2. Kyle submits a design for the contest, but his
explanation was misplaced. How can Figure A be
mapped onto Figure B? Can any other transformation be
used to map Figure A onto Figure B?
Note that in order to map A onto B, Kyle would have to dilate the given figure by a scale factor or 3.
What is a scale factor?The scale factor is a metric for figures with similar appearances but differing scales or measurements. Assume two circles appear similar but have different radii. The scale factor specifies how much larger or smaller a figure is than the original figure.
The original point of figure A which has 4 points are

Engineers built an arch bridge across a river. The arch bridge
makes a parabola shape that has the equation
y=-0. 1(x – 5)2 + 12, where x and y are measured in
meters. If the bridge makes contact with both banks at a height
of 4 meters, how long is the distance between the two banks
of the river where the bridge is? Round your answer to the
nearest whole number.
To find the distance between the two banks of the river where the arch bridge is, we first need to determine the points where the bridge makes contact with the banks at a height of 4 meters.
We are given the parabola shape of the arch with the equation y = -0.1(x - 5)^2 + 12.
1. Set the height y equal to 4 meters:
4 = -0.1(x - 5)^2 + 12
2. Subtract 12 from both sides:
-8 = -0.1(x - 5)^2
3. Divide both sides by -0.1:
80 = (x - 5)^2
4. Take the square root of both sides:
sqrt(80) = x - 5
5. Now, we find the two x-values where the bridge contacts the banks:
x1 = sqrt(80) + 5
x2 = -sqrt(80) + 5
6. Calculate the distance between the two banks by subtracting x2 from x1:
Distance = x1 - x2 = (sqrt(80) + 5) - (-sqrt(80) + 5)
7. Simplify the expression:
Distance = 2 * sqrt(80)
8. Round your answer to the nearest whole number:
Distance ≈ 18 meters
The distance between the two banks of the river where the arch bridge is, is approximately 18 meters.

The function that can be used to find the amount in dollars a passenger has to pay to fly with `p` pieces of luggage, where `p > 2` is: `C(p) = 439 + 25(p-2)`
- The base cost of the flight is $439.
- Customers may check 2 pieces of luggage without any additional fee.
- For each additional piece of luggage beyond 2, there is a fee of $25.
- If `p` is the number of pieces of luggage checked, then the number of additional pieces of luggage beyond 2 is `p - 2`.
- Therefore, the additional fee for `p` pieces of luggage beyond the first 2 is `25(p - 2)`.
- Adding this fee to the base cost gives the total cost `C(p)`:
C(p) = base cost + additional fee for (p-2) pieces of luggage

How many degrees are in the acute angle formed by the hands of a clock at 3:30?
The acute angle formed by the hands of a clock at 3:30 is 75 degrees. An acute angle is an angle that measures less than 90 degrees, and in this case, the hour hand is pointing at the 3, which is a 90-degree angle from the 12, while the minute hand is pointing at the 6, which is a 180-degree angle from the 12.
Find the number of degrees in the acute angle formed by the hands of a clock at 3:30, follow these steps:
Determine the position of the hour hand. At 3:30, the hour hand is halfway between 3 and 4, so it's at 3.5 hours. Convert this to degrees by multiplying by 30 (since there are 360 degrees in a circle and 12 hours on a clock, each hour represents 30 degrees).
So, the hour hand is at 3.5 x 30 = 105 degrees.
Determine the position of the minute hand. At 3:30, the minute hand is on 6, which is 180 degrees around the clock.
Find the difference between the two positions.
Subtract the smaller angle from the larger angle: 180 - 105 = 75 degrees.

