To determine the scale factor used to dilate polygon ABCD to A′B′C′D′, we can compare the corresponding side lengths.
The distance between A(1, 1) and B(3, 1) is 2 units, and the distance between A′(3, 3) and B′(9, 3) is 6 units, so the horizontal side has been scaled by a factor of 6/2 = 3.
Similarly, the distance between A(1, 1) and D(1, 2) is 1 unit, and the distance between A′(3, 3) and D′(3, 6) is 3 units, so the vertical side has been scaled by a factor of 3/1 = 3.
Since both scaling factors are equal to 3, the overall scale factor used to dilate the polygon is 3. Answer: 3.

Answer:
x = 19
Step-by-step explanation:
We can see that the angles (2x + 4) and (8x - 14) are supplementary — they add to 180. From this observation, we can form the equation that can be solved for x:
(2x + 4) + (8x - 14) = 180
↓ combining like terms
10x - 10 = 180
↓ adding 10 to both sides
10x = 190
↓ dividing both sides by 10
x = 19

Find the volume of the sphere below. Use the pi key on the calculator for pi, and round to the nearest tenth.
Answer: A: 1,767.1 Cubic centimeters
Step-by-step explanation:
The equation for the volume of a sphere is: [tex]V= \frac{4}{3} \pi r^{3}[/tex]
I simply plugged in the radius (r). Here is what my equation looks like now: [tex]V= \frac{4}{3} \pi 7.5^{3}[/tex]
I simply plugged this into my calculator, to get my answer of [tex]1,767.1cm^{3}[/tex]
Hope this helps!

What is the perimeter of this composite shape? ___ ft.
Use 3.14 for "pi" and round to the nearest hundredths place
Answer:
36.85 ft
Step-by-step explanation:
3 feet on either end + 6 feet on either side + circumference of the circle
3 + 3 + 6 + 6 + circumference of the circle
18 + circumference of the circle
You can find the circle's diameter by subtracting 6 from 12. You get 6. You can find the radius by dividing the diameter by 2. You get 3.
The formula for circumference is 2·π·Radius
2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85

Step-by-step explanation:
You have to first do the problem. If the tax is 2 and the total is 42, you would do 42 - 2. Then you have to divide it into 5. (the amount of items) You will get 8. Now you have to find what question is wrong. So if you would compare the way of figuring it out to the answers you would see that 5 is not how much each product cost. So c is the answer!

The length of a cell phone is 1.4 1.4 inches and the width is 4.2 4.2 inches. The company making the cell phone wants to make a new version whose length will be 1.75 1.75 inches. Assuming the side lengths in the new phone are proportional to the old phone, what will be the width of the new phone?
If the side lengths of the new phone are proportional to the old phone, then we can set up a proportion:
1.4/4.2 = 1.75/x
Solving for x, we get:
x = 5.25 inches
So the width of the new phone will be 5.25 inches.
Answer:
The answer is 5.25 inches!

Please help solve the quadratic equation
Answer: To use the calculator: Enter the corresponding values into the boxes below and ... to and add to. i) In a quadratic equation in the form ax2 bx c 0, if.
Step-by-step explanation:
According to the information, we can infer that some coordinates of this quadratic equation are: (-2, -3), (-1, -0.75), (0, 0), (1, -0.75), and (2, -3)
How to solve the quadratic equation?To solve the quadratic equation, we need to set the equation equal to zero:
-0.75x^2 = 0Now, we can divide both sides by -0.75 to isolate x^2:
x^2 = 0/(-0.75)x^2 = 0Taking the square root of both sides, we get:
x = 0Therefore, the solution to the quadratic equation s(x) = -0.75x^2 is x = 0.
According to the previous information, we can infer that the equation s(x) = -0.75x^2 represents a downward facing parabola. Here are 5 possible coordinates on this curve:

In the diagram of a fan below, CA = 9.5 in. this is the distance from the center to a point on the fans blade. what is the distance point A travels in one rotation of the fans blade
Answer:
About 59.66 inch
Step-by-step explanation:
To find the circumference you first have to find the diameter which is the double the radius. Since 9.5 is the radius of this circle, the diameter is, 9.5x2=19.
With the diameter of 19, you multiply the 19 with pie which is approximately 3.14. The answer is 19x3.14=59.66

You can't determine the mode because you would need the set list of numbers, and not just the box plot.
Answer:
unable to determine the given data
Step-by-step explanation:
What is mode?The mode is the value in a set that appears most often.
In order to identify the mode, we would need the set of numbers.
Because, we are only given the box plot, we cannot find the number that appares the most , so we are unable to determine the given data.

In the data set below, what is the interquartile range?
23 58 58 64 76 87
Answer: IQR= 18
Step-by-step explanation:
First, you need to put the numbers in order from least to greatest, which they already are.
23, 58, 58, 64, 76,87
then, you draw an imaginary line down the middle of the numbers (between 58 and 64), and then you find the number in the middle of these. The Q1 is 58, and the Q3 is 76. In order to find the Interquartile range (IQR), you simply subtract the two.
76-58= 18
And you have your answer
Hope this helps!
Answer:
44
Step-by-step explanation:
First, we need to find the median in the data set.
It's between 58 and 64. To find the median, we add those two numbers and then divide by 2.
58 + 64 = 122
122 ÷ 2 = 61 (Mark this point in between the numbers on the data set)
median = 61
23, 58, 58, | 64, 76, 87
Now that we have the median, we have to find the upper quartile and the lower quartile in order to find the interquartile range.
Lets find upper quartile first. In order to do that, add up all the numbers to the right of the data set from the median point, then divide by 2.
64 + 76 + 87 = 227
227 ÷ 2 = 113.5
The same goes for the lower quartile (to the left).
23 + 58 + 58 = 139
139 ÷ 2 = 69.5
Lastly, to find the interquartile range, simply subtract the lower quartile from the upper quartile.
113.5 - 69.5 = 44
Therefore interquartile range = 44.

Box and Whisker Plot
box plot
Description
A Box and Whisker Plot (or Box Plot) is a convenient way of visually displaying the data distribution through their quartiles.
The lines extending parallel from the boxes are known as the “whiskers”, which are used to indicate variability outside the upper and lower quartiles. Outliers are sometimes plotted as individual dots that are in-line with whiskers. Box Plots can be drawn either vertically or horizontally.
Although Box Plots may seem primitive in comparison to a Histogram or Density Plot, they have the advantage of taking up less space, which is useful when comparing distributions between many groups or datasets.
Here are the types of observations one can make from viewing a Box Plot:
What the key values are, such as: the average, median, 25th percentile, etc.
If there are any outliers and what their values are.
If the data is symmetrical or not.
How tightly is the data grouped.
If the data is skewed and if so, in what direction.
Two of the most commonly used variation of Box Plot are: variable-width Box Plots and notched Box Plots.

Answer:
-10.5
Step-by-step explanation:
Pick two points that the line overlaps. We can see the points are on (0,63) (2,42) and (4,21). Lets use (2,42) and (4,21). To find the rate of change (m) the formula needed is y^2 - y^1 divided by x^2 - x^1. 21-42=-12 over 4-2=2. So we get -10.5 for the rate of change.
Answer:
