On solving the provided question, we can say that Cai's thinking expression will be area of the poster k = Ax Bt +Cz => K = x^2 + lb + 1/2wm

In mathematics, it is possible to multiply, divide, add, or remove. The construction of an expression is as follows: Expression, number, and mathematical operator Numbers, variables, and functions are the building blocks of a mathematical expression (such as addition, subtraction, multiplication or division etc.) Expressions and phrases can be contrasted. Any mathematical statement with variables, numbers, and an arithmetic operation between them is called an expression or an algebraic expression. For instance, the expression 4m + 5 has the terms 4m and 5 as well as the variable m of the supplied expression, all of which are separated by the arithmetic sign +.

The approximate number caused by secondhand smoke is 35,000.

Secondhand smoke is defined as the smoke that is inhaled by someone who is not the main smoker of the cigarette and is typically present near the main smoker while he or she is smoking.

35 000 deaths from secondhand smoke and 1000 baby deaths from maternal smoking are included in the predicted 435 000 deaths from smoking in the year 2000. Environmental tobacco smoke, often known as secondhand smoke, includes more than 7000 carcinogenic and harmful compounds.

Some studies suggest that second-hand smoke poses a greater risk due to the presence of any residue from the initial smoker's lung.

The coordinates of F' would be (2, 4). This is because F was translated 6 units to the left and 3 units up. To calculate the coordinates of F', you must subtract 6 from the x-coordinate of F and add 3 to the y-coordinate of F. Therefore, if F was (8, 1), then F' would be (2, 4).

F = (8, 1)

F' = (8 - 6, 1 + 3)

F' = (2, 4)

The coordinates of F' can be found by translating F 6 units to the left and 3 units up. To calculate the coordinates of F', you must subtract 6 from the x-coordinate of F and add 3 to the y-coordinate of F. For example, if F is located at (8, 1), the coordinates of F' would be (2, 4). This is because 8 - 6 = 2 and 1 + 3 = 4. Therefore, translating F 6 units to the left and 3 units up would result in the coordinates of F' being (2, 4). This principle applies to any initial coordinates, so you can use this method to calculate the coordinates of F' for any starting point.

The ratio of output that are two values apart is 1.09.

Q2: the function for the given table is exponantial.

A mathematical function with the form f (x) = axe is an exponential function. "x" is a variable, while "a" is a constant that serves as the function's base and must be bigger than 0. The transcendental number e, or roughly 2.71828, is the base for exponential functions that are most frequently utilized.

to find whether the functions are linear or exponential,

From the given table it is noticed that the rate of change is not constant, therefore it is not a linear function,

The general form of an exponential function is

y = abˣ

From the given table it is noticed that the function passes through the points (1,2)  and (3, 1/8). It means the equation must be satisfied by these points.

2 = ab¹

1/8 = ab³

solving the equation we get,

What is Parallelogram?

A parallelogram is a geometric object with sides that are parallel to one another in two dimensions.

A parallelogram's adjacent angles add up to 180 degrees.\

Step by step Explaination:

Measures of two angles of parallelogram are  (2a+3) and (5a+14).

As we all know , Measure of Supplementary Angles = 180°

Therefore,

(2a + 33°) + (5a+14°) = 180°

10a + 28°+ 165a+ 462° = 180°

175a +  490°= 180

175a=180-490°

175a=-310

a=310/175

a=20°

(i) 2a + 33°

= 2*20° + 30°

= 40+33°

The time required for the second lap so that the overall average speed will be 2 miles per minute is 0.6 minutes.

Speed is the distance traveled in a certain unit of time. Speed can be calculated by dividing the distance by time:

Speed = distance / time

Given information:

Distance = 2 miles

Time spent for the first track (time₁) = 2 minutes

Speed for the first lap (speed₁) = 1 mile per minute

Overall speed ([tex]speed_{t}[/tex]) = 2 miles per minute

[tex]speed_{t}[/tex] = (speed₁ + speed₂) / 2

      2 = (1 + speed₂) / 2

100 - (6)2 = 100-12 = 88

From 2015 to 2020, the population decrease, based on mathematical operations, was 12,800.

The population decrease from 2015 to 2020 is determined using multiplication and subtraction mathematical operations.

In 2015, the population increased by a growth factor of 1.08 of the 2010 figure.  

In 2020, the population decreased by a decline factor of 0.94 compared to 2015.

The city population in 2010 = 197,000

Percentage growth from 2010 to 2015 = 8%

Population in 2015 = 212,760 (197,000 x 1.08)

Percentage decrease from 2015 to 2020 = 6%

Population in 2020 = 199,994 (212,760 x 0.94)

Population decrease from 2015 to 2020 = 12,766 (212,760 - 199,994)

= 12,800 people

Thus, we can assert that the city's population decreased by 12,800 persons.

When reading a bar graph, it is important to focus on the range and size of the scale values, the value of the categories and the height of each bar, and the comparison of the height of the bars to each other. These key elements will help to accurately interpret the data represented in the bar graph.

When reading a bar graph, it is most important to remember to:

Identify the range and size of the scale values: The range and size of the scale values determine the overall spread and variability of the data represented in the bar graph. Understanding the range and size of the scale values is important for interpreting the data accurately and making comparisons between different categories or data points.

Note the value of the categories and the height of each bar: The categories and the height of each bar represent the data points in the bar graph. The categories are typically labeled on the x-axis and the height of each bar represents the frequency, count, or proportion of the data points in each category.

Compare the height of the bars to each other: Comparing the height of the bars to each other helps to identify patterns, trends, and relationships in the data. For example, if two bars have similar heights, it may indicate that the categories they represent are similar in some way, while if one bar is much taller than the others, it may indicate that the category it represents is an outlier or an exception.

It is important to remember that while bar graphs are a useful tool for visualizing categorical data, they do not provide information about the relationship between variables. To understand the relationship between variables, a scatterplot is a better choice. The standard deviation is a measure of variability in a set of data, but is not typically shown in a bar graph.

Thus, In conclusion, when reading a bar graph, it is important to focus on the range and size of the scale values, the value of the categories and the height of each bar, and the comparison of the height of the bars to each other. These key elements will help to accurately interpret the data represented in the bar graph.
