What is a vertex?The intersection of two or more curves, lines, or edges is known as a vertex in geometry (plural: vertices or vertexes), which is frequently represented by the letters S, P, Q, or R. As a result of this definition, vertices are intersection of two lines that create an angle as well as the corners of polygons and polyhedra.
The point where two rays start or meet, where two line segments join or meet, where two lines intersect (cross), or any other suitable arrangement of rays, segments, and lines that results in two straight "sides" coming together at one location is the vertex of an angle.

Which of the following is
equivalent to the complex number
I27?
The equivalent to the complex number i²⁷ is -i.
what is complex numbers?Every complex number may be represented in the form a + bi, where a and b are real numbers. A complex number is an element of a number system that extends the real numbers with a specific element labeled I sometimes known as the imaginary unit, and satisfying the equation
i² = 1.
Given that,
i²⁷ is a complex number
i²⁷ = i²⁴⁺³
i²⁷ = i²⁴ ₓ i³
i²⁷ = i⁴⁽⁶⁾ ₓ i²⁺¹
i²⁷ = (i⁴)⁶ . i².i
Here, we know that i² = -1
so, i⁴ = (i²)²
i⁴ = 1
Hence, 1⁶(-1)(i) = -i
Therefore, the equivalent to the complex number i²⁷ is -i.

two members of the math competition team solve 13 problems in 1 hour. If all team members solve problems at the same rate how many tema members are needed to solve 39 problems in 1 hour
In a case whereby two members of the math competition team solve at the rate 13 problems in 1 hour, the members that are needed to solve 39 problems in 1 hour is 6 member of the team.
How can the rate be calculated?Since two members solve 13 problems in 1 hour, which implies that
2 members= 13 problem/ hr
Then if we want to calculate the number of the team that will be able to solve the problem at the rate of 39 problems in 1 hour, we can represent the number required as X.
Then X = 39 problems/hr.
2 members= 13 problem/ hr
Then in this case we can cross multiply as follows:
13 problem/ hr * X = 39 problems/hr * 2
Then we can make X the subject of the formular as X =( 78 /13)
= 6 member of the team.

What is the area of trapezoid ABCD? Enter your answer as a decimal or whole number in the box. Do not round at any steps.
The area of the trapezoid is given as 100. See the explanation for the same below.
What is a Trapezoid?A trapezoid is a quadrilateral with at least one set of parallel sides in American and Canadian English. A trapezoid is known as a trapezium in British and other varieties of English.
To find the length of each side of the trapezoid, you need to use the distance formula.
AB = (-1,5) and (3,2)
BC = (3,2) and (0,-2)
CD = (0,-2) and (-13, -11)
AD or DA = (-1,5) and(-13, -11)
Now, just use the distance formula for each line.
The Distance Formula is given as: d=√((x2 – x1)² + (y2 – y1)²).
Distance AB = √((3 – (-1))² + (2 – 5)²).
= √(4)² + (-3)²
= √(16+9)
= √25
AB = 5
lets us repeat this for the other section we will get:
Doing so gives us for all the points:
AB = 5
BC = 5
CD = 15.811388300842
DA or AD = 20
Note that:
The height is AD, the first base is AB and the second base is BC. We can plug the values for these sides into the trapezoid area formula, which is:
A = (base 1 + base 2) / 2 x height.
A = (5+5)/2 x 20
A = 5 x 20
A = 100.

It is True to state that Arcs AB, BC, CD, DE, EF, FA in the circumscribed hexagon are all equal. See the explanation below.
What is a regular hexagon?In geometry, a hexagon is a six-sided polygon. A regular hexagon is one in which the lengths of all the sides and the measurements of all the angles are identical. The sides of a regular hexagon are therefore equivalent.
Allow point P to be the hexagon's and circle's center.
The dimension of arc AB is the same as the measure of central angle APB, which are both 360/6 = 60 degrees. This also applies to the other arc measurements. The whole 360-degree circle is divided into six equal parts, each measuring 60 degrees.

