Answer: B) 37.68

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle and π (pi) is a mathematical constant approximately equal to 3.14.

Plugging in the given radius of 6 centimeters, we get:

C = 2πr

C = 2π(6)

C ≈ 37.68

Cosine is negative, we know that angle C is obtuse. Therefore, the triangle with sides 9, 15, and 19 is an obtuse triangle.

What is triangle ?

Triangle can be defined in which it consists of three sides, three angles and sum of three angles is always 180 degrees.

To determine whether a triangle with sides 9, 15, and 19 is acute or obtuse, we can use the Law of Cosines, which relates the sides and angles of a triangle:

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

where a, b, and c are the side lengths, and C is the angle opposite side c.

In this case, we have:

a = 9, b = 15, c = 19

Using the Law of Cosines, we can solve for the cosine of angle C:

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

cos(C) = (9^2 + 15^2 - 19^2) / (2915)

cos(C) = -0.283

Since, cosine is negative, we know that angle C is obtuse. Therefore, the triangle with sides 9, 15, and 19 is an obtuse triangle.

By using the method of Normal Distribution, Marques made 4 three point shots and 4 free throws.

Let's denote the number of three point shots that Marques made as x and the number of free throws he made as y.

According to the problem, Marques made a total of 8 shots, so we have:

x + y = 8

And he scored a total of 12 points, which can be expressed as:

3x + y = 12

We now have a system of two equations with two unknowns:

x + y = 8

3x + y = 12

We can solve this system by either substitution or elimination. Here, we'll use the elimination method.

Multiplying the first equation by 3, we get:

3x + 3y = 24

Subtracting the second equation from this, we get:

2y = 12 - 3x

Dividing by 2, we get:

y = 6 - (3/2)x

We can substitute this expression for y into the first equation:

x + (6 - (3/2)x) = 8

Simplifying, we get:

(1/2)x = 2

x = 4

So Marques made 4 three point shots. We can substitute this value into either of the original equations to find y:

4 + y = 8

y = 4

So Marques made 4 free throws.

Using the conversion formula of converting temperatures from Celsius to Fahrenheit, we get 36.6°C is 98.68°F.

Temperature is often measured using two different scales: Celsius (°C) and Fahrenheit (°F). To convert a temperature in Celsius to Fahrenheit, we use the formula °F = (°C × 9/5) + 32. In this formula, we first multiply the temperature in Celsius by 9/5 (which is equivalent to multiplying it by 1.8), and then add 32 to the result.

So for example, to convert 36.6 degrees Celsius to Fahrenheit, we plug in 36.6 for °C, and get:

°F = (36.6 × 9/5) + 32

°F = 98.68

Therefore, 36.6 degrees Celsius is equivalent to 98.68 degrees Fahrenheit. This conversion is useful for comparing temperature measurements between different regions, where different temperature scales are commonly used.

[tex]x!/10^{(6x)}[/tex] diverges as x approaches infinity.

What is expression ?

In mathematics, an expression is a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. Expressions can be as simple as a single number or variable, or they can be complex combinations of multiple variables and operations.

Examples of expressions include:

3 + 5

x - 2y

(a + b) * (c - d)

2x^2 + 3x - 5

sin(x) / cos(x)

Expressions can be evaluated to obtain a numerical value or simplified to make them easier to work with. For example, the expression 2x^2 + 3x - 5 can be simplified by factoring as (2x - 5)(x + 1) or by completing the square as 2(x + 3/4)^2 - 49/8.

Expressions are an important part of algebra and other branches of mathematics, where they are used to represent mathematical relationships and solve equations. They are also used in computer programming and other areas of science and engineering to represent mathematical models and calculations.

According to given condition :

The expression [tex]x!/10^{(6x)}[/tex] is a mathematical function that represents the factorial of x divided by 10 to the power of 6 times x. This expression diverges as x becomes large because the factorial function grows much faster than the exponential function.

As x increases, the value of x! grows very rapidly because x! is the product of all integers from 1 to x. In contrast, the value of 10^(6x) grows much more slowly because it is an exponential function with a fixed base of 10.

Therefore, as x gets larger, the value of [tex]x!/10^{(6x)}[/tex] grows very rapidly, eventually becoming much larger than any fixed value. This means that the expression diverges to infinity as x approaches infinity.

