Compute the product using the methods below. If a product is undefined, explain why. A. The definition where Ax is the linear combination of the columns of A using the corresponding entries in x as weights. B. The row-vector rule for computing Ax.
1. Set up the linear combination of the columns of A using the corresponding entries in x as weights.
A. The matrix-vector Ax is not defined because the number of columns in matrix A does not match the number of entries in the vector x.
B. The matrix-vector Ax is not defined because the number of rows in matrix A does not match the number of entries in the vector x.
2. Set up the product Ax using the row-vector rule. Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice.
A. Do not simplify.
B. Do not simplify.
C. The matrix-vector Ax is not defined because the row-vector rule states that the number of columns in matrix A must match the number of entries in the vector.
D. The matrix vector Ax s not defined because the ro vector rule states that the number o rows in matrix A must match he number o entries in the vector x
