There are initially 500 rabbits (x) and 200 foxes (y) on Farmer Oats property near Ria, Jofostan. Use Polymath or MATLAB to plot the concentration of foxes and rabbits as a function of time for a period of up to 500 days. The predatorprey relationships are given by the following set of coupled ordinary differential equations: dx/dt= k1x-k2x. Y dy/dt= k3x. Y-k4y Constant for growth of rabbits k1 = 0. 02 Constant for death of rabbits k2 = 0. 00004/(day no. Of foxes) Constant for growth of foxes after eating rabbits k3 = 0. 0004/(day no. Of rabbits) Constant for death of foxes k4 = 0. 04 What do your results look like for the case of k3 = 0. 00004/(day no. Of rabbits) and tfinal = 800 days? Also, plot the number of foxes versus the number of rabbits. Explain why the curves look

raw sugar cane is taken into a process to create sugar, which is essentially sucrose. the raw cane is approximately 16% sucrose, 63% water, and the rest fiber by mass. juice from the cane is extracted by passing the cane through a series of crushers. about 5% extra mass of water is added to the sugar cane prior to this step to help in the extraction process. the crushed cane and liquid juice is sent to a filter press that creates a cake that contains 4% of the weight of the cane juice, which has a composition similar to the overall non-fiber content of the raw cane. the filtrate is sent to an evaporator where enough water is evaporated to obtain a pale yellow juice that is 41% water. a
