Set up an initial value problem that represents the situation (you do not need to solve it! ) a tank initially contains 200 l of water, into which 50 g of salt has been dissolved. a solution of 10 g/l of salt is flowing into the tank at 20 l/min, and the resulting mixed solution is flowing out at a rate of 25 1/min. how much salt will be in the tank at any time t, 0

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
