Matrics Assisment Q.3) If A = [1 0 5 ; 0 2 1 ; 0 3 4] and B = [2 5 1 ; 0 1 7 ; 4 3 3] then find AB

ans=[21319;02329;41535]

Step-by-step explanation:

I think the ans will be =[21319;02329;41535]

I hope it will help u

Here:

Therefore, the matrix AB will be:

Therefore:

Matrix: A matrix is a rectangular arrangement of numbers in the form of horizontal and vertical lines.

Horizontal lines are called rows and vertical lines are called columns.

Order of Matrix:

A matrix containing x rows and y column has order x × y and it has xy elements.

Different types of matrices:

Row Matrix: This type of matrices have only 1 row. Example:

Column Matrix: This type of matrices have only 1 column. Example:

Square Matrix: In this type of matrix, number of rows and columns are equal. Example:

Zero Matrix: It is a matrix with all elements present is zero. Example:

Identity Matrix: In this type of matrix, diagonal element is 1 and remaining elements are zero. An Identity matrix is always a square matrix. Example:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
