Recycled​ CDs, Incorporated, offers a choice of 5 used CDs for ​$29​, with each additional CD costing ​$. Write a cost function for purchasing 5 or more CDs. What will the cost of buying CDs​ be? Let x represent the number of CDs over 5.

The inequality that can be used to determine the maximum number of outfit she can purchase is 55.17oo  ≤ 117.47.

The first step is to determine which inequality sign would be used.

The following are inequality signs and what they mean:

> means greater than

< means less than

≥ means greater than or equal to

≤ less than or equal to

The sign that would be used is the less than or equal to sign- ≤  . This is because Audrey cannot spend more than her budget.

The next step is to determine the total cost of items bought:

Total cost = $295.33 + (17.86 x 3) + 33.62 = $382.53

Now determine the amount of money she has left : $500 -  $382.53 = $117.47

(Total amount spent on outfit) amount left

(oo x $55.17)  ≤ 117.47

55.17oo  ≤ 117.47

This sequence follows the rules of Arithmetic Progression

Arithmetic Progression is an example of mathematical sequences. In this sequence, the next term is generated by adding the previous term to a fixed number which is called 'Common Difference'. This is generally represented by 'd'. It is calculated by subtracting any two consecutive terms in the sequence.

We can generally find out any term of the given statement. The  [tex]n^{th}[/tex] term of a sequence is calculated by adding the previous term to the common difference. The formula to calculate the [tex]n^{th}[/tex] term of an Arithmetic Progression is :

                     =>  [tex]a_{n} = a_{n-1} + d[/tex]

Here, n = No. of term, [tex]a_{n-1}[/tex] = previous term, and d = common difference

In the given sequence, 5,22,39,56......

Each term is separated by a common difference 'd'

Calculating d = a2-a1   => d = 22-5 => d = 17

Every term has a common difference of 17 so this is an Arithmetic Sequence

The value of x so that the equation based on a and b has a solution is x = -7/5

  An equation is about two expressions, either arithmetic or algebraic, that are related with a "=" sign that indicates equality of expressions.

  Equations can be graphed, they are used to model many problems and theories.

     As we can see, we have the following equation:

(a + 2)b + 13 = 5x

  and we have the values of the coefficients a and b, and these are:

   We substitute these values in the equation:

(a + 2)b + 13 = 5x

(18 + 2)-1 + 13 = 5x We solve the equation

(20)-1 +13 = 5x

-20 + 13 = 5x

5x = -7

Answer:

Step-by-step explanation:

Answer:

a₁ = 15

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] [ 2a₁ + (n - 1)d ]

where a₁ is the first term and d the common difference

given S₁₄ = - 63 , then

[tex]\frac{14}{2}[/tex] [ 2a₁ + 13d ] = - 63

7(2a₁ + 13d) = - 63 ( divide both sides by 7 )

2a₁ + 13d = - 9 → (1)

the nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

given a₁₄ = - 24 , then

a₁ + 13d = - 24 → (2)

subtract (2) from (1) term by term to eliminate d

a₁ + 0 = - 9 - (- 24)

a₁ = - 9 + 24 = 15

We have to find the equation of line

So, we know that

               y = mx + c, ---------------(1)

From graph,

           c = 40 and

           m = slope (we have to find it)

We kwon the slope of any two point

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

Where,

        x₁ = 0 , and y₁ = 40

        x₂ = 0 , and y₂ = 40        

So,

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

      m = [tex]\frac{70-40}{15-0}[/tex]

      m = [tex]\frac{30}{15}[/tex]

      m = 2

When measuring height, it is necessary to represent both the vertical position and the separation between the minimum and maximum place or location. The height of Kara's building is 186.6 ft.

In math, height can be defined as the vertical distance from the top to the base of the object. Height is the distance between an object's highest and lowest points.

The measurement of an object's height from the base to the top is known as the height. It is sometimes referred to as altitude in geometry. The vertical distance between the lowest and highest point is measured. In coordinate geometry, it is often the measurement along the y-axis of an object.

Mount Everest's summit serves as an illustration of height.

Ignoring the height of Kara,

h = 50 tan 75°

substituting the value of tan 75°, we get

= 50 × 3.7321

Height of building = 186.6 ft.

Therefore, the approximate height of Kara's building is 186.6 ft.

In the given sequence, the next term is obtained by multiplying the next term by (-1), hence it is a geometric sequence with r = 1. The next two terms are 3, -3.

Arithmetic sequence.

In a arithmetic sequence, the next term = the previous term + common difference. Or mathematically:

a(n) = a(n-1) + d

or d = a(n) - a(n-1) for all n

Where d = common difference.

Geometric sequence.

In a geometric sequence,  the next term = the previous term x common ratio. Or mathematically:

a(n) = a(n-1) . r

or r = a(n)/a(n-1) for all n

Where r = common ratio

The sequence given:

           3,-3,3,-3, . . . . .

In this sequence:

a(1) = 3

a(2) = -3

a(3) = 3

a(4) = -3

The next two terms means a(5) and a(6). We already have a(4) = -3. Hence,

An equation is a mathematical statement with an equal symbol between two expressions that have equal values.

Given: If A-P-B and if AP=2x-9, AB=32, and PB=1.5x+6.

To find: Find PB.

According to the question,

AP + PB = AB

On putting the given values, we get,
