"matrix multiplication" please respond to the following: determine whether or not matrix multiplication is commutative. support your answer using at least one (1) real-world example of scenario.

Matrix multiplication is not commutative.

Step-by-step explanation:

Matrix multiplication is not commutative which means that the result of A*B is not equal to the result of B*A which suggests that the order does matter in matrix multiplication.

AB ≠ BA

Real-world Example:

We can model a set of equations that will represent the number of games  won by each team.

Let x represents team Brazil and y represents team Spain.

2x + 3y = 12

6x + 8y = 34

In the matrix form

When we solve this matrix we get x = 3 and and y = 2

Which means that Brazil has won 3 games and Spain has won 2 games.

Now if you change the order of these variables then you wont get the correct results and this is exactly why matrix multiplication is not commutative because the order is important in matrix multiplication.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
