Answer:

A total of 15 matches were played.

Step-by-step explanation:

To determine the number of matches that were played in the chess tournament, knowing that there are 16 participants who face each other in a tournament of direct elimination, the following logical reasoning must be carried out:

In the first round there are 16 players, so being matches between 2 players, there are 8 matches (16/2). In the second round, applying the same reasoning and taking into account that there are only 8 players left, since the others have been eliminated, there are 4 matches (8/2). The same in the semifinals, where there are 2 games (4/2), and finally, the final to a single game.

Therefore, since 8 + 4 + 2 + 1 equals 15, the number of matches played in the tournament is 15.

Answer:

116 degrees

Step-by-step explanation:

180 - (26 + 90)

180 - 116 = 64 degrees

180 - 64 degrees = 116 degrees

Angle 1 = 116 degrees

Hope that helps!

Answer:

<1 = 116

Step-by-step explanation:

90 + 26 + x = 180

116 + x = 180

x = 64

<1 + 64 = 180

<1 = 116

In mathematics, an equation is an expression that states that two expressions are equal by joining them with the equal sign =.[2][3]. Equations and their cousins ​​in other languages ​​may have subtly different meanings. For example, in French, an equation is defined as containing one or more variables, whereas in English any well-formed expression consisting of two expressions joined by an equal sign is an equation.

To solve an equation involving variables, it is necessary to determine which values ​​of the variables make the equation true. The variables for which the equation must be solved are also called unknowns, and the values ​​of the unknowns that satisfy the equation are called the solution of the equation. There are two types of equations: identities and constraints. The ID applies to all values ​​of the variable. Constraint equations apply only to specific values ​​of variables.

The sum of the arithmetic series is:

893

What are arithmetic progressions?

An arithmetic sequence with a specific number of terms is the sum of all the terms in an arithmetic series.

An arithmetic sequence's first n terms are added together to form (n/2).(a1+an). The arithmetic series formula is what it is known as.

Solution:

Given:

a1 = 11, a2 = 15 and an=83

Step-1:

d= a2 ₋ a1

d= 4

Now, an = a ₊ (n ₋ 1)d

          83 = a ₊ (n ₋ 1)4

          83 = 11 ₊ 4n ₋4

          83 = 7 ₊ 4n

         4n = 83 ₋ 7

          n = 19

Step-2:

Now, Sn = n/2 (a1 ₊ an)

         Sn = 19/2 (11 ₊ 83)

         Sn = 19/2 ₓ 94

         Sn = 893

Hence we get the answer as 893

Answer:

length = 1273.2 cm or 12.73 m

Step-by-step explanation:

Assume no loss.

diameter of wire, d = 2 mm

radius of wire, r = 1 mm = 0.1 cm

Volume of block, V = 5*4*2 = 40 cm^3

cross sectional area of wire, A = pi (r^2) = pi 0.1^2 = 0.01pi cm^2

Length of wire

= V/A  

= 40 cm^3 / 0.01pi cm^2

= 4000/pi cm

= 1273.2 cm

= 12.73 m

Plot the coordinates on the graph. The distance between the two points is horizontal distance = 7.

A graph is a representation of the relationship between two variables that are normally measured along one of a pair of axes at right angles. A graph is a structure that amounts to a set of items where certain pairs of the objects are in some manner "connected" in discrete mathematics, more especially in graph theory. The items are represented by mathematical abstractions known as vertices (sometimes known as nodes or points), and each pair of connected vertices is known as an edge (also called link or line)

The given points are  (−7,−10) and ( 7 , − 10 ).

Answer:

x is an independent variable

Step-by-step explanation:

X is independent

Y is dependent

Answer:

C) y = 2x + 3

Step-by-step explanation:

In slope intercept form(y = mx + b), b is the y intercept and m is the slope. The y intercept is y variable when the x variable is 0. In the chart, the y-intercept(b) is 3. Slope is identified by the different in y by the difference in x. In this chart the slope is 2. Now plug in the number into slope intercept form( y = 2x + 3).

The formula for the velocity, v is √2E/m

Kinetic energy is half the mass multiplied by the square of the speed of the object

It is written thus;

Kinetic energy = 1/ 2 × m × v²

To solve for 'v' mean that we should make 'v' the subject of formula

E = 1/ 2 mv²

E = \(\frac{mv^2}{2}\)

cross multiply

\(2E = mv^2\)

To make 'v' the subject, we have

\(v = \sqrt{\frac{2E}{m} }\)

Thus, the formula for the velocity, v is √2E/m

Answer:

The difference throughout the means isn't significant because a difference of 2.5 isn't very likely. A further explanation is provided below.

Step-by-step explanation:

Given:

The mean time of warm up group,

= 13.2

The mean time of non warm up group,

= 10.7

Now,

The mean difference will be:

= \(The \ mean \ time \ of \ warm \ up \ group - The \ mean \ time \ of \ non \ warm \ up \ group\)

By substituting the values, we get

= \(13.2-10.7\)

= \(2.5\)

Thus the above is the appropriate response.

Answer:

C.  The difference in the means is significant because a difference of 2.5 is not very likely.

Answer:

70 degrees = a

Step-by-step explanation:

Triangle= 180 degrees.

Therefore, since a and the unmarked angle are congruent since it is an isosceles triangle, we subtract 40 from 180, with a result of 140. With 140, we divide by 2 to find the degrees for both the unmarked angle and angle a, since they are congruent. 140/2 = 70, Angle A will equal to 70 degrees

Answer:

a = 2, b = 0 , x = \(\frac{1}{2}\)

Step-by-step explanation:

Given that x = 0 and x = 2 are zeros of p(x) , then

p(0) = 0 and p(2) = 0

p(0) = 2(0)³ - 5(0)² + a(0) + b = 0 , that is

0 - 0+ 0 + b = 0, then b = 0

p(2) = 2(2)³ - 5(2)² + 2a + b = 0 , that is

16 - 20 + 2a + 0 = 0

- 4 + 2a = 0 ( add 4 to both sides )

2a = 4 ( divide both sides by 2 )

a = 2

Then

p(x) = 2x³ - 5x² + 2x ← factor out x from each term

      = x(2x² - 5x + 2)

      = x(2x - 1)(x - 2)

To find zeros equate p(x) to zero

x(2x - 1)(x - 2) = 0

Equate each factor to zero and solve for x

x = 0

x - 2 = 0 ⇒ x = 2

These are the 2 zeros already known (given)

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = \(\frac{1}{2}\) ← third zero of p(x)

The "switch" statement is useful when you need to test a single variable against a series of exact integer, character, or string values.

The switch statement is a control structure found in many programming languages, including C++, Java, and JavaScript. It allows you to evaluate a variable or expression and compare it against multiple cases.

Each case represents a specific value that the variable or expression is tested against. When a match is found, the corresponding block of code associated with that case is executed.

The switch statement is particularly useful when you have a variable that can take on different values and you want to perform different actions based on those values. Instead of writing multiple if-else statements, the switch statement provides a more concise and efficient way to handle such scenarios.

Answer:

Real numbers are not closed under cube root

Step-by-step explanation:

The cube of each real number is increasing as the real numbers increases, giving a functional or one to one relationship. Therefore, the cube roots of real number have also a one to one relationship.

Given that a cube root of a number, ∛x = y therefore, y³ = x, we have that all real numbers, excluding zero, have one cube root, and two complex and conjugate roots

For the real number, 8, we have the cube roots given as follows;

∛8 = 2

Also, ∛8 = -1 + √3i and -1 - √3i

Given that not all cube roots of 8 are real numbers we have that real numbers are not closed under cube root.
