What is the area of the blue section?
Considering the area of the circles, the area of the blue section is of \(50\pi\) cm².
What is the area of a circle?
The area of a circle of radius r is given as follows:
\(A = \pi r^2\).
The area of the blue section is given by the area of the larger circle, of radius 10 cm, subtracted by the area of the two smaller circles, each with radius of 5 cm, hence:
\(A_G = \pi 10^2 = 100\pi\)
\(A_S = 2 \times \pi \times 5^2 = 50\pi\)
\(A_B = A_G - A_S = 100\pi - 50\pi = 50\pi\)
The area of the blue section is of \(50\pi\) cm².

The linear functions f(x) and g(x) are represented on the graph, where g(x) is a transformation of f(x):
A graph with two linear functions; f of x passes through 1, 3 and 3, 13, and g of x passes through negative 1, 3 and 1, 13.
Part A: Describe two types of transformations that can be used to transform f(x) to g(x). (2 points)
Part B: Solve for k in each type of transformation. (4 points)
Part C: Write an equation for each type of transformation that can be used to transform f(x) to g(x). (4 points)
Answer:
Part A: The two types of types of transformation are
1) Rotation of 11.3° about (1, 2)
2) By algebraic transformation
Part B:
Rotation by 11.3° and T(2 - y)×1/2 + x, 0)
Part C: The transformation that can be used to transform f(x) to g(x) is T(2 - y)×1/2 + x, 0)
Step-by-step explanation:
The coordinates through which the linear function f(x) passes = (1. 3) and (3, 13)
The coordinates through which the linear function g(x) passes = (1, 3) and (1, 13)
The equation for f(x) in slope and intercept form. y = m·x + c is given as follows;
The slope, m = (13 - 3)/(3 - 1) = 5
The equation in point and slope form is y - 3 = 5×(x -1)
y = 5·x - 5 + 3 = 5·x - 3
y = 5·x - 3
The equation for g(x) in slope and intercept form. y = m·x + c is given as follows;
The slope, m = (13 - 3)/(1 - 1) = ∞
∴ The equation in point and slope form is x = 1
Therefore, the two equations meet at the point (1, 2)
The transformation that can be used to transform f(x) to g(x) is T(2 - y)×1/2 + x, 0)
2) Another transformation that can be used is to rotate f(x) by the vertex angle as follows
Vertex angle is 90° - tan⁻¹(m) = 90° - tan⁻¹(5) ≈ 11.3°
Rotation of f(x) by 11.3° about (1, 2) gives g(x)

Sally made a profit of $2500 after selling stocks for $19000 after 2.5 years. What was her average annual percentage gain?
13.25%
6.06%
3.78%
Sally's average annual percentage gain is approximately 5.26%.
To calculate Sally's average annual percentage gain, we can use the formula:
Average Annual Percentage Gain = (Profit / Initial Investment) * (1 / Time) * 100
Profit = $2500
Initial Investment = $19000
Time = 2.5 years
Substituting the values into the formula:
Average Annual Percentage Gain = (2500 / 19000) * (1 / 2.5) * 100
= (0.1316) * (0.4) * 100
= 5.26

A recent General Social Survey asked respondents how many close friends they had. For a sample of 1467 people, the mean was 7.4 and the standard deviation was 11.0. The distribution had a median of 5 and a mode of 4.Based on these statistics, would you expect this distribution to be bell-shaped, left skewed, or right skewed?
Answer:
This distribution should be expected to be right skewed.
Step-by-step explanation:
Pearson skewness:
The skewness of a data set is given by the subtraction of the mean by the mode, divided by the standard deviation.
If the coefficient is positive, the distribution is right skewed.
If the coefficient is negative, the distribution is left skewed.
If the coefficient is sufficiently close to 0(+/- 0.05), the distribution is bell shaped.
In this question:
Mean 7.4, mode 4, standard deviation 11
(7.4-4)/11 = 3.4/11 = 0.31
Positive coefficient, so right skewed.

