Resizing or changing an object is the process of dilation. Through the use of the specified scale factor, it is a transformation that reduces or enlarges the objects.
What is Dilation Geometry?The pre-image refers to the original figure and the new figure that results from dilation is known as the image. Two forms of dilation exist:An object's size expands when it undergoes expansion.When an object gets smaller, the process is called contraction.The following illustration, which depicts a square dilating, should be noted. However, the square's shape doesn't change; rather, its size is raised.In mathematics, dilation is the process of modifying an object's or shape's size without altering its shape. The form could be a point, a section of a line, a polygon, etc. It should be noted that while the shape can be altered in size, the proportions of its various dimensions and angles never change.The angles are the same when PQR is increased to P'Q'R. After dilatation, the vertices of the PQR have new coordinates.P(1,3) → P' (3,9) (3,9)
Q(3,1) → Q' (9,3) (9,3)
R(1,1) → R' (3,3) (3,3).

According to the given we can state:
AD = BC = AB = 2AO = 2,EO is the perpendicular bisector of AB,Arc AC and arc BD are of equal length.Find arc AB, it is a semicircle of 1 cm radius:
arc(AB) = 1/2 × 2πr = πr = π cmΔAEO and ΔBEO are both isosceles, hence ∠A and ∠B are both 45°.
Find arcs ABD and BAC:
arc(ABD) + arc(BAC) = 2 × 45/360 × 2πr = 1/2 × πr = π cm∠AEB is a right angle since ∠AEO and ∠BEO are both 45°.
Hence ∠CED is also right angle as vertical angle with ∠AEB.
Find the length of EC and ED.
We know AD = BC = 2 cm and ΔAEO is 45° right triangle.
It gives us:
AE = √2Then:
ED = AD - AE = 2 - √2Find arc ECD:
arc(ECD) = 1/4 × 2πr = 1/2 × π(2 - √2) = π - π√2/2 cmThe perimeter is the sum of all the arc measures:
P = π + π + π - π√2/2 = 3π - π√2/2 or 7.2 cm (rounded)Answer:
[tex]\textsf{Perimeter}=3\pi-\dfrac{\pi}{\sqrt{2}}=7.20333649...\; \sf cm[/tex]
Step-by-step explanation:
[tex]\boxed{\begin{minipage}{6.4 cm}\underline{Arc length}\\\\Arc length $=r \theta$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $\theta$ is the angle measured in radians.\\\end{minipage}}[/tex]
To convert degrees to radians, multiply the angle in degrees by π/180°.
Arc AB
As arc AB has center O, the radius of arc AB is OA = 1 cm.
As AB is a straight line, ∠AOB is 180° = π.
Therefore, the length of arc AB is:
[tex]\implies AB=r \:\theta=1 \cdot \pi = \pi[/tex]
Arc AC
Triangle BOE is a right triangle with base of 1 cm and height of 1 cm.
Therefore, ∠OBE is 45° = π/4
If arc AC has center B, then the radius is AB = 2 cm.
Therefore, the length of arc AC is:
[tex]\implies AC=r \:\theta=2 \cdot \dfrac{\pi}{4} = \dfrac{\pi}{2}[/tex]
Arc BD
Arc BD is the same as arc AC.
[tex]\implies BC= \dfrac{\pi}{2}[/tex]
Arc CD
As triangle BOE is a right triangle with base of 1 cm and height of 1 cm, the length of its hypotenuse BE is:
[tex]\implies BE=\sqrt{1^2+1^2}=\sqrt{2}[/tex]
As arc AC has center B and radius of AB = 2 cm, then BC is also its radius and therefore BC = 2 cm
Therefore:
[tex]\implies CE=BC-BE[/tex]
[tex]\implies CE=2-\sqrt{2}[/tex]
The arc CD has center E so its radius is CE = 2-√2.
As ∠BEO and ∠AEO are both 45° then ∠AEB is 90°.
According to the vertical angle theorem, ∠CED is also 90° = π/2.
Therefore, the length of arc CD is:
[tex]\implies CD=r \:\theta=(2-\sqrt{2}) \cdot \dfrac{\pi}{2} = \dfrac{(2-\sqrt{2})\pi}{2}[/tex]

