On solving the provided question, we can say that the perimeter can be calculated by add all lengths of the figure =  5.6 + 8+5.6+4.5+3.5 = 27.2units

A limit is a closed route that surrounds, delimits, or includes a two-dimensional form or a one-dimension length. The outermost part of a circle or an ellipse is called the perimeter. The perimeter calculation has several real-world applications. A shape's perimeter is the measurement of its edge's radius. Discover how to determine the circle by adding together the lengths of both the sides of irregular configurations. The perimeter of any form may be calculated by multiplying its side lengths. An object's perimeter is the region that surrounds it. A good illustration of this at your house is a closed-off garden. Its perimeter is the space around something. For a 50 by 50 foot yard, a 200 foot barrier will be required.

For the given trapezoid,

a) Length of AB is found by

   b² = 3² + 4²

b) Perimeter = 30 units.

What is a trapezoid?

A trapezoid is a quadrilateral with at least one pair of parallel sides. A polygon with only one set of parallel sides is called a trapezoid. The parallel bases of a trapezoid are another name for these parallel sides. Trapezoids have two additional sides that are not parallel and are referred to as their legs. A trapezoid is a closed, four-sided form or figure that has a perimeter and covers a specific area. It is a 2D figure rather than a 3D one.

The trapezoid is given in the figure below.

a) In this trapezoid, we can draw a perpendicular from B to the line AD. Let this point be E.

So the triangle ABE will be a right triangle.

Now the hypotensue will be AB.

Using Pythagoras' theorem, we can write the following relation.

AB² = AE² + BE²

From the graph of the trapezoid, we can get

AE= 4 -1 = 3 units

BE = 7 - 3 = 4 units

So if AB =b

The length of AB can be found using the,

b² = 3² + 4²

b = 5

Therefore the given statement is false.

b) The perimeter of trapezoid  = perimeter of triangle ABE + periemeter of rectangle BCDE

                                      = 5+4+3 +  2* (5+4)

                                      = 12 + 18 = 30 units.

Therefore for the given trapezoid, the perimeter is 30 units.

113.09724, is the diameter of craig's balloon.

What is volume ?

The area or capacity of a cone is determined by its volume.

A cone's circular base tapers from a flat base to a point known as the apex or vertex in three dimensions.

A cone is made up of a collection of line segments, half-lines, or lines that connect the apex—the common point—to each point on the base, which is in a plane without the apex.

A cone can be thought of as a collection of irregularly shaped circular disks placed on top of one another with the ratio of their radii remaining constant.

A three-dimensional shape's volume is determined by how much space it takes up.

According to our question-

V = 4/3 * * r3 is the formula for a sphere's volume.

Your balloon's diameter is 6,

hence its radius is 3.

V = 4/3 * 3.14159 * 33 = 113.09724

Hence, 113.09724, is the diameter of craig's balloon.

To find the value table of a linear function take, any values for 'x' and from that find the 'y' values for each corresponding value of 'x'.

Here in this problem, we are taking x values as 0, 1, 2, and 3. Now substitute each of the 'x' values and find the 'y' values and make the table of values.

Here we have  

The linear function given is y = 4x + 1

To find the value table we are taking x values as - 1, 0, 1, 2, 3  

At x = - 1 => y = 4(-1)  + 1

=> y = - 4 + 1

=> y = - 3

At x = 0 => y = 4(0) + 1

=> y = 0 + 1

=> y = 1

At x = 1 => y = 4(1) + 1

=> y = 4 + 1

=> y = 5

At x = 2 => y = 4(2) + 1

=> y = 8 + 1

=> y = 9

At x = 3 => y = 4(3) + 1

=> y = 12 + 1

=> y = 13

An 8-sided polygon is called an octagon. The word "octagon" comes from the Greek words "okto," which means "eight," and "gonia," which means "angle."

