Answer:
A function is a relation that maps elements from one set (the domain, the set of the inputs) into elements from another set (the range, the set of the outputs). Such that each element of the domain can be mapped into only one element of the range.
Now let's analyze the given relations.
1)
Here we can see that the inputs are -3, -1, 1, and 2.
Then the domain (the set of the inputs) is:
D = {-3, -1, 1, 2}
And we can see that the outputs are 0, 2, and 5.
Then the range is:
R = {0, 2, 5}
We also can see that each input is being mapped into only one output, then this relation is a function.
2) In this case the inputs are -2, -3, and 5.
Then the domain is:
D = {-2, -3, 5}
And the outputs are 6, 7, 8
Then the range is:
R = {6, 7, 8}
And we can see that each input is mapped into only one output, then this relation is a function.
3) In this case we can see that the inputs are -4, -2, and 0
Then the domain is:
D = {-4, -2, 0}
And we can see that the outputs are -2, -1, 3, and 4.
Then the range is:
R = {-2, -1, 3, 4}
In this case, we can see that the input -4 is being mapped into two different outputs (3 and -1)
Then this relation is not a function.

Two angles are supplementary. One angle is five times larger than the other. What are the measures of the two angles.
Answers
Answer:
30 degrees ; 150 degrees
Step-by-step explanation:
1) rememeber that two supplementary angles have their sum equals to 180 degrees
2) write an equation with the given information
x + 5x = 180
2) solve the equation
- added up the terms with x
6x = 180
- divide the two members by 6
x = 30
- find the second angle by multiplying 30 by 5

2) y axis is the line that goes vertically
3) origin is (0,0)
4) A is the dot that is height is the middle. B is the highest dot. C is the lowest dot
5) (4,6)
6) (2,9)
7) (0,4)
8) the correct ordered pair is (7,3) because it is (x,y) and allie switched between the two
1. The X axis is the line going left and right
2. The Y axis is the line going up and down
3. The origin is the point where the X and Y axis meet; (0,0); by the 0
4. The points will be written as A, B, C. This is going from left to right. So the first box on the coordinate plane furthest to the left with be labeled with A. Then the second box furthest from the left; the middle box; will be labeled with B. Then the last box will be labeled C
5. (4,6)
6. (2,9)
7. (0,4)
8. When Allie identified the point, she mixed the X and Y coordinates. To identify a point you first want to find the point following the X axis. Then do the same with the Y axis. After doing this you should have 2 numbers, in which are 3 and 7. Now when writing the coordinates, the X axis ALWAYS comes first. So it should look like (7,3)

A building 220 feet casts a 100 foot long shadow. If a person stands at the end of the shadow and looks up to the top of the building, what is the angle of the personas eyes to the top of the building? 62.14 65.56 64.95 27.86
Answers
Answer:
65.56°
Step-by-step explanation:
= We solve the above question using the Trigonometric function of Tangent
tan θ = Opposite/Adjacent
Opposite = 220 feet = Height of the building
Adjacent = 100 feet = Length of the shadow
Hence,
tan θ = 220/100
tan θ = 2.2
= arctan(2.2)
= 65.55604522°
Approximately = 65.56°

Answers
Answer:
D. 40 m2
Step-by-step explanation:
The area of a rectangle is its length multiplied by its width.
length * width = Area
5 * 8 = 40
Answer:
[tex]\Huge\boxed{D.40m^2}[/tex]
Step-by-step explanation:
area of a rectangle = width times length
given width = 8 meters

Answer:
66 baskets
Step-by-step explanation:
So, this is a simple math equation if you break it down step by step. Let's see what we know from the question.
First Day = Already 10 baskets.
Every day = +4 more baskets.
Meets her goal after 2 weeks/14 days
**Questions may use different units to try to trick you, such as weeks and days! But, they are the same.**
Okay, so now we have gathered the information we know, now lets make the math equation. First we need to make the variables. Let's let G equal how many baskets she made on day 14.
G = 10+(14x4)
G = 10+(56)
G = 66
So, she made 66 on the 14th day
A trapezoid has a height of 3 meters, a base length of 8 meters, and an area of 30 square meters. What is the length of the base?
Answers
Answer:
Length of the second base will be 12 meters.
Step-by-step explanation:
Area of a trapezoid is given by the formula,
Area = [tex]\frac{1}{2}(b_1+b_2)h[/tex]
Here, b₁ and b₂ are the bases of the trapezoid and 'h' is the vertical distance between the bases.
By substituting the values in the formula,
[tex]30=\frac{1}{2}(8+b_2)3[/tex]
[tex]60=3(8+b_2)[/tex]
[tex]20=8+b_2[/tex]
[tex]b_2=12[/tex]
Therefore, length of the second base will be 12 meters.
