What is dilation?

In Geometry, dilation can be defined as a type of transformation which typically changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

Next, we would have to dilate the coordinates of the preimage by using a scale factor of 3/5 centered at the origin as follows:

Ordered pair A (-4, 6) → Ordered pair A' (-4 × 3/5, 6 × 3/5) = Ordered pair A' (-2.4, 3.6).

Ordered pair B (-2, 2) → Ordered pair B' (-2 × 3/5, 2 × 3/5) = Ordered pair B' (-1.2, 1.2).

Ordered pair C (4, -2) → Ordered pair C' (4 × 3/5, -2 × 3/5) = Ordered pair C' (2.4, -1.2).

A. The number on the opposite side of the equals side from the variable

B. The number furthest from the variable (but on the same side of the equals sign)

C. order doesnt matter - choose which you want to do first

D. the number touching the variable

Answers

Answer:

C. Order doesnt matter - choose which you want to do first

Step-by-step explanation:

When solving multi step equations, there are different steps that can be followed depending on the nature of the equation. There could be variables on only one side or both sides of the equation and that can affect the order of operations. Thus, there is no standard order.

For example let's consider the equation;

7y + 6 = 2y + 16

Now,we can see there are variables on both sides, so the first step would be either to take the constants to one side first or to take the unknown variables to one side.

Whereas, in another example say;

5x - 3 = 7

The only option here is to take the constant on the left side to the right side.

There are other examples where we may have to carry out a division of all terms as the first step. In some other cases, there may be brackets, we need to get rid of as the first step.

Thus, there is no standard order and as such we choose which order we want to use based on the nature of the equation.

B. 2.19 units
C. 4.81 units
D. 4.90 units

Answers

The distance between the point (5,12) and the line y = 5x + 12 is 4.90 units

How to find the distance between a point and a line?

If a point P with the coordinates (x₁, y₁), and we need to know its distance from the line represented by ax + by + c = 0

Then the distance of a point from the line is given by the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

Given: the point (5,12) and the line y = 5x + 12. The line can be written as

5x-y+12 = 0. Thus:

x₁ = 5, y₁ = 12, a = 5, b = -1, c = 12. Substitute these into the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

d = (5×5 + (-1×12) + 12) / √(5² + (-1)²)

d = 25/√26 = 4.90 units

Therefore, the distance between the point and the line is 4.90 units. Option D is the answer

Many investors use interest-only loans to buy shares or property. For such loans the principal stays constant and only the interest is paid back each month.


She buys an investment property for $300 000 and borrows the full amount at 7% p.a. simple interest. She rents out the property at $1500 per month and pays $3000 per year in rates and other costs to keep the property.


Find the amount of interest she needs to pay back every month.


Find her yearly income from rent.



By considering the other costs in keeping the property, calculate her overall loss in a year.



she hopes that the property’s value will increase enough to cover any loss she is making. By what percentage of the original price will the property need to increase in value per year?

Answers

Step-by-step explanation:

to find the interest she needs to pay back every month, we need to use this formula:

I = PRT/12

in this case the principle is $300,000, the rate is 7% p.a. and the amount of time is 1 year, if we substitute in our values we:

I = (300,000)(7)(1)/12 = $17,500 in interest every month

to find her yearly income from rent, we have to multiply the monthly rent by 12

1500 × 12 = $18,000

to calculate her loss percentage in a year, we have to subtract 18,000 from 3000 which is 15,000

she said that she hopes the property's value will increase to cover the loss she made.

to cover the loss of $15000 per year, the property needs to increase in value by at least $15000. the percentage increases value can be written as

Percentage increase = (difference in increase/Original price) × 100

so

percentage increase = (15000/300000) × 100 = 5%

so the property needs to increase in value by at least 5% per year to cover the loss.

Final answer:

The woman needs to pay $1750 monthly as interest. Her yearly income from the rent is $18,000. After considering all other costs, she is at a loss of $6000 per year, so the property needs to increase in value by 2% per year to cover this loss.

Explanation:First, let's calculate the monthly interest she needs to pay. 7% of $300,000 is $21,000 for a year. To find the monthly interest, we divide this by 12, resulting in $1750.Her yearly income from rent is $1500 multiplied by 12, giving us $18,000.To calculate her overall loss, we add the yearly interest and the costs to keep the property, then subtract the yearly rent income. So, $21,000 + $3000 - $18,000 = $6000 loss per year.Lastly, to find out by what percentage the property value needs to increase, we divide the loss by the original price and multiply by 100, giving us 2% increase per year.Learn more about Interest and Profit Calculation here:

Write an equation to represent the function.

