((x/y)^(n+1)) > ((x/y)^n) for all n ≥ 1 and x > y > 0.
To prove this statement by induction, we will use the principle of mathematical induction.
Base case: When n = 1, we have:
((x/y)^(1+1)) = ((x/y)^2) = (x^2)/(y^2)
((x/y)^1) = (x/y)
Since x > y > 0, we have x/y > 1. Therefore, (x^2)/(y^2) > (x/y), which means that the base case is true.
Inductive step: Assume that ((x/y)^(k+1)) > ((x/y)^k) for some arbitrary positive integer k. We want to prove that this implies that ((x/y)^(k+2)) > ((x/y)^(k+1)).
Starting with ((x/y)^(k+2)), we can write:
((x/y)^(k+2)) = ((x/y)^(k+1)) * ((x/y)^1)
Using the induction hypothesis, we know that ((x/y)^(k+1)) > ((x/y)^k), and we also know that x/y > 1. Therefore, we have:
((x/y)^(k+2)) > ((x/y)^k) * (x/y)
Simplifying this expression, we get:
((x/y)^(k+2)) > ((x/y)^k) * (x/y)
((x/y)^(k+2)) > ((x^k)/(y^k)) * (x/y)
((x/y)^(k+2)) > ((x^(k+1))/(y^(k+1)))
Therefore, we have shown that ((x/y)^(k+2)) > ((x/y)^(k+1)) for all positive integers k, which completes the inductive step.
By the principle of mathematical induction, we have proven that ((x/y)^(n+1)) > ((x/y)^n) for all n ≥ 1 and x > y > 0.

The total surface area of the square pyramid is 39 ft².
What is the total surface area?The total surface area of a square pyramid can be determined by adding the area of the lateral surfaces and the base together. A square pyramid has four lateral sides and one base.
Total surface area= area of the base + area of the lateral sides
Area of the base = area of a square = length² = 3² = 9 ft²
Area of the lateral sides = 2 x base x height
2 x 3 x 5 = 30 ft²
Total surface area = 30 + 9 = 39 ft²

What is proportion?Proportion is a statement that two ratios are equal. A ratio is a comparison of two quantities and is written in the form of a fraction. A proportion can be written in the form of a:b = c:d, where a, b, c, and d are numbers. This means that the ratio of a to b is equal to the ratio of c to d. We can also write a proportion as a fraction, where the numerator is the product of the means (ad) and the denominator is the product of the extremes (bc). Proportions are commonly used in mathematics to solve problems involving ratios and rates.
Here,
Since the floral design is made up of yellow and red hexagonal tiles, we need to determine the proportion of yellow tiles and red tiles in the design. Let's assume that the design consists of x yellow tiles and y red tiles. Each flower in the design consists of 7 hexagonal tiles - 6 yellow tiles and 1 red tile. Therefore, the total number of tiles in the floral design is:
Total number of tiles = 57 flowers x 7 tiles per flower
Total number of tiles = 399 tiles
Since each flower consists of 6 yellow tiles and 1 red tile, the total number of yellow tiles in the design is:
Number of yellow tiles = 6 x Number of flowers
Number of yellow tiles = 6 x 57
Number of yellow tiles = 342
Similarly, the total number of red tiles in the design is:
Number of red tiles = 1 x Number of flowers
Number of red tiles = 1 x 57
Number of red tiles = 57

Solve this system of linear equations. Separate
the x- and y-values with a comma.
9x - 19y = 74
3x + 3y = 6
Step-by-step explanation:
We can start by solving the second equation for one of the variables. Let's solve for y:
3x + 3y = 6
3y = 6 - 3x
y = 2 - x
Now we can substitute this expression for y into the first equation:
9x - 19y = 74
9x - 19(2 - x) = 74 (substituting y = 2 - x)
9x - 38 + 19x = 74
28x = 112
x = 4
Now we can use this value to find y:
y = 2 - x
y = 2 - 4
y = -2
Therefore, the solution to the system of equations is x = 4 and y = -2.

