Explanation of Solution
Given:
From the given scenario, it is given that the three factories are available on the Momiss River. There are two types of pollutants emitted into the river and the if the waster form the factory is processed, the pollution in the river can be reduced.
Processing cost for factory 1 waste: $15
Processing cost for factory 2 waste: $10
Processing cost for factory 3 waste: $20
Consider the variable to represent the amount of waste in factory 1 is
Consider the variable to represent the amount of waste in factory 2 is
Consider the variable to represent the amount of waste in factory 3 is
The objective function obtained from the above calculation is
Considering the constraints,
Constraint 1: At least 30 tons of pollutant 1 must be reduced in the river.
Constraint 2: At least 40 tons of pollutant 2 must be reduced in the river

- For this question you will perform two levels of quicksort on an array containing these numbers: 59 41 61 73 43 57 50 13 96 88 42 77 27 95 32 89 In the first blank, enter the array contents after the top level partition. In the second blank, enter the array contents after one more partition of the left-hand subarray resulting from the first partition. In the third blank, enter the array contents after one more partition of the right-hand subarray resulting from the first partition. Print the numbers with a single space between them. Use the algorithm we covered in class, in which the first element of the subarray is the partition value. Question 1 options: Blank # 1 Blank # 2 Blank # 3arrow_forward1.
