Relate a vertical line test to understanding functions.
a.
Each horizontal line drawn through the graph will intersect a function in only one location
c.
Each vertical line drawn through the graph will intersect a relation in only one location
b.
Each vertical line drawn through the graph will intersect a function in many locations
d.
Each vertical line drawn through the graph will intersect a function in only one location
Please select the best answer from the choices provided
A
B
C
D
Answer: Choice D
Each vertical line drawn through the graph will intersect a function in only one location.
This is another way of saying that for any input x, there is exactly one output y. If you had a vertical line cross through a curve at multiple points, then this would mean that x input produces multiple y outputs, and we won't have a function. A function must produce one output whatever the input is (assuming the input is in the domain of course).

Answer:
1/36
Step-by-step explanation:
notice the first equation is the second equation squared.
For instance, look at the numerator: a squared is a^2
Look at the denominator: a^2 squared is a^4 and so on.
So if the second equation is 1/6, then you need to square it to have it equal the second equation: (1/6)^2 = 1/36
Shirts are on sale for 20%.You buy 2 of them. As you pay, the cashier says, “20% off of each shirt means 40%off the total price.” Do you agree or disagree? Please explain thoroughly.

Explain why all triangles have at least two acute angles.
If two angle measures of a triangle were each greater than or equal to
(90, 180) the sum of the three angle measures would be (greater than 90, greater than 180)
which is not possible.
Answer: all 3 angle measures have to equal 180 degrees. So if two of them are more than 90 degrees, the sum of the angles would be greater than 180.

Step-by-step explanation:
Part A: The sun produces 3.9 ⋅ 1033 ergs of radiant energy per second. How many ergs of radiant energy does the sun produce in 1.55 ⋅ 107 seconds? (5 points)
Part B: Which is the more reasonable measurement of the diameter of a human hair:
1.8 ⋅ 10−2 mm or 1.8 ⋅ 102 mm? Justify your answer. (5 points)
Using the multiplication operation, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]
Eggs produced per second = [tex]3.9 \times 10^{33} [/tex] Number of seconds = [tex]1.55 \times 10^{7} [/tex]Total number of ergs produced can be calculated thus :
Ergs per second × number of seconds[tex]3.9 \times 10^{33} \times 1.55 \times 10^{7} = 6.045 \times 10^{33+7} = 6.045 \times 10^{40} \: ergs [/tex]
Therefore, the Number of ergs produced in [tex]1.55 \times 10^{7} [/tex] is [tex] 6.045 \times 10^{40} \: ergs [/tex]
B.)
Due to the very small measure of the diameter of the human hair, a measure of [tex]1.8 \times 10^{2} mm[/tex] would be too large, Hence, the value [tex]1.8 \times 10^{-2} mm[/tex] would be more appropriate

I don´t know about scale factor so I will also say 5
Answers:
Scale factor = 1/5B = 5===========================================
Explanation:
Look at the left most sides of each figure. Dividing the smaller side over the larger leads to 7/35 = (1*7)/(5*7) = 1/5. This is the scale factor. It means the blue figure's side lengths are 1/5th of the orange figure's corresponding side lengths.
So that explains why your teacher put A = 20(1/5) = 4
Multiplying the orange side lengths by the scale factor gets you the blue side lengths.
Now focus your attention on the far right most side lengths of 25 and B
We can see that B = 25(1/5) = 5 feet.
A case of 11 dozen place mats costs $23.76. What is the cost for one place mat?
$0.02
$0.18
$0.22
$2.16
Answer:
$2.16
Step-by-step explanation:
There are 11 mats. The question is asking for the price of 1 mat. You know that 11 mats cost $23.76. You devide $23.76 with the number of mats which is 7 and you get $2.16.

steps to the answer of 1/3(n+6)=−10?
Answer: n=−36
Step-by-step explanation: When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
n+36
———— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
n+36 = 0
Solve : n+36 = 0
Subtract 36 from both sides of the equation :
n = -36

Answer: The answer is x=4
Step-by-step explanation:
1/2x+15=5+3x
subtract 5 from both sides and now you have 1/2x+10=3x
Subtract 1/2x from both sides, leaving you with 10=2.5x
then divide 2.5 from both sides. That leaves 4=x or x=4
Erion plans to tile the floor of his kitchen. The kitchen is 11 feet by 15 feet. The tiles he will be using are square, measuring 8 inches on each side, and are sold in boxes that contain enough tile to cover 25 square feet. How many boxes of tiles must he order to complete the job?
Answer:
First, find the area for the kitchen floor: 16.5*15=247.5 squared feet
Then find the area for one tile: 0.5*0.5=0.25 squared feet
Finally, divide the mayor area between the minor: 247.5/0.25= 990 tiles.
Also you can do it in this another way:
First, divide length of the kitchen floor between the length of one tile: 16.5/0.5=33
Then, do the same for the height: 15/0.5=30
Finally multyply both results: 33*30= 990 tiles.
Step-by-step explanation:
or just 990