The area of this home plate is equal to 216.5 in².
How to determine the area of home plate?In order to determine the area of home plate, we would have to apply the law of cosine:
C² = A² + B² - 2(A)(B)cosθ
Where:
A, B, and C represent the length of side or side length of a given triangle.
By substituting the given side lengths and angle into the law of cosine formula, we have the following;
C² = A² + B² - 2(A)(B)cosθ
17² = 12² + 12² - 2(12)(12)cosθ
284 = 144 + 144 - 288cosθ
1 = -288cosθ
cosθ = (-1/288)
θ = 90.199
For the area of home plate, we have:
Area of home plate = Area of rectangle + Area of triangle
Area of home plate = 17(8.5) + 1/2(12)(12)sin90.199
Area of home plate = 144.5 + 72(0.9999940)

A box with a square base and open top must have a volume of 13,500 cm^3. Find the dimensions of the box (in cm) that minimize the amount of material used.
There are 2 answer, the height and the sides of the base.
Let the side length of the square base be x cm and the height of the box be h cm. Then the volume of the box is given by:
V = x^2 * h = 13,500 cm^3
We want to minimize the amount of material used, which is the surface area of the box. The surface area A is given by:
A = x^2 + 4xh
We can use the volume equation to solve for h in terms of x:
h = 13,500 / x^2
Substituting this into the surface area equation gives:
A = x^2 + 4x(13,500 / x^2) = x^2 + 54,000 / x
To minimize A, we take the derivative with respect to x and set it equal to zero:
dA/dx = 2x - 54,000 / x^2 = 0
Solving for x, we get:
x^3 = 27,000
x = 30
Substituting this back into the volume equation gives:
h = 13,500 / (30^2) = 15
Therefore, the dimensions of the box that minimize the amount of material used are 30 cm by 30 cm by 15 cm.

det(A - λI) = (1-λ)[(3-λ)(-λ) - (-1)(6)] - 0[2(-λ) - (-1)(0)] + (-1)[2(6) - (3-λ)(0)]
det(A - λI) = (1-λ)(λ² - 3λ - 6) - (-1)(12) = λ³ - 4λ² - 3λ + 14
Hence, the characteristic polynomial of A is λ³ - 4λ² - 3λ + 14.
The eigen values is the solution of the polynomial.
Using the rational roots of polynomial we have:
λ³ - 4λ² - 3λ + 14. factors as (λ-2)(λ-1)(λ-7)
Hence, the eigenvalues of A are 2, 1, and 7.

Solve
We can use the method of integrating factors to solve the equation.
Y' + x = (x-1)y' + 1
How can we use the integrating factors method here?The integrating factor method is a technique used to solve linear first-order ordinary differential equations.
Find the integrating factor:
The integrating factor is given by:
I(x) = e^(∫x dx) = e^(x^2/2)
Multiply both sides of the equation by the integrating factor I(x)
e^(x^2/2)Y' + xe^(x^2/2) = (x-1)e^(x^2/2)y' + e^(x^2/2)
Let's simplify the left-hand side using the product rule of differentiation
(d/dx)(e^(x^2/2)Y) = e^(x^2/2)Y' + xe^(x^2/2)
Rewrite the equation using the simplified left-hand side
(d/dx)(e^(x^2/2)Y) = (x-1)e^(x^2/2)y' + e^(x^2/2)
Then, Integrate both sides with respect to x
∫(d/dx)(e^(x^2/2)Y) dx = ∫((x-1)e^(x^2/2)y' + e^(x^2/2)) dx
e^(x^2/2)Y = ∫((x-1)e^(x^2/2)y' + e^(x^2/2)) dx
Using integration by substitution and integration by parts, we can evaluate the integral on the right-hand side and simplify the equation:
e^(x^2/2)Y = e^(x^2/2) + C - e^(x^2/2)y + D
where C and D are constants of integration.
We Solve for Y:
Y = 1 - y + Ce^(-x^2/2) + De^(x^2/2)
Therefore, the solution of the given differential equation is:
Y = 1 - y + Ce^(-x^2/2) + De^(x^2/2)
where C and D are constants of integration.

