The points in a coordinate plane are reflected in the y-axis. In general, every point (x, y) is mapped onto what point? (___,___)
In a Cartesian coordinate system, a point (x, y) reflected over the y-axis is mapped to the point (-x, y), as the x-component changes direction in the reflection while the y-component remains the same.
Explanation:When a point is reflected across the y-axis in a Cartesian xy-coordinate system, which has orthogonal directions defined by the unit vectors i and j for the x and y axis respectively, the coordinates of the point change in a specific way. For every point whose coordinates are initially (x, y), after being reflected over the y-axis, the resultant point will have coordinates (-x, y).
This happens because the reflection over the y-axis effectively reverses the direction of the x-component of the point's position vector, changing its sign from positive to negative or vice-versa, while leaving the y-component unaffected. Therefore, after reflection, a point (x, y) is mapped onto the point (-x, y).

An interior angle of a regular polygon has a measure of 108°. What type of polygon is it? The polygon is .
The polygon is a penthagon.
In a regular polygon with n sides, the sum of the interior angles is
[tex] 180(n-2) [/tex]
But we also know that each interior angle has a measure of 108, and of course there is a total of n angles. So, we also know that the sum of the interior angles is
[tex] 108n [/tex]
Since we have two expressions for the same quantity, these expressions must equal each other:
[tex] 180(n-2) = 108n [/tex]
To solve for n, let's start by expanding the left hand side:
[tex] 180n-360 = 108n [/tex]
Now move all terms involving n to the left hand side, and all constants to the right hand side:
[tex] 180n-108n = 360 [/tex]
Simplify the right hand side:
[tex] 72n = 360 [/tex]
And finally, divide both sides by 72:
[tex] n = \frac{360}{72} = 5 [/tex]
The correct polygon is, Pentagon
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
We have to given that;
An interior angle of a regular polygon has a measure of 108°.
Since, We know that;
In a regular polygon with n sides, the sum of the interior angles is
⇒ 180 (n - 2)
Here, The sum of the interior angles is,
⇒ 108n
Hence, We can formulate;
⇒ 108n = 180 (n - 2)
⇒ 108n = 180n - 360
⇒ 360 = 180n - 108n
⇒ 72n = 360
⇒ n = 5
Thus, It shows the Pentagon.

You thought the balance in ur cheking account was $68. When your bank statement arrives, you realize that you forgot to record a chem. The bank statement lists your balance as $26. Write and solve an equation to find out the amount of the chem that you forgot to record.
Final Answer:
The amount of the check that you forgot to record is $42.
Step-by-step explanation:
Let x represents the amount which is forgotten in recording.
Bank balance + Amount of money forgotten in recording = Balance while checking account
26 + x = 68
x = 68 - 26

Use the graph below to answer the question that follows:
graph of curve that passes through the following points, 0, 5; pi over 2, 2; pi, negative 1; 3 pi over 2, 2; 2 pi, 5.
What is the rate of change between the interval x = π and x = three pi over two?
The rate of change between x = π and x = three pi over two is 6/π.
Explanation:The rate of change between the interval x = π and x = three pi over two can be found by calculating the slope of the line connecting these two points on the graph. In this case, we can calculate the slope by finding the difference in y-values and dividing it by the difference in x-values:
Slope = (y₂ - y₁) / (x₂ - x₁) = (2 - (-1)) / (π - 3π/2) = (2 + 1) / (3π/2 - π) = 3 / (π/2) = 6 / π
Therefore, the rate of change between the interval x = π and x = three pi over two is 6/π.
The rate of change between x = π and x = three pi over two is 6/pi.
Explanation:The rate of change between the interval x = π and x = three pi over two can be found by determining the slope of the line connecting the two points on the graph corresponding to these x-values.
Using the coordinates (pi, -1) and (3 pi over 2, 2), we can calculate the slope as follows:
Slope = (change in y)/(change in x) = (2 - (-1))/(3 pi over 2 - pi) = 3/(pi/2) = 6/pi
So, the rate of change between x = π and x = three pi over two is 6/pi.

Find the circumference of a circle that has an area of 452.16 square meters. (Use 3.1416 as the value of π.)
Final answer:
The circumference of a circle with a given area is 75.40 meters
Explanation:
To find the circumference of a circle, we can use the formula C = 2πr, where C is the circumference and r is the radius. First, we need to find the radius from the given area.
The formula for the area of a circle is [tex]A = \pi r^2[/tex]
Rearranging the formula, we get [tex]r = \sqrt{(A/\pi \p).[/tex]
Now, substitute the given area (452.16 square meters) into the formula and solve for r:
[tex]r = \sqrt{(452.16/3.1416)[/tex]
= 12.00 meters
Finally, plug the value of r into the circumference formula:
[tex]C = 2\pi (12.00)[/tex]
= 75.40 meters

Eliza Savage received a statement from her bank showing a checking account balance of $324.18 as of January 18. Her own checkbook shows a balance of $487.38 as of January 29. The bank returned all of the cancelled checks but three. The amounts of these three checks are $15.00, $77.49, and $124.28. How much did Eliza deposit in her account between January 18 and January 29?
3 checks total : 15.00 + 77.49 + 124.28 = 216.77
that amount will still need to be deducted from the bank
so 324.18- 216.77=107.41
her checkbook has a total of 487.38
487.38-107.41 = 379.97 is the amount she deposited into her account
Answer:
The amount she deposited in her account between January 18 and January 29 is $379.97
Step-by-step explanation:
Given :
Eliza showing a checking account balance of $324.18 as of January 18.
Her own checkbook shows a balance of $487.38 as of January 29.
The bank returned all of the cancelled checks but three. The amounts of these three checks are $15.00, $77.49, and $124.28.
To Find : Eliza deposit in her account between January 18 and January 29.
Solution :
Eliza showing a checking account balance of $324.18 as of January 18.
Total amount of three checks = $15.00 + $77.49+ $124.28 =$216.77
The account balance after the deduction of three checks amount
= $324.18 -$216.77 = $107.41
So, the new balance is $107.41.
Her own checkbook shows a balance of $487.38 as of January 29.
So, the amount she deposited between January 18 and January 29
= $487.38-$107.41 = $379.97
Hence , The amount she deposited in her account between January 18 and January 29 is $379.97

Three painters can paint three walls in three minutes. how many painters are needed to paint 27 walls in nine minutes?
To paint 27 walls in 9 minutes, you would need 9 painters working at the same speed. This is based on the proportional relationship that each painter can paint 1 wall in 3 minutes.
Explanation:This problem can be solved with a clear understanding of proportions. Given that 3 painters can paint 3 walls in 3 minutes, it implies that each painter can paint 1 wall in 3 minutes.
Thus, in 9 minutes, a single painter can paint 3 walls.
Therefore, to paint 27 walls in 9 minutes, we would need 27/3 equals 9 painters.
It is important to note that this implies all painters are working at the same speed. This is a simple and practical example of proportions in mathematics
