What is an equation?
In arithmetic,an equation may be a formula that expresses the equality of 2 expressions, by connecting them with the sign =.
Main body:
for option 1
initial investment is $5 after 1 year investment is
5+5/2
after 2 year 5+5/2+(5+5/2)/2=5+5/2+5/2²
continuing this way we get the formula

a researcher obtained a random sample of 100 smokers and a random sample of 100 non smokers. after interviewing all 200 participants in the study, the researcher compared the rate of depression among the smokers with the rate of depression among nonsmokers
observational study
Based on the study, the researcher may develop a hypothesis that smoking is associated with an increased risk of depression.
What is Hypothesis?An explanation that is put up for a phenomena or a group of facts is called a hypothesis. It is a speculative explanation that needs more testing and improvement because it is supported only by a small body of data. A hypothesis is not a tested theory, but rather a point of departure for more research. A hypothesis is examined in scientific study by testing and observationit. The purpose of hypothesis testing is to evaluate the likelihood that the suggested explanation is accurate and to spot any discrepancies or holes in the available data. The act of testing and improving hypotheses is a crucial component of the scientific method since it ensures that scientific ideas are supported by reliable data.
How to solve?
This hypothesis can then be tested through further research, such as conducting a larger study with more participants, or conducting experiments to evaluate the potential mechanisms by which smoking may affect the development of depression.
The researcher may also use statistical methods to analyze the data collected from the study, in order to determine the significance of the relationship between smoking and depression.
If the hypothesis is supported by the evidence, the researcher may conclude that smoking is a risk factor for depression, and may recommend interventions or preventative measures to reduce the risk of depression among smokers.

The function f(x)=∣x−3∣ can be used to determine how far a number x is away from the number 3 on the number line. Find and interpret the given function values and determine an appropriate domain for the function.
Answer:
The function f(x) = |x - 3| can be used to determine how far a number x is away from the number 3 on the number line. To find the function value for a given x, we first need to subtract 3 from x and then take the absolute value of the result. For example, if x = 5, then the function value would be f(5) = |5 - 3| = |2| = 2.
The domain of the function is the set of all possible values of x that we can plug into the function to get a real number result. In this case, the function will work for any real number value of x, so the domain of the function is the set of all real numbers, which can be written as:
Domain: (-∞, ∞)
In other words, the function f(x) = |x - 3| can be used to determine how far any real number x is away from the number 3 on the number line.

The value of x in the figure having 3 angles on a line as shown in the image attached below is 28.
The angle is formed by two rays and a common point.
To calculate the value of x using the diagram attached below:
∠AOC+∠COD+∠BOD = 180° because the sum of all the angles on a line is 180°
On substituting the values from the figure,
∠AOC=3x-7
∠COD=55
∠BOD=x+20
∠AOC+∠COD+∠BOD =3x-7+55+x+20
3x-7+55+x+20=180
4x+68=180
4x=112
x=28

Linear regression is a system of plotted points which shows a relationship between two given variables. The required linear equation is: y = 4x.
A graph is a plotted coordinate on a Cartesian plane which shows the relationship between two variables. A system of plotted points in relations to variables that shows a linear relationship is termed linear regression.
In a linear regression, the plotted points can be described by an equation:
y = bx + c
where: y is the dependent variable
x is the independent variable
b is the slope of the graph
c is the intercept
Therefore, considering the given question;
the slope of the graph = [tex]\frac{change in y}{change in x}[/tex]
= [tex]\frac{12 - 4}{3 - 1}[/tex]
= [tex]\frac{8}{2}[/tex]
slope of the graph = 4
While there is no intercept, thus intercept is zero.
Therefore, the required equation that shows the relationship between liters of water and number of minutes is:

