Find the circumference and area of a circle with diameter 16 ft. Express your answer in terms of π.

Answer:

Angle 2: Acute, supplementary

Angle 5: Obtuse, congruent

Step-by-step explanation:

An acute angle is less than 90 degrees. An obtuse angle is more than 90 degrees. A supplementary angle is an angle equal to 180 degrees when added to another angle. (Angle 1 + angle 2 = 180 degrees.) Congruent angles are equal to each other in degrees. (Angle 5 = angle 8.)

Answer:

x=12

Step-by-step explanation:

Our equation: 3x + 4= 40

40-4=36. 36/3 = 12

As A and B are vertical angles, the measures of angle A and B is 98° each.

When two lines collide, vertical angles are created. The angles that are directly opposite one another, out of the four that are generated, are vertical angles. Additionally, they are known as "vertically opposed angles." All of these angles are equal.

Vertical angles are created when two straight lines cross. Angles vertically are consistently congruent and equal. As the two sets of non-adjacent angles created by crossing two lines superimpose on one another, vertical angles are congruent.

As A and B are vertical angles,

6x - 16 = 4x + 22

⇒ 2x = 38

⇒ x = 19

Measure of Angle A is 98°

Measure of Angle B is 98°

Using given algebraic equation, Keelan collected 431 tokens.

In mathematics, an expression that incorporates variables, constants, and algebraic operations is known as an algebraic expression (addition, subtraction, etc.). Terms comprise expressions.

At least one variable and one operation must be present in an algebraic expression (addition, subtraction, multiplication, division). One such algebraic statement is 2(x + 8y).

You must substitute a number for each variable and carry out the arithmetic operations in order to evaluate an algebraic statement. Since 6 + 6 equals 12, the variable x in the example above is equal to 6. If we are aware of the values of our variables, we may substitute those values for the original variables before evaluating the expression.

Given,

p=20x+75

p = 8695

8695 = 20x + 75

x = 8695 - 75 / 20

x = 431

Using the uniform distribution, we have that:

a) The graph is given at the end of the answer.

b) Jayden waits more than 7 minutes 30% of the days.

c) The 38th percentile is of 3.8 minutes.

It is a distribution with two bounds, a and b, in which each outcome is equally as likely.

The probability of finding a value of at lower than x is:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

The probability of finding a value between c and d is:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

The probability of finding a value above x is:

[tex]P(X > x) = \frac{b - x}{b - a}[/tex]

For this problem, the bounds are given as follows:

a = 0, b = 10.

As shown in the graph at the end of the answer.

The probability of waiting more than 7 minutes is:

[tex]P(X > 7) = \frac{10 - 7}{10 - 0} = 0.7[/tex]

Jayden waits more than 7 minutes 30% of the days.

The 38th percentile is x for which P(X < x) = 0.38, hence:

[tex]P(X < x) = \frac{x - a}{b - a}[/tex]

0.38 = x/10

x = 3.8.

The 38th percentile is of 3.8 minutes.

Since in the image above angle 3 is 79 degrees, angle 11 is also equal to 79 degrees based on the vertical angles theorem.

Parallel lines can be defined as two (2) lines that are always the same (equal) distance apart and never meet.

The vertical angles theorem is also referred to as vertically opposite angles theorem and it states that two (2) opposite vertical angles that are generally formed whenever two (2) lines intersect each other are always congruent, which simply means being equal to each other.

In Geometry, when two (2) parallel lines are cut by a transversal, the interior angles that are formed on the same side of the transversal are supplementary angles, which makes:

Angle 3 = Angle 14

Angle 14 = Angle 9

Angle 3 ≅ Angle 9 (Congruent angles or supplements of the same angle)

By applying the vertical angles theorem, we have:

Angle 9 ≅ Angle 11 = 79 degrees.

The point of discontinuity for y= x²-x-2 / 3 x²-7 x+2 is x= 1/3 and x= 2.

What is discontinuous function?

Mathematics, functions, and applications all place a premium on continuous functions. But not every function is continuous. A function is said to have a discontinuity there if it is not continuous at that point in its domain.

Given,

y = x²-x-2 / 3 x²-7 x+2

It can be expressed in the form of -

⇒ y = (x-2) (x+1) / (3x-1) (x-2)

The function will be undefined if the denominator will be 0

⇒ 3x-1 = 0

⇒ x = 1/3

⇒ x-2 = 0

⇒x = 2
