The table that represents a function is 1:2, 2:4, 3:6, 4:2.
Option 2 is the correct answer.
Given,
Function table:
1. 1 → 4, 2 → 2, 3 → 4, 2 → 6
2. 1 → 2, 2 → 4, 3 → 6, 4 → 2
3. 2 → 6, 0 → 4, 1 → 6, 2 → 2
4. 2 → 2, 3 → 2, 4 → 6, 3 → 6
We need to find which one is a function.
What is a function?A function has an input and an output.
We can have different inputs and the same output.
Example:
f(x) = x²
x = 1, -1 are the inputs
f(1) = 1
f(-1) = 1
- We see that we have the same output 1 with different inputs 1 and -1.
i.e Many to one
- But we can not have the same inputs and different outputs.
i.e One to many
- We can have one-to-one in a given function.
We have,
1. 1 → 4, 2 → 2, 3 → 4, 2 → 6
Here,
2 → 2 and 2 → 6 = one to many.
We have the same inputs but different outputs which is not possible.
It is not a function.
2. 1 → 2, 2 → 4, 3 → 6, 4 → 2
Here,
1 → 2 and 4 → 2 = many to one
2 → 4 and 3 → 6 = one to one
It is a function.
3. 2 → 6, 0 → 4, 1 → 6, 2 → 2
2 → 6 and 2 → 2 = one to many
This is not possible.
It is not a function.
4. 2 → 2, 3 → 2, 4 → 6, 3 → 6
3 → 2 and 3 → 6 = one to many
This is not possible.
It is not a function.
Thus the table that represents a function is 1:2, 2:4, 3:6, 4:2.
Option 2 is the correct answer.

Question 3
What condition is necessary for AE and BF to be equal? In this situation, what is the relationship between AB and CD? What can you conclude
about parallel lines with regard to the distance between them? Use the word perpendicular in your answer.
Answer:
In order for line AE to equal line BF, m/DFB and m/CEA must both be 90°. When this occurs, line AB does not intersect line EF: the two lines are parallel. line AE and line BF represent the perpendicular distances between line AB and line CD. When the two lines are parallel, the perpendicular distance between them is the same throughout their length.
Step-by-step explanation:
Plato Sample Question
When the two lines are parallel, then the perpendicular distance between them is the same throughout their length.
How are parallel straight lines related?Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.
In order for line AE to equal line BF, Angle DFB and Angle CEA must both be 90°.
When this occurs, line AB does not intersect line EF then the two lines are parallel.
Thus the line AE and line BF represent the perpendicular distances between line AB and line CD.
When the two lines are parallel, then the perpendicular distance between them is the same throughout their length.

Leisha is retiling a hallway in her house with linoleum squares. The area she is tiling measures 60 inches by 132 inches. Each square measures 8.0 inches by 8.0 inches. How many whole tiles should Leisha buy
Answer:
124
Step-by-step explanation:
Multiply 60 by 132. You get 7920.
Now multiply 8 by 8. You get 64.
Divide 7920 by 64. You get 123.75.
SInce the question asks for whole tiles we can't buy 0.75 of a tile, so she could just get one more to fill in that 0.75. That would be 124.

How does light travel so you can see in the dark

Light travels as a wave. But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum—a completely airless space. ... It speeds through the vacuum of space at 186,400 miles (300,000 km) per second.
Tim dug a hole that was 16 1/2 inches deep. He left a pile of dirt next to the at was inches high. Show how you could use subtraction to find the e from the top of the pile of dirt to the bottom of the hole. 8 3/4 Tim dug a hole that hole that was distance from the
Answer: 2 inches
Step-by-step explanation:
14 inches
Step-by-step explanation:
Length of the hole = 16(½) inches
Length of the dirt = 8(¾)inches
The distance between the top of the pile to the bottom of the hole = ?
Since the dirt is beside the hole and not inside the hole, we can find it's length using addition.
Distance from the top to the bottom = length of dirt + length of the hole
Length of dirt = 8×¾ = 6 inches
Length of the hole = 16 × ½ = 8 inches
Distance from the top of the dirt to the bottom of the hole = (6 + 8) inches
Distance from the top of the dirt to the bottom of the hole = 14 inches
Note: the only way we can use subtraction here is if the hole was filled with dirt, what's the distance that's left
Distance left = length of hole - length of dirt
Distance left = 8 - 6 = 2 inches .
Find an ordered pair (x, y) that is a solution to the equation.
5x + y=9
Answer:
Some points are: (1, 4), (0, 9), and (3, -6), just to name a few.
Step-by-step explanation:
We can find out an ordered pair for this equation by plotting the line 5x + y = 9 on a graph. If you graph 5x + y = 9, then we see that the point (1, 4) is a point that the line intersects. Let's substitute that values:
5(1) + 4 = 9
Order of operations, multiply first...
5(1) = 5
Then it becomes...
5 + 4 = 9
We can see that 5 plus 4 actually does equal 9, so the point (1, 4) works. Let's try a different point. We can see the point (0, 9) is another point that the line intersects. Same process for this point too.
5(0) + 9 = 9
Then...
5(0) = 0
0 + 9 = 9
We see that 0 plus 9 ALSO works, but let's try one more time. Another point that works is the point (3, -6) Again, same process.
5(3) + -6 = 9
That is equal to:
5(3) - 6 = 9
Simplify...
5(3) = 15
15 - 6 = 9
15 minus 6 works as well! Any point that the line intersects will be a solution for the equation. I hope this helps!

$5.69≤x
B
$5.69≤x≤$12.33
C
$3.29≤x

The value of the x should be more than or equal to 5.69. Then the correct option is A.
What is inequality?Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is used to compare two statements.
A school is planning a fundraiser with all profits going to charity.
Ticket Sales: 200x − 10x²
Event Cost: 500 + 20x
The amount of profit is found by subtracting the total cost from total ticket sales. A profit of $200 or more.
Event cost − Total sales ≥ Profit
(500 + 20x) − (200x − 10x²) ≥ 200
− 200x + 10x² + 500 + 20x − 200 ≥ 0
10x² + 180x − 700 ≥ 0
10x² − 180x + 700 ≥ 0
x² − 18x + 70 ≥ 0
On simplifying, we have
(x − 5.69) (x − 12.33) ≥ 0
x ≥ 5.69, 12.33
Thus, the value of the x should be more than or equal to 5.69. Then the correct option is A.

The engine of a car has a displacement of 307 cubic inches. What is the displacement in cubic feet? Round your answer to 2 decimal places.
Answer:
5.03 L
Step-by-step explanation:
we know that 1 inch = 2.54 centimeters
(1 inch)3 = (2.54 cm)3
1 in3 = 16.387 cm3
therefore
volume in cm^3 = (volume in in3) x (16.387 cm3/1 in3)
volume in cm3 = (307x 16.387) cm^3
volume in cm3 = 5030.809cm^3
let us convert to liters.
we know that
1 L = 1,000 cm3
volume in L = (volume in cm3) x (1 L/1,000 cm3)
volume in L = (5030.809/1,000) L
volume in L = 5.03 L
307 cubic inche engine displaces 5.03 L
