A small group communication occurs when three or more people work together interdependently for the purpose of accomplishing a task.

Small Group Communication

Small group communication is the term used to describe face-to-face conversation between more than two people. This kind of internal communication exists.

A small group is typically thought of as a collection of three or less people, with a maximum number of twelve to fifteen. A group would not be considered tiny if it had more than fifteen members or if it had just two.

Since almost all businesses and organisations employ people in small squads, there are advantages or even strengths to small group communication. When compared to one individual working alone on a project, it has been found to be more appropriate and produce better results.

The most effectively provide the desired primary data is experimentation

Experimentation is the step in the scientific method that helps people decide between two or more competing explanations—or hypotheses. These hypotheses suggest reasons to explain a phenomenon or predict the results of an action.

With an experiment, you run a test and see what the results are. If you don't get good results, you can try another option, and run another test. Then you can see what the outcomes of the choices are (the info you didn't have when first thinking about the decision), and you can make a better-informed decision now.

B. graph of a right triangle with hypotenuse beginning at negative 3 comma negative 13 and ending at 11 comma 9.

What is distance between two points?

The distance between two points in a plane is the length of the line segment separating the two points. Typically, the equation

d=√((x2 - x1)^2 + (y2 - y1)^2) is used to calculate the distance between two points.

Suppose we have a pair of points, with the coordinates given as follows:

[tex](x_1, y_1)[/tex]  and  [tex](x_2, y_2)[/tex].

The two points form a right triangle, in which the sides are given as follows:

[tex]y_2-y_1\\x_2-x_1[/tex]

The distance between these two points is given by the hypotenuse of the right triangle.

Hence, applying the Pythagorean Theorem, the distance is obtained as follows:

[tex]d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}[/tex]

In this problem, the coordinates of the points are given as follows:

(−3, −13) and (11, 9).

The values of a such that the linear equation 2 · a - 4 · x = 4 - a² · x have a solution in the interval (- 8, - 2) is a = 2 and - 7 / 4 ≤ a ≤ - 1.

In this problem we find the case of a linear equation whose values of variable a must be determined in terms of an interval of values of variable x. First, write the defined equation:

2 · a - 4 · x = 4 - a² · x

Second, form the standard form of a quadratic equation in terms of a:

x · a² + 2 · a - 4 · (x + 1) = 0

Third, use the quadratic formula:

a = - 2 / (2 · x) ± [1 / (2 · x)] · √[4 - 4 · x · [- 4 · (x + 1)]]

a = - 1 / x ± (1 / x) · √[1 + 4 · x · (x + 1)]

a = - 1 / x ± (1 / x) · √(4 · x² + 4 · x + 1)

There are two cases for the given interval:

Case 1

a = - 1 / x + (1 / x) · √(4 · x² + 4 · x + 1)

x = - 8

a = - 1 / (- 8) + [1 / (- 8)] · √[4 · (- 8)² + 4 · (- 8) + 1]

a = - 7 / 4

a = - 1 / (- 2) + [1 / (- 2)] · √[4 · (- 2)² + 4 · (- 2) + 1]

a = - 1

Case 2

a = - 1 / x - (1 / x) · √(4 · x² + 4 · x + 1)

x = - 8

a = - 1 / (- 8) - [1 / (- 8)] · √[4 · (- 8)² + 4 · (- 8) + 1]

a = 2

a = - 1 / (- 2) - [1 / (- 2)] · √[4 · (- 2)² + 4 · (- 2) + 1]

The slope of the line perpendicular to 4x - 6y = - 60 is (-3/2).

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is

y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

We know lines perpendicular to each other have slopes that are negative reciprocals of each other.

Given line is 4x - 6y = - 60 ⇒ - 6y = - 4x - 60 ⇒ y = (2/3)x + 10.

Answer:

Parabolas

A quadratic function is a function that can be written in the form f(x)=ax2+bx+c

where a,b, and c are real numbers and a≠0

. This form is called the standard form of a quadratic function.

The graph of the quadratic function is a U-shaped curve is called a parabola.