Brooke bought a condominium for $413,600. She made a 9% down payment and financed the remaining amount using a 25-year fixed-rate mortgage at 5. 2%. The monthly payment is $2,244. Brooke will pay for one discount point, a 0. 75% origination fee, the brokerage fee, state documentary taxes on the deed and the mortgage, and the intangible tax. • Discount points equal 1% of the mortgage amount. Documentary stamp tax on deed is $0. 70 per $100 or portion thereof. • Documentary stamp tax on mortgage is $0. 35 per $100 or portion thereof. • Mortgage broker fee is $175 plus 5% of the mortgage amount. • Intangible tax is 0. 2% of the mortgage amount. What is the total amount of the principal, interest, down payment, and fees described for Brooke's condominium? (4 points) $743,687. 00 $807,569. 73 $481,369. 73 $740,969. 73
The total amount of the principal, interest, down payment, and fees described for Brooke's condominium is $1,154,091.59
Find out the total amount of the principal and interest down payment, and fees?The first step is to calculate the mortgage amount, which is the purchase price minus the down payment:
Mortgage amount = $413,600 - 9% of $413,600 = $376,576
Next, we need to calculate the total cost of the fees and charges:
Discount points = 1% of $376,576 = $3,766
Origination fee = 0.75% of $376,576 = $2,823.42
Documentary stamp tax on deed = $0.70 per $100 or portion thereof, so for $413,600 it would be:
$0.70 * ($413,600 / $100) = $2,895.20
Documentary stamp tax on mortgage = $0.35 per $100 or portion thereof, so for $376,576 it would be:
$0.35 * ($376,576 / $100) = $1,318.02
Brokerage fee = $175 + 5% of $376,576 = $19411.8
Intangible tax = 0.2% of $376,576 = $753.15
Now we can calculate the total cost of the principal and interest payments over the life of the mortgage. We'll use a mortgage calculator to do this, based on the mortgage amount, interest rate, and term:
Total mortgage payments = $2,244 * 12 months * 25 years = $673,200
Finally, we can add up all of these amounts to get the total cost of the principal, interest, down payment, and fees:
Total cost = Purchase price + Down payment + Mortgage payments + Discount points + Origination fee + Documentary stamp tax on deed + Documentary stamp tax on mortgage + Brokerage fee + Intangible tax
Total cost = $413,600 + $37,224 + $673,200 + $3,766 + $2,823.42 + $2,895.20 + $1,318.02 + $19,411.80 + $753.15
Total cost = $1,154,091.59
Therefore, we got a total cost of $1,154,091.59

A. The missing value for P(X = 1) is 0.20.
B. The value of P(X ≤ 2) is 0.85.
C. The value of P(X > 2) is 0.15.
D. The probability of "At least 2" is equivalent to P(X >= 2), which is 0.75.
In probability theory, a probability distribution is a function that assigns probabilities to each possible value of a random variable.
In this Problem, we have a probability distribution for the score on a quiz, with X being the random variable and the table providing the probability of each possible score. In this answer, we will use the given probability distribution to answer the questions posed.
A) Find the missing value for P(X = 1) in the probability distribution.
To find the missing value for P(X = 1), we need to use the fact that the sum of the probabilities for all possible values of X must be equal to 1. Therefore, we can set up an equation:
P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 1
Substituting in the given probabilities, we get:
0.05 + P(X = 1) + 0.60 + 0.15 = 1
Simplifying, we get:
P(X = 1) = 0.20
Therefore, the missing value for P(X = 1) is 0.20.
B) P(X ≤ 2) =
To find P(X ≤ 2), we need to add up the probabilities of X being less than or equal to 2. This is equivalent to:
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
Substituting in the given probabilities, we get:
P(X ≤ 2) = 0.05 + 0.20 + 0.60 = 0.85
Therefore, P(X ≤ 2) is 0.85.
C) P(X > 2) =
To find P(X > 2), we need to add up the probabilities of X being greater than 2. This is equivalent to:
P(X > 2) = P(X = 3)
Substituting in the given probabilities, we get:
P(X > 2) = 0.15
Therefore, P(X > 2) is 0.15.
D) The probability of "At least 2" is equivalent to P(X >= 2)
To find the probability of "At least 2," we need to add up the probabilities of X being greater than or equal to 2. This is equivalent to:
P(X ≥ 2) = P(X = 2) + P(X = 3)
Substituting in the given probabilities, we get:
P(X ≥ 2) = 0.60 + 0.15 = 0.75
Therefore, the probability of "At least 2" is equivalent to P(X ≥ 2), which is 0.75.

