Unformatted text preview: 1) ,y (0) = 0 . 9. A 1000gallon tank initially contains 200 lbs. of salt dissolved in 600 gallons of water. A brine solution containing 2lbs. of salt per gallon is pumped into the tank at a rate of 3 gal./min. The wellmixed solution is pumped out at a rate of 1 gal./min. How much salt is in the tank when it is full? 10. Express the general solution of t 2 y 00 + ty +4 y = 0 as a linear combination of two realvalued functions, and show that they are linearly independent....
