Answer: 1.5

Step-by-step explanation:

The width W of the island will be 3.75 ft by given scaling factor.

What exactly is scaling factor?

The Scale Factor is used to scale shapes in various dimensions. Geometry teaches us about various geometrical shapes in both two and three dimensions. The scale factor is a statistic for figures that seem similar but have different scales or measures. Imagine two circles have the same appearance but different radii.

The scale factor specifies how much larger or smaller a figure is than the original figure. With the use of a scale factor, you may design an expanded or smaller version of any original form.

Now,

Here given that 1 inch=1.5 ft

and as w=2.5 inches then the actual width W will be =2.5*1.5

=3.75 ft

and we can find scaling factor by  length of the actual object divided by length of scale drawing i.e.

S=length of object/length of drawing

hence,

          The width W of the island will be 3.75 ft.

Therefore, the lateral surface area of the cube is 35/2 square inches.

In mathematics, area is the measure of the size of a two-dimensional region or surface. It is usually measured in square units, such as square meters, square feet, or square centimeters. The area of a shape or surface is determined by the amount of space it covers in a plane or on a flat surface. Areas are commonly used to describe the size of objects or spaces in a variety of contexts, including geometry, architecture, engineering, and physics. They are also used in everyday life, such as calculating the amount of carpet needed to cover a floor or the amount of paint needed to cover a wall.

Here,

Since the package is a cube, all of its faces are identical squares. Therefore, the area of one face is equal to the length of one side squared.

Let x be the length of one side of the cube. Then we have:

x² = 7(5)/8

Solving for x, we get:

x = √(7(5)/8) = sqrt(35/8)

The lateral surface area of the cube is the sum of the areas of the four non-base faces. Since the cube has six faces in total, the lateral surface area is:

Lateral surface area = 4 * (side length)²

Lateral surface area = 4 * x²

Lateral surface area = 4 * (√(35/8))²

Lateral surface area = 4 * 35/8

Lateral surface area = 35/2

The illustration of 10 sided polygon is attached below.

Polygons are closed geometric figures made up of line segments that are connected end-to-end. The number of sides of a polygon determines the polygon's name.

In mathematical terms, a decagon is a 10-sided polygon with 10 vertices and 10 angles.

To draw a decagon, we need to start by drawing a circle. We can use a compass to draw a circle of any size we want. The radius of the circle will determine the size of the decagon.

Next, we need to draw a horizontal line through the center of the circle. This line will be the base of the decagon, and it will divide the circle into two equal halves.

Since a decagon has 10 sides, we need to divide the circle into 10 equal parts.

We can then use these lines as guides to draw the sides of the decagon. We start at one of the points where the lines intersect the circle, and draw a line segment to the next point.

We can label the vertices of the decagon with numbers, starting with 1 and going clockwise, as shown in the diagram.

Answer:

x = 28

Step-by-step explanation:

Since the e interior angles formed by the sides of a quadrilateral have measures that sum to 360°

we get 2x° + 2x° + 124° + 124° = 360°

4x° + 248° = 360°

4x° = 360° - 248 °

4x° = 112°

x = 112/4 = 28

What is the Law of Sines?

The Law of Sines, also known as the sine rule, is a trigonometric formula used to find unknown sides or angles in a triangle.

To solve this problem, we can use the Law of Sines, which states that for any triangle ABC,

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, and c are the side lengths opposite the corresponding angles A, B, and C, respectively.

Using this formula, we can set up the following proportion:

b/sin(B) = a/sin(A)

Plugging in the values we know, we get:

b/sin(36°) = 6/sin(121°)

Solving for b, we get:

b = (6 sin(36°))/sin(121°)

Using a calculator, we find that b ≈ 3.9 inches (rounded to the nearest 10th of an inch).

Any system of geometry that is not based on the principles of Euclidean geometry is known as non-Euclidean geometry.

