define function. What are five representations of functions? Give an example of each.

Answers

Answer:

A function is a relationship between two variables, such that one variable is determined by the other variable.

A function can be represented verbally. For example, the circumference of a square is four times one of its sides.

A function can be represented algebraically. For example, 3x+6 3 x + 6 .

A function can be represented numerically.

A function can be represented graphically.

Step-by-step explanation:

The function is defined as a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

We need to define function.

What is a function?

Functions are the fundamental part of calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters such as f, g, and h. The domain is defined as the set of all the values that the function can input while it can be defined. The range is all the values that come out as the output of the function involved. Co-domain is the set of values that have the potential of coming out as outputs of a function.

Different types of a function:

The types of functions have been classified into the following four types.

Based on the set of elementsBased on equationBased on rangeBased on domain

Representation of functions:

There are three different forms of representation of functions.

Venn Diagram: The Venn diagram is an important format for representing the function. The Venn diagrams are usually presented as two circles with arrows connecting the element in each of the circles. The domain is presented in one circle and the range values are presented in another circle. And the function defines the arrows, and how the arrows connect the different elements in the two circles.

Graphical Form: Functions are easy to understand if they are represented in the graphical form with the help of the coordinate axes. Representing the function in the graphical form helps us to understand the changing behaviour of the functions if the function is increasing or decreasing. The domain of the function - the x value is represented along the x-axis, and the range or the f(x) value of the function is plotted with respect to the y-axis.

Roster Form: Roster notation of a set is a simple mathematical representation of the set in mathematical form. The domain and range of the function are represented in flower brackets with the first element of a pair representing the domain and the second element representing the range.

Therefore, the function is defined as a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

A psychologist wants to know if the difficulty of a task influences our estimate of how long we spend working at it. She designs two sets of mazes that subjects can work through on a computer. Once set has easy mazes and the other has hard mazes. Subjects work until told to stop (after 6 minutes, but subjects do not know this). They are then asked to estimate how long they worked. The psychologist has 30 students available to serve as subjects.
Describe an experiment using a completely randomized design to learn the effect of difficulty on estimated time.

Answers

Solution :

It is given that a psychologist wants to determine the difficulty of the task influences on the estimate of how long people spend working on it.

Now we have to describe a experiment by using a completely randomized design and learn the effect of the difficulty on the estimated time is by randomly assigning 15 students to a Group 1 of easy mazes and other 15 students to the second group 2 of hard mazes. And then we compare the time estimates of the two groups.

Tina is ordering pizza for a party.Peats pizza is offering a special of 4 pizza for $26. Pizza palace is selling 10 pizza for $75. If Tina need to order 40 pizza, should she order 10 orders of the 4-pizza deal or 4 orders of the 10-pizza deal?​

Answers

Answer:

She should order 10 orders of the 4-pizza deal from Peat's Pizza

Step-by-step explanation:

Peat's Pizza deal:

4 x 10 = 40 | 26 x 10 = 260 | so if you choose the Peat's Pizza deal then Tina would have to pay $260.

Pizza Palace deal:

10 x 4 = 40 | 75 x 4 = 300 | so if you choose the Pizza Palace deal then Tina would have to pay $300.

2x+2+2x-17=180 what's x?

Answers

Answer:

x= 48.75

Step-by-step explanation:

Add like terms

2x+2x and

2-17

4x-15=180

Now subtract -15 to both sides get x by itself

4x-15+15=180+15

4x=195

Now divide by four to each side to get x by itself again

4x/4 = 195/4

x=48.75

Answer:

x=48.75

Step-by-step explanation:

2x+2+2x-17=180(Group like terms)

2x+2x+2-17=180

4x-15=180(Add 15 on both sides)

4x-15+15=180+15

4x=195(Divide both sides by 4 to find the value of x)

x=48.75

A population numbers 19,000 organisms initially and grows by 4.8% each year. Suppose P represents population and t represents the number of years of growth. An exponential model for the population can be written in the form P =aâb^t where p =_________

Answers

Answer:

The exponential model for the population is [tex]P(t) = 19000e^{0.048t}[/tex]

Step-by-step explanation:

The exponential model for the population has the following format:

[tex]P(t) = P(0)e^{rt}[/tex]

In which P(0) is the initial population and r is the growth rate, as a decimal.

A population numbers 19,000 organisms initially and grows by 4.8% each year.

