Quizplus · Accepted Answer

The matrix A has 3 rows and 1 column, making it a 3 × 1 matrix, which is a column matrix.

Determine the Size of Matrix a and Tell Whether It A=[−6.5−1.61.3]A = \left[ \begin{array} { r } - 6.5 \\- 1.6 \\1.3\end{array} \right]A=​−6.5−1.61.3​​

Determine the Size of Matrix a and Tell Whether It $A = \left[ \begin{array} { r } - 6.5 \\- 1.6 \\1.3\end{array} \right]$
