The Range and Domain for the apples as per the given information is (1, 20) and (1, 20).

The difference between the greatest and lowest values of a set of integers is defined as its range. To find it, subtract the distribution's lowest number from its highest.

Because the term "range" can have multiple meanings, it is recommended that it be defined the first time it is used in a textbook or article. When older books use the term "range," they usually indicate what is currently known as the codomain. More recent works, if they use the phrase "range," usually use it to refer to what is now known as the picture. A number of current books avoid using the word "range" entirely to avoid confusion.

Given,

We need to spend $20 for each apple

And also given that,

The cost of each apple is $1

Here the independent variables are apples

Range=(1, 20)

Domain=(1, 20)

Answer:

The table in the attached figure N 1

The graph in the attached figure n 2

Step-by-step explanation:

we have

x+2=y

we know that

To graph a linear equation the best way is plot the intercepts

Find the y-intercept

The y-intercept is the value of y when the value of x is equal to zero

For x=0

0+2=y

y=2

The y-intercept is the point (0,2)

Find the x-intercept

The x-intercept is the value of x when the value of y is equal to zero

For y=0

x+2=0

x=-2

The x-intercept is the point (-2,0)

Find additional points to create a table (is not necessary for plot the line)

Answer:

[tex]\textsf{Vertex form}: \quad f(x)=(x-4)^2+2[/tex]

[tex]\textsf{Standard form}: \quad f(x)=x^2-8x+18[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{5.6 cm}\underline{Vertex form of a quadratic equation}\\\\$y=a(x-h)^2+k$\\\\where:\\ \phantom{ww}$\bullet$ $(h,k)$ is the vertex. \\ \phantom{ww}$\bullet$ $a$ is some constant.\\\end{minipage}}[/tex]

From inspection of the given graph:

Substitute the vertex and point (0, 18) into the vertex formula and solve for a:

[tex]\begin{aligned}y&=a(x-h)^2+k\\\implies 18&=a(0-4)^2+2\\18&=a(-4)^2+2\\18&=16a+2\\16a&=16\\a&=1\end{aligned}[/tex]

Substitute the found value of a and the vertex into the formula:

[tex]\implies y=1(x-4)^2+2[/tex]

[tex]\implies f(x)=(x-4)^2+2[/tex]

To write the equation in standard form, expand the brackets:

[tex]\implies f(x)=(x-4)^2+2[/tex]

[tex]\implies f(x)=(x-4)(x-4)+2[/tex]

[tex]\implies f(x)=x^2-8x+16+2[/tex]

(q * r)(5) = 96

From the question, we have the following functions that can be used in our computation:

q(x) = x² + 7

r(x) = √(x + 4)

The composite functions are given as

(r * q)(5) and (q * r)(5)

The base functions of the above composite functions are

(r * q)(x) and (q * r)(x)

And they are calculated using

(r * q)(x) = r(x) * q(x)

(q * r)(x) = q(x) * r(x)

Substitute the known values in the above equations

So, we have the following equations

(r * q)(x) = (x² + 7) * (√(x + 4))

(q * r)(x) = (√(x + 4)) * (x² + 7)

Substitute 5 for x

(r * q)(5) = (5² + 7) * (√(5 + 4))

(q * r)(5) = (√(5 + 4)) * (5² + 7)

Evaluate the equations

(r * q)(5) = 96

The equation of the line that is parallel to the line y = 1/2x + 2 is: y = 1/2x + 5/2.

Recall that if two lines are parallel, they will have the same slope (m).

Slope of a line (m) = change in y / change in x.

The slope (m) of the equation, y = 1/2x + 2, that represents a line is 1/2.

This means that the line that is parallel to it will also have a slope (m) that is equal to 1/2.

Find the y-intercept by substituting m = 1/2 and (x, y) = (1, 3) into y = mx + b:

3 = 1/2(1) + b

3 = 1/2 + b

3 - 1/2 = b

5/2 = b

b = 5/2

To write the equation of the parallel line, substitute m = 1/2 and b = 5/2 into y = mx + b:

The value of c is 0 guaranteed by the Mean Value Theorem for Integrals for the function 2x+1 on the interval [3,6].

