Using translation concepts, we have that:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

In this problem, the vertices of the pre-image are given as follows:

D(-5,2), E(1,5), F(0,-1).

The vertices of the transformed image are given by:

D'(-2, -5), E'(-5,1), F(1,0).

From this, we the rule is given by:

(x,y) -> (-y,x).

Which is equivalent to the rotation rule of a rotation of 270º clockwise.

Step-by-step explanation:

The expression used to calculate how many more seconds Tatenda spends than Ciara spends mowing lawns during 4 weeks is 4(700t- 750c) .

What is an expression in math example?

time taken by tatenda to mow a square meter of lawn = t seconds

time taken by Ciara  to mow a square meter of lawn = c seconds

area mowed by tatenda in a week = 700 square meters

area mowed by Ciara in a week = 750 square meters

the expression used to calculate how many more seconds Tatenda spends than Ciara spends mowing lawns during 4 weeks

time taken by tatenda for mowing in 4 weeks = 4 * 700 * t seconds

time taken by Ciara for mowing in 4 weeks = 4 * 750 * c seconds

more seconds Tatenda spends than Ciara spends mowing lawns during 4 weeks = [4 * 700 * t ] - [4 * 750 * c]

= 4(700t- 750c)

Therefore, the expression used to calculate how many more seconds Tatenda spends than Ciara spends mowing lawns during 4 weeks is 4(700t- 750c).

The mean absolute deviation of the data is 0

Given that

          24, 26, 28, 28, 30, 30, 32, 32, 34,36

To find

So, according to the question

We have,

          24, 26, 28, 28, 30, 30, 32, 32, 34,36

                    [tex]mean = \frac{sum\;of\;data}{number\;of\;data}[/tex]

                              = [tex]\frac{24+26+ 28+ 28+ 30+30+ 32+ 32+ 34+36}{10}[/tex]

                              = [tex]\frac{300}{10}[/tex]

      mean of data = 30

For mean absolute deviation of the data, first we have to find the difference of each data value from mean of data.

So,

      24 - 30 = -6

      26 - 30 = -4

      28 - 30 = -2

      28 - 30 = -2

      30 - 30 =  0

      30 - 30 =  0  

      32 - 30 =  2

      32 - 30 =  2

      34 - 30 =  4

      36 - 30 =  6

                   ∑D = | (-6-4-2-2+0+0+2+2+4+6) |

                   ∑D = 0

                MAD  = [tex]\frac{The \;sum \; of \; data \;after \; subtracting \;it's \;mean }{number \;of \;data}[/tex]

                MAD  = [tex]\frac{\sum D}{10}[/tex]

Chlorine will be more reactive.

From the question, we are to predict whether the atoms of chlorine or atoms of sulfur would be more likely to attract electrons

The electronic configuration of chlorine (Cl) is

2,8,7

This means Cl needs only one electron to complete its octet configuration

and

The electronic configuration of sulfur (S) is

2,8,6

This means sulfur needs two more electrons to complete its octet configuration

Since chlorine needs fewer electrons to complete its octet configuration, then it will be more likely to attract electrons.

The total number of games won by Jamie is not 11 according to the conditions given in the question.

What is an equation?

The equation is illustrated as a mathematical statement having an equal symbol in between two expressions, '='. It depicts that both sides of the equal sign are equal to each other.

Calculation of the number of games played by Jamie

Let us assume that x and y be the number of games that Jamie and Imani have won

According to the question, Imani has won 5 fewer games than Jamie i.e.

y = x - 5    —-- 1

The total number of games won by Jamie and Imani together is 30

x + y = 30

Using equation 1, put the value of y,

x + x - 5 = 30

2x - 5= 30

Now, substitute x by 11, and we get that the equality does not net

Thus, we can conclude that 11 is not the number of games won by Jamie

Hence, the total number of games won by Jamie is not 11 using the given equations.

the inequality is:

$38 + $3*x < $80

And the solution is:

x < 14.

We know that Violet's plan has a flat cost of $38 plus $3 per gigabyte.

