Example of equal matrix​

Mathematics
1 answer:
Rina8888 [55]3 years ago

Two matrices are called equal matrices if they have the same order or dimension and the corresponding elements are equal.

Suppose A and B are the matrices of equal order i × j and aij = bij, then A are B are called equal matrices.

Example: Find the value of a and x if the matrices

A

=

[

4

3

1

−

5

]

,

B

=

[

a

x

−

6

1

−

5

]

are equal.

Solution:

Given that,

A = B

[

4

3

1

−

5

]

=

[

a

x

−

6

1

−

5

]

Since A and B are equal matrices the corresponding elements are equal.

Therefore,

a = 4

x – 6 = 3

x = 3 + 6

x = 9

just olya [345]

Answer:

48 {m}^{5}  {n}^{6}

Step-by-step explanation:

6{m}^{3}  {n}^{3}  \times 8 {m}^{2}  {n}^{3}

8 \times 6 = 48

So

6{m}^{3}  {n}^{3}  \times 8 {m}^{2}  {n}^{3}  = 48 {m}^{3 + 2} {n}^{3 + 3}

Therefore

48 {m}^{5}  {n}^{6}

Which relation is a function?
Brums [2.3K]
The second relation is a function.

For a relation to be a function, each x-value can only have a singular corresponding y-value. Since all other relations feature x-values with multiple y-values, the second relation is a function.

the width of a rectangle is 8 feet and the diagnal length of the rectangle is 13 feet which measurement is closest to the length
____ [38]

Answer:

Well the whole answer is 10.246950 smth smth but I don’t have the multiple choices so your gonna have to round yourself

Step-by-step explanation:

Okay so you have a weigh of 8 and a diagonal of 13.

If you look, theres a triangle there. One side has 8 and the diagonal that was cut forms a 13. So we have a leg and a hypotnuse. To find the other leg (length) just follow the Pythagorean theroum and solve for b or a.

Pythagorean theroum: a^2+b^2=c^2

Now subsitute c for 13 since its the hypotnuse and a or b as 8 but only one.

In this case I’m substituting a for 8.

8^2+b^2=13^2

Solve the squares

64+b^2= 169

Isolate the b

b^2=105

Now square root 105

√105 will give the answer above on a normal calculator but if you have to round, I don’t know what place but you can round.
