We know that ;

pi or π is a Greek letter. In decimal form, the value of pi is approximately 3.14 and it is an irrational number.

According to Petr Beckmann's A History of Pi, William Jones first used this Greek letter for some purpose in 1706.  Around 30 years later, it became a standard symbol for mathematical notation.

Also ; it has been known for at least 4,000 years what Pi means. According to the history of Pi , who claims that by 2000 B.C , "the Babylonians and the Egyptians were aware about the existence and significance of this constant,"

Also ; every circle has the same ratio of circumference to diameter. Both the Babylonians and the Egyptians approximated the value of pi numerically, and later mathematicians in ancient Greece, especially Archimedes, improved these approximations.

Pi is a fundamental concept that appears in all branches of mathematics. It is a crucial concept that facilitates understanding of both universal truths and some mathematical concepts.

Thus , pi or π is a Greek word and its value is approximately 3.14 and it is an irrational number.

The expression used to verify whether g(x) is the inverse of f(x) is 6( [tex]\frac{x+1}{6}[/tex])-1  and  [tex]\frac{(6x-1)+1}{6}[/tex]

Given that f(x) = 6x-1

and g(x) = [tex]\frac{x+1}{6}[/tex]

If inverse [tex]f^{-1}[/tex] exists for a function f(x), then [tex]f(f^{-1}(x)) = f^{-1}(f(x)) = x[/tex]

So to check if g(x) is the inverse of f(x) we find f(g(x)) and g(f(x))

f(g(x)) = f( [tex]\frac{x+1}{6}[/tex]) = 6( [tex]\frac{x+1}{6}[/tex])-1 = x

and g(f(x)) = g(6x-1) = [tex]\frac{(6x-1)+1}{6}[/tex] = x

So g(x) is the inverse of f(x) and the expressions used to verify this are:

Ray's total cost was $28, 908.50

Ray Cupple bought a basic car costing at $26,500.00,

The  options costing is $725.00.

The sales tax in the state is 6%

The combined cost for license and registration fee is $50.00

Cost price of car = $26,500 and the Cost of options= $725

Therefore, the total taxable cost=$26,500+ $725=$27225

Tax amount = 6% of Total taxable cost

                    =0.06 x $27225 = $1,633.5

Total cost = $27225 + $1,633.5 + $50

Total cost = $28,908.50

Therefore Ray's total cost was $28, 908.50

would be to first subtract 3x from both sides obtaining

-4 = 4x + 8,

then subtract 8 from both sides and get

-12 = 4x.

Now divide both sides by 4 obtaining

Step-by-step explanation:

Equation of a Line: y=mx + b

Slope: 3/1 or 3

The equation of a line is a form of representing the set of points, which form a line in a coordinate system. 

The equation of a line that passes through the point (1, -4) and (2, -1) is

y = 3x - 7

The equation of a line is a form of representing the set of points, which form a line in a coordinate system. 

The general equation of a straight line is given as:

y = mx + c,

where m = slope of the line and c = y-intercept.

We have,

Two points:

(1, -4) = (a, b) and (2, -1) = (c, d)

The equation of a line can be written in the form:

y = mx + c

Slope:

m = (d - b) / (c - a) = -1 + 4 / 2 - 1 = 3 / 1 = 3

y-intercept:

Take a point (1, -4).

-4 = 3x1 + c

-4 - 3 = c

c = -7

Now,

The equation of a line is y = 3x - 7

Thus the equation of a line that passes through the point (1, -4) and (2, -1) is

y = 3x - 7

The equation of the line in point-slope form, with slope equal to -3/5 and passing through the point located at (-4 , 0), is (y - 0) = -3/5(x + 4).

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The standard form of an equation of a line is expressed as ax + by = c, where a and b, if all possible must be integers, are the coefficients of variable x and y, respectively, and c is a constant. Meanwhile, slope-intercept form is given by the formula y = mx + b, where m is the slope of the line and b is the y- intercept. On the other hand, given the slope m and a point on the line (x , y), we can express the equation in point-slope form, (y - y1) = m(x - x1).

Using the point slope form, plug in the values to set up the equation.

(y - y1) = m(x - x1)

where m = -3/5 and (x1 , y1) = (-4 , 0)

(y - 0) = -3/5(x - -4)

(y - 0) = -3/5(x + 4)

In slope-intercept form, the equation of the line is:

(y - 0) = -3/5(x + 4)

y = -3/5 x - 12/5

In standard form, the equation of the line is:

y = -3/5 x - 12/5

3/5 x + y = -12/5

Multiplying both sides by 5,

3x + 5y = -12

Step-by-step explanation:

The distance between (0,0) and (2,5) is √29.

Given,

(0,0) to (2,5)

We need to find the distance between (0,0) and (2,5).

It is given as:

If two points are (a,b) and (c,d)

d = √ ( c - a )²+ (d - b )²

Find the distance between (0,0) and (2,5).

We have,

d = √ ( 2 - 0 )² + ( 5 - 0 )²

d = √ 2² + 5²

d = √ 4 + 25

d = √ 29

Answer:

a₂ = 101.5

Step-by-step explanation:

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

given a₁ = 104 and a₃ = 99 , then

104 + 2d = 99 ( subtract 104 from both sides )

2d = - 5 ( divide both sides by 2 )

d = - 2.5

then

a₂ = 104 - 2.5 = 101.5

44th term of the sequence is -82.

In an arithmetic sequence with a₁ =2 and d=-2  

-82 = 2 + (n-1)2

n-1 = -43

n = 44

An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence. For instance, the common difference in the arithmetic series 3, 9, 15, 21, and 27 is 6.

Arithmetic sequences are sequences containing these patterns. The distance between succeeding terms in an arithmetic series is always the same. The difference between consecutive words is always two, hence the sequence 3, 5, 7, 9... is arithmetic.

An explicit formula that states a = d (n - 1) + c, where d is the common difference between succeeding words, and c = a1, can be used to establish an arithmetic sequence.

The first paycheck payment to the independent contractor is $4,615.38

Dr. salaries and wages expense $4,615.38

Cr. salaries and wages payable                     $4,615.38

What is the amount of first  bi-weekly pay to the contractors?

On the basis that there are 52 weeks in a year, hence, there would be 26 bi-weeks in a year, in order to determine the amount of first paycheck payment to the independent contractor, we simply divide the annual cost of contract by 26 bi-weeks in a year.

first paycheck payment =annual contract fees/26 bi-weeks

first paycheck payment =$120,000/26

first paycheck payment =$4,615.38

The paycheck refers to first 2 weeks which ends on on  12th January, whereas the actual payment would occur a week later on 19th of January, as a result, the amount is owed until 19th January, which means that salaries and wages expense would be debited and salaries and wages payable would be credited until actual payment is made on the 19th of January.
