In the diagram, which pair of angles are vertical angles?
•<1 and <2
•<4 and<6
•<6 and <8
•<5 and <3

Answer:

Domain: [0, 4]

Range: [0, 4]

Function? Yes

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, our x-values span from 0 to 4. Since both are closed dot, they are inclusive in the domain:

Interval Notation - [0, 4]

Inequality Notation - 0 ≤ x ≤ 4

According to the graph, our y-values span from 0 to 4. Since both are closed dot, they are inclusive in the range:

Interval Notation - [0, 4]

Inequality Notation - 0 ≤ x ≤ 4

Since we see that each x-value has a unique y-value and passes the vertical line test.

∴ the relation is a function.

Answer:

$57.51

Step-by-step explanation:

If the price of a sweater was $37.38 after a 35% discount, what was the original price? Round your answer to the nearest cent.

The formula for the original price =

= Sales price/1 - Percentage discount

Percentage discount = 35% = 0.35

Original price = $37.38/1 - 0.35

= $37.38/0.65

= $57.507692308

Approximately = $57.51

Therefore, the original price H= $57.51

Answer:

3

Step-by-step explanation:

When you divide two negative numbers, the answer is positive. Since - 15 and -5 are both negative, the answer will have to be positive. Divide 15/5 (just as you would with postive numbers) to get 3 and don't do anything else. The answer has to be 3 because 3 * - 5 = -15 (the opposite of division is multiplication).

Answer:

r = sq rt [v/(h x Pi)]

r = 1.69

Step-by-step explanation:

v=h x Pi x r^2

r^2 = v/(h x Pi)

r = sq rt [v/(h x Pi)]

r = sq rt [67.57 / (7.5 x 3.14)]

r = sq rt 2.8692

r = 1.69

Step-by-step explanation:

Remark

This is an example of the distributive property. Of all the fundamental rules used in solving equations, this is likely the most important, at least at beginning levels.

Solution

What this is saying is two things.

1. you must multiply both terms on either side of the + sign by the factor outside the brackets.

2. You must not destroy a plus (or minus) sign unless the two terms inside the brackets are exactly the same.

3(7 + x)           The terms are not the same, so your answer must have a plus sign

Left side of the plus: 3*7

Right side of the plus: 3 * x

The answer then is 21 + 3x

It is more commonly written as 3x + 21

p=4

Q=2

plot an x onto the 4 on th y line and a 2 on the x line

then draw a horizontal line with the ruler provided through 4 and 2

hope it helps :)

The solution to the equations are

a) The coordinates of point P is P ( 0 , 4 ) and Q is Q ( 2 , 0 )

b) The graph is plotted with points P and Q

c) The equation of line is 4x + 2y = 8

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

4x + 2y = 8   be equation (1)

Now , the coordinates of the point P = P ( 0 , y )

The coordinates of the point Q = Q ( x , 0 )

Substituting the values in the equation , we get

when x = 0

4 ( 0 ) + 2y = 8

2y = 8

y = 4

So , the coordinates of the point P = P ( 0 , 4 )

when y = 0

4x + 2 ( 0 ) = 8

4x = 8

x = 2

So , the coordinates of the point Q = Q ( 2 , 0 )

Now , the equation of line is 4x + 2y = 8

when x = { -2 , -1 , 0 , 1 , 2 , 3 }

The values of y are y = { 8 , 6 , 4 , 2 , 0 }

So, the line is plotted in the graph

Hence , the equation of line is 4x + 2y = 8

Answer:

The anwer is below.

Step-by-step explanation:

To calculate mean a.k.a average of something is when you add all of the numbers in the set and then multiply by the number of numbers there were.

an example : 4, 5,6,7 = 4+ 5 + 6 + 7 + 3 = 25 divided by 5 ( the number of numbers there were ) which is 5 so the mean is 5

To calculate the median you have to organize the set of numbers from least to greatest choose the middle number and that's the median, If there is an even number of numbers in the set then you add the two middle numbers and divide it by 2.  

an example : 5,7, 8, 4 =  4, 5, 7 , 8 = the middle numbers = 5 + 7 = 12 divided by 2 = 6

To calculate the mode you have to see which numbers comes more often in the set of numbers, If there are two different numbers that come often even if one is higher include them in the mode.

An example - 5,6,6,6,6,7,7,7. The mode in this is 6 but 7 comes often to so if your teacher tells you to include more than one mode in these kinds of situation you include 7 or in general you don't have to

To calculate the range you choose the greatest and the lowest numbers and substract the highest to the lowest number in the set.

An example  5, 6, 7 , 9 , 8 = 9 ( the highest number in this set) - ( substraction) 5 ( the lowest number in this set) and 9 - 5 = 4 so the range is 4

i think the answer is

a/b like a divided by b is the answer

cuz 8 ÷ 3 = 2.7

and 24 ÷ 9 = 2.7

and 40 ÷ 15 = 2.7

so maybe like

b · 2.7 = a

hope this helpsss

Answer:

well on side A, it starts off on 8 (as you can see) and adds 16, which gives you 24, then add another 16 and that gives you 40. Then on side B, it starts with 3, adds 6 which gives you 6, then add another 6 and you'll have 15.

Answer:

225 rooms

Step-by-step explanation:

Find 1/2 or 50% of 450. 50% of 450 is 225. So 225 rooms are full, and 225 are empty.

The length and width are 18 meters and 6 meters respectively.

Given that

We know that

The perimeter of the rectangle be

48 = 2 (length + breadth)

48 = 2(3x + x)

48 = 6x + 2x

48 = 8x

x = 6

So, the width is 6 meters.

And, the length be 18 meters.

Therefore we can conclude that The length and width are 18 meters and 6 meters respectively.

[tex]h= 2x[/tex]

Step-by-step explanation:

Given

Square

[tex]Side = x[/tex]

Triangle

[tex]Base = x[/tex]

[tex]Altitude = h[/tex]

Required

Find h, if both shapes have the same area

The area of the square is:

[tex]Area = x * x[/tex]

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

The area of the triangle is:

[tex]Area = \frac{1}{2} * Base*Height[/tex]

[tex]Area = \frac{1}{2} * x*h[/tex]

Equate both areas

[tex]x^2 = \frac{1}{2} * x*h[/tex]

Divide both sides by x

[tex]x = \frac{1}{2} *h[/tex]

Multiply both sides by 2

[tex]2*x = \frac{1}{2} *h*2[/tex]

[tex]2x = h[/tex]

[tex]h= 2x[/tex]

Answer:

  12 cm

Step-by-step explanation:

The distance to the chord is the median of an isosceles right triangle with hypotenuse 20 and leg 16. This 5:4 ratio suggests the other leg of that right triangle would make the ratios 3 : 4 : 5, so is 12.

The chords are 12 cm from the center.

_____

You can, of course, use the Pythagorean theorem. If c is half the chord length and d is the distance to the chord, you have ...

  c² + d² = r²

  16² + d² = 20²

  d² = 400 -256 = 144

  d = √144 = 12 . . . . . cm