Many geometrical systems that are not based on the parallel postulate or other Euclidean axioms are referred to as non-Euclidean geometry.

The parallel postulate asserts that given a line and a point off the line, there is only one line that can be drawn through the point parallel to the provided line.

Attempts to establish or refute this postulate gave rise to non-Euclidean geometries. Contrarily, non-Euclidean geometries are founded on diverse axioms that allow for various kinds of parallel lines, including multiple parallel lines in hyperbolic geometry and no parallel lines in elliptic geometry.

Non-Euclidean geometry is important to many fields of mathematics and science, including relativity theory and cosmology.

An inequality in mathematics depicts the connection between two values in an algebraic statement that are not equal. One of the two variables on the two sides of the inequality may be greater than, greater than or equal to, less than, or less than or equal to another value, according to inequality signals.

Consider

x-2y ≤ -2

Find y

=> x +2  ≤  2y

=> x/2 + 1 ≤ y

=> (x+2)/2  ≤ y

Or

y ≥(x+2)/2  --------(1)

Find y

=> y > -3x -1---------(2)

By considering the equations with equal sign in place of inequality signs, find y values corresponding to the random x values

Using trigonometric identity, cos(2θ-1) / cos(2θ+1) is equal to [(1 - 2tan^2(θ))cos(1) + 2tan(θ)sin(1)] / [(1 - 2tan^2(θ))cos(1) - 2tan(θ)sin(1)]

We can use the trigonometric identity:

cos(2θ) = 1 - 2sin^2(θ)

to rewrite the expression as follows:

cos(2θ-1) = cos(2θ)cos(1) + sin(2θ)sin(1) = (1 - 2sin^2(θ))cos(1) + 2sin(θ)cos(θ)sin(1)

Similarly,

cos(2θ+1) = cos(2θ)cos(1) - sin(2θ)sin(1) = (1 - 2sin^2(θ))cos(1) -  2sin(θ)cos(θ)sin(1)

Dividing these two expressions, we get:

cos(2θ-1) / cos(2θ+1) = [(1 - 2sin^2(θ))cos(1) + 2sin(θ)cos(θ)sin(1)] / [(1 - 2sin^2(θ))cos(1) - 2sin(θ)cos(θ)sin(1)]

Now, we can use the identity:

tan(θ) = sin(θ) / cos(θ)

to simplify the expression. Specifically, we can express sin(θ) in terms of tan(θ) and cos(θ) as follows:

sin(θ) = tan(θ)cos(θ)

Substituting this into the expression for cos(2θ-1) / cos(2θ+1), we get:

cos(2θ-1) / cos(2θ+1) = [(1 - 2tan^2(θ))cos(1) + 2tan(θ)sin(1)] / [(1 - 2tan^2(θ))cos(1) - 2tan(θ)sin(1)]

Step-by-step explanation:

the inscribed angle ADB is half the arc that subtends it , AB , then

BC = 22°

Then

ABC = AB + BC = 92° + 22° = 114°

BD is a diameter of the circle , so BAD = 180° THEN

AD = 180° - AB = 180° - 92° = 88°

The nth derivative of each function is n!.

Taking the nth derivative of a function is the process of calculating successive derivatives and observing the patterns that occur.

In your example, the function given is f(x) = xⁿ. To find the nth derivative, you need to calculate the first few derivatives and observe the pattern that occurs.

The first derivative of the function f(x) = xⁿ is f'(x) = [tex]nx^{n-1}[/tex]

The second derivative is f''(x) = [tex]n(n-1)x^{n-2}[/tex]

From here, you can see that the pattern is that the exponent of x decreases by 1 each time, and the coefficient of x increases by n-1 each time.

Therefore, the nth derivative of

f(x) = xⁿ => f^(n)(x) = [tex]n(n-1)(n-2)...(n-(n-1))x^{n-n}[/tex] = n!x⁰ = n!.

This result is true for any value of n, so the nth derivative of f(x) = xⁿ is always equal to n.
