Maple 1131W9T1 - Linear Algebra Current Grade: 16.0 / 20.0 Remaining Time: 237:53:00 Make sure to check out 'Self-Paced Lesson 7 - Linear Algebra' on Moodle. Question 6 Enter the matrix 9 8 9 9 8 3 7 1 3 6 9 4 points How Did I Do? 6 4 1 5 3 1 6 8 7 1 3 8 3 9 4 8 4 5 5 8 8 4 8 8 9 3 6 4 7 8 1 8 5 7 2 3 2 8 2 2 3 9 5 8 A = 9 8 1 6 7 7 5 6 1 5 1 8 8 4 8 2 9 2 5 1 6 3 1 6 3 6 2 9 6 1 6 1 9 7 7 6 1 5 8 4 8 6 5 2 2 1 3 7 3 2 8 5 2 7 6 To prevent typing errors you may copy and paste following Maple command for entering A. A := Matrix([[9, 8, 9, 9, 8, 3, 7, 1, 3, 6, 9], [6, 4, 1, 5, 3, 1, 6, 8, 7, 1, 3], [8, 3, 9, 4, 8, 4, 5, 5, 8, 8, 4], [8, 8, 9, 3, 6, 4, 7, 8, 1, 8, 5], [7, 2, 3, 2, 8, 2, 2, 3, 9, 5, 8], [9, 8, 1, 6, 7, 7, 5, 6, 1, 5, 1], [8, 8, 4, 8, 2, 9, 2, 5, 1, 6, 3], [1, 6, 3, 6, 2, 9, 6, 1, 6, 1, 9], [7, 7, 6, 1, 5, 8, 4, 8, 6, 5, 2], [2, 1, 3, 7, 3, 2, 8, 5, 2, 7, 6]]); [Note that Maple does not display the full matrix when it has more than 10 rows or 10 columns. However, you can still work with the matrix using Maple commands.] Use Maple to create the vector b that is column 4 from A and the matrix C that is made from columns 1 to 3 and 5 to 11 of A (in the same order as the columns of A). Now solve the matrix equation Cx =b and enter the 8th component of the unique vector solution for x in the box below. (Your answer should be an exact fraction, not a decimal.)
