The domain of the relation in the graph is:

{-2, -1, 0, 2, 5}

A relation maps elements from one set (the domain) into elements from another set (the range).

Such that the domain is represented in the horizontal axis.

In the graph, we can see the points:

{(-2, -3), (-1, -1), (0, 3), (2, 1), (5, 2)}

The domain is the set of the first values of these points, then the domain is:

{-2, -1, 0, 2, 5}

The correct option is the first one.

Step-by-step explanation:

Substitute n = 7 into f(n)

f(7) = 5 + 8(7 - 1) = 5 + 8(6) = 5 + 48 = 53

f(n) = 5 + 8(n - 1) represents the nth term of an arithmetic sequence

f(n) = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

By comparison, then

a₁ = 5 and common difference d = 8

Answer:

$214.

Step-by-step explanation:

30 hrs x 5 = 150.

Any hours above 30 = $8

8x8=64.

150+64=214

Answer:$214

Step-by-step explanation: To get 214 dollars we first find how much money Josi makes before exceeding 30 hrs which is 30 x 5 = $150

Then 38-30= 8hr extra so, if $8 per extra hour means 8 x 8 = $64 over time

Finally 150 + 64 =$214

The histograms typically are used to display continuous measures.

There are different types of charts: histogram, line chart, pie chart, and others.

The histogram is a type of chart used as a tool that provides a way to assess the distribution of data. From this type of chart, a set of data are previously tabulated and divided into classes. In the other words, the histogram is applied to summarize discrete or continuous measures, so it becomes more easily the understand the used data. There are many websites and software that allow the plot of this type of chart.

The value of x in the solution set of the inequality: - 2(3x+2) > -8x + 6 is x>5.

- 2(3x+2) > -8x + 6

Let's solve the inequality by isolating the variable x.

or, - 6x -4 > -8x + 6

Add 4 on both sides

or, - 6x - 4 + 4 > -8x + 6 + 4

or, -6x > -8x + 10

Add 8x on both sides

or, -6x + 8x > -8x +8x +10

or, 2x > 10

Divide both sides by 2

or, 2x/2 > 10/2

0r, x > 5

Hence, the value of x in the solution set of - 2(3x+2) > -8x + 6 is x>5.

Answer:

5

Step-by-step explanation:

Answer:

• \(x\) = 42°

• \(y\) = 74°  

• \(z\) = 114°

Step-by-step explanation:

To solve these problems, we have to use the triangle sum theorem, which states that "the sum of all the interior angles of a triangle is 180°".

A)

\(x\) + 90° + 48° = 180°

⇒ \(x\)  + 138° = 180°

⇒ \(x\) + 138° - 138° = 180° - 138°      [Subtracting 138° from both sides]

⇒ \(x\) = 42°

B)

The triangle in this question is an isosceles triangle, therefore the two angles at the base of the triangle are equal and have measures of \(y\).

\(y\) + \(y\) + 32° = 180°

⇒ 2\(y\) + 32° = 180°

⇒ 2\(y\) = 180° - 32°

⇒ 2\(y\) = 148°

⇒ \(\frac{2}{2} y\) = \(\frac{148^{\circ}}{2}\)             [Dividing both sides by 2]

⇒ \(y\) = 74°                    

C)

\(z\) + 28° + 38° = 180°

⇒ \(z\) + 66 = 180°

⇒ \(z\)  = 180° - 66°

⇒ \(z\) = 114°

Answer:

Perimeter of a polygon with 31 sides = (side length) x 31 = 279 units

Area of a polygon with 31 sides = (n x Side2 x cot (Π/n))/4 = (n x 92 x cot (Π/31))/4 = 6173.16 square units

Sum of the interior angles of a polygon with 31 sides = (n-2) x 180 degrees = (31-2) x 180 degrees = 5220 degrees

Interior Angle of a polygon with 31 sides = (n-2) x 180/n degrees = (31-2) x 180/31 degrees = 168.38 degrees

Exterior angle of a polygon with 31 sides = 180 - Interior Angle = 180 - 168.38 = 11.61 degrees

Inradius = Radius of In-circle = (side length) x cot (Π/31) = 9 x cot 5 = 88.5 units

Circumradius = Radius of Circum-circle = (side length) x cosec (Π/31) = 9 x cosec 5 degrees = 88.96 units

The solution to each equation is:

1. a = 5

2. x = 3

3. y = -1

4. z = 5

5. b = 6

To find the solution, we have to isolate the variable in each equation to one side.

1. 3(2a +5) +4(3a +1) = 109

Expand the brackets:

6a + 15 + 12a + 4 = 109

Collect like terms:

18a + 19 = 109

Subtract 19 from both sides:

18a = 90

Divide both sides by 18:

a = 5

2. 5(2x +3) +3(5x -2) = 84

Expand the brackets:

10x + 15 + 15x - 6 = 84

Collect like terms:

25x + 9 = 84

Subtract 9 from both sides:

25x = 75

Divide both sides of the equation by 25:

x = 3

3. 4(5y +3) -5(3y +1) = 2

Expand the brackets:

20y + 12 - 15y - 5 = 2

Collect like terms:

5y + 7 = 2

Subtract 7 from both sides:

5y = -5

Divide both sides by 5:

y = -1

4. 6(3z -2) +4(z -5)= 78

18z - 12 + 4z - 20 = 78

Collect like terms:

22z - 32 = 78

22z = 110

z = 5

5. 3(6b -1) -7(2b +3)=0​

18b - 3 - 14b - 21 = 0

4b - 24 = 0

4b = 24

Divide both sides by 4:

b = 6

Answer:

Answer: y=mx+b

Step-by-step explanation:

:) Hope this helps!!

Answer + explanation:

Part 1: First, find the area of one triangle using the formula base * height / 2. You have base = 10 and height = 7, so area = 7 * 10 /2 = 70/2 = 35. Since you're finding the combined area of 4, you have to do 35 * 4 = 140.

Part 2: To do this, find the side length of the square. Looking at the picture, you see that all you have to do is 10 + 7 = 17 to find one side. Then, to find the area do 17 * 17 = 289.

Part 3: To find the area of the small square, all you do is area of the large square - combined area of 4 small triangles, so 289 - 140 = 149.

Part 4: a^2 = 7 * 7 = 49. Then, b^2 = 10 * 10 = 100. Adding them together, you get 100 + 49 = 149.

Part 5: Since you already have the a^2 + b^2 part, all you need to do is find what c^2 is. You can see in the picture that c^2 equals the area of the small square, which you found in part 3. c^2 = 149. Then, you have 149 and 149, which are equal so the answer is =.
