Answer:

B. 3x10^4

Step-by-step explanation:

9x10^-8 = 0.00000009

3x10^-12 = 0.000000000003

0.00000009 / 0.000000000003 = 30,000

3x10^4 = 3x10,000 = 30,000

For given equilateral triangle ΔRST, x = 2. And the measure of each side is 11 units.

In given question,

ΔRST is equilateral triangle.

We have been given some information about sides of ΔRST.

RS is three more than four times x.

We write above statement as mathematical expression.

RS = 3 + 4x

ST is seven more than two times x.

We write above statement as mathematical expression.

ST = 7 + 2x

and TR is one more than five times x.

We write above statement as mathematical expression.

TR = 1 + 5x

We need to find the value of x.

Since ΔRST is an equilateral triangle, RS = ST = RT

⇒ 3 + 4x = 7 + 2x = 1 + 5x

Consider 3 + 4x = 7 + 2x

⇒ 4x - 2x = 7 - 3

⇒ 2x = 4

⇒ x = 2

Now we find the measure of each side.

RS = 3 + 4x

RS = 3 + 4(2)

RS = 11 units

But RS = ST = RT

So, the measure of each side is 11 units.

Therefore, for given equilateral triangle ΔRST, x = 2. And the measure of each side is 11 units.

The Final value for the given question is 11 /5.

x / 11 = 13 / 65 is the given expression.

Here, we must determine the value of 'x' in the preceding expression.

We get by multiplying '11' on both sides

= x * 11 / 11 = 13 * 11  / 65

By canceling common numbers on the numerator and denominator we get

= x  = 13 * 11 / 65

= x = 11 / 5

Therefore, the correct value for x is 11 /5.

AB has a magnitude of 9√6 according to estimates.

AB's vector direction is given as Ф = 84.80° (angle which lies in the 4th quadrant with clockwise direction).

In complex numbers, the distance formula is employed to demonstrate the plane as well as its magnitude. Furthermore, distance formulas can be used to calculate the distance between two planes in three-dimensional and n-dimensional planes.

Now, in response to the given question;

J and K have (-1,10) and (1,-12) coordinates, respectively.

The distance formula for the points A and B is as follows:

AB² = (x₂ - x₁)² + (y₂ - y₁)²

AB = √[(x₂ - x₁)² + (y₂ - y₁)²]

The coordinates for the points A and B's  are-

(x₁,y₁) = (-1,10)   and (x₂,y₂) = (1,-12).

Substituting the given values in the distance formula;

AB = √[(1 + 1)² + (-12 - 10)²]

AB = √[(2)² + (-22)²]

AB = √[4 + 484] = √486

AB  = 9√6 (magnitude of the vector AB)

Estimate this same vector AB's direction now. The direction of a vector is defined by the angle formed by it with a horizontal line.

To determine the direction of a vector, utilize one of the formula given.

tan Ф = Δy/Δx

Where, x = horizontal change

and, y = vertical change

tan Ф = (y₂ - y₁)/(x₂ - x₁)

       = (-12 - 10)/(1 + 1)

tan Ф = -22/(2) = -11

Ф = 84.80°  (angle which lies in the 4th quadrant with clockwise direction).

As a result, this same distance between A and B is discovered to be 9√6 (the same as the magnitude of a given vector AB).

According to estimates, FG has a magnitude of 2√5.

The vector direction of FG is given as = 63.43°. (angle formed in the 1st quadrant with anti-clockwise direction).

The distance formula is used in complex numbers to show the plane in addition to its magnitude. Distance formulas can also be used to determine the actual the distances between two planes in three- and n-dimensional planes.

Now, in answer to the question posed;

F and G have coordinates of (-1,10) and (1,-12), respectively.

The formula for calculating the distance between points A and B is as follows:

FG² = (x₂ - x₁)² + (y₂ - y₁)²

FG = √[(x₂ - x₁)² + (y₂ - y₁)²]

The coordinates for the points F and G's  are-

(x₁,y₁) = (-4,0)   and (x₂,y₂) = (-6,-4).

Substituting the given values in the distance formula;

FG = √[(-6 + 4)² + (-4 + 0)²]

FG = √[(-2)² + (-4)²]

FG = √[4 + 16] = √20

FG  = 2√5 (magnitude of the vector FG)

Estimate the direction of this same vector FG now. The angle formed by a vector with a horizontal line defines its direction.

Use one of the following formulas to calculate the direction of a vector.

tan Ф = Δy/Δx

Where, x = horizontal change

and, y = vertical change

tan Ф = (y₂ - y₁)/(x₂ - x₁)

      = (-4 + 0)/(-6 + 4)

tan Ф = -4/(-2) = 2

Ф = 63.43°  (angle lies with in the first quadrant with anticlockwise direction).

As a result, the distance between F and G is determined to be 2√5. (the same as the magnitude of a given vector FG).

Step-by-step explanation: The way to divide this is putting it this way 2432/8.

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.

The recursive definition for Q is Q(n) = Q(n-1) + 1.5

It refers to a "series where the deviations between every subsequent term are exactly the same" (or) "each term is acquired by adding a specific number (positive, negative, or zero) to its preceding term."

We have three values of sequence:

Q(1)=4

g(3)=7

Q(7)=13

Let us assume the sequence to be an arithmetic sequence

The n-th term of any arithmetic sequence is determined by:

[tex]a_{n}[/tex] = a+(n-1) d

Q(3)=Q(-1)+(3-1)d

7 =4+2d

2d = 3

d = 3/2

d = 1.5

Now, Q(7) = Q(1) + (-1)d

13 = 4+6 d

6d = 9

d = 9/3

d = 1.5

So, the d is the same for both terms.

Therefore, this is an arithmetic sequence.The recursive relation is given as [tex]a_{n}[/tex] = a(n-1)d.

Then, the recursive definition for Q is Q(n) = Q(n-1) + 1.5.

The independent variable is time on the x axis and the dependent variable is distance on the y-axis.

When making a time graph, the independent variable is the variable that is shown by the x-axis. Time will usually be the independent variable because we cannot change time so we watch for the changes in other things as time goes on.

In this case therefore, the independent variable is time which will be shown as the x-values. The dependent variables would then be the distance which would be the y-values.
