- Determine the dimension of the matrix 14710238.arrow_forwardDetermine if the statement is true or false. If the statement is false, then correct it and make it true. A 75 matrix has 5 rows.arrow_forwardTake this test to review the material in Chapters 4 and 5. After you are finished, check your work against the answers in the back of the book. Write the third column of the matrix as a linear combination of the first two columns if possible. [102422751]arrow_forward
- Consider the matrix A=[2314]. Show that any of the three types of elementary row operations can be used to create a leading 1 at the top of the first column. Which do you prefer and why?arrow_forwardUse an example chosen from 22 matrices to show that for nn matrices A and B,ABBA but AB=BA.arrow_forwardSolve for a11, a12, a21 and a22 in the matrix equation a11a12a21a22=6324.arrow_forward
- Referring to Exercise 19, suppose that the unit cost of distributing the products to stores is the same for each product but varies by warehouse because of the distances involved. It costs $0.75 to distribute one unit from warehouse 1 and $1.00 to distribute one unit from warehouse 2. Organize these costs into a matrix C and then use matrix multiplication to compute the total cost of distributing each product.arrow_forwardWrite the system of equations that corresponds to the augmented matrix: [111423181113] .arrow_forwardSolve for x,y,z and w in the matrix equation wxyx=-432-1+2ywzx.arrow_forward
