How do you identify the dimensions of a matrix?
To identify the dimensions of a matrix, count the number of rows and columns it contains. The dimensions are expressed as "rows × columns." For example, a matrix with 3 rows and 4 columns is described as a 3×4 matrix.
Can a matrix with dimensions of 2 X 4 be added to another matrix that has dimensions of 2 X 4?
no
Can a matrix with dimensions of 2 X 4 be added to another matrix with dimensions of 2 X 4?
Yes.
What will be the dimensions of a new matrix formed by multiplying a 2 X 4 matrix and a 4 X 5 matrix?
It will be a 2 x 5 matrix.
How is the order of a matrix found?
The order of a matrix is another way of saying the dimensions of of a matrix. For a two dimensional matrix, the order could be 2 by 2, or 3 by 3, or 32 by 64.
Can a matrix with dimensions of 2 X 4 be added to another matrix with dimensions of 2 X 5?
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.
Can a matrix with dimensions of 4 X 5 be added to another matrix with dimensions of 5 X 3?
No. Matrix addition (or subtraction) is defined only for matrices of the same dimensions.
Can a matrix with dimensions of 2 X 4 be added to another matrix that has dimensions of 2 X 4?
no
Can a matrix with dimensions of 2 X 4 be added to another matrix with dimensions of 2 X 4?
Yes.
What will be the dimensions of the new matrix formed by multiplying a 3 X 4 matrix and a 4 X 1 matrix?
3x1 matrix
What will be the dimensions of the new matrix formed by multiplying a 2 by 4 matrix and a 4 by 5 matrix?
2 x 5 matrix
What are the dimensions of the matrix product?
2*2
Can a matrix with a dimensions of 2x4 be added to another matrix with dimensions of 2x4?
Yes. In general, two matrices of the same size can be added.
What will be the dimensions of a new matrix formed by multiplying a 2 X 4 matrix and a 4 X 5 matrix?
It will be a 2 x 5 matrix.
Can a matrix of 4x5 be added with a matrix with dimensions of 5x3?
No. You can only add matrices of the same size.
What will be the dimensions of the new matrix formed by multiplying a 7 X 2 matrix and a 2 X 6 matrix?
7 x 6A+
