3.3-2. Consider a problem with two decision variables, x₁ and x2,which represent the levels of activities 1 and 2, respectively. Foreach variable, the permissible values are 0, 1, and 2, where thefeasible combinations of these values for the two variables are de-termined from a variety of constraints. The objective is to maxi-mize a certain measure of performance denoted by Z. The values ofZ for the possibly feasible values of (x1, x2) are estimated to bethose given in the following table:X2x10120120364881361218Based on this information, indicate whether this problemcompletely satisfies each of the four assumptions of linear pro-gramming. Justify your answers.

To determine whether this problem satisfies the four assumptions of linear programming, let's…

s Alan Industries is expanding its product line to include three new products: A, B, and C. These are to be produced on the same production equipment, and the objective is to meet the demands for the three products using overtime where necessary. The demand forecast for the next four months, in hours required to make each product is: PRODUCT APRIL 870 670 770 Regular time Overtime MAY 670 770 570 JUNE 870 970 770 Because the products deteriorate rapidly, there is a high loss in quality and, consequently, a high carrying cost when a product is made and carried in inventory to meet future demand. Each hour's production carried into future months costs $3 per production hour for A. $4 for B, and $5 for C APRIL 1,570 770 Production can take place either during regular working hours or during overtime. Regular time is paid at $4 when working on A. $5 for B, and S6 for C. The overtime premium is 50 percent of the regular time cost per hour The number of production hours available for regular…

A mining company brings up a land purchase project for 61,000 TL. in order to extract coal. The annual net income of the coal mine is estimated at TL 20,000. At the end of the 10-year useful life, the company is obliged to spend 150.000 TL to make the land suitable for agriculture. Is the project suitable since the annual interest rate is i=10%? Solve according to NBD anal ysis..
Company X is planning to run a project that requires an initial investment of RM 80,000.Operation cost is estimated at RM 20,000 per year starting one year from the start of theproject until its project life. Starting second year onwards, the operation cost is expectedto increase by RM 5,000 from previous year. The project will start to generate its annualincome of RM 70,000 on the second year until fifth year. The salvage value of the projectis RM 50,000 and its project life is five years. a) Construct the cash flow diagram to summarize the above transactions. b) Determine the expected project value at the end of five years. Assume the growth rateis 12%.

Scenario You are going to plant a rectangular flower bed consisting of tulips in the middle surrounded by daisies on the outside. You have the same amount of each flower and will need an equal area for each. You want the border of daisies to be uniform around the tulips in the middle, as shown in the diagram below:
Problem 2 Suppose that for years East Campus' short-run Phillips Curve was such that each 1 percentage point increase in its unemployment rate was associated with a 2-percentage point decline in its inflation rate. Then, during several recent years, the short-run pattern changed such that its inflation rate rose by 3 percentage points for every 1 percentage point drop in its unemployment rate. Graphically, did East Campus' Phillips Curve shift upward or did it shift downward?
