Solve the following. Write your solutions clearly and legible. Answers without solutions will not be considered. 1. The population of a town grows at the rate proportional to the population present at any time t. The initial population of 600 increases by 12% in 10 years. What will be the population in 30 years? 2. Brine containing 3 lb/gal of salt enters a tank at the rate of 4 gal/min and the solution well-stirred leaves at 4 gal/min. The tank initially contains 30 gal of water. What is the amount of salt in the tank after 5 minutes? 3. A resistance of 100 ohms and a capacitance of 0.02 farad is connected in series with a 200 volts battery. Find the charge after 0.5 second and the current after 0.4 second. dy 2y 4. + =4x3 dx X 5. xy'ty = xy+ 6. y" ty = 2t2; y(0) =1, y'(0) =0 (solve using Laplace Transform)