Damon joins a video game membership service. The lifetime membership fee is $50. The first video game is free, then any video game purchased after that is $25.

Answers

Hey mate. Here is your Answer:
f(x) = 50 + 25(x - 1)
Step-by-step explanation:
Let's write an equation to represent the function that will allow Damon to calculate the cost of his video game membership service:
Lifetime membership fee = $ 50
First video game is free
Then any video game purchased after = $ 25.
Let x to represent the total cost of the video game membership service, in consequence we can write the equation this way:
f(x) = 50 + 25(x - 1)
If x = 1, then f(1) = 50 + 0 = 50
If x = 2, then f(2) = 50 + 25 = 75
If x = 5, then f(5) = 50 + 100 = 150

Answers

The three (3) statements which are true include the following:

A. The radius of the circle is 3 units.

B. The center of the circle lies on the x-axis.

D. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.

What is the equation of a circle?

In Mathematics, the standard form of the equation of a circle is represented by this mathematical expression;

(x - h)² + (y - k)² = r²   ....equation 1.

Where:

h and k represents the coordinates at the center of a circle.

r represents the radius of a circle.

From the information provided above, we have the following equation of a circle:

x² + y² – 2x – 8 = 0      ......equation 2.

In order to determine the true statements, we would rewrite the equation in standard form and then factorize by using completing the square method:

x² – 2x + y² = 8 = 0

x² – 2x + (2/2)² + y² = 8 + (2/2)²

x² – 2x + 1 + y² = 8 + 1

(x – 1)² + (y - 0)² = 9         .......equation 3.

Comparing equation 1 and equation 3, we have the following:

Center (h, k) = (1, 0)

Radius (r) = 3

Additionally, this line and the center of the given circle lies on the x-axis (x-coordinate) because the y-value is equal to zero (0).

(x – 0)² + (y - 0)² = 3²

x² + y² = 9.

[9]​

Answers

Step-by-step explanation:

Let's solve the given questions step by step:

1. Determine the equation of f:

From the given information, we know that the turning point of f is (1, 4). The general form of a quadratic function is f(x) = ax^2 + bx + c. We are given that f(x) = a(x + p)^2 + q, so let's substitute the values:

f(x) = a(x + p)^2 + q

Since the turning point is (1, 4), we can substitute x = 1 and f(x) = 4 into the equation:

4 = a(1 + p)^2 + q

This gives us one equation involving a, p, and q.

2. Determine the equation of g:

The equation of g is given as g(x) = 0.3x + p1.

3. Determine the coordinates of the x-intercept of g:

The x-intercept is the point where the graph of g intersects the x-axis. At this point, the y-coordinate is 0.

Setting g(x) = 0, we can solve for x:

0 = 0.3x + p1

-0.3x = p1

x = -p1/0.3

Therefore, the x-intercept of g is (-p1/0.3, 0).

4. For which values of x will f(x) ≥ g(x)?

To determine the values of x where f(x) is greater than or equal to g(x), we need to compare their expressions.

f(x) = a(x + p)^2 + q

g(x) = 0.3x + p1

We need to find the values of x for which f(x) ≥ g(x):

a(x + p)^2 + q ≥ 0.3x + p1

Simplifying the equation will involve expanding the square and rearranging terms, but since the equation involves variables a, p, and q, we cannot determine the exact values without further information or constraints.

To summarize:

We have determined the equation of f in terms of a, p, and q, and the equation of g in terms of p1. We have also found the coordinates of the x-intercept of g. However, without additional information or constraints, we cannot determine the exact values of a, p, q, or p1, or the values of x for which f(x) ≥ g(x).

Coworkers Jan and Richard purchase lunch from food truck. Jan buys 1 beef taco and 2 fruit cups for $5.25. Richard buys 3 beef tacos and 1 fruit cup for $8.25. Find the price of each item (beef taco, fruit cup)

Answers

Given:

Jan buys 1 beef taco and 2 fruit cups for $5.25.

Richard buys 3 beef tacos and 1 fruit cup for $8.25.

Required:

We need to find the price of each item beef taco and fruit cup.

Explanation:

Let x be the price of a beef taco.