Rotate this image 180° clockwise around the point (–2, 1):
The rotation of the image given 180° clockwise around the point (-2, 1) gives the image in the second option.
What is Rotation?Rotation is a kind of geometric transformation where a figure or point is rotated by a certain degrees about a given point.
The coordinates of the given image are :
(-1, 1), (-2, 1), (-1, 4) and (-2, 4).
Point of rotation is (-2, 1).
The points are not rotated around the origin.
To make it seem like around the origin, subtract the point of rotation from the points.
So the new points are :
(1, 0), (0, 0), (1, 3) and (0, 3)
Now rotate the image with the new coordinates around the origin 180° clockwise.
Rotation is -180°, which is equivalent to rotation of 180° counterclockwise.
Coordinates (x, y) when rotated 180° clockwise becomes (-x, -y).
New coordinates after rotation about origin are :
(-1, 0), (0, 0), (-1, -3) and (0, -3).
Now add the point of rotation (-2, 1) again.
Points are :
(-3, 1), (-2, 1), (-3, -2) and (-2, -2).
Image with these points is the second option.

the solid with a semicircular base of radius 6 whose cross sections perpendicular to the base and parallel to the diameter are squares
The volume of the solid is 432 cubic units.
Let's consider a typical cross-section of the solid at a distance x from the center of the base. This cross-section is a square, with side length equal to the height of the semicircle at that distance from the center, which is:
h = √(6^2 - x^2)
The volume of this cross-section is then V(x) = h^2 * dx, where dx is the thickness of the solid at this point. To find the total volume of the solid, we need to integrate V(x) over the range of x values that covers the entire base of the solid, which is from -6 to 6 (half of the diameter of the semicircle):
V = ∫₋₆⁶ V(x) dx
= ∫₋₆⁶ (√(6^2 - x^2))^2 dx
= ∫₋₆⁶ (36 - x^2) dx
= [36x - (1/3)x^3] from x=-6 to x=6

In a survey, people were asked whether they like baseball or whether they like hockey. Here are the results: Likes hockey Doesn’t like hockey Likes baseball 12 18 Doesn’t like baseball 14 6 What value is missing to convert the two-way table to a two-way relative frequency table? Likes hockey Doesn’t like hockey Likes baseball 0.24 0.36 Doesn’t like baseball 0.28
The missing value 'x' in the two-way relative frequency table is 0.36.
To convert the two-way table to a two-way relative frequency table, we need to calculate the relative frequencies for each category. Relative frequency is calculated by dividing the frequency of a particular category by the total count in that row or column.
Let's denote the missing value as 'x'. To find the value of 'x', we need to ensure that the sum of the relative frequencies in each row and each column adds up to 1.
First, let's calculate the relative frequencies for each category:
Likes hockey: The total count in this row is 12 + 18 = 30.
Relative frequency of "Likes hockey" = 12/30 = 0.4
Relative frequency of "Doesn't like hockey" = 18/30 = 0.6
Likes baseball: The total count in this column is 12 + 14 = 26.
Relative frequency of "Likes baseball" = 12/26 ≈ 0.4615
Relative frequency of "Doesn't like baseball" = 14/26 ≈ 0.5385
To ensure that the relative frequencies add up to 1, we can set up the following equations:
0.4 + x = 1 (sum of relative frequencies in the "Likes hockey" row)
0.4615 + 0.5385 + x = 1 (sum of relative frequencies in the "Likes baseball" column)
Simplifying the equations, we have:
x = 0.6 (1 - 0.4) = 0.6 * 0.6 = 0.36

x and y have the values 7 and 7√2, respectively.
The sides of a right triangle with 45-degree acute angles have a unique ratio of 1:1:2.
We can use this information to determine the values of x and y because the base is specified as being 7.
Let's give the perpendicular side the value of x, and the hypotenuse the value of y.
The perpendicular side (x) and the base (7) have the same length because the acute angles are both 45 degrees.
Consequently, x = 7.
We can determine that x:y:2x using the ratio of 1:1:2.
When we enter the value of x, we may calculate y:
7:y:√2(7)
