Question

Mateus created a matrix using the elements below.

Answer 1

Mateus created in this case a matrix of
 3 rows
 3 columns
 as the number of rows and columns are equal, then by definition we created a square matrix
 answer
 a square matrix

Answer 2

Answer:

Mateus created a square matrix.

Step-by-step explanation:

•  Diagonal matrix are those matrix having non zero elements only on diagonal and rest all are zero.

• Square matrix are those having number of rows equal to number of columns.

• Zero matrix is a matrix having all elements equals to zero.

• Identity matrix are those matrix having one only on diagonal and rest all elements are zero.

Consider the given matrix:

$\left[\begin{array}{ccc}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}\end{array}\right]$

Put values as per given, we get,

$\left[\begin{array}{ccc}32&10&-9\\5&7.5&4\\-0.5&6&16\end{array}\right]$

Since, the given matrix is not diagonal , zero and identity matrix.

It only has number of rows equal to number of columns.

Hence, it is SQUARE MATRIX.

Thus, Mateus created a square matrix.