Let y be the price of a fruit cup.

The cost of 1 beef taco and 2 fruit cups = $ 5.25

\(x+2y=5.25\)

Subtract 2y from both sides of the equation.

\(x+2y-2y=5.25-2y\)\(x=5.25-2y\)

The cost of 3 beef tacos and 1 fruit cup = $ 8.25

\(3x+y=8.25\)

\(Substitute\text{ }x=5.25-2y\text{ in the equation.}\)

\(3(5.25-2y)+y=8.25\)\(15.75-6y+y=8.25\)\(15.75-5y=8.25\)

Add 5y- 8.25 to both sides of the equation

\(15.75-5y+5y-8.25=8.25+5y-8.25\)\(7.5=5y\)

Divide both sides by 5.

\(\frac{7.5}{5}=\frac{5y}{5}\)\(1.5=y\)

\(Substitute\text{ }y=1.5\text{ in the equation }x=5.25-2y.\)

\(x=5.25-2(1.5)\)\(x=2.25\)

Final answer:

The price of a beet taco is $ 2.25.

The price of a fruit cup is $ 1.50.

Answer:

20 blogs

Step-by-step explanation:

Step 1:  Determine the proportion of pop culture blogs:

First, we need to determine the proportion of pop culture blogs already written.  We can do this by dividing the number of pop culture blogs already written by the total number of blogs written:

The proportion of pop culture bloggers = Number of pop culture bloggers / Total number of bloggers

Proportion =  26 / (20 + 26 + 7 + 12)

Proportion = 26 / 65

Proportion = 0.4

Step 2:  Multiply the proportion of pop culture blogs by the number of upcoming blogs:

To determine the expected number of pop culture blogs that will be written given the data, we can multiply the proportion of pop culture blogs already written by the number of upcoming blogs:

Expected number of pop culture blogs = proportion of pop culture blogs *  number of upcoming blogs

Expected number = 0.4 * 50

Expected number = 20

Thus, you should expect 20 pop culture blogs to be written given the data.

Find the equation of a line with a slope of 13/2
that passes through the point (−2, — 10).

Answers

Answer:  \(y=\frac{13}{2} x+3\)

Step-by-step explanation:

Remember the point-slope equation which is \(y-y_{1} = m(x-x_{1} )\)  where\((x_{1} , y_{1} )\) is your point and \(m\) is your slope.

Given that we substitute what you have:

\(y-(-10) =\frac{13}{2} (x - (-2))\)

Minus and minus give us positive:

\(y+10 =\frac{13}{2} (x +2)\)

Multiply slope into the parenthesis:

\(y+10= \frac{13}{2}x + \frac{13}{2}*2\\\)

Calculate it:

\(y+10= \frac{13}{2}x +13\)

Isolate the \(y\) by subtracting 10 from both sides:

\(y=\frac{13}{2} x + 13 -10\)

Your final equation is:

\(y=\frac{13}{2} x +3\)

Hope this makes sense!

And here's the graph to prove that the line actually goes through the point \((-2,-10)\):

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution.

Probability is a measure of how likely something is to occur. Calculating probability involves dividing the total number of outcomes by the number of possible ways an event may occur.

Given that,

A fair coin is tossed = 8 time.

We have to find the probability of getting at least 6 heads.

Since, the probability of getting head, when one coin is tossed = 1/2

And the probability of getting tale = 1/2  

The probability of getting head at least  6 times when coin is tossed 8 times can be given as,

The head can come 6 times, then probability = \((1/2)\x^{6} (1/2)\x^{2}\) =  (1/2)⁸

The head can come 7 times, then probability = (1/2)⁷(1/2) = (1/2)⁸

The head can come 8 times, then probability = (1/2)⁸

The probability of getting head at least 6 times

= (1/2)⁸ + (1/2)⁸ +  (1/2)⁸ = 3(1/2)⁸ = 3/256 = 0.0117

The probability of getting at least 6 heads is3/256 or 0.0117

omplete the paragraph proof.

Given: and are right angles

Line segment A B is-congruent-to line segment B C Line segment B C is-congruent-to line segment A C

Prove: Line A R bisects Angle B A C

Triangles A B R and R C A share side R A. A line is drawn from point B to point C and intersects side A R at point P.

