Triangle PQR has the coordinates P(2,4), Q(-2,4), R(0,-5).
Write the coordinates of the vertices of the image of a triangle after a dilation of 2.
P' ___
Q' ___
R' ___

Write the arrow notation rule for the dilation, use (x,y) --->(___)

Answers

Answer 1

AnswerStep-by-step explanation:

dilation = multiply

so

P'= (2*2,4*2) Q'= (-2*2,4*2) R'= (0*2,-5*2)

P'=(4,8)         Q'= (-4,8)         R' = (0,-10)

(x,y) ----> (x*2,y*2)

Answers

Answer:

C

Step-by-step explanation:

To find the perimeter of a figure, all we have to do is add up the lengths of its sides. Therefore, the perimeter of this figure is:

\(x+x+1+x-4+x+3+x-2\\= (x+x+x+x+x)+(1-4+3-2)\\=5x-2\)

Describe how the data is dispersed in a box plot with the following data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

AND PLEASE ACTUALLY EXPLAIN/DESCRIBE!

Answers

In a box plot, also known as a box-and-whisker plot, the data is dispersed and represented visually to provide a summary of the distribution and key characteristics of the dataset. Let's describe how the data is dispersed in the box plot for the given data set: 25, 36, 21, 30, 20, 32, 38, 19, 36, 31, 26, 33, 27, 18, 24.

1. Median (Q2): The median represents the middle value of the dataset when arranged in ascending order. In this case, the median is around 27 or 28, as it lies between the values 27 and 30.

2. Lower Quartile (Q1): The lower quartile marks the boundary between the lower 25% of the data and the upper 75%. It is located approximately around 22 or 23, as it falls between the values 21 and 24.

3. Upper Quartile (Q3): The upper quartile marks the boundary between the lower 75% of the data and the upper 25%. It is located around 34 or 35, as it lies between the values 33 and 36.

4. Interquartile Range (IQR): The IQR is the range between the upper and lower quartiles (Q3 - Q1). In this case, the IQR is approximately 12 (35 - 23).

5. Whiskers: The whiskers represent the range of the data excluding any outliers. They extend from the lower quartile (Q1) to the minimum value and from the upper quartile (Q3) to the maximum value. However, in some cases, the whiskers can also be defined based on certain criteria, such as 1.5 times the IQR. Outliers, if present, are depicted as individual data points beyond the whiskers.

6. Outliers: Outliers are data points that significantly deviate from the rest of the dataset. In this case, there are no clear outliers based on the data provided.

7. Box: The box in the box plot spans from the lower quartile (Q1) to the upper quartile (Q3) and represents the middle 50% of the data. In this case, the box spans approximately from 23 to 35.

By observing the box plot, we can see that the data is moderately dispersed, with the majority of values concentrated around the median. The range of the data is approximately 20 to 38, with some variability within the dataset.

\(\huge{\mathfrak{\colorbox{black}{\textcolor{lime}{I\:hope\:this\:helps\:!\:\:}}}}\)

♥️ \(\large{\underline{\textcolor{red}{\mathcal{SUMIT\:\:ROY\:\:(:\:\:}}}}\)

To create a box plot for this data set, we need to find the minimum value, maximum value, median, and quartiles.

Minimum value: 18
First quartile (Q1): 22
Median: 29
Third quartile (Q3): 36
Maximum value: 38

The box plot is created using these values. A box is drawn from Q1 to Q3 with a line inside the box at the median. Whiskers are drawn from the box to the minimum and maximum values. Any data points beyond the whiskers are plotted as individual points.

In this box plot, the data is dispersed fairly evenly, with no outliers beyond the whiskers. The box is centered around the median, indicating that the data is roughly symmetric. The lower half of the data is slightly more spread out than the upper half, as indicated by the longer whisker on the left side of the box. Overall, the box plot shows that the data is relatively consistent, with no extreme values.

The first one: They are telling you that 1 inch = 1 foot, and the window width is already 4 inches so since your going to convert into feet then look at the “key” and think okay if 1 inch = 1 foot then how many feet does 4 inches equal it would be 4ft
The second question: It’s saying two cities are 5 3/4 inches apart and for every 1/2 inch = 3 miles so first you would take 5 3/4 and divide 1/2 you would get 11 1/2 but that’s not the answer that’s how many inches in all so you would take 11 1/2 and multiply 3 to get how many miles so the answer is 34 1/2 miles
I hope this helps I tried to explain as much as I can so you won’t have trouble on this kinda stuff again:))
The first one would be four feet and the second would be 34 and 1/2 miles

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

A cylindrical cake is made in a pan that has a diameter of 10
inches and a height of 2 inches. What is the total surface
area of the icing on the cake?

Answers

141.37 square inches

Answer:

  about 141.4 square inches

Step-by-step explanation:

You want the area of icing on a cake that is 10 inches in diameter and 2 inches high.

Icing

The icing on a cake covers the lateral surface area and the area of the circular top. In terms of diameter, the sum of those areas is ...

  icing area = πdh +(π/4)d² = πd(h +d/4)

  icing area = π(10 in)(2 in + (10 in)/4) = π(10 in)(4.5 in)

  icing area = 45π in² ≈ 141.4 in²

The area of icing on the cake is about 141.4 square inches.