The total addition of numbers is, 53975687481.
What is addition of numbers?
The other three fundamental arithmetic operations are subtraction, multiplication, and division. Addition is one of these four operations. The total sum or value obtained by adding two whole numbers is the result of the addition.
For the given addition first add the digits on 1st place.
7 + 7 + 7 + 7 + 2 + 2 + 2 + 1 + 8 + 7 + 1 = 51
Take 1 as it is and add 5 on the 10th place numbers.
Now add 10th place numbers,
6 + 6 + 8 + 8 + 2 + 3 + 4 + 4 + 6 + 6 + 5 = 58
Take 8 as it is and add 5 to the 100th place numbers.
Now, 9 + 9 + 9 + 1 + 2 + 4 + 4 + 0 + 7 + 4 + 5= 54
Take 4 as it is and add 5 to the 1000th place numbers.
Now, 4 + 4 + 4 + 7 + 6 + 7 + 7 + 0 + 1 + 2 + 5 = 47
Take 7 as it is and add 4 to the next addition.
Now, 9 + 6 + 7 + 4 + 8 + 3 + 1 + 2 + 4 + 4 = 48
Take 8 as it is and add 4 to the next addition.
Now, 8 + 7 + 7 + 9 + 7 + 2 + 2 + 4 = 46
Take 6 as it is and add 4 to the next addition.
Now, 7 + 6 + 6 + 2 + 6 + 1 + 3 + 4 = 35
Take 5 as it is and add 3 to the next addition.
Now, 4 + 9 + 4 + 3 + 4+ 3 = 27
Take 7 as it is and add 2 to the next addition.
Now, 7 + 4 + 2 + 4 + 2= 19
Take 9 as it is and add 1 to the next addition.
Now, 9 + 3 + 1 = 13
Take 3 as it is and add 1 to the next number.
4 + 1 = 5.
Now take the last numbers one by one from step by step.

Step-by-step explanation:

oh, my dear ...
we start at -426 ft.
swimming upwards reduces depth by adding hight.
so,
-426 + 212 = -214 ft
basically the same method is used as if we would subtract 212 from 426.
so, the diver is currently at -214 ft (214 ft below the surface).

The value of x is 13 and value of x in second question is 28, in the angle of line. The angle between a line's inclination and the x-axis's positive direction is known as the inclination.
How do you calculate inclination?The angle between a line's inclination and the x-positive axis's direction is known as the inclination. This angle's value ranges from 0° to 180°. It is measured counterclockwise around the positive x-axis direction. The slope of a line is the tangent of the angle of inclination if the inclination angle is known. Take the tangent of the angle produced between the line and the x-axis to get the degree of inclination.Angle B, which is the opposite of angle A and measures 100 degrees, will also be 100 degrees. This indicates that the sum of the two angles is 200 degrees.From first fig :
26° = 2x °
x = 26 / 2 = 13
Second fig :
134° = 4x + 22

Answer:
the points that will fall on a line where the constant of proportionality is k are A) (6,8) and B) (3,2).
Step-by-step explanation:
A point (x,y) falls on a line where the constant of proportionality is k if y is equal to k times x. In other words, the equation for the line is y = kx.
Given this, we can determine which of the given points fall on a line where the constant of proportionality is k by evaluating whether the y-coordinate of each point is equal to k times the x-coordinate.
For example, if k = 2, then the point (6,8) falls on the line y = 2x because 8 is equal to 2 times 6. Similarly, the point (3,2) falls on the line y = 2x because 2 is equal to 2 times 3.
On the other hand, the point (6,4) does not fall on the line y = 2x because 4 is not equal to 2 times 6.
Therefore, the points that will fall on a line where the constant of proportionality is k are A) (6,8) and B) (3,2).
Note that if k is not specified, then any of the given points could potentially fall on a line where the constant of proportionality is k, depending on the value of k.

How to prove the right angle?A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly known as a rectangled triangle, is a triangle with one right angle, i.e. two perpendicular sides. Trigonometry is founded on the relationship between the sides and other angles of a right triangle.
In this case, the values given are 5, 12 and 13. This will be illustrated thus:
