1 8 A tank contains 140 gallons of water and 10 oz of salt. Water containing a salt concentration of (1+sint) oz/gal flows into the tank at a rate of 2 gal/min, and the mixture in the tank flows out at the same rate. The long-time behavior of the solution is an oscillation about a certain constant level. What is this level? What is the amplitude of the oscillation? Round the values to two decimal places. Oscillation about a level = 27.99 Amplitude of the oscillation = 07. Click if you would like to Show Work for this question: Open Show Work
