The value of angle with x, given the equation on the circle, is 4) 3.

The angle is given by the expression:
31x + 3

The same angle is shown to be a right angle with the line EF being straight and therefore a right angle. Right angles have a total measure of 90 degrees.

The value of x can therefore be found by equating the expression to 90 degrees:
31x + 3 = 90

31 x = 90 - 3

x = 87 / 31

(-π/2 , π/2) is the restricted domain on the tangent function that allows us to build the arctangent (inverse tangent) function.

As, we know that the Tangent function is neither an One-One nor Onto function. So, the domain should be restricted to obtain the inverse function of the Tangent function.

Domain of the tangent function be, R - {(2n+1)π/2}

Range of the tangent function be, R

Now, to build the inverse tangent function we have to restrict the domain so that, the function will be one-one and onto both.

So, the restricted domain be (-π/2 , π/2).

In the domain (-π/2 , π/2), the tangent function is one-one and onto both and hence, we can build the inverse tangent function i.e. arctangent.

So, (-π/2 , π/2) is the restricted domain on the tangent function that allows us to build the arctangent (inverse tangent) function.

The diameter of the circle is 4.45 units.

What is circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. Every line that passes through the circle forms the line of reflection symmetry. Also, it has rotational symmetry around the centre for every angle.

A line segment having both the endpoints on the circle and is the largest chord of the circle is called diameter.

Given,

the circumference of circle = 14 units

circumference = πd

What are the 3 trignometric identities?

The right-triangle theorem, also known as Pythagoras theorem, is the foundation for the three Pythagorean trigonometric identities.

[tex]sin^{2}a+cos^{2}a=1[/tex]

[tex]1+tan^{2}a=sec^{2}a[/tex]

[tex]cosec^{2}a=1+cot^{2}a[/tex]

The reciprocal trigonometric identities are:

Sin θ = 1/Cosec θ or Cosec θ = 1/Sin θ

Cos θ = 1/Sec θ or Sec θ = 1/Cos θ

Tan θ = 1/Cot θ or Cot θ = 1/Tan θ

tan 15 = tan(45 - 30)

As tan(A - B) = (tanA - tanB)/(1 + tanAtanB)

tan15 = tan(45 - 30) = (tan45 - tan30)/(1 + tan30tan45)

                   = [tex]\frac{1 - \sqrt{3} }{1+\sqrt{3} }[/tex]

                   = [tex]\frac{1-\sqrt{3} }{1+\sqrt{3} }[/tex]   ×   [tex]\frac{1 - \sqrt{3} }{1-\sqrt{3} }[/tex]

                   = [tex]\frac{(1-\sqrt{3}) ^{2} }{1-\sqrt{3} ^{2} }[/tex]

                  =  [tex]\frac{(1-\sqrt{3}) ^{2} }{1-3}[/tex]

The probability Professor elderman's class of 36 has a class average below 78 is 0.9987.

Given that;

In his principles of microeconomics subject, Professor Elderman has utilized the same multiple-choice final exam for many years. He looks over the last ten years' worth of statistics and discovers that the scores have a mean of 76 and a standard deviation of 12.

µ = 76 , σ = 12 , n = 36

Using Normal Distribution;

For x = 70

z = (x - µ) / (σ/√n) = (70-76)/(12/√36) = -3.00

P( average greater than 70 ) = P(X>70)

                                               = 1 - P(X<70)

                                               = 1 - P(Z<-3.00)

                                               = 1 - 0.0013

After 10 days, the expected number of shoppers at the shopping mall is 163.

It is given that the number of shoppers increases daily by 5% from the number of shoppers the previous day.

As we can see that the increase in the number of shoppers is going to change every day, and the above case is compounded daily.

The formula of compound increase is

Amount = Base X (1 + r/n)ⁿˣ

where,

Base = original amount

r = rate of change

n = no. of times the change occurs in the time period

t = time

Here,

Base = 100

r = 5/100

n = 1, since it changes once every day

x = 10

Therefore we get

The old monthly payment was =  9.27 x 50 = 463.5

The new monthly payment is = 11.10 x 50 = 555

The percent increase in his monthly payment is 1.947%

Given,

Sandra Williams bought a home with a 10.25% adjustable rate mortgage for 25 years. She paid $9.27 monthly per thousand on his original loan

According to the question:

So, per thousand value of $65000 is 50000/1000 =50

Now, the old monthly payment was =  9.27 x 50 = 463.5

She decides to renew and will now pay $11.10 monthly per thousand on his loan.

So, the new monthly payment is = 11.10 x 50 = 555

The percent increase in his monthly payment is= 11.10 /9.27 - 1 x 100

19.7411 % and to nearest tenth it is 1.947%

Hence, the old monthly payment was =  9.27 x 50 = 463.5

Total pre-split Market Capitalization is $1,08,125,000.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

Williams and Co. is splitting their stock at a ratio of 3:1. The pre-split price is $43.25 and the pre-split number of shares is 2.5 million.

Total Value of Shares = $43.25 Share Price × 2.5 × 10⁶ Shares

Total Value of Shares = $1,08,125,000

Let’s say the company’s board decides to approve a 3-for-1 split.

Total Shares = 2.5 × 10⁶ × 3 = 75,00,000

Share Price = $43.25 ÷ 3 = $14.416

Total Value of Shares = $14.416 Share Price × 75,00,000 Shares

Total Value of Shares = $1,08,120,000

[tex]\sf \dfrac{1}{2}-\dfrac{1}{8}=\dfrac{\boxed{4}}{8}-\dfrac{1}{8}=\dfrac{\boxed{3}}{\boxed{8}}[/tex]

Step-by-step explanation:

When adding or subtracting fractions that have different denominators, first rewrite the fractions as equivalent fractions with the same denominator.  To do this, find the lowest common multiple (LCM) of the denominators.

The given subtraction is:

[tex]\sf \dfrac{1}{2}-\dfrac{1}{8}[/tex]

The LCM of the denominators 2 and 8 is 8.  Therefore, we need to rewrite the first fraction as an equivalent fraction with 8 as its denominator.  To do this, multiply its numerator and denominator by 4:

[tex]\implies \sf \dfrac{1}{2} \times\dfrac{4}{4}=\dfrac{4}{8}[/tex]

Therefore:

[tex]\implies \sf \dfrac{1}{2}-\dfrac{1}{8}=\dfrac{4}{8}-\dfrac{1}{8}[/tex]

To subtract fractions with the same denominator, simply subtract the numerators. (The denominator stays the same).

[tex]\implies \sf \dfrac{1}{2}-\dfrac{1}{8}=\dfrac{4}{8}-\dfrac{1}{8}=\dfrac{4-1}{8}=\dfrac{3}{8}[/tex]

Final solution

The value of x and y which is on midsegment of the triangle is 1 and 11.

What is midsegment?

 A triangle's midsegment is the section of the triangle's shape that connects the midpoints of its two sides. a section of a line connecting the midpoints of two triangle's sides. There are three possible midsegments in a triangle. The section of a line between the midpoints of two triangle sides is known as a midsegment. Due to the fact that triangles have three sides, they also have three midsegments. A line drawn by joining the midpoints of any two of a triangle's sides is known as the midsegment.

let us assume triangle as ABC and DE is the midsegment .

Where  DE=2x+1 and BC = 8x-2 .

According to the midsegment theorem ,

=> DE = 1/2 BC

=> 2x+1 = 1/2(8x-2)

=> 2x+1=4x-1

=> 2x=2

=> x=1

Now AB divided intp AD=3z and DB=z+22

Then, AD=DB

=> 3z = z+22

=> 2z = 22

=> z = 11.
