The graph to use and why?

From the question, we understand that he wants to present the graph with lower increment of profit.

By comparing graphs A and B, we can see that graph A appears to have a slow increment with month, while B has a higher rate of increment.

Hence, he should use graph A

Given:

Consider the below figure attached with this question.

To find:

The value of [tex](f+g)(x)[/tex].

Solution:

The given functions are:

[tex]f(x)=|x|+9[/tex]

[tex]g(x)=-6[/tex]

Now,

[tex](f+g)(x)=f(x)+g(x)[/tex]

[tex](f+g)(x)=|x|+9+(-6)[/tex]

[tex](f+g)(x)=|x|+9-6[/tex]

[tex](f+g)(x)=|x|+3[/tex]

We know that,

[tex]|x|\geq 0[/tex]

Adding 3 on both sides, we get

[tex]|x|+3\geq 0+3[/tex]

[tex](f+g)(x)\geq 3[/tex]

So, [tex](f+g)(x)\geq 3[/tex] for all values of x.

Hence, the correct option is A.

The required a) average is 43%, b) average obesity of the United States is below the average, and c) the United States obesity is moderate.

Statistics is the study of mathematics that deals with relations between comprehensive data.

Here,

a. To determine the best estimate of the average obesity percentage for these countries.
Average = 11.4 + 74.6 / 2 = 86 / 2 = 43%.

b. The United States has an average obesity rate of 33.9%.
Since the average is 43%, so the rate of the united states is below the average.

c. How does the United States Compare to other countries?
Since the rate of obesity of the united states is moderate it lies between the interquartile ranges.

Thus, the required a) average is 43%, b) average obesity of the United States is below the average, c) the United States obesity is moderate.

Answer:

30 + 6x inches

Step-by-step explanation:

Let the required number be x

If the length of the triangle for the pool table is the twice the sum of 5 and a number

L = 2(5+x)

L = 10+2x

Since the triangle is quadilateral, this means that all sides are equal

Perimeter = 3L

Perimeter = 3(10+2x)

Perimeter = 30+6x

Hence the perimeter, in inches, of the triangle is 30 + 6x inches

There is no mode in these set of numbers.

Seven students were surveyed on the amount of money they make per hour. The results are shown below: $8.00, $8.25, $8.50, $9.00, $9.25, $10.00, $10.50 for this given data there is no mode present in the dataset.

In statistics, the mode is a measure of central tendency that represents the most frequently occurring value in a dataset. It can be used to determine the typical or common value in a given set of data. In this case, we have the hourly wages of seven students, and we need to find the mode of this dataset.

To find the mode, we need to identify the value that occurs most frequently in the dataset. Let's list the data in ascending order:

$8.00, $8.25, $8.50, $9.00, $9.25, $10.00, $10.50.

From the given data, we can observe that no value is repeated. In this case, we say that there is no mode or the dataset has no mode. Since each student earns a different hourly wage, there is no single value that appears more frequently than the others.

Mathematically, we can represent the given dataset as a set of values: {8.00, 8.25, 8.50, 9.00, 9.25, 10.00, 10.50}. The mode, denoted as "Mode(X)", is the value(s) that occur(s) most frequently in the dataset X.

In this case, Mode(X) = None or Mode(X) = ∅ (empty set).

This indicates that there is no mode present in the dataset.

It is important to note that a dataset can have more than one mode or no mode at all. When there are two or more values with the same highest frequency, the dataset is said to be multimodal. In our example, since all values occur only once, there is no mode.

In conclusion, the mode of the given dataset, which represents the most frequently occurring value, is not applicable in this case as there is no value that occurs more frequently than the others.

Answer:

B

Step-by-step explanation:

The surface area of a square pyramid is equal to: B. 64 m².

In Mathematics, the surface area of a square pyramid can be calculated by using this mathematical equation:

Surface area of square pyramid = [tex]a^2+2a\sqrt{(\frac{a}{4})^2 +h^2}[/tex]

where:

For the height, we have:

6² = h² + (4/2)²

36 = h² + 4

h² = 32

h = √32

Height, h = 5.7 m.

By substituting the given side lengths into the formula for the surface area of a square pyramid, we have the following;

Surface area of square pyramid = [tex]4^2+2(4)\sqrt{(\frac{4}{4})^2 +5.7^2}[/tex]

Surface area of square pyramid = [tex]16+8\sqrt{(1 +32)}[/tex]

Surface area of square pyramid = 64.33 ≈ 64 m².

