Answer:

The markup percentage is 61.2

Step-by-step explanation:

Given as :

The cost price of each ornaments = $23

The sell price of each ornament = $37.08

Let The markup percentage = x

Now, According to question

Markup percentage = [tex]\dfrac{s.p - c.p}{c.p}[/tex] × 100

Or, x% = [tex]\dfrac{37.08 - 23}{23}[/tex]

Or, x% = [tex]\dfrac{14.08}{23}[/tex]

Or, x% = 0.612

∴ x = 0.612 × 100

I.e x = 61.2

So, The The markup percentage = x = 61.2

Hence, The markup percentage is 61.2 Answer

Answer:

2x^2-16x+34

Step-by-step explanation:

Since Y is equal to -5

And  you substitute -5 in the equation.

You now have -5=2x^2-16x+29

Add 5 to both sides

5-5=2x^-16x+29+5

The solution of the system of equations will be given as x = 4 ± i.

The solution of the equation means the value of the unknown or variable.

The equations are given below.

y = – 5                      ....1

y = 2x² – 16x + 29    ....2

From equation 1 and 2, we have

2x² – 16x + 29 = –5

2x² – 16x + 34 = 0

x² – 8x + 17 = 0

Then the value of x will be

Answer:

f(x) = (2x + 1)(2x − 1)

Explanation:

As we can see from the above function f(x) = 4[tex]x^{2}[/tex] − 1, we need to find x-intercept, i.e., the value of x where this function's value is zero.

So let us Equate the function with zero

4[tex]x^{2}[/tex] - 1 = 0 => 4[tex]x^{2}[/tex] = 1 => [tex]x^{2}[/tex] = 1/4 => x = [tex]\sqrt{1/4}[/tex]

Hence we get 2 values of x, i.e., +1/2, and -1/2.

So now we need to check out the functions which are zero at this values of x, so let us substitute values of x in each and every option and see the values of functions.

Option A - f(x) = (4x + 1)(4x − 1) = 3, -3

Option B - f(x) = (2x + 1)(2x − 1)  = 0

Option C - f(x) = 4(x2 + 1)  = 5

Option D - f(x) = 2(x2 − 1) = -3/2

Hence answer is Option B

Note: As you missed to mention the graph for f(x) = x + 1 from where we had to check which option defines the accurate graph. But, after a little research, I was able to get the graph of this question, and hence attaching the graph. So, I am answering based on that graph which, anyways, would clear your concept about determining the domain of the function that shows in a graph.

Answer:

x > 1 is the domain of the f(x) = x + 1.

Step-by-step explanation:

A domain is the set of all x values that a function passes through. It means a domain is set of all input values where the function is defined, meaning whatever you input the x value, for every x-value there is only one y-value that corresponds to it.

So, now lets talk about the given function f(x) = x + 1 and its graph as shown in attached figure. Carefully observe the top right part of the graph of f(x) = x + 1. It is validating the condition of x > 1.

For example,

Just input some x values, greater than 1 i.e. x > 1, in f(x) = x + 1 to determine the output values.

For example, for x > 1

and so on.

So, the top right part of the graph of f(x) = x + 1 is validating the condition of x > 1 as it is passing through P(2, 3), P(3, 4) and P(4, 5) etc. and so on.

So, x > 1 is the domain of the f(x) = x + 1.

HOPE THIS HELPS!!!

Answer:

x = -5

Step-by-step explanation:

let the number be x

"five times a number" : 5x

"Six more than five times a number" : 5x + 6

"twice the number" = 2x

"Six more than five times a number = 2x - 9

"Six more than five times a number" = "Six more than five times a number

5x + 6 = 2x - 9

5x - 2x = -9 -6

3x = -15

x = -15 / 3

x = -5

To find the coordinates of the other endpoint B given the midpoint M and one endpoint A. Apply the midpoint formula and solve the equations to find the coordinates of B(-1, 5).

The midpoint coordinates are given as M(3, -2) and one endpoint is given as A(7, -9). To find the coordinates of the other endpoint, we can use the midpoint formula which states that the coordinates of the midpoint are the average of the coordinates of the two endpoints.

Let the coordinates of the other endpoint be B(x, y). Using the midpoint formula, we have:

[(x + 7) / 2, (y + -9) / 2] = (3, -2)

Simplifying the equation, we get:

(x + 7) / 2 = 3

(y - 9) / 2 = -2

Multiplying both sides by 2, we have:

x + 7 = 6

y - 9 = -4

Subtracting 7 from both sides, we get:

x = -1

Subtracting -9 from both sides, we get:

y = 5

Therefore, the coordinates of the other endpoint are B(-1, 5).

Answer:

A) The increase population of town after 3 years is 1.2 times initial population

B) The increase population of town after 5 years is 1.4 times initial population .

Step-by-step explanation:

Given as :

The rate of growth of population of a town = r = 7.5%

Let The initial population of town = p

A ) Let The increase population of town after 3 years = P

The time period = n = 3 years

Now, According to question

The increase population of town after n years = initial population of town × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

Or, The increase population of town after n years = initial population of town × [tex](1+\dfrac{\textrm r}{100})^{\textrm n}[/tex]

Or, The increase population of town after 3 years  = p × [tex](1+\dfrac{\textrm 7.5}{100})^{\textrm 3}[/tex]

Or, P = p × [tex](1.075)^{3}[/tex]

Or, P = p × 1.242

So, The increase population of town after 3 years = P = 1.2 times initial population

Hence,The increase population of town after 3 years is 1.2 times initial population .  Answer

B )  Let The increase population of town after 5 years = P'

The time period = n = 5 years

Now, According to question

The increase population of town after n years = initial population of town × [tex](1+\dfrac{\textrm rate}{100})^{\textrm time}[/tex]

Or, The increase population of town after n years = initial population of town × [tex](1+\dfrac{\textrm r}{100})^{\textrm n}[/tex]

Or,  The increase population of town after 5 years = p × [tex](1+\dfrac{\textrm 7.5}{100})^{\textrm 5}[/tex]

Or, P' = p × [tex](1.075)^{5}[/tex]

Or, P' = p × 1.4356

So, The increase population of town after 5 years = P' = 1.4 times initial population

Hence,The increase population of town after 5 years is 1.4 times initial population . Answer

Answer:

x²-9x+12 = (x - (9/2))²- (33/4)

Step-by-step explanation:

Look at the photo below for the details.

:)

In order to find the variables p and q in the equation x^2 - 9x + 12 = (x-p)^2 - q, we first complete the square on the left-hand side which leads us to determine that p=4.5 and q=32.25.

The original equation given is x^2 - 9x + 12 = (x-p)^2 - q. To find the values of p and q, we need to rewrite the left-hand side of the equation in the format of (x-p)^2. This can be done through a process known as completing the square. Looking at the equation x^2 - 9x + 12, we have a perfect square x^2 - 9x + (9/2)^2 = (x-4.5)^2. However, remember, we added (9/2)^2 to both sides, so we have (x-4.5)^2 = x^2 - 9x + 12 + 20.25. Simplifying, (x-4.5)^2 = x^2 - 9x + 32.25, which is our original equation format. Thus, p=4.5 and q=32.25.

Each computer costs $225 and each printer costs $150

Step-by-step explanation:

Thomas is starting a new company. He has two quotes from a computer company for the cost of computers and printers

We need to find how much each computer and printer costs

Assume that the cost of each computer is $x and the cost of each printer is $y

∵ The cost of each computer is $x

∵ The cost of each printer is $y

∵ The cost of 3 computers and one printer is $825

- Multiply x by 3 and add the product to y, equate the sum by 825

∴ 3x + y = 825 ⇒ (1)

∵ The cost of 4 computers and 2 printers is $1200

- Add the product of 4, x and the product of 2 , y and equate the

  sum by 1200

∴ 4x + 2y = 1200 ⇒ (2)

Now we have a system of equations to solve it

Multiply equation (1) by -2 to eliminate y

∵ -6x - 2y = -1650 ⇒ (3)

- Add equations (2) and (3)

∴ -2x = -450

- Divide both sides by -2

∴ x = 225

Substitute the value of x in equation (1) to find y

∵ 3(225) + y = 825

∴ 675 + y = 825

- Subtract 675 from both sides

∴ y = 150

Each computer costs $225 and each printer costs $150

By setting up a system of equations from the scenarios provided, we can determine that each computer costs $225 and each printer costs $150.

To determine the cost of each computer and printer, we can set up a system of equations based on the information provided. Let C represent the cost of one computer and P represent the cost of one printer. Using the first scenario where three computers and one printer cost $825, we can write the first equation as:

3C + P = $825 ... (1)

For the second scenario where four computers and two printers cost $1200, we can write the second equation as:

4C + 2P = $1200 ... (2)

Next, we'll solve this system of equations using either substitution or elimination method. To use elimination, we can multiply equation (1) by 2 to eliminate the printers:

6C + 2P = $1650 ... (3)

Now, we subtract equation (2) from equation (3) to find C:

6C + 2P - (4C + 2P) = $1650 - $1200

2C = $450

C = $225

We now know each computer costs $225. To find the cost of a printer, we can replace C in either equation (1) or (2). Let's use equation (1):

3(225) + P = $825

675 + P = $825

P = $825 - 675

P = $150

Thus, each computer costs $225 and each printer costs $150.
