Answer to relevant QuestionsRead the referenced article that fully describes the OR study summarized in the application vignette presented in Sec. 4.3. Briefly describe the application of the simplex method in this study. Then list the various ...Consider the following problem. Maximize Z = 5x1 + 3x2 + 4x3, Subject to and x1 ≥ 0, x2 ≥ 0, x3 ≥ 0. Repeat Prob. 4.4-3 for the following problem. Maximize Z = 2x1 + 3x2, Subject to and x1 ≥ 0, x2 ≥ 0. Follow the instructions of Prob. 4.5-2 when the constraints are the following: and x1 ≥ 0, x2 ≥ 0, In problem (a) Demonstrate graphically that the feasible region is unbounded. For the Big M method, explain why the simplex method never would choose an artificial variable to be an entering basic variable once all the artificial variables are nonbasic.
