Unformatted text preview: = 1 2 , = 5.) A tank contains 50 kg of salt dissolved in 4000 L of water. Brine that contains 0.05 kg salt per liter of water enters the tank at a rate of 30 L/min. The solution is kept thoroughly mixed and drains from the tank at the same rate. How much salt remains in the tank after 2 hours ? 6.) Find the area Parametric enclosed by the xaxis and the curve: = 1 + , = 2 enclosed by the yaxis and the curve: = 2 2 , = Polar of the region that lies inside the first curve and outside the second curve: = 3 cos , = 1 + cos 7.) Eliminate the parameter to find a Cartesian equation of the curve. = 3 5 , = 2 + 1 8.) Identify the curve by finding a Cartesian equation for the curve. = csc...
