Step-by-step explanation:

The series in sigma notation is:  representing terms increasing by 4 starting from -5.

To represent the series in sigma notation, let's first examine the pattern of the terms.

The given series starts with -5 and each subsequent term increases by 4. We can express this pattern using the formula:

[tex]\[ a_n = -5 + (n - 1) \times 4 \][/tex]

Here, [tex]\( a_n \) represents the \( n \)th term of the series[/tex].

Now, let's break down the components of the formula:

-[tex]\( -5 \) is the initial term of the series.- \( (n - 1) \) accounts for the position of each term in the series. When \( n = 1 \), \( (n - 1) = 0 \), so the first term is \( -5 \). As \( n \) increases, \( (n - 1) \) increases by 1, causing the series to increase by 4 each time.- \( 4 \) is the common difference between consecutive terms in the series.[/tex]

Next, we represent the series using sigma notation:

[tex]\[ \sum_{n=1}^{5} (-5 + (n-1) \times 4) \][/tex]

This notation indicates that we sum up the expression [tex]\( -5 + (n-1) \times 4 \) for \( n \)[/tex] ranging from 1 to 5, which covers all the terms of the given series.

In summary, the series is represented in sigma notation as described above, capturing the pattern of increasing terms starting from -5.

On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.

y = 1.125x is the equation to show the relationship between the number of euros and the value in dollars.

Given that On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars

Let "y" be the value in dollars

Let "x" be the number of euros

We have to write a equation in form of y = kx

8 euros were worth 9 dollars

"k" is found as follows:

[tex]k = \frac{\text{value in dollars}}{\text{number of dollars}}[/tex]

[tex]k = \frac{9}{8}[/tex]

Therefore, equation of y = kx is given as:

[tex]y = \frac{9}{8}x[/tex]

[tex]y = 1.125x[/tex]

To check the equation, use the another given value

24 euros were worth $27

[tex]y = 1.125 \times 24\\\\y = 27[/tex]

Hence the equation y = 1.125x is correct    

Answer:

Problem Recognition Stage (the first stage)

Explanation:

The "Consumer Buying Decision Process" consists of 5 stages. These are: Problem Recognition, Information Search, Evaluation of Alternatives, Purchase Decision and Post-Purchase Evaluation. This information is commonly used by marketing businesses in order to know the habit or behavior of people upon buying goods and services.

Olivia's situation above is in the "Problem Recognition" stage. This is the first stage of the process. She realizes that she needs the winter boots because of the cool weather and thus, she realizes that she has a need or a problem that she wanted to solve. Buyers recognize this problem as a gap in their needs, thus they want to fill it immediately once they recognize it. This will be followed by "Information Search," a time whereby she'll consider some options in buying boots.

Thus, this explains the answer.

The correct statement is that the terms are

A. The next three numbers are 1/8, 1/32, and 1/128.

B. The next three-term will be 9, 13.5, and 20.5.

A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after. A series is a sum of sequence terms. That is, it is a list of numbers with adding operations between them.

Given

A. 32, 8, 2, 1/2, ...

B. 16/9, 8/3, 4, 6, ...

A.  32, 8, 2, 1/2... can be expressed as [tex]2^{2n - 1}[/tex]

Then For n= -1, -2, and -3, Then the next three numbers will be

[tex]2^{-2 - 1} \ \ \ \ \ , \ 2^{-4 - 1} \ \ \ \ \ , \ 2^{-6 - 1}\\\dfrac{1}{8} \ \ \ \ \ \ \ \ \ \ \ , \dfrac{1}{32} \ \ \ \ \ \ \ \ \ \ , \dfrac{1}{128}[/tex]

The next three numbers are 1/8, 1/32, and 1/128.

B.  16/9, 8/3, 4, 6... each term increases by 2/4. So the next three-term will be 9, 13.5, and 20.5.

Thus, the terms are 9, 13.5, and 20.5.

The relationship between the distance traveled by a car and the amount of gas in the car is inverse. As the distance increases, the gas decreases

The relationship between the distance traveled by a car and the amount of gas in the car is inverse. This means that as one quantity increases, the other decreases. In this case, as the distance traveled by a car increases, the amount of gas in the car decreases, because the car uses gas to move. In other words, the more you drive, the less gas you have left in your car.

The value of b in the equation [tex]\( 3.2 = \frac{4}{5}(b - 5) \)[/tex] is 9.

