A tank initially contains 80gal of pure water. Brine containing 2lb of salt per gallon enters the tank at 2gal/min, and the (perfectly mixed) solution leaves the tank at 3 gal/min. Thus the tank is empty after exactly 80 min.
(A) Find the amount of salt in the tank after t minutes.
(b) What is the maximum amount of salt ever in the tank?

Consider the solution of the differential equation y′=−3yy′=−3y passing through y(0)=0.5y(0)=0.5.
A. Sketch the slope field for this differential equation, and sketch the solution passing through the point (0,0.5).
B. Use Euler's method with step size Δx=0.2Δx=0.2 to estimate the solution at x=0.2,0.4,…,1x=0.2,0.4,…,1, using these to fill in the following table. (Be sure not to round your answers at each step!)
x=x= | 0 | 0.2 | 0.4 | 0.6 | 0.8 | 1.0 |
y≈y≈ | 0.5 |
C. Plot your estimated solution on your slope field. Compare the solution and the slope field. Is the estimated solution an over or under estimate for the actual solution?
A. over
B. under
D. Check that y=0.5e−3xy=0.5e−3x is a solution to y′=−3yy′=−3y with y(0)=0.5y(0)=0.5.