So, if we define x as the number of gigabytes that Violet uses, then the monthly cost is given by:

C(x)=  $38 + x*$3

And she wants to spend less than $80 per month, so we can write the inequality:

$38 + $3*x < $80

Solving that for x we get:

$3*x < $80 - $38 = $42

x < $42/$3

x < 14

If Javier paid $92 for 5 notebooks and 3 pencils and Laura paid $56 for 2 notebooks and 6 pencils, then the price of each notebook is $16 and that of each pencil is $4, calculated using linear equations.

As per question statement, Javier paid $92 for 5 notebooks and 3 pencils while Laura paid $56 for 2 notebooks and 6 pencils.

We are required to calculate the price of each notebook and each pencil.

To solve this question, let us assume that the price of each notebook is  "x" and that of each pencil is "y". Now, we will form two linear equations, each with the two assumed variables, based on the conditions mentioned in the question statement, and solving the equations, we will obtain our desired answer.

Since Javier bought 5 notebooks and 3 pencils for $92 and the price of each notebook is assumed to be "x" and that of each pencil is assumed to be "y", we can write that

[tex][(5x+3y)=92]...(1)\\or,5x = 92-3y\\or,x=\frac{(92-3y)}{5}...(2)[/tex]

And in Laura's case, she bought 2 notebooks and 6 pencils for $56, i.e.,

[tex][(2x+6y)=56]...(3)\\or, 2(x+3y)=56\\or, (x+3y)=\frac{56}{2}\\ or,(x+3y)=28\\or,x=(28-3y)...(4)[/tex]

Now, equating (2) and (4), we get,

[tex]x=\frac{(92-3y)}{5}=(28-3y)\\ or, \frac{(92-3y)}{5}=(28-3y)\\ or, (92-3y)=5(28-3y)\\or, 92-3y=140-15y\\or,(15y-3y)=140-92\\or,12y=48\\or,y=\frac{48}{12}=4[/tex]i.e., Price of each pencil is $4.

Now, using (y = 4) in the equation (4), we get,

[tex]x=[28-(3*4)]\\or,x=(28-12)\\or,x=16[/tex]i.e., Price of each notebook is $16.

Hence, the correct answer is

option(C) $16 for a notebook and $4 for a pencil.

Answer: The diagram shows a rectangle.

Step-by-step explanation:

A rectangle Expression for "a": a = 12b - 30,Expression for "b": b = (12b² - 30b) / (12b - 30),Length of the rectangle: Length = a = 12b - 30,Perimeter of the rectangle: Perimeter = 2 × (13b - 30)

Let's break down the given information step by step:

The area of the rectangle is given as 12b² - 30b.

The expression for "a":

The area of a rectangle is equal to its length (a) multiplied by its width (b). So, set up the following equation:

Area = Length ×Width

12b² - 30b = a × b

To find the expression for "a," divide both sides of the equation by "b":

a = (12b² - 30b) / b

Simplify the expression for "a":

a = 12b - 30

The expression for "b":

From the same equation as above,  that:

Area = Length × Width

12b² - 30b = a × b

To find the expression for "b," divide both sides of the equation by "a":

b = (12b² - 30b) / a

Substitute the value of "a" from the previous expression:

b = (12b² - 30b) / (12b - 30)

The length of the rectangle:

The length of the rectangle is represented by "a," so the expression for the length is: a = 12b - 30

The perimeter of the rectangle:

The perimeter of a rectangle is given by the formula: Perimeter = 2 ×(Length + Width)

Since the rectangle has two pairs of equal sides (opposite sides are equal in a rectangle), the expression for the perimeter will be:

Perimeter = 2 × (a + b)

Substitute the value of "a" from the expression we found earlier:

Perimeter = 2 × ((12b - 30) + b)

Simplify the expression for the perimeter:

Perimeter = 2 ×(13b - 30)

If A,B, and C are the letters selected and we use A twice, B twice, and C once. The number of ways different passwords exist in this scenario are 30.

A password, sometimes known as a passcode (in devices made by Apple, for instance), is a hidden piece of information that is typically a long string of characters and is used to verify a user's identity. Passwords were always thought to be memorized, but today's average person has access to a huge number of password-protected services, making it difficult to remember a different password for each one. The secret is kept by a party known as the claimant, and the person confirming the claimant's identity is known as the verifier, according to the nomenclature of the NIST Digital Identity Guidelines. The verifier can determine the identity of the claimant when the claimant successfully uses a recognized authentication technique to show the verifier that they know the password.
