Enter the matrix 8 9 9 6 3 6 2 8 3 1 8 3 8 5 7 9 7 1 6 3 4 9 1 4 9 8 1 2 2 15 2 4 8 7 9 8 8 4 6 2 8 A = 5 4 8 2 6 7 8 2 2 8 5 3 2 6 9 6 8 5 7 3 1 7 3 7 4 4 5 2 2 5 7 1 8 2 1 3 9 3 7 1 1 2 7 1 5 4 6 6 6 9 1 7 8 5 1 To prevent typing errors you may copy and paste following Maple command for entering A. A := Matrix([[8, 8, 7, 9, 9, 6, 3, 6, 2, 8, 3], [1, 1, 8, 3, 8, 5, 7, 9, 7, 1, 6], [3, 4, 2, 1, 1, 7, 4, 7, 4, 6, 5], [4, 9, 1, 4, 9, 8, 1, 2, 2, 1, 5], [2, 4, 8, 7, 9, 8, 8, 4, 6, 2, 8], [5, 4, 8, 2, 6, 7, 8, 2, 2, 8, 5], [3, 2, 6, 9, 6, 8, 5, 7, 3, 1, 7], [3, 7, 4, 4, 5, 2, 2, 5, 7, 1, 8], [2, 1, 3, 9, 3, 7, 1, 1, 2, 7, 1], [5, 4, 6, 6, 6, 9, 1, 7, 8, 5, 1]]); [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 7 from A and the matrix C that is made from columns 1 to 6 and 8 to 11 of A (in the same order as the columns of A). Now solve the matrix equation Cx =b and enter the 4" component of the unique vector solution for x in the box below. (Your answer should be an exact fraction, not a decimal.)
