We are given 12 to the 3rd power over 12 to 7th power.

First we write given expression as exponent form and we get It looks ..

If base is same in division then their exponent subtract.

Thus, It would be 1 over 12 to the 4th.

Answer:

90°

Step-by-step explanation:

Two lines intersect each other at a right angle, making them perpendicular. Thus, the resulting angles will all be 90°, making ∠4 = 90°.

Alternatively, we can use the supplementary angles equation.

Let's call the right angle marked in the picture ∠5.

∠4 + ∠5 = 180°, since the line is also a straight angle which measures 180°.

∠4 + 90° = 180°

∠4 = 90°

Either way, ∠4 = 90°

Hope this helps!

Answer:

x = 108

Step-by-step explanation:

∠RQS = ∠QLK = x ( corresponding angles )

∠QLK and ∠KLM form a straight angle and are supplementary, thus

∠QLK + ∠KLM = 180 ← substitute values

x + x - 36 = 180

2x - 36 = 180 ( add 36 to both sides )

2x = 216 ( divide both sides by 2 )

x = 108

Answer:

108

Step-by-step explanation:

Answer:

A) -43

Step-by-step explanation:

The absolute value is the distance from 0... which means you take the number and if there's a negative sign in front of it, you remove it.

-43 becomes 43 as an absolute value... so it's bigger than the others (23, 0, and 18).

Answer is then A) -43

Answer: hypothesis

Step-by-step explanation:

Answer:

The correct word is hypothesis.

Step-by-step explanation:

If a conditional statement is true and its HYPOTHESIS is true, then the conclusion is true.

The conditional statement is written in the following form -

If p is true, then q is true.

Here p is the hypothesis and q is the conclusion.

The opposite can be defined as - if the hypothesis is true and the conclusion is false, then the conditional statement is false.

Answer:

The maximum possible area of the triangle is 36 units²

Step-by-step explanation:

Let

x, y the legs of the right triangle

Applying the Pythagoras Theorem

[tex]12^{2}=x^{2}+y^{2}\\\\144=x^{2}+y^{2}[/tex]

[tex]y=\sqrt{144-x^{2}}[/tex] ----> equation A

The area of the right triangle is equal to

[tex]A=\frac{1}{2}xy[/tex] ----> equation B

substitute equation A in equation B

[tex]A=\frac{1}{2}x(\sqrt{144-x^{2}})[/tex]

Using a graphing tool

The vertex of the graph is a maximum

That means

The x-coordinate of the vertex is the value of x for the maximum possible area of the triangle

The y-coordinate of the vertex is the maximum possible area of the triangle

The vertex is the point (8.485,36)

see the attached figure

therefore

The maximum possible area of the triangle is 36 units²

the answer is c. 16.4 feet in 5 meters

Answer:

16.4 ft

Step-by-step explanation:

We are given that Yvette measured the length of her driveway to be 5 meters long.

We have to find that which is equivalent to  given length in given options.

Measurement of length = 5 m

We know that 1 meter =3.28 foot

1 meter=1.09 yard

1 meter =39.37 inches

5 m= [tex]5\times 3.28=16.4  ft[/tex]

5 m=[tex]5\times .109=5.45 yard[/tex]

5 m=[tex]5\times 39.37=196.85 inches[/tex]

Hence, measurement of length =5 m =16.4 ft

pretty much by simply solving for "y".

Answer:

y = -3/2 x +3

Step-by-step explanation:

Slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

3x+2y = 6

Subtract 3x from each side

3x-3x+2y = -3x+6

2y = -3x+6

Divide each side by 2

2y/2 = -3x/2 +6/2

y = -3/2 x +3

This is in slope intercept form where the slope is -3/2 and the y intercept is 3

Answer:

16cm

Step-by-step explanation:

To find the diameter we must first find the radius and multiply by 2.

The isosceles triangle that has the length of a leg to be 8cm and a vertex angle of [tex]120\degree[/tex] that has been circumscribed is shown in the attachment.

We draw a line from the vertex of the isosceles triangle that bisects the base through the center O of the circle.

This implies that [tex]m\angle OAC=60\degree[/tex].

Based on this [tex]m\angle ACO=60\degree[/tex] because the two radii are equal.

It follows that:[tex]m\angle AOC=60\degree[/tex] because sum of angles in a triangle must be 180 degrees.

This means that, triangle AOC is an equilateral triangle, hence all sides are equal.

One side of this equilateral triangle happens to be the side of the leg of the isosceles triangle which is 8cm.

It follows that, the radius of the circle is 8cm.

Therefore the diameter of the circle is 16cm

Hello There!

So we divide fractions by multiplying by the reciprocal.

So let’s change 6/7 divided by 3/8 to 6/7 multiplied by 8/3.

Once we do that, we can start our multiplication.

Once we multiply, we get 48/21

We can both divide these by 3 to simplify it so once we divide we will get

Answer:

8 units

Step-by-step explanation:

mid point of hypotenuse of right angled isosceles triangle is equidistant from three vertices.

length of altitude=16/2=8

The question is incomplete, here is a complete question.

Triangle FGH is an isosceles right triangle with a hypotenuse that measures 16 units. An altitude, GJ, is drawn from the right angle to the hypotenuse.

What is the length of GJ?

A. 2 units

B. 4 units

C. 6 units

D. 8 units

Answer : The correct option is, (D) 8 units

Step-by-step explanation :

Given:

Length FH = 16 unit

As we know that a altitude between the two equal legs of an isosceles triangle creates right angles is a angle and opposite side bisector.

Thus,

Length FJ = Length HJ = [tex]\frac{16}{2}[/tex] = 8 units

As, the triangle is an isosceles. So, length GF = length GH = x unit

First we have to determine the value of 'x'.

