13.a) sketch a graph of a function that has a set of integers as its domain and all integers less than 5 as its range. b) sketch a graph of a relation that is not a function and that has the set of real numbers les then or equal to 10 as its domain and all real numbers greater than -5 as its range
The required function that has a set of integers as its domain and all integers less than 5 as its range is y = -|x| + 5
Given that,
To draw a sketch of a graph of a function that has a set of integers as its domain and all integers less than 5 as its range.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
In order to draw the graph of a function that has a set of integers as its domain and all integers less than 5 as its range.
We add
y = -|x|
For the domain to be all integers
Now, adding 5
Y = -|x| + 5
Thus, the required function that has a set of integers as its domain and all integers less than 5 as its range is y = -|x| + 5.

Among a town’s registered voters, there are 34% Democrats and 25% Republicans. The rest are Independents. If there are 1517 registered Independent voters in this town, how many total registered voters are there?
The total number of registered voters is 3700.
What is the total number of registered voters?
Percentage can be described as the fraction of a number expressed as an amount out of 100. Percentage is a measure of frequency. The sign that is used to represent percentages is %.
The first step is to determine the percentage of independent voters.
Percentage of independent voters : 100 - (percent of democrats + percent of republicans)
100 - (34% + 25%)
100- 59% = 41%
Total number of voters = number of independent voters / percentage of independent voters
1517 / 41%
1517 / 0.41 = 3,700

Mila buys cookies and oranges at the store.
She pays a total of $22.39.
She pays a total of $6.58 for the cookies.
She buys 3 bags of oranges that each cost the same amount.
Write and solve an equation which can be used to determine xx, how much each bag of oranges costs.
The equation that can be used to represent the cost of oranges and cookies is; 6.58 + 3x = 22.39. Thus, the cost of each bag of orange is x = $5.27
How to Solve Algebra Word Problems?We are given;
Total Amount paid by Mila = $22.39.
Amount Mila paid for cookies = $6.58
Now, we are told that she also buys three bags of oranges. Now, if we denote the cost of each bag of orange to be x, then it means that;
Cost of 3 bags of oranges = $3x
Thus, we can write the equation to represent the cost of oranges and cookies as;
6.58 + 3x = 22.39
Subtract 6.58 from both sides to get;
3x = 22.39 - 6.58
3x = 15.81
x = 15.81/3
x = 5.27
Thus, the cost of each bag of orange is x = $5.27

Using the definition of the absolute value function, we have that, for item b, the function and breaking points are given as follows:
y = -3x - 1, x < -0.5.y = x + 1, x ≥ -0.5.The function breaks at x = -0.5.
For item c, we have that:
y = -2x - 2, x < -3.y = 4, -3 ≤ x ≤ 0.5.y = 4x + 2, x > 0.5.The function breaks x = -3 and x = 0.5.

What is the absolute value function?The absolute value function is defined by the following piecewise rule, depending on the input of the function:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.

Determine whether the regular polygon will tessellate in the plane. Write yes or no. Explain.
16 -gon
No, he regular polygon 16 -gon will not tessellate in the plane.
What is tessellation?A tessellation or tiling is the seamless application of one or more geometric shapes, known as tiles, to a surface, frequently a plane. Tessellation in mathematics can be expanded to include other geometries and higher dimensions.
A tiling constructed of materials like cemented ceramic hexagons or squares is referred to as a real-world tessellation. Such tilings may be ornamental designs or serve practical purposes such providing long-lasting and water-resistant pavement, floor, or wall coverings.
Tessellations were historically employed in Islamic art, such as the Moroccan architecture and the ornamental geometric tiling of the Alhambra palace. They were also used in Ancient Rome.
Regular polygons tessellate if their interior angles divide by 360° evenly or if the total of their interior angles is a factor of 360°. A tessellation is a pattern made of identical forms that fit together seamlessly.
So lets find out how pentagon won't tessellate.
First we find the measure of the interior angles of 16 -gon,
[tex]\frac{2520\°}{16} = 157.5\°[/tex]
Now divide the interior angle by 360°
[tex]\frac{360\°}{157.5\°} = 2.28[/tex]
Hence, the measure of the interior angle does not divide by 360°.
Therefore, we conclude that the regular polygon 16- gon will not tessellate in the plane.

Step-by-step explanation:
Each obstacle course has 2 jump rope stations and 2 pogo stick stations.
There are 4 obstacle courses
So total number of jump rope stations = 4 x 2 = 8
Each jump rope station requires x jump ropes
So total number of jump ropes needed = 8x
Each pogo stick stations. requires y pogo sticks
So total number of pogo sticks needed = 8y
Expression to represent how many jump ropes and pogo sticks Mr. Vincent needs in all is

The common sparrow has a wingspan of 9 to 15 centimeters. Which inequality matches the wingspan of the common sparrow?
The inequality which matches the wingspan of the common sparrow is :
9 ≤ x ≤ 15.
What is inequality and how can we frame one?
Inequalities are the equations in which two non equal expressions are compared using the mathematical relations such as ≤(less than or equal to ), ≥ (more than or equal to ), < (less than ) , >( more than).
Given that the common sparrow has a wingspan of 9 to 15 centimeters.
Let the wingspan of sparrow be x then given that x is more than or equal to 9 which gives an inequality : x ≥ 9 ....(1)
Also it is given that wingspan, x is not more than 15 centimeters which means x is less than or equal to 15 and this gives an inequality: x ≤ 15 ....(2)
Combining (1) and (2), we get:

What is the AP sequence (arithmetic progression)?In Arithmetic Progression (AP), the distinction between two arithmetical orders is a constant. It is also known as Arithmetic Sequence.
Then we'd run into some important words in AP, such as:
The first term (a)Common difference (d)Term nth (an)The total of first n terms (Sn)The AP can also be described using common distinctions, as shown below.
The following is the way to determine an AP's n-th term: an = a + (n − 1) × dThe formula for arithmetic progression sum is as follows: Sn = n/2[2a + (n − 1) × d].Common difference 'd' is d = a2 - a1 = a3 - a2 = a4 - a3 = ...... = an - an-1.Now, as per the question;
Consider any sequence. Let's say 2, 3, 5, 6..
Let's consider the first term is'a₁' = 2.
Let's consider 'a₂' = 3 is the second term.
Let's consider the third term is 'a₃' = 5.
Let's consider the fourth term be 'a₄' = 6
d₁ = a₂ - a₁
Substitute the values;
d₁ = 3 - 2 = 1 ........(equation 1)
Now take the other set;
d₂ = a₃ - a₂
d₂ = 5 - 3 = 2 .......(equation 2)
From the two equations 1 and 2. it is clear that the value of both common difference d₁ is not equal to d₂. Thus, the sequence considered is not in AP.
Therefore, the considered sequence 2, 3, 5, 6.. is not in AP.

Write the equation of the line in slope-intercept form.
y-5x=16
The equation of the line in slope-intercept form is y = 5x + 16 .
The equation of a line in slope-intercept form can be written as follows,
y = mx + c equation 1
m in the above equation represents slope of the line and c represents the intercept.
The given equation is y - 5x = 16 .
To get the equation of the line in slope-intercept form we need to convert the given equation in the format of equation of a straight line i.e., equation1. So, now we will rearrange the given equation as
y - 5x = 16
On adding 5x on both sides in above equation, we will get
y = 5x + 16 equation 2
On equating equation 1 and equation 2, we will get
Slope of the line = m = 5
Intercept = c = 16
The equation of the line in slope-intercept form is y = 5x + 16 .