To see this more formally, we can use Stirling's approximation, which states that n! is approximately equal to [tex](n/e)^n * sqrt(2pin)[/tex] for large values of n. Substituting this into the expression for [tex]x!/10^{(6x)}[/tex], we get:

[tex]x!/10^{(6x)} ≈ [(x/e)^x * sqrt(2pix)] / 10^{(6x)}[/tex]

Taking the logarithm of both sides, we get:

[tex]ln(x!/10^{(6x)}) ≈ x * ln(x/e) + 0.5 * ln(2pix) - 6x * ln(10)[/tex]

As x approaches infinity, the first two terms on the right-hand side dominate, and the expression grows without bound.

Therefore, [tex]x!/10^{(6x)}[/tex]diverges as x approaches infinity.

Formula a = (v = 2 * pi * r / t)

Formula b = (v2 = g * m_central / r)

The scenario in context to formula a and formula b is given below:

Formula a = (v = 2 * pi * r / t)

It is used to calculate the velocity (v) of a circular object moving with a constant speed around a circle of radius (r) in time (t).

Example scenario: if you want to find the velocity of a moving object in a circular path, use formula a.

Suppose you want to find the velocity of a car moving in a circular path on a race track. The radius of the track is "r" and the time taken for the car to complete one lap is "t".

Using the equation (v = 2 * pi * r / t), we can calculate the velocity as follows:

Let's say the radius of the track is 100 meters and the time taken for the car to complete one lap is 60 seconds. Then, the velocity can be calculated as follows:

v = 2 * pi * (100 m) / (60 s)

v = 31.42 m/s

So, the velocity of the car moving in a circular path on the race track is 31.42 m/s.

Formula b = (v2 = g * m_central / r)

It is used to calculate the velocity squared (v^2) of an object moving under the influence of a central force (g * m_central) and is related to the radius (r) of its orbit.

Example scenario: If you want to find the velocity squared of an object under the influence of a central force, use formula b.

Suppose you want to find the velocity squared of a planet moving in a circular orbit around a star (a central force). The mass of the star is "m_central" and the distance of the planet from the star is "r".

Using the equation (v²  = g * m_central / r), we can calculate the velocity squared as follows:

v² = (6.67 x 10^-11 N m² /kg² ) * (m_central) / (r)

Let's say the mass of the star is 2 x 10^30 kg and the distance of the planet from the star is 1.5 x 10^11 m.

Then, the velocity squared can be calculated as follows:

v²  = (6.67 x 10^-11 N m² /kg² ) * (2 x 10^30 kg) / (1.5 x 10^11 m)

v²  = 2.22 x 10^20 m² /s²

So, the velocity squared of the planet moving in a circular orbit around the star is 2.22 x 10^20 m² /s² .

At, last we can say if you want to find the velocity of a moving object in a circular path, use formula a. If you want to find the velocity squared of an object under the influence of a central force, use formula b.

We need to make sure that we match up the right sides before checking for proportionality.

From the picture, we can see that SRT pairs with MLN.

It's easier to see if you draw a diagram of MLN on paper with the same orientation as SRT.

Were you to do this, you would see that as SR lies on the left side of SRT, so does MLN lie on the left side of ML.

Also, both ST of SRT and MN of MLN lie on the right side and RT of SRT and LN of MLN are the base.

Thus, the proportions are

[tex]\frac{SR}{ML}=\frac{ST}{MN}=\frac{RT}{LN} \\\\\\\frac{3.61}{5.415}=\frac{2}{3} \\\\\frac{9.71}{14.564}=\frac{2}{3}\\ \\ \frac{11.97}{17.955}=\frac{2}{3}[/tex]

The area of the rectangle = length × Width

We are given that;

The expression m² + 11m + 28

Now,

Let's assume that the length of the rectangle is "m" and the width is "n".

The formula for the area of a rectangle is A = l × w. We are given that the area of the rectangle is m² + 11m + 28, so we can write:

A = m² + 11m + 28

The equation of the perpendicular bisector that goes through a segment with endpoints (2,1) and (6, -3) is y = x - 5.

In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of a line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Given:

An equation of the line that passes through the points (2,1) and (6, -3) is,

y - 1 = (-3 - 1)/(6 - 2)(x - 2)

y - 1 = -1(x - 2)

y - 1 = -x + 2

y = -x + 3

The slope of the perpendicular bisector that goes through the line y = -x + 3 is,

= -(1/-1)

= 1

And the required line passes through (2 + 6/2, 1-3/2) = (4, -1) and have slope 1,

So, the equation of the line is,

y + 1 = 1(x - 4)

y = x - 5
