizon. The demands for these two cameras are as follows: D = demand for the Sky Eagle, Ps is the selling price of the Sky Eagle, D is the demand for the Horizon, and PH is the selling price of the Horizon. Ds = 223 -0.60PS +/0.35PH DH = 273 +0.10PS - 0.64PH The store wishes to determine the selling price that maximizes revenue for these two products. Develop the revenue function for these two models.