Find the coordinates of a point P on the line and a vector v parallel to the line. X-7 - Y + 2 = 2 + 6 = 5 4 P(x, y, z) = V ="
To find the coordinates of point P on the line, we can solve for x and y in the equation X-7 - Y + 2 = 2 + 6 = 5. Adding 7 to both sides, we get X - Y + 2 = 12. Subtracting 2 from both sides, we get X - Y = 10. We can choose any value for x, and then solve for y using this equation. For example, if we choose x = 0, then y = -10.
So the coordinates of point P on the line could be (0, -10, z), where z is any real number.
To find a vector v parallel to the line, we can take two points on the line and find the vector between them. For example, we could use the points (0, -10, 0) and (1, -9, 0). The vector between these points is (1-0, -9-(-10), 0-0) = (1, 1, 0).
So a vector v parallel to the line is v = (1, 1, 0).
To find the coordinates of a point P on the line and a vector v parallel to the line, we first need to rewrite the given equation in a more standard form. The equation provided seems to be incorrect, but let's assume it's meant to be in the format of Ax + By = C, then we can proceed as follows:
1. Identify the normal vector of the line (A, B): Since the given equation is X - Y = 3 (combining the constants), the normal vector is (1, -1).
2. Determine the direction vector of the line, which is perpendicular to the normal vector. One possible direction vector is the one obtained by swapping the components and negating one of them, so v = (1, 1).
3. To find a point P on the line, we can choose a value for either x or y and solve for the other coordinate. Let's choose x = 0, then we have 0 - Y = 3, which gives Y = -3. Therefore, P(x, y) = (0, -3).
In summary, the point P on the line is (0, -3), and a vector v parallel to the line is (1, 1).

Suppose that Uranus rotates on its axis once every 17. 2 hours. The equator lies on a circle with a radius of 15,881 miles. (a) Find the angular speed of a point on its equator in radians per day (24 hours). (b) Find the linear speed of a point on the equator in miles per day. Do not round any intermediate computations, and round your answer to the nearest whole number. (a) Angular speed: radians per day (b) Linear speed : miles per day
Rounding to the nearest whole number, the linear speed of a point on Uranus' equator is approximately 139,424 miles/day.
(a) To find the angular speed of a point on Uranus' equator, we need to convert the rotation period from hours to days and then calculate the angle rotated in one day.
In one day (24 hours), Uranus rotates:
24 hours ÷ 17.2 hours/rotation ≈ 1.3953 rotations
The angle rotated in one day is:
1.3953 rotations × 2π radians/rotation ≈ 8.7674 radians/day
So the angular speed of a point on Uranus' equator is approximately 8.7674 radians/day.
(b) To find the linear speed of a point on Uranus' equator, we can use the formula:
linear speed = radius × angular speed
where the radius is given as 15,881 miles and the angular speed is 8.7674 radians/day (from part (a)).
Substituting these values, we get:
linear speed = 15,881 miles × 8.7674 radians/day ≈ 139,424 miles/day
Rounding to the nearest whole number, the linear speed of a point on Uranus' equator is approximately 139,424 miles/day.

In a nuclear disaster, there are multiple dangerous radioactive isotopes that can be detected. If 91.9% of a particular isotope emitted during a disaster was still present 6 years after the disaster, find the continuous compound rate of decay of this isotope
The decay of isotope at compound rate is approximately 0.0140.
To find the continuous compound rate of decay of this isotope, we can use the following formula:
Nₜ = N₀e^(-λᵗ)
Where:
Nₜ is the amount of the isotope present after time t (years),
N₀ is the initial amount of the isotope,
λ is the continuous compound rate of decay, and
t is the time in years.
In this case, 91.9% of the isotope is still present 6 years after the disaster,
so Nₜ = 0.919 * N₀, and t = 6 years.
We want to find λ, the continuous compound rate of decay.
We can rewrite the formula as follows:
0.919 * N₀ = N₀ * e^(-λ * 6)
Divide both sides by N₀:
0.919 = e^(-λ * 6)
Now, take the natural logarithm (ln) of both sides:
ln(0.919) = -λ * 6
Divide by -6 to solve for λ:
λ = ln(0.919) / (-6)
Calculate the value:
λ ≈ 0.0140
So, the continuous compound rate of decay of this particular radioactive isotope is approximately 0.0140.