Step-by-step explanation:
Question 1Given inequality:
[tex]1+\dfrac{x-5}{2}-\dfrac{x+3}{5} \leq 0[/tex]
[tex]\textsf{Add \; $\dfrac{x+3}{5}$ \; to both sides}:[/tex]
[tex]\implies 1+\dfrac{x-5}{2}-\dfrac{x+3}{5} +\dfrac{x+3}{5}\leq 0+\dfrac{x+3}{5}[/tex]
[tex]\implies 1+\dfrac{x-5}{2}\leq \dfrac{x+3}{5}[/tex]
[tex]\textsf{Rewrite $1$ as $\dfrac{2}{2}$}:[/tex]
[tex]\implies \dfrac{2}{2}+\dfrac{x-5}{2}\leq \dfrac{x+3}{5}[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{c}+\dfrac{b}{c}=\dfrac{a+b}{c}:[/tex]
[tex]\implies \dfrac{2+x-5}{2}\leq \dfrac{x+3}{5}[/tex]
[tex]\implies \dfrac{x-3}{2}\leq \dfrac{x+3}{5}[/tex]
Cross multiply:
[tex]\implies 5(x-3)\leq 2(x+3)[/tex]
[tex]\implies 5x-15\leq 2x+6[/tex]
Subtract 2x from both sides:
[tex]\implies 5x-15-2x\leq 2x+6-2x[/tex]
[tex]\implies 3x-15\leq 6[/tex]
Add 15 to both sides:
[tex]\implies 3x-15+15\leq 6+15[/tex]
[tex]\implies 3x\leq 21[/tex]
Divide both sides by 3:

[tex]\implies \dfrac{6x}{5}-\dfrac{2}{3} +\dfrac{2}{3}\geq 4+\dfrac{2}{3}[/tex]
[tex]\implies \dfrac{6x}{5}\geq \dfrac{12}{3}+\dfrac{2}{3}[/tex]
[tex]\implies \dfrac{6x}{5}\geq \dfrac{12+2}{3}[/tex]
[tex]\implies \dfrac{6x}{5}\geq \dfrac{14}{3}[/tex]
Cross multiply:
[tex]\implies 3(6x) \geq 14(5)[/tex]
[tex]\implies 18x \geq 70[/tex]
Divide both sides by 18:
[tex]\implies \dfrac{18x}{18} \geq \dfrac{70}{18}[/tex]
[tex]\implies x \geq \dfrac{70}{18}[/tex]
Reduce the fraction by dividing the numerator and the denominator by 2:
[tex]\implies x \geq \dfrac{70 \div 2}{18 \div 2}[/tex]
[tex]\implies x \geq \dfrac{35}{9}[/tex]
---------------------------------------------------------------------------------------
Question 3Given inequality:
[tex]\dfrac{x}{10}-\dfrac{2}{8} \geq 1[/tex]
[tex]\textsf{Add \; $\dfrac{2}{8}$ \; to both sides}:[/tex]
[tex]\implies \dfrac{x}{10}-\dfrac{2}{8} +\dfrac{2}{8}\geq 1+\dfrac{2}{8}[/tex]
[tex]\implies \dfrac{x}{10}\geq \dfrac{8}{8}+\dfrac{2}{8}[/tex]
[tex]\implies \dfrac{x}{10}\geq \dfrac{8+2}{8}[/tex]
[tex]\implies \dfrac{x}{10}\geq \dfrac{10}{8}[/tex]
Cross multiply:
[tex]\implies 8(x) \geq 10(10)[/tex]
[tex]\implies 8x \geq 100[/tex]
Divide both sides by 8:
[tex]\implies \dfrac{8x}{8} \geq \dfrac{100}{8}[/tex]
[tex]\implies x \geq \dfrac{100}{8}[/tex]
Reduce the fraction by dividing the numerator and the denominator by 4:

[tex]\implies x \geq \dfrac{25}{2}[/tex]

⇒x =100/ 8
⇒ x= 12.5
Percentage of winning the game by team = 3x
= 3(12.5)
= 37.5%
= 37 1/2%

A reflection is referred to as a twist in geometry. A reflection is the mirror image of shape . A line, called the line of reflection, will agree an image to reflect without change it. When all of the points in a figure are evenly spaced apart from one another, the two figures are said to reflect each other. The reflected picture should have the same size and shape as the original, but it faces the opposite way. Changes in position during contemplation may also result in translation. Pre-image and image are terms used to refer to the same thing in this context. ABC and A'B'C are used to represent the pre-image and image, respectively.