This means that [tex]P(0) = 19000, r = 0.048[/tex]

So

[tex]P(t) = P(0)e^{rt}[/tex]

[tex]P(t) = 19000e^{0.048t}[/tex]

The exponential model for the population is [tex]P(t) = 19000e^{0.048t}[/tex]

Answer:

114°

Step-by-step explanation:

First we have to calculate the value of c Then

3c - 84° + c = 180° <being co-interior angles >

4c - 84° = 180°

4c = 180° + 84

4c = 264°

c = 264° / 4

c = 66°

Now

<R = 3 * 66° - 84°

= 114°

<P = <R ( being opposite angles of rhombus )

<P = 114°

Answer:

[tex]S_{10} = 3069[/tex]

Step-by-step explanation:

Given

[tex]Sequence = \{3, 6, 12, 24, 48...\}[/tex]

Required

Determine the sum of the first terms

First, we calculate the common ratio (r)

[tex]r = \frac{T_2}{T_1}[/tex]

[tex]r = \frac{6}{3}[/tex]

[tex]r = 2[/tex]

The required sum is:

[tex]S_n = \frac{a(r^n-1)}{r-1}[/tex]

Substitute 3 for a, 2 for r and 10 for n

[tex]S_{10} = \frac{3(2^{10}-1)}{2-1}[/tex]

[tex]S_{10} = \frac{3(1024-1)}{2-1}[/tex]

[tex]S_{10} = \frac{3(1023)}{2-1}[/tex]

[tex]S_{10} = \frac{3(1023)}{1}[/tex]

[tex]S_{10} = \frac{3069}{1}[/tex]

[tex]S_{10} = 3069[/tex]

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtract Property of Equality

Step-by-step explanation:

Step 1: Define

250 = 4(1 - 7x)

Step 2: Solve for x

Divide both sides by 4:                    125/2 = 1 - 7xSubtract 1 on both sides:                  123/2 = -7xDivide -7 on both sides:                   -123/14 = xRewrite:                                             x = -123/14

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    250 = 4(1 - 7(-123/14))(Parenthesis) Multiply:        250 = 4(1 + 123/2)(Parenthesis) Add:              250 = 4(125/2)Multiply:                               250 = 250

Here we see that 250 does indeed equal 250.

∴ x = -123/14 is the solution to the equation.

Hello please help me through 11-13 .

Answers

Answer:

Step-by-step explanation:

Points to remember while solving a system of linear equations,

1). If the equations have same slope, solution of the system will have no solution.

2). If both the equations are same, system will have infinitely many solutions.

3). If both the equations have different coefficients of variables, system of equations will have exactly one solution.

Question 11,

ax + 4y = 10 ------ (1)

-9x - 6y = -15

-3x - 2y = -5

-6x - 4y = -10

6x + 4y = 10 -------(2)

For infinitely many solutions,

Coefficients of variables will be same.

a = 6 will be the answer.

Option B is the correct option.

Question 12,

[tex]y=-\frac{3}{2}x+4[/tex] ---------(1)

[tex]y=-\frac{3}{2}x-4[/tex] ----------(2)

Since, slopes of both the equations are same as [tex]-\frac{3}{2}[/tex], lines will be parallel.

System will have NO SOLUTION.

Question 13,

x + 3y = 6 ------- (1)

6x + 18y = 36

x + 3y = 6 -------- (2)

Both the equations are same.

Therefore, system of the equations will have infinitely many solutions.

2x - 3y = -3 ------(1)

4x + 6y = 18

2x + 3y = 9 -------(2)

Coefficients of the variables are different, therefore, one solution.

3x + 2y = 6 -------(1)

6x - 4y = 24

3x - 2y = 12 -------(2)

One solution.

8x - 10y = 6

4x - 5y = 3 -------(1)

-4x + 5y = 3

4x - 5y = -3 ------(2)

One solution.

4x + 10y = 16

2x + 5y = 8 --------(1)

10x + 25y = 40

2x + 5y = 8 --------(2)

Infinitely many solutions.

Assuming the roads go on forever, what will be the distance between the cars after 1 hours and 30 minutes in miles?

Answers

Answer:

The distance between them after 1 hour and 30 minutes will be of 63.64 miles.

Step-by-step explanation:

This question can be solved using the Pythagorean Theorem.

Both cars travel at a constant speed of 30 miles per hour. So, after 1 hour and 30 minutes, which is 1 and a half hour, they will have traveled 30*1.5 = 45 miles.

The distance between them is the hypotenuse of a right triangle, in which the sides are 45. So

[tex]d^2 = 45^2 + 45^2[/tex]

[tex]d = \sqrt{45^2 + 45^2}[/tex]

[tex]d = 63.64[/tex]

The distance between them after 1 hour and 30 minutes will be of 63.64 miles.
