Answer:         A tiling of regular polygons (in two dimensions), polyhedra (three dimensions), or polytopes ( dimensions) is called a tessellation. Tessellations can be specified using a Schläfli symbol. The breaking up of self-intersecting polygons into simple polygons is also called tessellation.

I know the best answer ever (*says sarcastically*)

The function's minimum value is -1, and as x moves away from the vertex in either direction, it gets smaller.

If a polynomial function has one or more variables and a variable with a maximum exponent of two, it is said to be quadratic. It is frequently referred to as the polynomial of degree 2 since the second-degree term in a quadratic function has the highest degree.

The graph displays a quadratic function with a downward opening (a negative leading coefficient). The minimal point of the function, point (2,-1), is where the parabola's vertex is located. The graph's x-intercepts, which are the solutions to the equation f(x) = 0, are (0,4) and (4,0).

The vertical line that passes through the vertex and has the value x = 2 is the parabola's axis of symmetry. As there are no limitations on the input values of x, the function's domain spans the entire real number range. As the function's minimum value is -1, its range is all real values less than or equal to -1. The function decrements as x moves away from the vertex in either direction.

An adult has a total of about 22.9 square feet of skin . if we use fact that 1 meter is approximately equal to 3.281 feet . Thus  22.9 square feet should be equal to 2.12 meter².

Here, we know that

1 m = 3.281 ft

1 m² = (3.281 ft)²    (∵ squaring both the side of equation )

now we are going to convert 22.9 ft² to m²

1 m²= ( 3.281 ft )²

22.9 m² = x ft²

x ft² = 22.9 m²/ (3.281 ft )²

x ft² = 22.9 m²/ 10.7649 ft²

x ft² =  2.12 m²

So, 22.9 square feet is equal to 2.12  meter².

Answer: 0.9554

Step-by-step explanation:

Let \(\overline{X}\) be the sample mean.

Given: Mean weight\((\mu)\) of an adult is 65 kilograms with a standard deviation\((\sigma)\) of 13 kilograms.

Sample space = 92

The probability that the sample mean would be greater than 62.7 kilograms:

\(P(\overline{X}>62.7)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{62.7-65}{\dfrac{13}{\sqrt{92}}})\\\\=P(Z>-1.70)\\\\=P(Z<1.70)\ \ \ \[P(Z>-z)=P(Z<z)]\\\\=0.9554\)[ By p-value table]

Hence, the required probability= 0.9554

The length of AB would be = 10 units and the midpoint of segment AB would be (-5, 2).

What are the distance formula and midpoint of a segment?

The distance formula is a mathematical formula that can be used to determine the distance between two points in a coordinate plane. The distance between two points (x1, y1) and (x2, y2) is given by the formula:

\(d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}\)

The midpoint of a segment is a point that is exactly in the middle of a line segment. Given the endpoints of the line segment, (x1, y1) and (x2, y2) the coordinates of the midpoint, (x, y) can be calculated using the following formulas:

x = (x1 + x2) / 2

y = (y1 + y2) / 2

The given points are (-8, 6) and (-2, -2).

Given two points A(x1, y1) = (-8, 6) and B(x2, y2) = (-2, -2), we can use the distance formula to find the length of the line segment AB. The distance formula is:

\(d = \sqrt{(x2 - x1)^2 + (y2 - y1)^2}\\\\d= \sqrt{((-2) - (-8))^2 + ((-2) - (6))^2}\\\\d=\sqrt{36 + 64}\\\\d=\sqrt{100}\\\\d=10\)

The length of AB would be 10.

To find the coordinates of the midpoint of AB, we can use the midpoint formula:

x = (x1 + x2) / 2

y = (y1 + y2) / 2

Plugging in the values for A and B, we get:

x = (-8 + (-2)) / 2 = -5

y = (6 + (-2)) / 2 = 2

The coordinates of the midpoint of AB are (-5, 2).

Hence, the length of AB would be = 10 units and the midpoint of segment AB would be (-5, 2).

We want to find the factors of:

To do that we simply have to factorise the equation.

That is we need two numbers such that:

their sum = 20

their product = 4 * 25 = 100

The two numbers we need are 10 and 10.

That is:

That is the answer.

To find the area of the arena, you will need to find the areas of the rectangular spaces and the 2 semicircles. Because the formulas are given, I will just substitute in the values and show the work for finding the areas.

To find the perimeter, you will look at the distances of lines that take you around the space. Because two of these spaces are half circles, you will need to find the circumference of the full circle.

Also, the answers need to be given in meters, so all units given in centimeters will be divided by 100 to convert them to meters.

Perimeter:

C= 3.14 x 20 m

C = 62.8 meters

62.8 + 8 + 25 + 8 + 5 + 8 + 10 + 8 + 40= 174.8 meters for the Perimeter

Area:

A = 25 x 8

A = 200 square meters

A = 10 x 8

A = 80 square meters

A = 20 x 40

A = 800 square meters

A = 3.14 x 10^2

A = 314 square meters

Total Area: 314 + 800 + 80 + 200= 1394 square meters

The angle between the sides measuring 4 and 5 in the obtuse triangle is approximately 101.54 degrees.

To find the measure of the angle between the sides measuring 4 and 5 in an obtuse triangle with side lengths 4, 5, and 7, we can use the Law of Cosines. The Law of Cosines states that in a triangle with side lengths a, b, and c, and an angle opposite to side c, the following equation holds:

\(c^2 = a^2 + b^2 - 2ab*cos(C)\)

In this case, we have side lengths a = 4, b = 5, and c = 7. We want to find the angle C, which is opposite to side c. Substituting these values into the Law of Cosines, we get:

\(7^2 = 4^2 + 5^2\)- 2(4)(5)*cos(C)

49 = 16 + 25 - 40*cos(C)

49 = 41 - 40*cos(C)

40*cos(C) = 41 - 49

40*cos(C) = -8

cos(C) = -8/40

cos(C) = -0.2

To find the measure of angle C, we can take the inverse cosine (arccos) of -0.2:

C = arccos(-0.2)

Using a calculator, we find that C ≈ 101.54 degrees.

Therefore, the measure of the angle between the sides measuring 4 and 5 in the obtuse triangle is approximately 101.54 degrees.

y = f/9

Step-by-step explanation:

Area of a floor in square yards = y = f/9

Area of a floor in square feet = f

The number that represents the area of the floor in square feet is 9 times the number representing the area in square yards. This makes sense because the ratio of yard to feet is 1 : 3 and the ratio of square yard to square feet is the same ratio but squared so 1 : 9.

If y represents the area in square yards and f the area in square feet.
