does the graph below represent a function? why or why not?
Answer:
Step-by-step explanation:
The coordinate plane is also called a Cartesian Plane. Function. A function is a relationship where there is only one output for every input. In other words, for every value of x, there is only one value for y.
Does this help?
Answer:
It is NOT a function.
Step-by-step explanation:
It does not pass the vertical line test. A vertical line can touch the graph in more than one point.
To be a function, every x can have only one y value. On this graph almost every single x has two y's. For example when x is -6, the y is 2 and also 8. Not a function.

On Monday a builder built 5/9 of a wall. On Tuesday he added the last 180 bricks to finish the wall. How many bricks are there in the wall?
Answer:
405
Step-by-step explanation:
So he built 5/9 of the wall, than added the extra 180 bricks to finish the wall.
so 5/9 + 180 = 9/9
so 180 = 4/9 Because 5/9 + 4/9 = 9/9
So to figure out how many bricks are in the wall we want to know what 1/9 of bricks equals and to work this out we need to divide 180 by 4
which equals 45.
Now we know that 1/9 = 45
so now to figure out what 9/9 is just multiply 45 by 9 which equals 405
Answer:
405 bricks in total
Step-by-step explanation:
1 - 5/9 = 4/9
So 4/9 of the bricks are remaining, and "the last 180 bricks" is equal to 4/9
Using ratio method:
4/9 : 180
5/9 : x
x = 180 × 5/9 ÷ 4/9
x = 225
So 180 + 225 = 405 bricks in total

The marked price of a watch is 30% above the cost price. When it is sold allowing 20% discount on it, there is a gain of Rs 150. Find the marked price and the cost price of them.
Answer:
Marked price: Rs. 4875
Cost price: Rs. 3750
Explanation:
(i) Cost price: 100%
(ii) Marked price: (100% + 30%) = 130%
(i) Let the cost price be p
(ii) Marked price: 130% × p = 1.3p
Given, 20% discount then sold at 80%
Discount price: (130% × 80%) × p = 1.04p - discounted price
Gain price: 1.04p - p = 0.04p
Cost price:
0.04p = 150
p = 150/0.04 = 3750 ← This is the cost price.
Marked price:
1.3p = 1.3(3750) = Rs. 4875
The lengths of two sides of a triangle are 5 inches and 8 inches. Which of the following lengths could be the length of the third side of the triangle? Select all that apply.
By using the triangular inequality, we conclude that the other side must measure more than 3 inches and less than 13 inches.
Which values could the length of the third side take?
Remember that the triangular inequality says that the sum of any two sides on a triangle is larger than the other side of the triangle.
If we define the missing side of the triangle as x, then we must have:
5 + x > 8
8 + x > 5
8 + 5 > x
From the third inequality we get the upper bound:
13 > x.
From the first inequality we get the lower bound:
x > 8 - 5 = 3
Then:
3 < x < 13
This means that the other side of the triangle must measure more than 3 inches and less than 13 inches.

A high school student named David Merrell did a study of how music affects the ability of rats to run a maze. He trained 71 rats to run a maze. Next he randomly divided the rats to three groups. Each group had 23 or 24 rats. For the next month, one group of rats listened all day to heavy metal music by the group Anthrax. One group listened all day to Mozart. One group never heard music. The rats ran the same maze three times a week for a month. The response variable is the time in seconds to complete the maze. By the end of the month he compared the average run time for each treatment group to the average run time for the control group. The Anthrax group was much slower at running the maze. The Mozart group was much faster. The differences are statistically significant at the 1% level. Run times are not heavily skewed in any group. What conclusion can we draw from these results
Step-by-step explanation:
Heavy Metal "music" impacts negatively the long term memory, if at least the ability to access it.
while harmonic music has no blocking effect or maybe even strengthens the long term memory and the ability to access it.
here 3 remarks.
first 2 scientifically from psychology : memory works mostly associative. that means brains do not store absolute information like a digital computer, but always in combination and association with other pieces of information. if there is nothing else to remember (like a more or less random pattern of sound effects for that the brain cannot find a rule or concept for), there are no associations with presented pieces of information, and the storage and access to it is much harder and restricted.
and - loud crashing and seemingly random noise triggers the panic mode in our brains. and panic is the mode favoring pure instinct and suppressing cognitive functions.
and finally, personally, it just confirms what I literally feel when listening to such music : it destroys at that moment any ability to keep a straight thought, prolonged exposure gives me the feeling that something gets broken inside my brain and thought processes.
I suspect that this is exactly the feeling that the fans of this kind of music are after (kind of like most drugs), but I am not surprised that there actually is something broken in the brain (again, as with drugs).
The radius of a circle is 13 ft. Find its area in terms of pi.
Answer:
The area of the circle would be 530.93 sq ft.
Step-by-step explanation:
The formula is A = π r². We know that the radius or r is 13, meaning that the new equation is A = π 13². 13 to the second power is 169 meaning that the formula would now be A = π(169). 169 times π is 590.93 getting you your answer. I hope this helped! :)

The angle of elevation of the sun relative to an observer standing at the tip of the shadow is 16.9°.
What is trigonometry?The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
Given that:-
A cell phone tower that is 70 meters tall is built on level ground and casts a shadow 230 meters long at a particular moment.The angle of elevation will be calculated by applying trigonometric property in the triangle given below;-
[tex]tan\theta=\dfrac{P}{B}[/tex]
[tex]tan\theta=\dfrac{70}{230}[/tex]

The volume of the cone below is 700 cm³. Calculate the height of the cone. If your answer is a decimal, give it to 1 d.p. 8 cm
Answer:
10.4 cm
Step-by-step explanation:
Formula used :
Volume (cone) = 1/3πr²h
=============================================================
Given :
⇒ Volume = 700 cm³
⇒ Radius = 8 cm
===========================================================
Solving :
⇒ 700 = 1/3 × π × 8² × h
⇒ 700 = 64π/3 × h
⇒ h = 700 × 3 / 64π
⇒ h = 2100/64π
⇒ h = 10.4 cm (rounded to 1 decimal place)

What is a Ratio?A ratio shows us the number of times a number contains another number.
The ratio of the ages of Mandy and Sandy is 2:5. Therefore, the ratio will be,
M/S = 2/5
M = 2S/5
After 8 years, their ages will be in the ratio 1:2, therefore,
(M+8)/(S+8) = 1/2
2M + 16 = S + 8
2M - S = -16 + 8
Substitute the value of M,
2(2S/5) - S = -8
-0.2S = -8
S = 40
Now, if we substitute the value of S in the first ratio,
M/S = 2/5
M/40 = 2/5
M = 16
Now, if we take the difference in their ages the difference will be 24(40-16).
Since the difference is 24, we can conclude that Caitlin is right.