• You deposit your paycheck on October 23 ($7.25/hour for 40 hours/wk for 2 weeks with deductions of FICA (7.65%), federal withholding (12%), and state withholding (8.75%).
• You buy $78.54 plus 6% sales tax in clothes from FitRight on October 24 using your debit card.
Be sure to include in your response:
• the steps you followed to complete your computations.
• the balance as of October 24
•the process for entering the transaction in the registry
Answers
Answer:
To complete the transactions in your register:
Beginning balance on October 1: $542.89
On October 7, you pay Land Electric $43.90. This is a check transaction and the check number is 400. To record this in your register, you would subtract $43.90 from your current balance, which would bring your new balance to $498.99.
On October 23, you deposit your paycheck. To calculate your paycheck, you would multiply your hourly wage ($7.25) by the number of hours worked (40) by the number of weeks (2). This would give you a gross pay of $1140. Then, you would calculate the deductions: FICA (7.65%), federal withholding (12%), and state withholding (8.75%). To do this, you would multiply your gross pay by the percentage for each deduction and then subtract that amount from the gross pay. Your final paycheck would be $1140 - $87.41 (FICA) - $136.8 (federal withholding) - $100.65 (state withholding) = $815.34. To record this in your register, you would add $815.34 to your current balance, which would bring your new balance to $1314.33
On October 24, you buy $78.54 in clothes from FitRight and pay 6% sales tax. To calculate the sales tax, you would multiply $78.54 by 0.06 and add that amount to the total cost of the clothes. The total cost of the purchase including sales tax would be $78.54 + $4.71 = $83.25. To record this in your register, you would subtract $83.25 from your current balance, which would bring your new balance to $1231.08
The balance as of October 24 would be $1231.08
In the register
10/1 Beginning balance $542.89
10/7 Check #400 Land Electric -$43.90

Solve x2 – 8x + 15 < 0. Select the critical points for the inequality shown. –15 –5 –3 3 5
Answers
Answer: To solve the inequality x^2 - 8x + 15 < 0, we first want to find the critical points, which are the points where the quadratic function changes direction (from increasing to decreasing or vice versa). To find the critical points, we need to set the quadratic equal to zero and solve for x. In this case, we have:
x^2 - 8x + 15 = 0
To solve this equation we should factor it or use the quadratic formula.
(x - 5)(x - 3) = 0
x = 5, x = 3
This means that the critical points for the inequality are x = 5 and x = 3. To find the solution set of the inequality, we test the signs of the function at the critical points and in the intervals between them.
The solution of the inequality is x < 3 or x > 5.

how do find the factors of a fraction Example 3 1/2 (unit rate, proportionality)
Answers
The factors of a fraction 3 1/2 is 3/2.
What are the factors?Generally, A divisor of an integer n, also known as a factor of n, is an integer m that can be multiplied by another number to generate n. Another name for this concept is a factor of n. One may also state that n is a multiple of m in this particular scenario.
Since 3/2 is a fraction, it does not have any factors since factors are integers that may evenly divide a number. Since 3/2 is a fraction, it does not have any factors. Only integers are capable of having factors; fractions are unable to do so.
To find the factors of a fraction, you can factor the numerator and denominator separately.
In the case of 3 1/2, the numerator 3 is a prime number and cannot be factored further.
However, the denominator 2 can be factored as 2 x 1.
Therefore, the factors of 3 1/2 are: (3 x 1) / (2 x 1),
which can be simplified to 3/2.

Suppose Kristen is researching failures in the restaurants business
Answers
The standard deviation of the number of restaurants that failed within a year is 3.46.
What is Normal Distribution?The normal distribution, also known as the Gaussian distribution, is a symmetric probability distribution about the mean, indicating that data near the mean occur more frequently than data distant from the mean. The normal distribution will show as a bell curve on a graph.
Given that the probability that an independent restaurant will fail in the first year is 48%. Therefore, the probability can be written as,
p = 48% = 0.48
q = 1-p = 1-0.48 = 0.52
Also, Kristen obtains a random sample of 66 independent restaurants that opened in her city more than one year ago and determines if each one had closed within a year. Therefore, the sample size is 53.
n = 53
Now, the standard deviation can be calculated as,
Standard deviation, σ = √(npq)
= √(53 × 0.48 × 0.52)
= √11.9808
= 3.46

Nicole cycled 9 laps on a bicycle path around the lake. If each lap was 9540ft long, what was the total distance she cycled? Write your answers in miles.
Answers
Answer:
162 miles.
Step-by-step explanation:
To find the total distance Nicole cycled, we can multiply the number of laps by the length of each lap.
The total distance Nicole cycled is:
9 laps * 9540 ft/lap = 858,600 ft
To convert this distance to miles, we can use the conversion factor that there are 5280 feet in a mile.
858,600 ft / 5280 ft/mile = 162 miles
So the total distance Nicole cycled is 162 miles.

Answers
The area of triangle MNB, MNC and ABC 6 in.², 60 in.², and 30 in.² respectively
How to find the area of the triangle?The ratio of the base of the triangles ΔMNB and ΔCBM, that shares a common vertex, is the ratio of their areas.
M is the midpoint of side AB in ΔABC
NB:CB = 1:5
Area of ΔCAM = 30 in.²
The area of ΔMNB and ΔABC
Area = 1/2 * base * height
Height of ΔCAM = Height of ΔCBM = Altitude of point C above line AB
MA = MB by definition of midpoint
MA is the base of ΔCAM, and MB is the base of ΔCBM
Therefore; Area of ΔCAM = 1/2 AM * Height of ΔCAM
= 1/2 * AM* height of ΔCAM
Which gives;
Area of ΔCAM = Area of ΔCBM = 30 in.²
Area of ΔABC = Area of ΔCAM + Area of ΔCBM = 30 + 30 = 60
Area of ΔABC = 60 in.²
Taking CB as the base of ΔCBM, we have;
Height of ΔMNB = Height of ΔCBM from line CB
Base length of ΔCBM = 5 × Base length of ΔMNB
Therefore; Area of ΔMNB = 30/5 = 6 in²
Area of ΔCBM = 30 in.² = 5 × The area of ΔMNB
Conclusively, the Area of ΔMNB = 6 in.²

