Solve the problem.A 200 gallon tank is filled with pure water. A salt solution with a concentration of 16 g/gal flows into the tank at a rate of 3 gal/min. The thoroughly mixed solution is drained from the tank at a rate of 3 gal/min.(a) Write an initial value problem for the mass of the salt.(b) Solve the initial value problem.
A. (a) m'(t) = -0.015m + 3200, m(0) = 200 (b) m = 3200e-0.015t + 48 B. (a) m'(t) = 0.015m - 48, m(0) = 16 (b) m = -48e0.015t + 48 C. (a) m'(t) = -0.015m + 48, m(0) = 0 (b) m = -3200e-0.015t + e-0.015 D. (a) m'(t) = -0.015m + 48, m(0) = 0 (b) m = -3200e-0.015t + 3200
Provide an appropriate response.Suppose a TV dealer has stores A and B and warehouses C and D. The cost of shipping a TV is $18 from C to A, $9 from C to B, $24 from D to A, and $15 from D to B. Suppose that store A orders 25 TV sets and store B orders 30 TV sets. Also suppose that warehouse C has 40 TV sets and warehouse D has 45 TV sets available. Find the best way to minimize cost and find the minimum cost (Hint: Let x1 be the number of TV sets shipped from C to A and x2 be the number of TV sets shipped from C to B. Thus, 25 - x1 is the number of TV sets shipped from D to A and 30 - x2 is the number of TV sets shipped from D to B.)