An octagon is a two-dimensional shape that has eight straight sides and eight angles. All of the angles in an octagon add up to 1080 degrees, and each of the eight angles in a regular octagon (an octagon with equal side lengths and equal angles) measures 135 degrees.

Octagons are a common shape in geometry and can be found in a variety of applications, such as in architecture, art, and engineering. For example, many stop signs and traffic signals are octagonal in shape. In architecture, octagons are used in the design of buildings and rooms, and are often used to create interesting visual effects.

Answer:

≈ 106.5 feet

Step-by-step explanation:

Let's start by drawing a picture of the situation. Imagine a kite flying in the air, with a string attached to it that is pulled taut (pulled tight so there's no slack). The string is 86 feet long. We want to know how high the kite is in the air, and we know that the angle of elevation of the kite is 53 degrees.

Now, the angle of elevation is the angle between the horizontal (the ground) and the line of sight from the observer (you) to the object (the kite). In this case, you are looking up at the kite, so the line of sight is the string that connects the kite to the ground.

To find the height of the kite, we need to use trigonometry. Specifically, we'll use the tangent function, which relates the opposite side of a right triangle (in this case, the height of the kite) to the adjacent side (in this case, the length of the string) and the angle of elevation.The formula for the tangent function is:

tan(theta) = opposite/adjacent

Where theta is the angle of elevation, opposite is the height of the kite, and adjacent is the length of the string.

We know that the angle of elevation is 53 degrees, and the length of the string is 86 feet. So we can plug those values into the formula and solve for the height of the kite:

tan(53) = opposite/86

opposite = 86 * tan(53)

         ≈ 106.5

So the height of the kite is approximately 106.5 feet.

The given statement "The total area under the frequency polygon for a continuous random variable equals 1" is true because the total area under the frequency polygon is a measure of the probability of the variable and the probability of a continuous random variable is always equal to 1

Frequency polygons are graphical representations of a continuous random variable. The total area under the frequency polygon for a continuous random variable is a measure of the probability of the variable. In this problem, we are asked if the total area under the frequency polygon for a continuous random variable equals 1.

The answer is true. The total area under the frequency polygon for a continuous random variable indicates the probability of the variable. Since the probability of a continuous random variable is always 1, the total area under the frequency polygon also equals 1.

The given integral is solved by using integration by parts. And the required answer for the integral of x lnx is [tex]\int x\ln (x) \;dx=\frac{1}{2}x^2\ln x-\frac{1}{4}x^2+C[/tex].

Integration by parts is a special method that is used when we have to integrate the product of two functions. This method is also called the product rule for integration. Using this method, we consider the integral of x ln x as the product of two functions such as x and ln x. This is solved by using the formula, [tex]\int u\;dv = uv- \int v\;du[/tex].

Let's take u = ln x, dv = x dx, [tex]v=\frac{1}{2}x^2[/tex], [tex]du =\frac{1}{x}dx[/tex]. Then,

[tex]\begin{aligned}\int u\;dv &= uv- \int v\;du\\\int \ln x \cdot xdx&=\ln x\times \frac{x^2}{2}-\int \frac{x^2}{2}\times\frac{1}{x}dx\\&=\frac{1}{2}x^2\ln x-\frac{1}{2}\int xdx\\&=\frac{1}{2}x^2\ln x-\left[\frac{1}{2}\times\frac{1}{2}x^2\right]+C\\&=\frac{1}{2}x^2\ln x-\frac{1}{4}x^2+C\end{aligned}[/tex]

From the question, we have the following parameters that can be used in our computation:

We start by calculating the side lengths using

Perimeter = 2 * (Length + Width)

So, we have

2 * (Length + Width) = 28

Divide by 2

Length + Width = 14

Because the y-axis is a line of symmetry, then it means that the rectangle is divided into equal segments by the y-axis

Here, we can assume that

Length = Width (this is so because a square is a type of rectangle)

So, we have

Length = Width = 7

The above computations also mean that the vertices are equidistant from the axes and the origin
