Answer:
"(3)"
Step-by-step explanation:
Relation is a mapping between x-values and y-values. Xs are the domain and Ys are the range.
Given x values (0,3,6) and y-values(8, 2, -1), this is a relationship, so it is a relation.
To check whether a relation is a function or not, we simply see if each unique x value is paired with a unique y value.
Is there any y value that is same for x-values? NO! All are different. So this is a function as well!
Answer choice (3) is right.
Answer: (3) both a relation and a function
Step-by-step explanation:
Relation : It is the relation established between two set of values
Function : It is a kind of relation, where only output exist for e ach input.
Generally x values presents input values and y values represents the output values.
The given table :
x - y
0 - 8
3 - 2
6 - 1
Here, each x value is related to a y-value , so its a relation.
Also, there only one unique y-value for each x-values, thus its a function.
Hence, the set of ordered pairs in the mapping below can be described as both a relation and a function.
When developing a plan for a proof, it is important to look at the "given" information. True False
Answer:
Yeah true
Step-by-step explanation:
Because it makes sense
It is true that when developing a proof, focusing on the "given" information is crucial as it forms the foundation of the logical argument leading to the conclusion that needs to be proven.
When developing a plan for a proof, it is indeed important to look at the "given" information. This is true because in the context of mathematical proofs, the "given" information represents the starting point from which you will build you argument to reach a conclusion. These are the facts, definitions, or previously proven theorems that can be used in establishing the validity of the statement you are tasked to prove.
To develop a successful proof, one generally follows a systematic approach:
Identify the given information in the problem.Analyze what the problem is asking you to find or prove.Consider what principles, theorems, or rules apply based on the given information.Develop a logical sequence of steps that connects the given information to the conclusion you are trying to reach.This structured approach to problem-solving involves using what you know to logically arrive at a conclusion that was previously unknown or needs to be proven. This method not only applies to mathematics but also to other fields that require logical reasoning and evidence-based conclusions.

The vertex of this parabola is at (-1,-3). Which of the following could be it’s equation?
Answer:D
Step-by-step explanation: The vertex is (-1, -3), and since it's in terms of y, the y-coordinate is in the parentheses. D is the only choice with -3 as the y-coordinate.
The equation of the parabola with vertex (-1, -3) is y = a(x + 1)^2 - 3.
Explanation:The equation of a parabola in vertex form is y = a(x - h)^2 + k, where the vertex is (h, k). In this case, the vertex is (-1, -3), so the equation could be y = a(x + 1)^2 - 3. The coefficient a determines the shape of the parabola.The vertex of a parabola is the point where the parabola crosses its axis of symmetry. If the coefficient of the x2 term is positive, the vertex will be the lowest point on the graph, the point at the bottom of the “ U ”-shape. If the coefficient of the x2 term is negative, the vertex will be the highest point on the graph, the point at the top of the “ U ”-shape.

What is the standard form equation of the line shown below?
find the area of each figure. round to the nearest tenth if necessary .
We first would divide the Pentagon into two shapes, one a square and the other a triangle. To find the height of the triangle we must minus the 15cm to the 10cm, which gives us 5cm.
5cm= height of triangle
7cm= base of triangle
Then, apply the area of triangle formula
which is: A=(b×h)÷2
so the area would be 17.5cm squared.
For the square, 10= height and the 7=base
The formula for rectangles is:
A=b×h
so, the area is 70cm squared.
if you want the total area add the two area together, which equals 87.5cm squared.
I hope this helps.
To find the area of each figure, we can use different formulas depending on the shape. If the figure is a square or rectangle, we can use the formula A = length x width. If the figure is a circle, we can use the formula A = πr², where r is the radius.
Explanation:To find the area of each figure, we can use different formulas depending on the shape. If the figure is a square or rectangle, we can use the formula A = length × width. If the figure is a circle, we can use the formula A = πr², where r is the radius. For triangles, we can use the formula A = ½base × height. For irregular shapes, we can approximate the area by breaking it down into simpler shapes and summing up their areas.
Let's say we have a square with side length 5 cm. Using the formula A = length × width, the area would be A = 5 cm × 5 cm = 25 cm². If we have a circle with a radius of 2 cm, using the formula A = πr², the area would be A = 3.14 × 2 cm × 2 cm = 12.56 cm² (rounded to the nearest tenth).

