Explanation:
A relation is any set of (x,y) points usually with some rule tying them together. Though that rule doesn't have to be present. We could simply have a set of points. The set of points we are given is a relation.
A function occurs when we don't repeat the x value. Visually if we had two points stacked on top of each other, then we wouldn't have a function since it fails the vertical line test. A function happens when all x inputs leads to exactly one y output. If we had say { (-4,0), (2,-6), (-4,3) } then this wouldn't be a function since x = -4 repeats itself.
Since none of the x values repeat themselves in our given set, this means we have a function.
Side note: Any function is a relation, but not the other way around.

circumference of a clock with the radius of 16 centimeters?
Answer:
100.5309649cm
Step-by-step explanation:
The formula for the circumference of a circle is:
2πr
if the radius is 16cm, we just need to substitute 16 for r:
2π(16)
= 32π
= 100.5309649cm
You can round this however you like, however I would recommend doing either 3 significant figures either 2 or 3 decimals places :)

Writing Linear Equations
Answer:
1. y=-3x+7
2. y=3/4x+10
3. y=-5x-2
4. y=12x-6
5. y=1/2x+9
Step-by-step explanation:
for numbers 2, 4, 3, and 5 all you have to do is look at the slope they give you. in a linear equation (y=mx+b) the m is the slope. because there is only one equation with the slope they give you, that is the corresponding answer. but for 1, its a bit more complicated. because they give you a point you have to plug the x value into your equation. for exaple for 1. they give you 0 as the x value so you plug it into one of the equations. and if that equation gives you 7 as the y, then you have your answer.
The set of all numbers less than or equal to -1.
Answer:
anything before -1 is lower than -1. -1 = -1
Step-by-step explanation:
-10, -9, -8, -7, -6, -5, -4, -3, -2 etc. are in a sense before -1 on a time line and they are all less than -1
Set B represents the set of all the natural numbers less than or equal to -1
[tex]\rm B=\{-\infty ...........-4,-3,-2,-1\}[/tex]
if we include all the numbers the range of set includes every number from
[tex]\rm -\infty \; to -1[/tex] so the set is represented by K
[tex]\rm K = \{ -\infty ,.....-1\}[/tex]
In Mathematics a set is a collection of objects/elements that are constrained by some particular condition.
Let us consider a situation where "S" is the set and the elements are represented by "x"
A set is always denoted in curly braces. Expression (1) represents the set
[tex]\rm S =[/tex] { [tex]\rm x_1.x_2,x_3, x_4,x_5........x_n[/tex]}...........(1)
Set S has elements that are represented as [tex]\rm x_1[/tex][tex]\rm\\where \; i \; represents\; the\; index\; of \; the \; element\\n = number\; of \; elements \; in \; the \; set \; x[/tex]
The set of all the natural numbers less than or equal to -1 is the set of all the negative integers including -1.
So let us say B represents the set of all the natural numbers less than or equal to -1 . Then we can write it as follows
[tex]\rm B=\{-\infty ...........-4,-3,-2,-1\}[/tex]
Set B represents the set of all the natural numbers less than or equal to -1
if we include all the numbers the range of set includes every number from
[tex]\rm -\infty \; to -1[/tex] so the set becomes
[tex]\rm K = \{ -\infty ,.....-1\}[/tex]

1. What is the difference between a line and a line segment?
A. A line is a figure formed by two opposite rays with a shared endpoint, a line segment is a part of
a line that extends forever in one direction.
B. A line is a specific location that is represented by a dot, a line segment is a specific location
represented by two dots.
C. Aline is a portion of a line consisting of two points and all the points between them, and a line
segment is a figure formed by two opposite rays.
D. Aline is a figure formed by two opposite rays and a shared endpoint, and a line segment is a
portion of a line consisting of two points and all the points between them.
Explanation:
Basically a line goes on forever in both directions. A ray only goes off forever in one direction. If we glue together two rays that point in complete opposite directions (eg 1 points north, the other points south) then we form a line.
A line segment is a piece of a line. It doesn't go on forever in either direction. It has 2 endpoints and has a set fixed length. If you know the coordinates of each endpoint, you can use the distance formula to find that length.

A. 294 cu. units
B. 1008 cu. units
C. 196 cu. units
D. 112 cu. units
Answer:
C) 196 cu. units
Step-by-step explanation:
Volume = lwh/3
= 7 x 7 x 12 / 3
= 588/3
= 196
The volume of a square pyramid is 196 cubic units.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
From the given figure, side of square base is 7 units and height is 12 units.
We know that, the volume of square based pyramid =a²h/3.
Now, volume of a pyramid = 1/3 ×7²×12
= 49×4
= 196 cubic units
Therefore, the volume of a square pyramid is 196 cubic units.

Why do you think y= ax+b is called a linear equation
Please help
Answer:
Y=mx+b Is a linear equasion because if you plot the x and y on a graph it always shows a straight line.
Step-by-step explanation:
For example, y=7x+9,
When x is 1 y is 16, and
when x is 2 y is 23.
When you put those two points on a graph and connect the dots with a ruler, you get a straight line, and you will automatically find that when x is 3 y is 30.

Hey there!
Reason:
The power of the term is one.It can be graphed in a at. line on graph.You can simply define linear equation as the equation which has two variables with 1 exponent.

3. Mrs. Galicia started a savings account for her family and started it with an initial deposit of $1600. The account earns 3.75% interest compounded quarterly.
(a) Write an equation to represent the anount of money in the account as a function of time in years.
(b) How much money will be present in the account in 5 years. *please show plug in step*
Hey there!
--› Initial deposit: 1600
--› rate = 3.75%
a) First, convert R as a percent to r as a decimal
r = R/100
r = 3.75/100
r = 0.0375 rate per year,
Substitute into formula
= A = P(1 + r/n)nt
A = P(1 + 0.0375/4)^4t
A = 1,600.00(1 + 0.009375)^4t
b)
A = 1,600.00(1 + 0.009375)^4t
A = 1,600.00(1 + 0.009375)^4(5)
A = 1,600.00(1 + 0.009375)^(20)
A = $1,928.28
The amount of money that will be present in the account in 5 years is P(5) = $1923.36
Exponential equationsThe standard exponential equations is expressed as:
p(t) = p0(1+r)^t
where:
Po is the initial deposit = $1600Rate "r" =3.75% = 0.0375time "t" = 5 yearsSubstitute
P(t) =1600(1+ 0.0375)^t
P(t) = 1600 (1.0375)^t
Hence the equation to represent the aount of money in the account as a function of time in years is P(t) = 1600 (1.0375)^t
If t =5 years
P(t) = 1600 (1.0375)^t
P(t) = 1600 (1.0375)^5
P(5) = $1923.36
Hence the amount of money that will be present in the account in 5 years is P(5) = $1923.36
