Drag the tiles to the correct boxes to complete the pairs.
Match the pairs of coordinates with the distances between them.
Answers
The pairs of coordinates should be matched with the distances between them should be matched as follows;
Pairs Distance
(4, 2) and (1, -2) → 5 units.
(-8, 7) and (2, -3) → √200 units.
(9, 1) and (1, 9) → √128 units.
(-2, -6) and (-8, 2) → 10 units.
How to calculate the distance on coordinates?Mathematically, the distance between two (2) points that are on a coordinate plane can be calculated by using this formula:
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
For the ordered pairs (4, 2) and (1, -2), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(1 - 4)² + (-2 - 2)²]
Distance = √[(-3)² + (-4)²]
Distance = √(9 + 16)
Distance = √25
Distance = 5 units.
For the ordered pairs or points (-8, 7) and (2, -3), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(2 + 8)² + (-3 - 7)²]
Distance = √[(10)² + (-10)²]
Distance = √(100 + 100)
Distance = √200 units.
For the ordered pairs or points (9, 1) and (1, 9), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(1 - 9)² + (9 - 1)²]
Distance = √[(-8)² + (8)²]
Distance = √(64 + 64)
Distance = √128 units.
For the ordered pairs or points (-2, -6) and (-8, 2), we have;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance = √[(-8 + 2)² + (2 + 6)²]
Distance = √[(-6)² + (8)²]
Distance = √(36 + 64)
Distance = √100
Distance = 10 units.

Step-by-step explanation:
Answer:
1) 4 cm
2) 7cm
3) 8 1/6
Step-by-step explanation:

\(SA = 2(w*l)+2(w*h)+2(l*h)\)
\(228 = 2(9*6)+2(9*h)+2(6*h)\)
\(2(9*6)+2(9*h)+2(6*h) = 228\)
\(30h + 108 = 228\)
\(30h = 228-108\)
\(30h = 120\)

Answer:
1. m = 3x
2. Possibly doesn't have a constant rate of change, because if you were to multiply 4.9 to the other coordinates/points/x values provided, you would not get the correct value for y, this means that the rate of change is not constant. Not only that but if you are to find a value that can multiply and add up to each, it would not go with the first coordinate.
3. The constant rate of change is found to be: m = 0.375
Step-by-step explanation:
In the question, it is asking for the constant rate of change.
This can be found determined by the graphs:
x | y
5 | 15
8 | 24
12 | 36
24 | 72
From what is shown, on x's side, we can see that:
5 · 3 = 15
8 · 3 = 24
12 · 3 = 36
24 · 3 = 72
This means that the constant for the first graph is m = 3x.
x | y
2 | \(\frac{3}{4}\)
4 | \(1\frac{1}{2}\)
6 | \(2\frac{1}{4}\)
8 | 3
If you change the fractions into decimals:
\(\frac{3}{4}\) = 0.75
\(1\frac{1}{2}\) = 1.5
\(2\frac{1}{4}\) = 2.25
= 3.00
(The change is + 0.75)
0.75 + 0.75 = 1.5
1.5 + 0.75 = 2.25
2.25 + 0.75 = 3.00
(But what about multiplying it?)
It is found that 0.75 DOES NOT work with muliplying, BUT we can find the rate of change if we divide 0.75 by 2
\(\frac{0.75}{2}\) = 0.375
This would be your rate of change!

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

A right triangle is drawn on graph paper. The length of the legs measure 1.5 centimeters and 2 centimeters. The length of the hypotenuse measures 2.5 centimeters. Write an equation using the triangle’s side lengths to show the Pythagorean Theorem holds true for the triangle.
Answers
The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
In this case, let's denote the lengths of the legs as a = 1.5 centimeters and b = 2 centimeters, and the length of the hypotenuse as c = 2.5 centimeters.
The equation using the triangle's side lengths to show the Pythagorean Theorem holds true for the triangle is:
a^2 + b^2 = c^2
Substituting the given values, we have:
(1.5)^2 + (2)^2 = (2.5)^2
2.25 + 4 = 6.25
6.25 = 6.25
Therefore, the equation holds true, confirming that the Pythagorean Theorem is satisfied for the given right triangle.
