Suppose you have two 3 by 3 matrices ,say A and B How can the square of the A and B be mathematically expressed a).AB² b).[AB]² Which one the two is correct?

Answers

Answer 1

Answer:

[tex][AB]^2[/tex]

Step-by-step explanation:

Given

Matrices A and B

Required

Represents the square of A and B

The interpretation of the question is that:

The square of the product of A and B

This can be represented as:

The square(product of A and B)

Product means *

So, we have:

The square(A * B)

The square means ^2

So, we have:

[tex][A * B]^2[/tex]

This gives:

[tex][AB]^2[/tex]

Hence, the second option is correct

Wed Apr 21

Answers

Answer:

Options C and D are the correct options.

Step-by-step explanation:

Option A

cos(H) = 0.3846

By applying cosine rule in ΔFGH,

cos(H) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

           = [tex]\frac{36}{39}[/tex]

           = 0.9231

False

Option B

cos(G) = 0.9231

By applying cosine rule in ΔFGH,

cos(G) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

           = [tex]\frac{15}{39}[/tex]

           = 0.3846

False

Option C

sinG = 0.9231

By applying sine rule in ΔFGH,

sin(G) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

          = [tex]\frac{36}{39}[/tex]

          = 0.9231

True

Option D

tanG = 2.4

By applying tangent rule in ΔFGH,

tanG = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

        = [tex]\frac{36}{15}[/tex]

        = 2.4

True

Therefore, Options C and D are the correct options.

Step-by-step explanation:

These angles add up to 90 degrees

Hope this helps!

Answer:

∠AGF and ∠FGE, or ∠BGC and ∠CGD

Explanation

complementary angles are any angles which add up to 90°. since ∠AGB is a right angle according to the diagram, and AGD as well as BGE are straight lines (assumption), ∠DGE is also equivalent to 90° (opposite angles).

thus, the sum of ∠AGE and ∠BGD would be 90° each, so we know that ∠AGF and ∠FGE or ∠BGC and ∠CGD each add up to 90°.

It can be deduced that the addition of -3 and 4 will be 1.

How to add the numbers

It can be deduced that the addition of -3 and 4 will be;

= -3 + 4

= 1

When the winning score in golf is the lowest number, the lowest number is -1.

The value of the expression -273 - (-576) will be:

= -273 - (-576)

= -273 + 576

= 303

Also, -56/4 = -14. The value of the expression (2 - 19) + (-12) will be:

= (2 - 19) + (-12)

= -17 - 12

= -29

The value of -2x = 22 will be:

-2x = 22

Divide both side by -2

-2x/-2 = 22/-2

x = -11

The value of 5 + 3x = -22 will be;

5 + 3x = -22

5x = - 22 - 5

3x = -27

x = -27/3 = -9

5(x + 3) = 35

5x + 15 = 35

5x = 35 - 15

5x = 20.

5x/5 = 20/5

x = 4

The two numbers are 7 and 10 whose sum is 17 and whose difference is 3.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given that the sum of two numbers is 17 and the difference of those same two numbers is 3.

We need to find those two numbers.

Let x and y are the two numbers.

Sum of two numbers is 17

x+y=17..(1)

Difference of two numbers is 3

x-y=3..(2)

From equation 1,

x=17-y

Now substitute this in equation 2.

17-y-y=3

17-2y=3

17-3=2y

14=2y

Divide both sides by 2

y=7

Now add y value in equation 1

x+7=17

Subtract 7 from both sides

x=10

Hence, the two numbers are 7 and 10.

In the rectagular prism shown below, GH is parallel to EF. If the equation of GH is 6y-x=2, could the equation of EF be 4=y-1/6x? Explain your reasoning.

Answers

Answer:

Yes

Step-by-step explanation:

Given

GH:

[tex]-6y - x = 2[/tex]

Required

Can EF be

[tex]4 = y - \frac{1}{6}x[/tex]

First, we determine the slope of GH

[tex]-6y - x = 2[/tex]

Solve for 6y

[tex]6y = -x - 2[/tex]

Solve for y

[tex]y = -\frac{1}{6}x - \frac{2}{6}[/tex]

[tex]y = -\frac{1}{6}x - \frac{1}{3}[/tex]

An equation has the form:

[tex]y =mx + b[/tex]

Where

[tex]m = slope[/tex]

By comparison:

[tex]m = -\frac{1}{6}[/tex]

Next, determine the slope of EF

[tex]4 = y - \frac{1}{6}x[/tex]

Make y the subject

[tex]y = -\frac{1}{6}x + 4[/tex]

The slope is:

[tex]m = -\frac{1}{6}[/tex]

Compare the slopes of both lines.

[tex]m=m = -\frac{1}{6}[/tex]

Since they have the same slopes, then the equation of EF is possible

What happen in Vietnam war?

Troops from the United States and South Vietnam targeted North Vietnamese and Viet Cong hideouts in Cambodia and Laos.

Although being a military defeat, the Tet Offensive was a stunning propaganda win for communists. In fact, it is frequently regarded for changing the tide of the war in their favour.

As Viet Cong rebels invaded rural areas previously held by the South Vietnamese government, the South Vietnamese began to lose authority.

Despite tremendous deaths, North Vietnam secured a strategic triumph with the Tet Offensive, which represented a watershed moment in the Vietnam War and the start of the protracted, agonising American withdrawal from the region.
