3. [-/1 Points] DETAILS ZILLDIFFEQ9 10.4.010. MY NOTES PRACTICE ANOTHER A predator-prey interaction is described by the Lotka-Volterra model x' -0.15x + 0.025xy y' = 0.25y - 0.025xy. (a) Find the critical point in the first quadrant. (x, v) = ( Use a numerical solver to sketch some population cycles. (Choose x(0) = 9 and y(0) = 5.) 14 14 10 10 20 40 60 100 20 14 12 x(1) 12 x(t) 10 10 160 (b) Estimate the period of the periodic solutions that are close to the critical point in part (a). (Choose x(0) = 9 and y(0) = 5. Use a CAS to estimate the period and round your answer to two decimal places.) Need Help? Read It
