You are monitoring the how much pollution is in a reservoir by running off a continuous sample of the reservoir's contents into a monitoring tank. Suppose you have 11} L of pure freshwater in the tank. You open the valves and allow water from the reservoir to ow into the tank at a rate of 5 L per hour and allow it to drain out at the same rate. Suppose the concentration of the pollutant in the reservoir at t hours after the 1values open is given by the function CH) 2 2 + 2sin{:2t} mg 1' L. Construct the differential equation that describes the rate of change of chemical in the monitoring tank. Solve the differential equation and plot the solution curve. How does the form of the function describing the inow concentration aect the behavior of the solution in the tank