What is mathematical equation?An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated by the symbol "equal." The link between two expressions on either side of the sign is represented by a mathematical equation. One variable and an equal sign are typically present. For instance, 2x – 4 = 2. The smallest equivalent fraction of the number is considered to be its simplest form. What to do to discover the simplest form? Investigate the numerator and denominator for shared factors. To see if a fractional number is a prime number, check it.Our first line in this equation is y=2x-1. By applying the equation y=mx+b, where "m" stands for the slope, we can see that our "m" in this instance is 2. then negate 2. It turns into -2.
Change the denominator and numerator after that. Since -2 is actually -2/1, let's change it to -1/2. The perpendicular line's slope is that.
We must now make it pass through (-2,6). We just have a line like this to work with at the moment: y=-1/2x
Plugging in the x-coordinate of our target location, -2, yields y=-1/2(-2), or 1. But hold on, because the y-coordinate we were given is 6, shouldn't y be equal to 6 as well? Yes! The only thing left to do is to add 5 to get from 1 to 6!

The sides of MNPQ are represented by the expressions below. Find the perimeter of MNPQ.
MW=-2+37
QP= y+14
NP= x-5
MN=4y+5
perimeter: ? units
Answers
Answer:
Step-by-step explanation:
The perimeter of a polygon is the sum of the lengths of all its sides. To find the perimeter of MNPQ, we need to add up the lengths of MN, NP, PQ and PM.
Given that:
MW=-2+37 = 35
QP= y+14
NP= x-5
MN=4y+5
The perimeter can be calculated by adding up the above expressions:
Perimeter = MN + NP + QP + MW
= (4y + 5) + (x - 5) + (y + 14) + 35
= 4y + x + y + 54
= (4y + y) + (x + 54)
= 5y + x + 54
So the perimeter of MNPQ is 5y + x + 54 units.

A newspaper article headline reads "One in Five Believe the Path to Riches is the Lottery". A survey was done to test the claim that 20% of adult Americans believe that the lottery is the path to riches. The hypothesis test of H0: p=.2 versus Ha: p>.2 resulted in 0.79 for a right-tailed test. Calculate the p-value and write the correct conclusion in context.
Answers
The p-value for right tailed test based on the information will be 0.2147.
What is the p-value?The p-value, under the assumption that the null hypothesis is true, is the likelihood of obtaining results from a statistical hypothesis test that are at least as extreme as the observed results. The p-value provides the smallest level of significance at which the null hypothesis would be rejected as an alternative to rejection points. The alternative hypothesis is more likely to be supported by stronger evidence when the p-value is lower.
In this case, the survey was done to test the claim that 20% of adult Americans believe that the lottery is the path to riches. The hypothesis test of H0: p=.2 versus Ha: p>.2 resulted in 0.79 for a right-tailed test
The Z statistic given to be =0.79 for a right tailed test. Here, by looking aththe distribution table, the p value for Z=0.79 for one tail test is 0.2147.
So, we do not reject null hypothesis and then conclude that data does not provide sufficient evidence that the proportion of Americans who believe path to riches is the lottery is greater than 0.2

Sea level is defined as having an elevation of 0. A dolphin is 7 meters below sea level.
How should the value 2(-7) be interpreted in this context?
A. a location that is twice as far below sea level as the dolphin
B. a location that is twice as far above sea level as the dolphin
C. a location that is 2 meters closer to sea level than the dolphin
D. a location that is 2 meters farther from sea level than the dolphin
Help…
Answers
The value 2(-7) is interpreted that a location that is twice as far below sea level as the dolphin. Option A is the correct option.
What is the meaning of interpretation?
Elucidate, explain, explicate, and expound are some synonyms for interpret. While all of these words mean "to make something clear or understandable," interpretation adds to explain why dealing with something requires imagination, sympathy, or special knowledge.
Given that sea level is defined as having an elevation of 0. A dolphin is 7 meters below sea level.
If the level is below sea level, then it can represent by a negative number.
The statement "A dolphin is 7 meters below sea level." can be written as:
A dolphin is -7 meters far from sea level.
Thus 2(-7) represents a location that is 7 meters below the dolphin's position.

Solve for n. 7n - 2 = 5n + 6
Answers
Answer:
n = 4
Step-by-step explanation:
Pre-SolvingWe are given the equation 7n - 2 = 5n + 6, ans we want to solve it for n.
To do this, we need to isolate n one one side.
SolvingLet's start by adding 2 to both sides.
7n - 2 = 5n + 6
+2 +2
_______________
7n = 5n + 8
Now, subtract 5n from both sides.
7n = 5n + 8
-5n -5n
_______________
2n = 8
Divide both sides by 8 to get the value of n.
2n = 8
÷2 ÷2
________
n = 4