To solve for b in the equation [tex]\(3.2 = \frac{4}{5}(b - 5)\)[/tex], we'll first distribute [tex]\(\frac{4}{5}\)[/tex] across b - 5:

[tex]\[3.2 = \frac{4}{5}b - \frac{4}{5} \times 5\]\[3.2 = \frac{4}{5}b - 4\][/tex]

Next, let's isolate the term containing b by adding 4 to both sides:

[tex]\[3.2 + 4 = \frac{4}{5}b\]\[7.2 = \frac{4}{5}b\][/tex]

Now, to solve for b, we'll multiply both sides by [tex]\(\frac{5}{4}\)[/tex] to isolate b:

[tex]\[b = 7.2 \times \frac{5}{4}\]\[b = 9\][/tex]

So, the value of b is 9.

40%

The formula is

Old-new/old *100

115-69/115*100

The percentage decrease is 40% if the price of an item yesterday was 115. Today the price fell to 69.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

The price of an item yesterday was 115. Today the price fell to 69.

The difference in price = 115 - 69 = 46

Percentage decrease = (46/115)×100 = 40%

Thus, the percentage decrease is 40% if the price of an item yesterday was 115. Today the price fell to 69.

The ordered pair (-3, 1) is not a solution to system because it makes at least one of the equations false

Solution:

Given system of equations are:

x - 4y = 6 ------- eqn 1

3x + y = -8 ------------ eqn 2

Given ordered pair is (-3, 1)

We have to check if the options are true

Let us substitute (x, y) = (-3, 1) in eqn 1

[tex]-3 - 4(1) = 6\\\\-3 - 4 = 6\\\\-7\neq 6[/tex]

Thus the given ordered pair (-3, 1) did not satisfy the first equation

Substitute (x, y) = (-3, 1) in eqn 2

[tex]3(-3) + 1 = -8\\\\-9 + 1 = -8\\\\-8 = -8[/tex]

Thus the given ordered pair (-3, 1) satisfied the second equation

But for a ordered pair to be a solution to system of equations, it must satisfy both the equations

Thus the ordered pair (-3, 1) is not a solution to system because it makes at least one of the equations false

Answer:

f ( 4 ) = 18

Step-by-step explanation:

Explanation:

f ( x ) = 5 x − 2

Replace  4  instead of  x  to find  f ( 4 )

f ( 4 ) = 5 ( 4 ) − 2 = 20 − 2 = 18

The value of f(-4) for the function f(x) = x^2 - 5x + 2 is 38.

To find the value of f(-4) for the function f(x) = x^2 - 5x + 2, you substitute -4 for x in the function.

It looks like this:

f(-4) = (-4)^2 - 5(-4) + 2

First, you square -4, which is (-4)^2 = 16.

Then, you calculate -5 times -4, which is 20.

Finally, you add 2 to the result.

So, f(-4) is equal to:

f(-4) = 16 - 20 + 2 = 38

The final answer is 38.

Step-by-step explanation:

The point-slope form of an equation of a line:

[tex]y-y_1=m(x-x_1)[/tex]

m - slope

(x₁, y₁) - point on a line

The formula of a slope:

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have the points (9, -2) and (4, 2).

Substitute:

[tex]m=\dfrac{2-(-2)}{4-9}=\dfrac{2+2}{-5}=-\dfrac{4}{5}[/tex]

Put the value of a slope and coordinates of first or second point to the equation of a line:

[tex](9,\ -2),\ m=-\dfrac{4}{5}\\\\y-(-2)=-\dfrac{4}{5}(x-9)\\\\\boxed{y+2=-\dfrac{4}{5}(x-9)}\\\\(4,\ 2),\ m=-\dfrac{4}{5}\\\\y-2=-\dfrac{4}{5}(x-4)}[/tex]

To evaluate the expression 24/b+8 for b=9, substitute 9 for b to get 24/9 + 8, which simplifies to approximately 10.67.

To evaluate the expression 24/b+8 when b=9, we substitute the value of b into the expression and perform the arithmetic operation.

First, we replace b with 9:

24/9 + 8

Then, we divide 24 by 9:

2.666... + 8

Next, we add 8 to the quotient:

2.666... + 8 = 10.666...

The result of evaluating the expression 24/b+8 for b=9 is approximately 10.67.

To solve the given equation to find the solution set :

Multiply the equation (1) into 2 we get

[tex]6x+6y=-36\hfill (3)[/tex]

Multiply the equation (2) into 3 we get

[tex]-6x+6y=-12\hfill (4)[/tex]

Now adding the equations (3) and (4) we get

[tex]6x+6y=-36[/tex]

[tex]-6x+6y=-12[/tex]

[tex]12y=-48[/tex]

[tex]y=\frac{-48}{12}[/tex]

Therefore y=-4

Substitute the value of y=-4 in the equation (1) we get

[tex]3x+3y=-18[/tex]

[tex]3x+3(-4)=-18[/tex]

3x-12=-18

3x-12+12=-18+12

3x=-6
