Chapter 4: Q46. (page 166)

State the dimensions of each matrix.

46.51鈭�62鈭�38573

Short Answer

Expert verified

The dimension of the matrix is 2脳4.

Step by step solution

01

- Define the dimension of the matrix

A matrix A with m rows and n columns is a matrix of dimensions m脳n.

02

- State an example

Let us consider a matrix A=12鈭�3014. Clearly, matrix A has 2 rows and 3 columns, therefore, the dimension of matrix A will be 2脳3.

03

- State the dimension of 51−62−38573

In order to state the dimension of the matrix 51鈭�62鈭�38573, observe that the matrix has 2 rows and 4 columns, therefore, the dimension of matrix will be 2脳4.
