Please solve question 29

[Graphing Calculator] The amounts , (t) and x2(t) of salt in the two brine tanks of Fig. 5.2.8 satisfy the differential equations dx2 -kid1 + k212, = KIT1 - k2[2, dt dt where ki = r/Vi as usual. In Problems 29 and 30, solve for 1(t) and x2(t), assuming that r = 10 (gal/min), x1 (0) = 15 (lb), and x2(0) = 0. Then construct a figure showing the graphs of 1(t) and $2(t). Figure 5.2.8 The two brine tanks of Problems 29 and 30. Tank 1 Tank 2 29. Vi = 50 (gal), V2 = 25 (gal)