The graph of the equation y=x2

, shown below, is a parabola. (Note that this is a quadratic function in standard form with a=1 and b=c=0

.)

In the graph, the highest or lowest point of a parabola is the vertex. The vertex of the graph of y=x2

is (0,0)

.

If a>0

in f(x)=ax2+bx+c, the parabola opens upward. In this case the vertex is the minimum, or lowest point, of the parabola. A large positive value of a makes a narrow parabola; a positive value of a which is close to 0

makes the parabola wide.

If a<0

in f(x)=ax2+bx+c, the parabola opens downward. In this case the vertex is the maximum, or highest point, of the parabola. Again, a large negative value of a

makes the parabola narrow; a value close to zero makes it wide.

For an equation in standard form, the value of c

gives the y

-intercept of the graph.

The line that passes through the vertex and divides the parabola into two symmetric parts is called the axis of symmetry.

The equation of the axis of symmetry for the graph of y=ax2+bx+c

, where a≠0, is x=−b2a

In all the above graphs, the axis of symmetry is the y

-axis, x=0. In the graphs below, the axis of symmetry is different (marked in red.) Note that c still gives the y

-intercept.

If you write a quadratic function like x=f(y)=ay2+by+c

, where x is a function of y (instead of a y as a function of x

), you get a parabola where the axis of symmetry is horizontal.

Note that in this case, c

is the x-intercept. If a is positive, the graph opens to the right; if a

is negative, the graph opens to the left.

Example:

Write the equation of the axis of symmetry, and find the coordinates of the vertex of the parabola y=−3x2−6x+4

.

The equation of the axis of symmetry for the graph of y=ax2+bx+c

.

x=−b2a

Substitute −3

for a and −5 for b

in the equation of the axis of symmetry.

x=−−62(−3)    =−1

So, the equation of the axis of symmetry is x=−1

.

Since the equation of the axis of symmetry is x=−1

and the vertex lies on the axis, the x-coordinate of the vertex is −1

.

To find the y

-coordinate of the vertex, first substitute −1 for x

in the given equation.

y=−3(−1)2−6(−1)+4

Simplify.

y=−3+6+4    =7

Therefore, the coordinates of the vertex of the parabola is (−1,7)

.

-x - 24= -34

2. Add 24 to both sides

-x - 24= -34

-x - 24= -34

With the use of regression analysis, you may determine which of the independent factors actually has an effect statistically and learn how the dependent variable changes when one of the independent variables changes.

Regression analysis is used in statistical modeling to determine the associations between two or more variables:

The fundamental element you are attempting to comprehend and anticipate is the dependent variable. The elements that could have an impact on the dependent variable are known as independent variables.

Regression analysis enables you to statistically ascertain which of the independent variables actually has an impact and explains how the dependent variable changes when one of the independent variables changes. There is a difference between a simple and multiple linear regression in statistics. A dependent variable and one independent variable are modeled using a linear function in simple linear regression. Multiple linear regression is used when there are two or more explanatory variables used to predict the dependent variable.

The price of reusable tote bags and the interest rate may change over time, which could affect the length of time that Dariya's savings will last.

What is the interest rate?

The proportion of a loan that is charged as interest to the borrower is typically expressed as an annual percentage of the loan outstanding.

If Dariya deposits $4,000 into a savings account with an annual nominal interest rate of 5%, the amount of interest she earns each year will be $4,000 * 5% = $200.

If the price of a reusable tote bag is $10.00 and Dariya wants to buy one every year, the cost of buying one reusable tote bag every year will be $10.00/year.

To determine how long Dariya's savings will last, you can divide the amount of her annual interest earnings by the cost of buying a reusable tote bag each year.

In this case, Dariya's savings will last for 200/10 = 20 years.

Keep in mind that this calculation assumes that the price of reusable tote bags remains constant at $10.00/year and that the nominal interest rate remains fixed at 5% per year.

Hence, the price of reusable tote bags and the interest rate may change over time, which could affect the length of time that Dariya's savings will last.
