1 Let A= 8 We want to determine if the columns of matrix A and are linearly independent. To do that we row reduce A To do this we add times the first row to the second. We conclude that A. The columns of A are linearly dependent. O B. The columns of A are linearly independent. O C. We cannot tell if the columns of A are linearly independent or not.

R assignment
In the matrix() function: . The first argument is the collection of elements that R will arrange into the rows and columns of the matrix. Here, we use 1:9 which is a shortcut for c(1, 2, 3, 4, 5, 6, 7, 8, 9) e The argument byrow indicates that the matrix is filled by the rows. If we want the matrix to be filled by the columns, we just place byrow FALSE. . The third argument nrow indicates...
