Chapter 4.1, Problem 3CYU

To determine

To find: Thedimension of given matrix.

Answer to Problem 3CYU

The dimension of given matrixis $3\times 2$ .

Explanation of Solution

Given information:

The matrix is $\left[\begin{array}{cc}-1& 4\\ 2& 9\\ 17& 21\end{array}\right]$ .

Calculation:

Consider the matrix.

  $\left[\begin{array}{cc}-1& 4\\ 2& 9\\ 17& 21\end{array}\right]$

Since, the number of rows is 3 and number of column is 2.

Thus, the dimension of matrix is $3\times 2$ .
