Answers
Answer:
B
Step-by-step explanation:
that is the definition of a function : every valid value of x gets exactly one value of y assigned as function result value.
that allows gaps. not every value on the x-axis has to be a valid x value for the function. and neither do we need every possible y value to be a valid function result value.
so, if we consider x to be the set of {2, 4, 6, 9}, then this is indeed a function.
2 gets 3, 4 gets 9, 6 gets 10, and 9 gets 5 assigned as y (function result) value.
all good and perfect - exactly one assigned value for every valid x value.

A square has a perimeter of 16 units and an area of 16 square units. What is the side length of the square? Show your work.
Answers
Answer:
4 units
Step-by-step explanation:
according to question:
perimeter of square = 16 units
4a = 16
where a is the side length
a = 16/4
= 4 units
Step-by-step explanation:
that r = P/(2π) so A = π(P/(2π))2 = P2/(4π). Any positive area less than this is also possible. So in this problem the largest area possible is (16 in.)2/(4π) = 64/π sq.
The picture above represents a small section from the periodic table. Which of the elements has chemical properties most similar to element X?

Answers
The element that has chemical properties most similar to element X is element 1.
What are the relations in the periodic table?Elements on the periodic table are ordered accordingly to the number of protons in each element.
The first one is hydrogen, with 1 proton, the second is helium, with two protons, and so on.
So, element 3 has one proton less than x, and element 4 has one proton more than x.
Then we have two more relations:
Horizontal lines are called periods, so 3, x, and 4 are on the same period (it is related to the energy level of the valence's electrons).
Vertical lines are called families because elements in vertical lines have similar chemical behavior.
This is the one that we care for this problem, we want to see which element has chemical properties most similar to element X, so we need to see which element is on the same family as element X.
As you can see, the only element on the same vertical line as X is element 1, so the correct option will be A.

The first part of Ray and Kelsey's roller coaster is a curved pattern that can be represented by a polynomial function.
Ray and Kelsey are working to graph a third-degree polynomial function that represents the first pattern in the coaster plan. Ray says the third-degree polynomial has 4 intercepts. Kelsey argues the function can have as many as 3 zeros only. Is there a way for the both of them to be correct? Explain your answer.
Kelsey has a list of possible functions. Pick one of the g(x) functions below and then describe to Kelsey the key features of g(x), including the end behavior, y-intercept, and zeros.
g(x) = x3 − x2 − 4x + 4
g(x) = x3 + 2x2 − 9x − 18
g(x) = x3 − 3x2 − 4x + 12
g(x) = x3 + 2x2 − 25x − 50
g(x) = 2x3 + 14x2 − 2x − 14
Create a graph of the polynomial function you selected from Question 2.
Part B
The second part of the new coaster is a parabola.
Ray needs help creating the second part of the coaster. Create a unique parabola in the pattern f(x) = ax2 + bx + c. Describe the direction of the parabola and determine the y-intercept and zeros.
The safety inspector notes that Ray also needs to plan for a vertical ladder through the center of the coaster's parabolic shape for access to the coaster to perform safety repairs. Find the vertex and the equation for the axis of symmetry of the parabola, showing your work, so Ray can include it in his coaster plan.
Create a graph of the polynomial function you created in Question 4.
Part C
Now that the curve pieces are determined, use those pieces as sections of a complete coaster. By hand or by using a drawing program, sketch a design of Ray and Kelsey's coaster that includes the shape of the g(x) and f(x) functions that you chose in the Parts A and B. You do not have to include the coordinate plane. You may arrange the functions in any order you choose, but label each section of the graph with the corresponding function for your instructor to view.
Part D
Create an ad campaign to promote Ray and Kelsey's roller coaster. It can be a 15-second advertisement for television or radio, an interview for a magazine or news report, or a song, poem, or slideshow presentation for a company. These are just examples; you are not limited to how you prepare your advertisement, so be creative. Make sure to include a script of what each of you will say if you are preparing an interview or a report. The purpose of this ad is to get everyone excited about the roller coaster.

A toy maker used 36 batteries for his 9 new toy cars. The toy maker uses the same amount of batteries for each toy car. Which table shows the relationship between the amount of batteries and the amount of toy cars? = 25x
Answers
The table that shows the proportional relationship between the number of batteries and the number of toy cars is as follows:
x = 12, y = 3x = 24, y = 6x = 48, y = 12 Proportional relationshipproportional relationships are relationships between two variables where their ratios are equivalent.
Therefore, If we establish the relationship between the number of batteries and the number of car toys, we can draw the table.
Therefore,
let
y = kx
where
y = number of toys
x = number of batteries
Therefore,
9 = 36k
k = 9 / 36
k = 1 / 4
y = 1 / 4 x
Therefore,
x = 12, y = 12 / 4 = 3x = 24, y = 24 / 4 = 6x = 48, y = 48 / 4 = 12The question wants to draw a table for the proportional relationship between x(number of batteries) and y(number of toy cars).
