HW10 Problems HW10P1 (20 points) Let As[2-1-2] -4 1-2 a. (3 pts) Find the determinant of the matrix A by using an expansion along row 1. b. (3 pts) Find the determinant of the matrix A by using an expansion along row 2. c. (3 pts) Find the determinant of the matrix A by using an expansion along column 2. d. (2 pts) Interchange rows 1 and 3 of the matrix A, and find the determinant of the transformed matrix without expansion along any row/column. (Hint: Use the determinant properties.) e(2 pts) Multply row 1 of the transformed matri oundin part (a) by -2, and ind the determinant of the new matrix. (Hint: Use the determinant properties.) f. (5 pts) Replace row 3 of the matrix found in part (e) with the sum of row 3 and -2 times row 1 and find the determinant of the new matrix in two ways: First, use an expansion along row 3 of the new matrix. Second, use the value for the determinant that has already been calculated in (e) and the determinant properties. & (2 pts) Does the matrix A have an i EAS 230-Fall 2017-Lab10& HW10
