Use a graphing device to draw several members of each family on a common screen. x 2 y 2 = k (_) (_) This is a family of ellipses. (_) (_) This is a family of parabolas. (_) (_) This is a family of concentric circles. (_) (_) This is a family of straight lines. (o) (o) This is a family of hyperbolas. 6. [SCalcCC2 7.3.36.] 3/3 points Last Response  Show Details All Responses Notes A tank contains 1000 L of pure water. Brine that contains 0.05 kg of salt per liter of water enters the tank at a rate of 5 L/min. Brine that contains 0.04 kg of salt per liter of water enters the tank at a rate of 10 L/min. The solution is kept thoroughly mixed and drains from the tank at a rate of 15 L/min. (a) How much salt is in the tank after t minutes? (130/3)*(1exp(3*t/200)) (130/3)*(1exp(3*t/200)) kg (b) How much salt is in the tank after 40 minutes? 19.5514 19.6 kg...