It is given that and are right angles, and . Since they contain right angles, ΔABR and ΔACR are right triangles. The right triangles share hypotenuse , and reflexive property justifies that . Since and , the transitive property justifies . Now, the hypotenuse and leg of right ΔABR is congruent to the hypotenuse and the leg of right ΔACR, so by the HL congruence postulate. Therefore, ________ by CPCTC, and bisects by the definition of bisector.




Answers

The BR is the perpendicular bisector of AC by CPCTC (corresponding parts of congruent triangles are congruent).

Based on the given information that angles ABR and ACR are right angles, and AB = AC, we can conclude that triangles ABR and ACR are right triangles.

Using the shared hypotenuse AR and the reflexive property, we can determine that side AB is congruent to side AC.

With this information, the transitive property allows us to conclude that angle BAR is congruent to angle CAR. Next, using the HL congruence postulate, we can prove that triangle ABR is congruent to triangle ACR.

This means that side BR is congruent to side CR, and angle BAC is bisected by line segment BR by the definition of bisector.

Answers

Answer:

It means in the middle of things, and Homer uses it in the Odyssey at the beginning of the epic because the story starts after the  Trojan War but before Ulysses gets back home.

Explanation:

Media res is a Latin phrase that means a situation where the narration starts in the middle of the story. In simple words, it means when a speaker talks about a story, starting with the middle of the plot but before the ending.

Likewise, Homer used this technique in his epic narrative story The Odyssey when he starts the story after the Trojan War and in the middle of the journey bur before the culmination of the story. Media res allows the middle of the plot to be the starting point and then gradually go back and forth in the narration between the past and the current/ situation.

Thus, the correct answer is the last or fourth option.

Suppose a random variable, x, follows a Poisson distribution. Let μ = 2.5 every minute, find the P(X ≥ 125) over an hour. Round answer to 4 decimal places.

Answers

Answer:

P(X ≥ 125) = 0.9812

Step-by-step explanation:

To solve this question, we need to understand the Poisson distribution and the normal distribution.

Poisson distribution:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

\(P(X = x) = \frac{e^{-\lambda}*\lambda^{x}}{(x)!}\)

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\(\lambda\) is the mean in the given interval, which is the same as the variance.

Normal distribution:

When the distribution is normal, we use the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the zscore of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

The Poisson can be approximated to the normal, with \(\mu = \lambda, \sigma = \sqrt{\lambda}\)

Let μ = 2.5 every minute

This is the mean of the Poisson, so \(\lambda = 2.5n\), in which n is the number of minutes.

P(X ≥ 125) over an hour

An hour has 60 minutes, so \(n = 60, \lambda = 2.5*60 = 150, \sigma = \sqrt{150} = 12.25\)

Using continuity correction, this is \(P(X \geq 125 - 0.5) = P(X \geq 124.5)\), which is 1 subtracted by the pvalue of Z when X = 124.5. So

\(Z = \frac{X - \mu}{\sigma}\)

\(Z = \frac{124.5 - 150}{12.25}\)

\(Z = -2.08\)

\(Z = -2.08\) has a pvalue of 0.0188

1 - 0.0188 = 0.9812

So

P(X ≥ 125) = 0.9812

Assignment For this assignment, you will write a program that plays the other side of the game "I'm thinking of a number" from Classwork 6. This time, the user is thinking of a number and your program will "guess". The loop is the part of your program which "knows" that the user's number is between lowEnd and highEnd inclusively. Initially, lowEnd is 1 and highEnd is 100. Each time your program "guesses" the number half-way between lowEnd and highEnd. If the new guess is low, then the new guess becomes the new lowEnd. If the new guess is high, then the new guess becomes the new highEnd. Example Compilation and Execution 1$ gcc -Wall guess.c $ ./a.out 11 Think of a number between 1 and 100.

This file contains the main program for . . You must use a do-while loop in your program which terminates when the program guesses the user's number or when it detects cheating. You can detect cheating when the player doesn't say Y even though your program is sure that it has the correct number (since lowEnd equals highEnd). To read in a single character typed in by the user (e.g., the letter y), use the same command you did for Homework 5: scanf("%c%c", &reply, &cr); Notice that in the starting point file there are two #defines, LOW and HIGH. These are constant values for the min and max of the range that the user's secret number is supposed to be. To help with debugging, and to help you see what is happening with your do-while loop, print out the values of lowEnd and highEnd inside the do-while loop. Then comment out the print statement in your final version. How are House seats reapportioned every 10 years?
