Solve the linear programming below by (a) graphing and (b)using simplex method.
A certain company makes 2 models of motorcycles, model 2A and model 2B. Both models pass through assembling and painting. A model 2A motorcycle needs 4 hours for in assembling and 3 hours in painting. A model 2B motorcycle needs 8 hours in assembling and 12 hours in painting. Machines in assembling are available for 64 hours, while those in painting, 72 hours. The profit for each model 2A motorcycle is P2700 and P3600 for a model 2B motorcycle. How many model 2A and 2B motorcycles must be manufactured to maximize profit? What is the maximum profit?

The beach is represented by the real line R and the location of the i-th person is some integer r; e Z. Your task is to prevent people from getting sunburned by covering them with umbrellas. Each umbrella corresponds to a closed interval I = [a, a + L] of length L e N, and the i-th person is covered by that umbrella if æ¡ € I. Design a greedy algorithm for covering all people with the minimum number of umbrellas. The input consists of the integers x1,..., En, and L. The output of your algorithm should be the positions of umbrellas. For example, if the input is r1 = 1, x2 = 3, r3 = 5, and L = 2, then an optimum solution is the set of two umbrellas placed at positions 2 and 5, covering intervals [1,3] and [4,6]. 1 2 3 4 5 6 Prove that your algorithm is correct and that it runs in time polynomial in n.arrow_forward
