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:

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