The volume of a rectangular prism is (x3 – 3x2 + 5x – 3), and the area of its base is (x2 – 2). If the volume of a rectangular prism is the product of its base area and height, what is the height of the prism?
Answer:
height = (x^3 – 3x^2 + 5x – 3) / (x^2 – 2)
Step-by-step explanation:
We know that the volume of a rectangular prism is the product of its base area and height
Volume_prism = area_base * height
height = Volume_prism / area_base
Volume_prism = (x^3 – 3x^2 + 5x – 3)
area_base = (x^2 – 2)
height = Volume_prism / area_base
height = (x^3 – 3x^2 + 5x – 3) / (x^2 – 2)

Answer:
B) translation 2 units to the right
B) reflection across the y-axis
Step-by-step explanation:
If you move ABCD over to the right by 2, then reflect it over the y axis. Then you get the A'BCD.
ABC goes through a sequence of transformations to form A'B'C'. The sequence of transformations involved are
B) translation 2 units to the right and followed by a
B) reflection across the y-axis
This can be explained by using the graph and the definition of transformation
Transformations:Transformations are changes done in the shapes on a coordinate plane There are four types of transformations. They are translation, rotation, reflection, and dilationThe translation is moving a function in a specific direction, rotation is spinning the function about a point, reflection is the mirror image of the function, and dilation is the scaling of a functionThe translation, rotation, and reflection are called rigid transformations wherein the image is congruent to its pre-image. These are isometric transformationsDilation stretches or shrinks the pre-image i.e., expands or contracts the shape. It is non-isometric.The sequence of transformations involved:From all the information given above, it came to know that the sequence of transformations involved in transforming ABC to A'B'C' is translation and reflection.ABC is translated by 2 units to the right, it is shown in the graphAnd followed by a reflection across the y-axisThere is no rotation happenedThus, from the graph it is clear that the sequence of transformations involved is B) translation by 2 units to the right and followed by a B) reflection across the y-axis.

Which function is shown on the graph?
ANSWER
The correct choice is C.
EXPLANATION
The given graph has vertical asymptote at x=1.
Therefore , the denominator of the function represented by the graph should be 1-x
The graph also has a horizontal asymptote at y=-6. The numerator should be of the form
b+6x,
where b is a constant.
So that the horizontal asymptote will be
[tex]y = \frac{6}{ - 1} = - 6[/tex]
Our rational function now becomes
[tex]y = \frac{b + 6x}{1 - x} [/tex]
The function also has a y-intercept of 3,
[tex]3 = \frac{b + 6(0)}{1 - 0} = b[/tex]
Therefore the required function is

which of the following is the solution to |10x|>-2
Let's reason through it.
We are given the inequality that says, in English, that the absolute value of ten times x is greater than -2.
Let's consider three cases:
x is negative
- When x is negative the number in the absolute value will be negative. But because it is inside the absolute value, the number becomes positive. Therefore, for any x that is negative (however small or large), the left side will be positive. Any positive value (however small) is greater than a negative value, so the inequality is satisfied in this case.
x is positive
- When x is positive, the number inside the absolute value will be positive. The absolute value of a positive number is itself, so the left hand side will be positive again. Then, for all positive values of x (however small or large), the inequality will be satisfied because any positive value is larger than -2.
x is zero
- Even in the case of zero, when the left hand side will be zero, the equality is satisfied. This is because zero is greater than -2. If this doesn't immediately make sense, imagine the two numbers on the number line. 0 is to the right of -2, so it is larger.
Since we cannot find a value for x that does not satisfy the inequality, the solution to the inequality is all values of x. See the attached image.

the length and width of a rectangle are consecutive even integers. the area of the rectangle is 120 square units. what are the length and width of the rectangle
The length and width of the rectangle is 12 and 10 respectively.
Let the consecutive integers be :
a ; a+2Area of rectangle = Length × width
120 = a(a + 2)
120 = a² + 2a
a² + 2a - 120 = 0
a² - 10a + 12a + 120 = 0
a(a - 10) + 12(a - 10)
a = 10 or a = -12
The width cannot be negative, Hence, width = 10
Length = a + 2
Length = 10 + 2
Length = 12
The length and width of the rectangle is 12 and 10 respectively.