Using Pythagoras theorem in ΔFGH :

[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]

[tex](FH)^2=(GF)^2+(GH)^2[/tex]

Now put all the values in the above expression, we get :

[tex](16)^2=(x)^2+(x)^2[/tex]

[tex]256=2x^2[/tex]

[tex]x^2=128[/tex]

[tex]x=8\sqrt{2}[/tex]

Thus, length GF = length GH = x unit = [tex]8\sqrt{2}[/tex]

Now we have to determine the length GJ.

Using Pythagoras theorem in ΔGJH :

[tex](Hypotenuse)^2=(Perpendicular)^2+(Base)^2[/tex]

[tex](GH)^2=(GJ)^2+(HJ)^2[/tex]

Now put all the values in the above expression, we get :

[tex](8\sqrt{2})^2=(GJ)^2+(8)^2[/tex]

[tex]128=(GJ)^2+64[/tex]

[tex](GJ)^2=128-64[/tex]

[tex](GJ)^2=64[/tex]

[tex]GJ=\sqrt{64}[/tex]

[tex]GJ=8[/tex]

Thus, the length of GJ is, 8 units.

Answer:

Is not a function

Step-by-step explanation:

A relation is a function  if each value of the input set (domain) is assigned only one value of the output set (range)

Given a function [tex]f(x)[/tex], the inverse of f denoted  [tex]f ^ {- 1}(x)[/tex] is a function only if f(x) is a one-to-one function. This means that there are not in the domain of [tex]f(x)[/tex] two distinct values of x that produce the same value of y.

In the graph of f(x) you can see that the function is not one-to-one. Since [tex]f(x) = (-x)[/tex] for all x.

For example:

[tex]f(1) = f (-1)\\\\f (2) = f (-2)\\\\[/tex]

Observe the attached graph

In general, the inverse of a quadratic function f(x) is not a function

Answer:

Option B  13 units is correct.

Step-by-step explanation:

The formula used to find distance between 2 points is:

[tex]d(P1,P2)=\sqrt{(x_{2} -x_{1})^2 + (y_{2} -y_{1})^2 }[/tex]

x₁ = 12 x₂ = 0 y₁= 9 and y₂=4

Putting values in the formula:

[tex]=\sqrt{(0-12)^2+(4-9)^2}\\=\sqrt{(-12)^2+(-5)^2}\\=\sqrt{144+25} \\=\sqrt{169} \\=13[/tex]

So, Option B 13 units is correct.

Answer:

B) 13 units

Step-by-step explanation:

1) Use the equation for solving the distance between points:

√(x2 - x1)²+(y2-y1)²

2) In this case, we would plug them into the equation:

√(12-0)²+(9-4)²

3) Now, we simplify:

√(12)²+(5)²

4) We simplify even further:

√144+25

5) We add the two:

√169

6) Take the square root of √169:

13.

284,000

(You would round up one because the number right before the thousands place is the hundred, which in our case, is above 4. As such, we are going to round up to 284,000.)

Hope I could help! :)

When rounding 283,657 to the nearest thousand, we look at the hundreds digit which is 6. Since it is greater than 5, we round up, resulting in a final rounded number of 284,000.

To round 283,657 to the nearest thousand, we look at the hundreds place to decide whether to round up or down. Since the hundreds digit is a '6' (which is greater than 5), we round up to the next thousand. Therefore, 283,657 rounded to the nearest thousand is 284,000.

Rounding rules dictate that if the digit to the right of the target rounding place is 5 or greater, we round up the target digit by one. In this case, we're rounding to the nearest thousand, so we look at the hundreds place which is a 6. Since it is greater than 5, we add one to the thousands place, changing 283,000 to 284,000, and set all the following digits to zero, giving us our final rounded number.

Step-by-step explanation:

1) x^2-6=0

2) Factor out the X.  x*(x-6)=0

3) x* (x - 6) =0 When the product of factors equal zero at least one factor is zero.

x=0

x-6=0

4)Solve for "x-6=0" for X. Move constant to the right by adding its opposite to both sides  

x-6 +6 = 0 +6

Eliminate the opposites

x - 6 + 6 = 0 + 6

x= 0+6

x=6

Answer: [tex](2g+h)[/tex] and [tex](2g-h)[/tex]

Step-by-step explanation:

The area of a rectangle is obtained by multiplying its lenght by its width.

You know that the area of this rectangle is [tex]4g^2- h^2[/tex], then you need to apply the Difference of squares to find the dimensions of this rectangle.

Remember that the Difference of squares is:

[tex]a^2-b^2=(a+b)(a-b)[/tex]

Then, applying this, you get:

 [tex]4g^2- h^2=(2g+h)(2g-h)[/tex]

Therefore, now you know that the dimensions are:

[tex](2g+h)[/tex] and [tex](2g-h)[/tex]

the length and breadth of rectangle are [tex]2g - h[/tex] and [tex]2g + h[/tex] respectively

The given expression for the area of the rectangle is [tex]4g^2 - h^2[/tex]

This expression is a difference of squares, which can be factored using the formula: [tex]a^2 - b^2 = (a - b)(a + b)[/tex]

Now by comparing both equations we can factor as follows:

[tex]4g^2 - h^2 = (2g)^2 - h^2\\\\4g^2 - h^2 = (2g+h)(2g-h)[/tex]

We know that area of a rectangle is a product of its length and breadth so we can say that:

Length: 2g - h

Breadth: 2g + h

So, the length and breadth of rectangle are [tex]2g - h[/tex] and [tex]2g + h[/tex] respectively