find the coordinates of p so that p partitions the segment of AB in the ratio 7 to 2 if A( -5,4) and B( -8,-2)
The coordinates of p so that p partitions the segment of AB in the ratio 7 to 2 if A( -5,4) and B( -8,-2) is P(x, y) = [-22/3, -2/3].
How to determine the coordinates of point P?In this scenario, line ratio would be used to determine the coordinates of the point P on the directed line segment that partitions the segment into a ratio of 1 to 4.
In Mathematics and Geometry, line ratio can be used to determine the coordinates of P and this is modeled by this mathematical equation:
P(x, y) = [(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]
By substituting the given parameters into the formula for line ratio, we have;
P(x, y) = [(mx₂ + nx₁)/(m + n)], [(my₂ + ny₁)/(m + n)]
P(x, y) = [(7(-8) + 2(-5))/(7 + 2)], [(7(-2) + 2(4))/(7 + 2)]
P(x, y) = [(-56 - 10)/(9)], [(-14 + 8)/9]
P(x, y) = [-66/9], [(-6)/(9)]
P(x, y) = [-22/3, -2/3]

Here is a data set: 51, 47, 48, 51, 50, 8
Answer true or false for the following statements.
If you remove the outlier: 8
- the range will stay the same: false
- the mean will decrease: false
- the median will increase: true
The statements are classified as follows:
- the range will stay the same: false- the mean will decrease: false- the median will increase: true.How to obtain the features of the data-set?The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations, which is also called the cardinality of the data-set.
8 is a low outlier, hence it is a value lower than the mean, meaning that the mean increases if we remove the observation of 8.
The range of a data-set is calculated as the difference between the highest value and the lowest value in the data-set, thus if we remove the low value of 8, the next low value is of 47, meaning that the range decreases.
The ordered data-set is given as follows:
8, 47, 48, 50, 51, 51.
The data-set has an even cardinality of 6, hence the median is calculated as the mean of the two middle elements as follows:
Median = (48 + 50)/2
Median = 49.
Removing 8, the data-set is given as follows:
47, 48, 50, 51, 51.
Hence the median increases, as it will be the middle value of 50.

Suppose that the weekly profit, in dollars, of producing and selling x cars is P(x) = -0.005x*-0.2x2 + 1000x - 1300. and currently 80 cars are produced and sold weekly. Use P(80) and the marginal profit when x-SAP(80)) to estimate the weekly profit of producing and selling 81 cars. Round to the nearest dollar.
• $75,731 • $75,732 • $75,645 • $77,032
To estimate the weekly profit of producing and selling 81 cars, we first need to find the current weekly profit for producing and selling 80 cars using P(80):
P(80) = -0.005(80)^(2) - 0.2(80) + 1000(80) - 1300
P(80) = $75,800
Now we need to find the marginal profit at x = 80, which is the derivative of the profit function P(x):
P'(x) = -0.01x - 0.4x + 1000
P'(80) = -0.01(80) - 0.4(80) + 1000
P'(80) = $920
The marginal profit at x = 80 is $920. This means that for each additional car produced and sold beyond 80, the profit will increase by $920.
To estimate the weekly profit of producing and selling 81 cars, we can use the approximation formula:
ΔP ≈ P'(80)Δx
where ΔP is the change in profit, Δx is the change in the number of cars produced and sold, and P'(80) is the marginal profit at x = 80.
We want to find the change in profit when the number of cars produced and sold increases from 80 to 81, so Δx = 1. Plugging in the values we have:
ΔP ≈ $920(1)
ΔP ≈ $920
This means that the estimated weekly profit for producing and selling 81 cars is:
P(81) ≈ P(80) + ΔP
P(81) ≈ $75,800 + $920
P(81) ≈ $75,720
Rounding to the nearest dollar, the answer is $75,720. So the correct option is: $75,720.

