Example Questions

Example Question #123 : Vector & Matrix Quantities

Compute the sum of the two matrices.

$\begin{bmatrix} 4 & 1 & 0\\ 5& 1&3 \end{bmatrix} + \begin{bmatrix} 5&0 &2 \\ 3&-2 & 5 \end{bmatrix}$

Possible Answers:

$\begin{bmatrix} 9&-1 &-2 \\ 8& -1& 8 \end{bmatrix}$

$\begin{bmatrix} 9&1 &8 \\ 8& -1& 2 \end{bmatrix}$

$\begin{bmatrix} -9&1 &2 \\ 8& -1& 8 \end{bmatrix}$

$\begin{bmatrix} 9&1 &2 \\ 8& 1& 8 \end{bmatrix}$

$\begin{bmatrix} 9&1 &2 \\ 8& -1& 8 \end{bmatrix}$

Correct answer:

$\begin{bmatrix} 9&1 &2 \\ 8& -1& 8 \end{bmatrix}$

Explanation:

In order to compute the sum of the two matrices, we need to sum up identical entries. This means we sum up , and , then , and , and etc. The computation in general looks like the following.

$\begin{bmatrix} a_1 & a_2 & a_3\\ b_1& b_2& b_3 \end{bmatrix} + \begin{bmatrix} c_1&c_2 &c_3 \\ d_1&d_2 & d_3 \end{bmatrix}=\begin{bmatrix} a_1+c_1& a_2+c_2 & a_3+c_3 \\ b_1+d_1& b_2+d_2 & b_3+d_3 \end{bmatrix}$

Apply this to our problem to get,

$\begin{bmatrix} 4 & 1 & 0\\ 5& 1&3 \end{bmatrix} + \begin{bmatrix} 5&0 &2 \\ 3&-2 & 5 \end{bmatrix}=\begin{bmatrix} 4+5& 1+0 & 0+2 \\ 5+3& 1+(-2) & 3+5 \end{bmatrix}$

$=\begin{bmatrix} 9&1 &2 \\ 8& -1& 8 \end{bmatrix}$

Example Question #1 : Understanding The Multiplication Concept In Matrices As The Associative And Distributive Properties: Ccss.Math.Content.Hsn Vm.C.9

Which of the following properties does not apply to matrices?

Possible Answers:

Distributive

Associative

Commutative

None of the answers

Correct answer:

Commutative

Explanation:

Commutative does not apply to matrices because if we have matrices , and . It is not necessarily true that $A\times B=B\times A$ , even though in some cases it's true.

Example Question #131 : Vector & Matrix Quantities

Which is an example of two matrices satisfying the associative and distributive properties? Let a be a scalar, and A, B, and C be three unique matrices.

Possible Answers:

$A\times B=B\times A$

a(A+B)=aA+aB

a(A+B)+C=aA+(aB+C)

A+(B+C)=(A+B)+C

Correct answer:

a(A+B)+C=aA+(aB+C)

Explanation:

a(A+B)+C=aA+(aB+C) is the correct answer because it is the only answer that involves both the associative and distributive properties.
