Determine if the following representations or functions or not? Explain your reasoning.
The three relations given all represent functions because each has exactly one y-value that corresponds to each x-value.
What Relation can be Defined as a Function?A relation can be defined as a function if the x-values (input/domain element) each has exactly one y-value (output value/range element) that is related to or it corresponds to.
A function can have two x-values that have the same y-value but cannot have two y-values that corresponds to one x-value.
In the first relation showing a graph, each x-value on the graph has exactly one y-value it corresponds to. Therefore, it is a function.
In the second relation that is represented by the set of ordered pairs, every x-value also have only one y-value it is related to. Therefore, it represents a function.
The third function given shows a table of values of a relation that has exactly only one y-value that is assigned or related to each x-value. This also is a relation that represents a function.
Therefore, all three relations represent functions.

A shoe store buys packs of socks wholesale for $5 each and marks them up by 40%. The store decides to discount the packs of socks by 40%. Is the discounted price $5? OA) yes: The packs of socks are marked up to $7 and then discounted to $5. OB) yes; The packs of socks are marked up to $9 and then discounted to $5. OC) no: The packs of socks are marked up to $7 and then discounted to $4.20. OD) no, The packs of socks are marked up to $5.20 and then discounted to $4.99.
Answer:
C) no: The packs of socks are marked up to $7 and then discounted to $4.20
Step-by-step explanation:
You want to know the price of a $5 pair of socks after markup by 40%, and again after that price is marked down 40%.
Marked-up priceWhen the $5 cost is marked up by 40%, the resulting price is ...
$5 + 0.40×5 = $5 +2 = $7.
The socks are marked up to $7.
Marked-down priceWhen the $7 price is marked down by 40%, the resulting price is ...
$7 - 0.40×7 = $7.00 -2.80 = $4.20
The socks are discounted to $4.20.

example of an event which has a probability of 0. Explain why the probability equals 0.
The example of an event which has a probability of 0 is probability of getting number 7 when you throw a die once. The probability of this event is zero because it will not occur.
The probability is the branch of mathematics that shows the occurrence of the random event. The value of the probability varies from 0 to 1.
The equation of the probability is
Probability = Number of favorable outcomes / Total number of outcomes
The probability of getting number number 7 when you throw a die once is zero. Because when you throw a die the possible outcomes are 1, 2, 3, 4, 5 and 6. We wont get number 7. Therefore the probability is zero
Hence, the example of an event which has a probability of 0 is probability of getting number 7 when you throw a die once. The probability of this event is zero because it will not occur.

a. What is the assessed value?
b. What is the yearly real estate tax?
a.) The Assessed value is $43,830
b.) Annual Tax is $2,848.95
Define marked price
'Marked price' is the general price of the thing without any discount. 'discount' is a percentage of the marked price.
Given,
Assessment rate = 45%
Tax rate is $65 per $ 1000 of assessed value
Marked value = $97,400
a.)
To obtain assessed value,
calculate the 45% of $97,400 like that
45/100 = x/97,400
cross multiply the ratios
100x = 45 * 97,400
x = (45 * 97,400) / 100
x = 45 * 974
x = 43,830
Hence,the Assessed value is $43,830
b.)
Find yearly real estate tax,
Assessed value = $43,830
Tax rate is = 65 / 1000 of assessed value

Step-by-step explanation: The reason why is because in the question it said he is already carrying a 20 pound chair. It then say he can carry some boxes that weigh 5 pounds each. The word each is your keyword. With that you can replace the x variable with some single digit numbers. But you also need to make sure your total is less than or equal to 60 pounds. You would pick the less than or equal to sign since he can only carry 60 pounds or less.

Total outcome is 50 [because the number produced by the machine is from 1 to 50]
Question a:
Multiple of 10 are 10, 20, 30, 40, 50
There are five possible outcomes for multiple of 10
P(Multiple of 10) = 5/50 = 1/10
Question b:
Number 1 to 50 will be all the outcomes that are not 100
There are 50 possible outcomes
P(not 100) = 50/50 = 1
Question c:
Multiple of 4 that are less than 50 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48
There are 12 possible outcomes for multiple of 4
We want 'not multiple of 4' so we need to do 50 - 12 = 38 outcomes
P(not a multiple of 4) = 38/50 = 19/25

The set S:{ - 2 , - 3 } will make the inequality 2p - 8 < 5p + 4 true
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
The set S : { - 2 , - 3 , - 4 , - 5 }
The inequality relation is 2p - 8 < 5p + 4
Now , substituting the value from set S in the inequality , we get

2p − 8 < 5p + 4
2(-2) − 8 < 5(-2) + 4
-4 − 8 < -10 + 4
-12 < -6 TRUE

Which expressions can be factored using the difference of squares identity?
The expression, for example, x²- 49 may be factored as (x+7)(x-7). can be factored in using the difference of squares identity.
What is the "Difference of Squares" identity?The difference of the square's identity is shown below:
(a+b)(a-b) = a² -b²
When an expression can be seen as the difference of two perfect squares, i.e. a² -b², we can factor it as (a+b) (a-b).
For example, x²- 49 may be factored as (x+7)(x-7).
This approach is based on the pattern (a+b)(a-b) = a² -b², which may be validated by extending the parenthesis in (a+b)(a-b).

Using substitution method, the best initial step in solving the equation is solve the first equation for x.
How to solve equation by substitution method?The equation can be solved by substitution method as follows:
2x + 3y = -12
6x + y = 18
Hence, let's make y the subject of the formula in equation(ii)
6x + y = 18
y = -6x + 18
We have to substitute the value of y in equation(i)
2x + 3y = -12
2x + 3(-6x + 18) = -12
2x - 18x + 54 = -12
- 16x + 54 = -12
-16x = - 12 - 54
- 16x = -66
x = 66 / 16
x = 33 / 8
Therefore,
6(33 / 8) + y = 18

The side of square is 216 units and side of cube is 36 units.
According to question we have given that Sally has a cube of some length in units. Let the length of side of cube is S units .
As we know , Area of cube = 6 (side)²= 6S² square units.
Volume of cube = (side)³ = S³ cubic units
Then, as given area in square units of cube = 1/6 of volume of cube in cubic units . That is 6S²= 1/6 S³ => S = 36 units
Area of cube with side 36 units = 6×36²=46656 square units
Volume of cube with side 36 units = 36 ³ cubic units
So, the side of cube is 36 units.
Also, the number of square units in area of Square = number of cubic units in volume of cube

What is rate of expansion of solid ?For physics, The term "thermal expansion" refers to a material's change in length, width, height, or volume when its temperature is raised or lowered. Solids exhibit particularly noticeable thermal expansion due to their closely packed atoms. There are numerous uses for thermal expansion of solids in daily life.
A solid's atoms vibrate more quickly around their fixed positions when it is heated. As a result, there is little relative growth in the size of solids during heating. In order to prevent buckling when exposed to heat from the sun, metal train tracks feature tiny gaps.
CalculationL = length of a side
A = L2
dA/dt = 2L dL/dt
dL/dt = 8 cm/s
A = 81 cm2 ⇒ L = √A = √81 cm = 9 cm
