What is the end behavior of the polynomial
Answer:
As x --> ∞, then y --> - ∞
Step-by-step explanation:
As the value of x increases(as the graph goes right), the graph seems to go down, meaning the y-values are getting more an more negative. This means that as x approached infinity, the y values approach negative infinity ( x --> ∞, y --> - ∞ ).
As the value of x decreases(going to the left), the graph seems to go higher and higher. Therefore, as x approaches negative infinity, the y-value approach infinity. ( x --> - ∞, y --> ∞ )
Out of the options given, the one As x --> ∞, then y --> - ∞ is true.
Draw in all lines of symmetry in the shape below. If there are no lines of symmetry, submit an answer without drawing them in.
It should be noted that the line of symmetry for the shape will be 5.
What is a line of symmetry?A line of symmetry is a line that divides a shape into two congruent parts that are mirror images of each other. In other words, if you fold the shape along the line of symmetry, the two halves will perfectly overlap.
Here are some examples of shapes and their lines of symmetry:
Square: A square has four lines of symmetry, which are the vertical, horizontal, and two diagonal lines.
Rectangle: A rectangle has two lines of symmetry, which are the vertical and horizontal lines.
Circle: A circle has an infinite number of lines of symmetry, because you can draw a line through the center in any direction.

To show that a statement is false, we need to find a counterexample where the statement does not hold true. Here are the counterexamples for each statement:
The sum of any three odd numbers is even.
Counterexample: 1 + 3 + 5 = 9, which is an odd number. Therefore, the statement is false.
When an even number is added to the product of two odd numbers, the result will be even.
Counterexample: 1 {square} 3 + 2 = 5, which is an odd number. Therefore, the statement is false.
When an odd number is squared and divided by 2, the result will be a whole number.
Counterexample: Let's take an odd number, say 3. If we square it, we get 3{square}2 = 9. If we divide 9 by 2, we get 4.5, which is not a whole number. Therefore, the statement is false.
In each of these cases, we have found a counterexample that shows that the statement is false. It is important to remember that just because a statement holds true for some examples, it does not necessarily mean it holds true for all examples.

For a project in her Geometry class, Aria uses a mirror on the ground to measure the height of her school building. She walks a distance of 11.45 meters from the school, then places a mirror on flat on the ground, marked with an X at the center. She then steps 1.25 meters to the other side of the mirror, until she can see the top of the school clearly marked in the X. Her partner measures the distance from her eyes to the ground to be 1.15 meters. How tall is the school? Round your answer to the nearest hundredth of a meter.
Answer = 10.53m
The height of the school building is approximately 9.69 meters or 10.53 meters (rounded to the nearest hundredth).
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the studies of relationships between angles and sides of triangles.
Let's denote the height of the school building as "h".
From the given information, we can draw a right triangle with the mirror on the ground, the top of the school building, and Aria's eyes as the vertices. The distance from Aria to the mirror is 1.25 meters, and the distance from the mirror to the school building is the unknown height "h". The distance from Aria's eyes to the mirror is 1.15 meters.
We can use similar triangles to set up an equation to solve for "h".
In the smaller triangle formed by Aria's eyes, the mirror, and the point directly below the top of the school building, we can see that:
h/1.25 = (h + 1.15)/11.45
This equation comes from the fact that the ratios of corresponding sides in similar triangles are equal.
Simplifying this equation gives us:
1.45h = 14.06875
Dividing both sides by 1.45 gives us:
h ≈ 9.6931
Hence, The height of the school building is approximately 9.69 meters or 10.53 meters (rounded to the nearest hundredth).

The functions below represent the cost some homeowners pay for water and sewer usage. This is based on the number of 100-gallon units
of water used, defined by x.
Water usage: W(x) = 0.129x
Sewer usage: S(x) = 0.158x + 16.22
Based on this information, approximately what is the total amount a homeowner will pay if the water and sewer usage for one month is 3800
gallons?
A. $10.91
B. $21.12
C. $27.13
D. $43.35
Since the given functions represent the cost for water and sewer separately, the total cost will be the sum of both.
For water usage, W(x) = 0.129x, where x is the number of 100-gallon units of water used. So, for 3800 gallons, we have:
W(x) = 0.129 * (3800/100) = $4.91 (rounded to the nearest cent)
For sewer usage, S(x) = 0.158x + 16.22, where x is the number of 100-gallon units of water used. So, for 3800 gallons, we have:
S(x) = 0.158 * (3800/100) + 16.22 = $21.12 (rounded to the nearest cent)
Therefore, the total amount a homeowner will pay for 3800 gallons of water and sewer usage for one month is:
Total cost = W(x) + S(x) = $4.91 + $21.12 = $26.03 (rounded to the nearest cent)
So, the closest answer choice is C. $27.13.

Unit rate = 0.6
y = 0.6x
x= 24
Step-by-step explanation:
I cannot see the headings to the table, but on examining the questions, the first column contains the values for variable x and the second column the values for variable y
Unit Rate
Unit rate = increase in y for a unit increase in x
We see that the rate is constant for every unit increase in x and is = 0.6
Unit rate = 0.6
Equation
The equation therefore is y = 0.6x
Value of x when y = 14.4
When y = 14.4, plugging into the equation gives:
14.4 = 0.6x
or
0.6x = 14.4 by switching sides - no effect on equation
Divide both sides by 0.6
0.6x/0.6 = 14.4/0.6
x= 24
what is 3 to the 2 power?
The equivalent to the expression 3², which equals 9.
An exponent is a mathematical operation that involves raising a number to a certain power. In this case, you are curious about what 3 to the 2 power means. Let's explore this concept further.
When we write 3 to the 2 power, it means that we are multiplying 3 by itself two times. This can also be written as 3 raised to the power of 2, which is represented by the notation 3².
To illustrate this concept, let's use an example. Consider the expression 3². This means that we need to multiply 3 by itself twice, as indicated by the exponent of 2. In other words:
3² = 3 x 3 = 9
So, 3 to the 2 power is equal to 9. Another way to think about this is to imagine a square with sides of length 3. The area of this square would be 3 x 3, or 9.