Answer:

y=8(x+1)²-2

Step-by-step explanation:

Completing the square is a method of factorising. x²+bx+c=0 becomes x²+bx+([tex]\frac{1}{2}[/tex]b)²-([tex]\frac{1}{2}[/tex]b)²+c=0. This then gets converted to make an equation of (x+[tex]\frac{1}{2}[/tex]b)²+(-([tex]\frac{1}{2}[/tex]b)²+c)=0.

Vertex form is y=a(x-h)²+k.

8x²+16x+6=0 must first be divided by 8 to 8(x²+2x+[tex]\frac{6}{8}[/tex])=0 (as there cannot be a coefficient for x²).

This will become 8(x²+2x+[tex]\frac{2}{2}[/tex]²-[tex]\frac{2}{2}[/tex]²+[tex]\frac{3}{4}[/tex])=0.

From there, using the method above, we can convert it to 8[(x+1)²-1+[tex]\frac{3}{4}[/tex]]=0.

Solving this gets 8[(x+1)²-[tex]\frac{1}{4}[/tex]]=0.

With 8 as a, 1 as -h, and 8×-[tex]\frac{1}{4}[/tex] (-2) as k, we can input this into vertex format to get the result of y=8(x+1)²-2.

**This equation involves completing the square and vertex form, which you may wish to revise. I'm always happy to help!

Answer:

[tex](9, 8), \\(0, -7), \\(6, 3), \\[/tex]

Step-by-step explanation:

There is! Algebraically, we can find the equation of the line. Any points that the line passes through should make the equation of the line true.

In slope-intercept form, the equation of a line is given by [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope of the line, [tex]b[/tex] is the y-intercept, and [tex](x,y)[/tex] represents any point the line passes through.

The slope of a line is given by the change in y-values over the change in x-values of two points the line passes through. We're given that the line passes through the points (-6, -4) and (-3, 1).

Let:

[tex](x_1, y_1)\implies (-6, -4)\\(x_2,y_2)\implies (-3, 1)[/tex] (doesn't matter which point you assign to which)

The slope of the line that passes through these points is [tex]m=\frac{y_2-y_1}{x_2-x_1}=\frac{1-(-4)}{-3-(-6)}=\frac{5}{3}[/tex]

Now substitute [tex]m=\frac{5}{3}[/tex] and any point (x, y) that the line passes through to solve for [tex]b[/tex] in [tex]y=mx+b[/tex]:

Using (-3, 1):

[tex]1=\frac{5}{3}(-3)+b, \\\\\frac{3}{3}=-\frac{15}{3}+b,\\\\b=\frac{3}{3}+\frac{15}{3}=\frac{18}{3}=6[/tex]

Thus, the equation of the line is [tex]y=\frac{5}{3}x+6[/tex].

I just realized that it's asking for the points that the line parallel to this line and passing through point [tex]p[/tex] goes through, but I'll keep all the information above as it may be useful.

Parallel lines always have equal slopes, by definition. Therefore, the slope of the line that passes through point [tex]p[/tex] and is parallel to the line above also has a slope of [tex]5/3[/tex]. Point [tex]p[/tex] is located at (3, -2). Thus, to find [tex]b[/tex], plug in [tex]m=5/3[/tex] and [tex]x=3, y=-2[/tex] into [tex]y=mx+b[/tex]:

[tex]-2=\frac{5}{3}(3)+b, \\-2=5+b, \\b=-2-5=-7[/tex]

Therefore, the equation of this line must be [tex]y=\frac{5}{3}x-7[/tex].

You can algebraically determine if a certain point passes through this line by seeing if the point makes this equation true. From the answer choices, the following points are passed through by this line:

[tex](9, 8)\:\checkmark, \\(0, -7)\:\checkmark, \\(6, 3)\:\checkmark, \\[/tex]

Answer is below. Look at the steps to clearly understand my answer.

Now, the first time to simplifying this to add both sides by 1.

2x - 1 = 8 → 2x - 1 + 1 = 8  + 1

Since we added both sides, we'll now simplify the problem.

Add both numbers.

Lastly, we'll divide both sides of the equation by the same term.

Now, cancel both terms that are in both the numerator and denominator.

If you look back at the fraction, 2 is in  the numerator and denominator, so we'll cancel those terms.

When you cancelled the terms, you should get x = 9/2.

Any questions? Comment below.

Answer:

Hi, there the answer is [tex]x=\frac{9}{2}[/tex]

Step-by-step explanation:

Step 1: Add 1 to both sides.

2x−1+1=8+1

2x=9

Step 2: Divide both sides by 2.

2x /2 = 9 /2

x= 9 /2