Raymond wants to know the costs of buying different numbers of songs for his mp3 player. The cost of each song is the same.
To determine the cost of buying different numbers of songs for his mp3 player, Raymond needs to know the cost of a single song and the total number of songs he wants to buy, as well as consider bulk purchasing options like buying an album.
Assuming the cost of a single song is $1, if Raymond wants to buy 10 songs, the cost would be 10 x $1 = $10. Similarly, if Raymond wants to buy 20 songs, the cost would be 20 x $1 = $20. In general, the cost of buying n songs would be n x $1.
If the cost of a single song is not $1, then Raymond would need to adjust his calculations accordingly. For example, if the cost of a single song is $0.99, then the cost of buying 10 songs would be 10 x $0.99 = $9.90, and the cost of buying 20 songs would be 20 x $0.99 = $19.80.
Raymond could also consider purchasing songs in bulk, such as by buying an album, which typically offers a discounted price compared to purchasing individual songs. In this case, the cost of buying different numbers of songs would depend on the number of songs in the album and the cost of the album.

When angela and walker first started working for the supermarket, their weekly salaries totaled $550. now during the last 25 years walker has seen his weekly salary triple angela has seen her weekly salary become four times larger. together their weekly salaries now total $2000. write an algebraic equation for the problem. how much did they each make 25 years ago?
Angela made $350 per week 25 years ago and Walker made $200 per week 25 years ago.
Let's assign variables to represent Angela and Walker's salaries 25 years ago. Let A be Angela's salary 25 years ago and W be Walker's salary 25 years ago.
Using the information given in the problem, we can set up two equations:
A + W = 550 (their total salary 25 years ago)
4A + 3W = 2000 (their total current salary)
To solve for A and W, we can use substitution or elimination. Let's use substitution.
From the first equation, we can rearrange to solve for A:
A = 550 - W
Substitute this into the second equation:
4(550 - W) + 3W = 2000
Distribute the 4:
2200 - 4W + 3W = 2000
Simplify:
W = 800
Now that we know Walker's salary 25 years ago was $800, we can plug that into the first equation to solve for Angela's salary:
A + 800 = 550
A = -250
Uh oh, a negative salary doesn't make sense in this context. We made a mistake somewhere.
Let's go back to our original equations and try elimination instead:
A + W = 550
4A + 3W = 2000
Multiplying the first equation by 4, we get:
4A + 4W = 2200
Subtracting the second equation from this, we get:
W = 200
Now we can plug this into either equation to solve for A:
A + 200 = 550
A = 350
So Angela made $350 per week 25 years ago and Walker made $200 per week 25 years ago.

The arable land area of a commune is about 81. 5 ha. This year's summer-autumn crop, this commune intends to use 57 of these areas to grow rice. Calculate the area of the commune's summer-autumn rice crop (use a handheld calculator and then round the result to the third decimal place)
The area of the commune's summer-autumn rice crop is approximately 570,041.902 square meters. ( rounded to the third decimal place)
To calculate the area of the commune's summer-autumn rice crop, we need to multiply the total area of the commune by the percentage of the area used to grow rice.
First, we need to convert the area from hectares to square meters since the percentage is based on the total land area in square meters.
1 hectare = 10,000 square meters
So, 81.5 hectares = 81.5 x 10,000 = 815,000 square meters
Next, we can calculate the area of the rice crop:
57/81.5 = 0.699386503
0.699386503 x 815,000 = 570,041.902 square meters
Rounding to the third decimal place, the area of the commune's summer-autumn rice crop is approximately 570,041.902 square meters.