Mean value theorem states, roughly, that for a given planar arc between two endpoints, there is at least one point at which the tangent to the arc is parallel to the secant through its endpoints.

Given.

Function is 2x+1 on the interval [3,6]

f(x)=2x+1

f(x) continuous on [3, 6] and differentiable on (3, 6) so the MVT applies here.

f(3)=7

f(6)=13

Average rate of change of f on [3,6]

= (13-7) / (6-3) = 6/3=2

To find the c-value guaranteed by the MVT, such that the instantaneous rate of change when x = c is 2, we differentiate, set f'(x) = 2, and solve:

f'(x) = 2 and x = 1.

c = 0 is the only c-value in the interval at which the instantaneous rate of change = the average rate of change.

Answer:

h = 4.5

Step-by-step explanation:

16.5 + 2.75h = 9h + 7.5 − 4.25h

Combine like terms on the right side.

16.5 + 2.75h = 4.75h + 7.5

Subtract 4.75 h from both sides.

16.5 - 2h = 7.5

Subtract 16.5 from both sides.

-2h = -9

Divide both sides by -2.

h = 4.5

Answer:

h = 1.2

Step-by-step explanation:

1.) Isolate the variable H. To isolate the variable H, you have to move numbers onto one side and variable onto another. I will show this process in the next steps:
2.) First, move the numbers onto one side. You will subtract 7.5 on both sides, ending up with 16.5 - 7.5 + 2.75h = 9h - 4.25h.

3.) Now, move the variable to one side. You will subtract 2.75h on both sides, and get 16.5 - 7.5 = 9h - 4.25h + 2.75h.

4.) Finally, Simplify. 16.5 - 7.5 = 9. 9h - 4.25h + 2.75h = 7.5h. Therefore, 7.5h = 9.
5.) If we divide both sides by 7.5, we get h = 9/7.5, which is 1.2. By this, h = 1.2

Step-by-step explanation:

Let the larger number be x and smaller number be y.

x = 18 + 2y ----------------(1)

x + y = 93 -----------------(2)

Put Eq. (1) in Eq. (2)

18 + 2y + y = 93

You are adding two negative numbers.

When you add two positive numbers or two negative numbers, just ignore the signs and add the numbers as positive numbers. Then the answer has the same sign as the original numbers.

Step 1. Ignore the signs and make both numbers positive.

Add 2/7 and 4/7.

2/7 + 4/7 = 6/7

Step 2. Since the two numbers are originally negative, the answer is negative.

(-2/7) + (-4/7) = -6/7

#2. 5.4 + (-8.6)

When you add a positive number and a negative number, first make both numbers positive. Then, subtract the smaller positive number from the larger positive number. Finally, the answer has the same sign as the original number that corresponds to the larger positive number.

Here we do it step by step.

5.4 + (-8.6)

Step 1. Make both numbers positive. The numbers now are:

5.4 and 8.6

Step 2. Subtract the smaller positive number from the larger positive number.

8.6 - 5.4 = 3.2

Now look at the two positive numbers. 5.4 and 8.6. The larger number is 8.6. The original number that 8.6 came from is -8.6, a negative number, so the answer is negative.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The data of mathematics students is,

60 study French, 30 study French and German

55 study German, 25 study French and Russian

75 study Russian, 35 study German and Russian

12 students study all the three languages.

Now,

Let F, G, R denote the set of students studying French, German and Russian respectively.

And, The data of mathematics students is,

n (F) = 60, n (F ∩ G) = 30

n (G) = 55, n (F ∩ R) = 25

n (R) = 75 , n (G ∩ R) = 35

n (F ∩ G ∩ R) = 12

Since, We know that;

⇒ n (FUGUR) = n (F) + n (G) + n (R) - n (F ∩ G) - n (F ∩ R) - n (G ∩ R)

                        + n (F ∩ G ∩ R)

Substitute all the values, we get;

⇒ n (FUGUR) = n (F) + n (G) + n (R) - n (F ∩ G) - n (F ∩ R) - n (G ∩ R)

                        + n (F ∩ G ∩ R)

⇒ n (FUGUR) = 60 + 55 + 75 - 30 - 25 - 35 + 12

⇒ n (FUGUR) = 112

Thus, The value of n (FUGUR) will be;
