Answer: Amplitude is 108 degrees
Step-by-step explanation:
To determine the amplitude of the tip of King Arthur's Sword, we need to understand the shape of the sword's blade, which consists of a regular hexagon and a regular pentagon.
A regular hexagon has six equal sides and six equal angles, each measuring 120 degrees. The regular pentagon, on the other hand, has five equal sides and five equal angles, each measuring 108 degrees.
Since the tip of the sword is formed by the meeting point of the hexagon and pentagon, it will be at the apex of the pentagon. The apex of the pentagon will have an angle of 108 degrees.

We have,
To test independence for the contingency table, we need to calculate the test statistic.
The most commonly used test statistic for testing independence in a 2x2 contingency table is the chi-square test statistic.
The chi-square test statistic (χ²) is calculated using the formula:
χ² = Σ [(Observed - Expected)² / Expected]
Where:
Σ represents the sum over all cells of the contingency table.
Observed is the observed frequency in each cell.
Expected is the expected frequency in each cell if the variables were independent.
First, we calculate the expected frequencies for each cell. To do this, we use the formula:
Expected frequency = (row total x column total) / grand total
Grand total = sum of all frequencies = 36 + 17 + 15 + 11 = 79
Expected frequency for the cell "Closed roof - Win" = (53 * 51) / 79 = 34.49
Expected frequency for the cell "Closed roof - Loss" = (53 * 28) / 79 = 18.51
Expected frequency for the cell "Open roof - Win" = (26 * 51) / 79 = 16.51
Expected frequency for the cell "Open roof - Loss" = (26 * 28) / 79 = 9.49
Now, we can calculate the test statistic using the formula:
χ² = [(36 - 34.49)² / 34.49] + [(17 - 18.51)² / 18.51] + [(15 - 16.51)² / 16.51] + [(11 - 9.49)² / 9.49]
Calculating each term and summing them up:
χ² ≈ 0.058 + 0.482 + 0.58 + 0.35 ≈ 1.47
Therefore,
The test statistic χ² is approximately 1.47.

Angle C of the triangle measures 68°.
Side AC = 22.90
Side BC = 14.26
Given triangle,
∠A = 37°
∠B = 75°
AB = 22
Now,
Sum of all the interior angles of triangle is 180.
So,
∠A + ∠B +∠C = 180°
37° + 75° + ∠C = 180°
∠C = 68°
Now,
According to sine rule,
Ratio of side length to the sine of the opposite angle is equal.
Thus,
a/SinA = b/SinB = c/SinC
Let,
BC = a
AC = b
AB = c
So,
a/Sin37 = b/Sin75 = c/Sin68
a/0.601 = b/0.965 = 22/0.927
Solving,
BC = a = 14.26
AC = b = 22.90
Thus with the properties of triangle side length and angles can be calculated.

The formulas that represent the linear function in this problem are given as follows:
y - 2 = 2/3(x - 1).y - 4 = 2/3(x - 4).f(x) = 2x/3 + 4/3.How to define a linear function?The slope-intercept equation for a linear function is presented as follows:
y = mx + b
The line has a slope of 2/3, hence:
y = 2x/3 + b.
When x = 1, y = 2, hence the intercept b is obtained as follows:
2/3 + b = 2
b = 6/3 - 2/3
b = 4/3.
Hence the slope-intercept equation of the line is given as follows:
f(x) = 2x/3 + 4/3.

There are books on a shelf. of these books are new. The rest of them are used. what is the ratio of used books to all books on the shelf?
Let's denote the total number of books on the shelf as 'total_books', and the number of new books as 'new_books'.
The number of used books can be calculated as the difference between the total number of books and the number of new books:
used_books = total_books - new_books
To find the ratio of used books to all books on the shelf, we divide the number of used books by the total number of books:
Ratio of used books to all books = used_books / total_books
Substituting the expression for used_books, we have:
Ratio of used books to all books = (total_books - new_books) / total_books
Simplifying further:
Ratio of used books to all books = 1 - (new_books / total_books)
Therefore, the ratio of used books to all books on the shelf is equal to 1 minus the ratio of new books to total books.