limit comparison test
The formal statement of the Limit Comparison Test are discuss below with ∑bₙ converges, then ∑aₙ converges as well.
Define the Limit Comparison?The Limit Comparison Test is a method used to determine the convergence or divergence of a series.
Suppose we have two series, aₙ and bₙ. If we can find a third series, cₙ, such that the limit of the ratio aₙ/cₙ and bₙ/cₙ both exist and are finite, and the limit of aₙ/cₙ divided by bₙ/cₙ is also finite and non-zero, then the two series aₙ and bₙ will converge or diverge together.
In other words, we can say that if the series aₙ diverges, then bₙ also diverges, and if the series bₙ converges, then aₙ also converges.
Here's the formal statement of the Limit Comparison Test:
Let aₙ and bₙ be two positive series. If there exists a positive series cₙ such that [tex]\lim_{n \to \infty} \frac{a_n}{c_n}[/tex] and [tex]\lim_{n \to \infty} \frac{b_n}{c_n}[/tex] both exist and are finite and positive, then:
(i) If ∑bₙ converges, then ∑aₙ converges as well.
(ii) If ∑aₙ diverges, then ∑bₙ diverges as well.

Therefore, the smaller of the two acute angles is 8°.
How to solve trigonometry?Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. Here are some general steps to solve trigonometry problems:
Understand the problem: Read the problem carefully and identify what is being asked for.
Draw a diagram: Draw a diagram of the triangle and label the sides and angles.
Identify the known values: Identify what is given in the problem, such as the lengths of the sides or the measure of an angle.
Choose the appropriate formula: Choose the formula that relates the known values to the unknown value that you need to find.
Solve for the unknown value: Use algebraic manipulation and/or your calculator to solve for the unknown value.
Check your answer: Check your answer to make sure it makes sense and that it satisfies any given constraints.
Let's start by using the trigonometric identity cos(x) = sin(90° - x) for the left-hand side of the equation:
[tex]cos(4x) =[/tex][tex]sin(90^{0} - 4x)[/tex]
Now we can substitute this into the original equation and simplify:
[tex]sin(90^{0} - 4x) = sin(6x + 10)[/tex]
Using the identity sin(a) = sin(b) implies a = b + 2kπ or a = π - b + 2kπ for some integer k, we can set the angles inside the sine function equal to each other and solve for x:
90° - 4x = 6x + 10 + 2nπ or 90° - 4x = π - (6x + 10) + 2nπ
where n is an integer.
Solving for x in the first equation, we get:
10x = 80° + 2nπ
x = 8° + (2n/10)π
Solving for x in the second equation, we get:
10x = 80° + π + 2nπ
x = (8° + π/10) + (2n/10)π
Since we want the acute angle of the right triangle, which is less than 90°, we only need to consider the values of x that satisfy 0° < x < 22.5°. From the two equations above, we see that x can take on values between 8° and 9° or between 89° and 90°. Therefore, the smaller of the two acute angles is 8°.

Work out the perimeter of this semicircle. Take a to be 3.142
Perimeter of circle is 25.7cm
Define semicircleA semicircle is a two-dimensional geometric shape that is exactly half of a circle. It is formed by taking a diameter of a circle and cutting it in half, so that one half of the circle's circumference is traced out by the resulting arc. The boundary of a semicircle is composed of a curved line called the semicircular arc, which is connected to the two endpoints of the diameter, forming a closed shape.
The area of a semicircle is equal to half of the area of the corresponding circle, while its perimeter is equal to the sum of the diameter and half the circumference of the corresponding circle.
