No the given relation is not a function because for one input we are getting two different values of output which negates the definition of the function.
A relation is said to be a function when each and every element of domain has a unique and distinct image means we will get only one output per input.So
statement 1: No, because for each input there is not exactly one output . This is true.statement 2: No, because for each output there is not exactly one input. This is false.statement 3:Yes, because for each input there is exactly one output .This is false.statement 4:Yes, because for each output there is exactly one input.This is also false.Hence the given relation is not a function.

The given relation is not a function because for each input (x-value), there is not exactly one output (y-value).
In a function, each input (x-value) should have only one corresponding output (y-value). However, in this relation, the input value of 1 has two different output values: -2 and 3. Therefore, it violates the definition of a function.
To illustrate this, let's look at the points (-2, 0), (1, -2), and (1, 3). The x-value of 1 appears twice in the relation, but it has two different y-values associated with it. This means that for the input value of 1, there is not exactly one output value, which is why the given relation is not a function.
In conclusion, the relation is not a function because for each input there is not exactly one output.

Talia runs and swims every day. She runs for 0.75 hours per day. She swims for s hours per day. Over 4 days, she runs and swims for a total of 5 hours.
Which equation can be used to find the number of hours Talia swims per day?
Y'all just need to pick which equation is the right one in the choices
Answers
Answer:
C: 4 (0.75 + s) = 5
Step-by-step explanation:
You're Welcome !
The number of hours Talia swims per day is 0.50 hours.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Talia runs and swims every day. She runs for 0.75 hours per day. She swims for s hours per day.
Time taken in a day to run and swim is 0.75+s
Over 4 days, she runs and swims for a total of 5 hours.
So, the equation is 4(0.75+s)=5
0.75+s=5/4
0.75+s=1.25
s=1.25-0.75
s=0.50
Therefore, the number of hours Talia swims per day is 0.50 hours.

This is the graph of f(x) = x+A/x+B. The grid lines in the graph are one unit apart. What is the value of A/B
Answers
The value of A/B is given as follows:
A/B = -2.
What are the asymptotes of a function f(x)?The vertical asymptotes are the values of x which are outside the domain, which in a fraction are the zeroes of the denominator.The horizontal asymptote is the value of f(x) as x goes to infinity, as long as this value is different of infinity.From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:
B = -1 -> as x + B = 0 -> x = -B = -1.
When x = 0, y = -2, hence the value of A is obtained as follows:
A/-1 = -2
A = 2.
Then the division is given as follows:
A/B = 2/-1 = -2.

c) Punishments in the Code of Hammurabi were adjusted depending on the status of the perpetrator and the victim.
Step-by-step explanation:
The Code of Hammurabi reflected the social hierarchy of ancient Babylonia in that it differentiated punishments based on the social status of the perpetrator and the victim. For example, the code stipulated different punishments for crimes committed by a nobleman versus those committed by a commoner. This demonstrates that ancient Babylonian society was structured into a hierarchy, with different levels of privilege and responsibility assigned based on social status. The Code of Hammurabi, then, serves as a tangible expression of this social hierarchy, showing the ways in which the laws of the land reflected and reinforced existing power dynamics.

Find the area of parallelogram B

Answer:
6 units squared
Step-by-step explanation:
you take the squares that are split up and find another one that matches with it to make a full square
Answer:
2√10 or ~6.32 units squared
Step-by-step explanation:
Area = L x W
Since both the width and lengths are diagonals, they will both be the hypotenuse of triangles.
Width = √1^2+1^2
= √2
Length = √2^2+4^2
= 2√5
∴ Area = √2*2√5
= 2√10 or ~6.32 units squared
the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Answer:
mRJN = 75°
Step-by-step explanation:
VJA = 15°
If the line VJ would continue through J and stop at a point that we now call Z. Then the new angle ZJN which is a vertically opposite angle to VJA would also be 15°
Angle VJE is supplementary to VJR and therefore also 90°
And if angle VJE is 90°, that means its supplementary angle EJZ is also 90°.
Angle EJN (supplementary to RJN) is simply EJZ - ZJN = 90° - 15° = 75°