Solve (D ^ 2 - 6D + 9) * y = 0
The solution to the given differential equation is y(x) = (C1 + C2x) * e^(3x), where C1 and C2 are arbitrary constants.
To solve the given differential equation, we need to find the function y(x) that satisfies the equation:
(D^2 - 6D + 9)y(x) = 0,
where D represents the differentiation operator.
Let's break down the solution process step by step:
Characteristic Equation
First, we'll find the characteristic equation associated with the given differential equation. For a second-order linear homogeneous differential equation of the form aD^2y + bDy + cy = 0, the characteristic equation is obtained by replacing D with λ:
λ^2 - 6λ + 9 = 0.
Solving the Characteristic Equation
Now, we solve the characteristic equation to find the values of λ. Factoring the equation, we get:
(λ - 3)^2 = 0.
From this, we see that λ = 3 (with a multiplicity of 2).
General Solution
The general solution of the differential equation is given by:
y(x) = C1e^(λ1x) + C2xe^(λ2*x),
where C1 and C2 are arbitrary constants, and λ1, λ2 are the distinct roots of the characteristic equation.
In our case, since we have repeated roots, the general solution simplifies to:
y(x) = C1e^(3x) + C2xe^(3*x).

To determine the radius of each wheel, we can use the formula for the circumference of a circle:
Circumference = 2πr,
where "Circumference" represents the circumference of the wheel and "r" represents the radius of the wheel.
Given that the circumference of each wheel is 22 inches, we can set up the equation as follows:
22 = 2πr.
To solve for the radius, we'll isolate "r" by dividing both sides of the equation by 2π:
22 / (2π) = r.
Using a calculator for the approximation, we get:
r ≈ 3.5 inches.
Therefore, to the nearest length, the radius of each wheel is approximately 3.5 inches.

variable of 10(n+3)=1,000,00
Answer: Distribute the 10 on the left side of the equation:
10n + 30 = 1,000,000
Subtract 30 from both sides of the equation to isolate the term with n:
10n = 1,000,000 - 30
10n = 999,970
Divide both sides of the equation by 10 to solve for n:
n = 999,970 / 10
n = 99,997
Therefore, the value of the variable n that satisfies the equation 10(n + 3) = 1,000,000 is n = 99,997.

[tex](5 * x) mod 91 = 32[/tex]
The required reverse Euclidean algorithm is the solution to the modular equation (5x) mod 91 is
x = 6(mod 91).
Given that (5*x) mod 91 =32.
To solve the modular equation (5*x) mod 91 =32 using reverse Euclidean algorithm is to find the modular inverse of 5 modulo 91.
Consider (5*x) mod 91 =32.
5x = 32(mod 91)
Apply the Euclidean algorithm to find GCD of 5 and 91 is
91 = 18 * 5 + 1.
Rewrite it in congruence form,
1 = 91 - 18 *5
On simplifying the equation,
1 = 91 (mod 5)
The modular inverse of 5 modulo 91 is 18.
Multiply equation by 18 on both sides,
90x = 576 (mod91)
To obtain the smallest positive solution,
91:576 = 6 (mod 91)
Divide both sides by the coefficient of x:
x = 6 * 90^(-1).
Apply the Euclidean algorithm,
91 = 1*90 + 1.
Simplify the equation,
1 + 1 mod (90)
The modular inverse of 90 modulo 91 is 1.
Substitute the modular inverse in the given question gives,
x = 6*1(mod 91)
x= 6 (mod91)
Therefore, the solution to the modular equation (5x) mod 91 is
x = 6(mod 91).

As per the given data, the area of the rectangular field is approximately 204 square meters.
To find the area of the rectangular field, we need to multiply its length by its width.
Given that the length is 18 2/5 m and the width is 11 2/23 m, we need to convert these mixed fractions into improper fractions for easier calculation.
Length: 18 2/5 m = (5 * 18 + 2)/5 = 92/5 m
Width: 11 2/23 m = (23 * 11 + 2)/23 = 255/23 m
Now, we can calculate the area of the rectangular field:
Area = Length * Width
= (92/5) m * (255/23) m
= (92 * 255)/(5 * 23) m^2
= 23460/115 m^2
= 204 m^2 (rounded to the nearest whole number)

A truck travels from warehouse A at (–4,8) to warehouse B at (–4,–1). If each unit represents 20 miles per hour, how long will it take the truck to travel this distance?
It will take the truck 9 hours to travel from warehouse A to warehouse B.
To determine the time it takes for the truck to travel from warehouse A at (-4, 8) to warehouse B at (-4, -1), we need to calculate the distance between these two points and then convert it to time using the given unit of 20 miles per hour.
First, let's find the vertical distance between the two points. The y-coordinate of warehouse A is 8, and the y-coordinate of warehouse B is -1. So the vertical distance is 8 - (-1) = 9 units.
Next, we convert the vertical distance to miles. Since each unit represents 20 miles per hour, we multiply the vertical distance by 20: 9 units × 20 miles/unit = 180 miles.
Now, we can calculate the time it takes to travel this distance. We divide the distance by the speed of the truck, which is 20 miles per hour: 180 miles / 20 miles per hour = 9 hours.
Therefore, it will take the truck 9 hours to travel from warehouse A to warehouse B.
