Question
I have to create a question. I want to use Gauss elimination AND Substitution method. I also want them to create a mathlab code....I have created the question below. Please tell me what I need to change in order for this question to work. You can change whatever you need to in the question. I just need this question to be solveable!!!
Ryan has a total of 112 hours of free time in the next 2 weeks before his finals start. Ryan has 45 hours this week to study and 67 hours next week. Ryan wanted to split up these hours between his 3 classes, but he knows that some classes need more time than others. Ryan wrote down all 3 classes and established a percentage of importance for each class 1. CLASS PERCENTAGE OF IMPORTANCE 22% 43% 35% Introduction to Thermodynamics Introduction to Fluid Mechanics Applied Numerical Methods Given the percentages, what amount of time should Ryan spend on each class to set himself up the percentages or classes, he could do so. By hand, use the Substitution Technique and Gauss for success for finals? Write a Mattlab code that will find the results,soif Ryan needed to change Elimination methodExplanation / Answer
Increase the number of class. To perform row reduction on a matrix, one uses a sequence of elementary row operations to modify the matrix until the lower left-hand corner of the matrix is filled with zeros, as much as possible. There are three types of elementary row operations: 1) Swapping two rows, 2) Multiplying a row by a non-zero number, 3) Adding a multiple of one row to another row. Using these operations, a matrix can always be transformed into an upper triangular matrix, and in fact one that is in row echelon form. Once all of the leading coefficients (the left-most non-zero entry in each row) are 1, and every column containing a leading coefficient has zeros elsewhere, the matrix is said to be in reduced row echelon form. This final form is unique; in other words, it is independent of the sequence of row operations used. For example, in the following sequence of row operations (where multiple elementary operations might be done at each step), the third and fourth matrices are the ones in row echelon form, and the final matrix is the unique reduced row echelon form.
