If the markup is 5% of the dealer's cost then the dealer's cost of the refrigerator is $690.

Markup can be calculated using the formula.

Markup= (Selling price - Cost )/Cost

In the given question

The selling Price = $724.50

markup = 5% = 0.05

let the dealer's cost be "x".

Substituting the values in the dealer's formula we get

Markup= (Selling price - Cost )/Cost

0.05=(724.50-x)/x

0.05x=724.50-x

x+0.05x=724.50

Solving further we get

1.05x=724.50

x=724.50/1.05

x=690

Therefore , the dealer's cost of the refrigerator is $690.

Answer:

2 (3 + 6x), 3 (2 + 4x) and 6 (1 + 2x)

Step-by-step explanation:

Given the expression 6 + 12x.

The following functions are equivalent;

Factoring out common number;

For 2;

2(3) + 2(6x)

2 (3 + 6x)

Factoring out 3;

3(2) + 3(4x)

3 (2 + 4x)

Factoring out 6;

6(1) + 6(2x)

6 (1 + 2x)

Hence the possible equivalent expressions are 2 (3 + 6x), 3 (2 + 4x) and 6 (1 + 2x)

the input value is x because when you use the equation you need x to get y.

Given:

[tex](3x-2)^9[/tex]

To find:

The coefficient of [tex]x^6[/tex] in the expansion of [tex](3x-2)^9[/tex].

Solution:

We know that, in the expansion of [tex](x+y)^n[/tex],

[tex]T_{r+1}=^nC_rx^{n-r}y^r[/tex]       ...(i)

[tex](3x-2)^9[/tex] has only one x and in [tex]x^6[/tex], the power of x is 6. It is possible if

[tex]n-r=6[/tex]

[tex]9-r=6[/tex]

[tex]9-6=r[/tex]

[tex]3=r[/tex]

Putting n=9, r=3, x=3x and y=-2 in (i), we get

[tex]T_{3+1}=^9C_3(3x)^{9-3}(-2)^3[/tex]

[tex]T_{4}=\dfrac{9!}{3!(9-3)!}\times (3x)^{6}(-8)[/tex]

[tex]T_{4}=\dfrac{9\times 8\times 7\times 6!}{3\times 2\times 1\times (9-3)!}\times (729x^{6})(-8)[/tex]

[tex]T_{4}=84\times (729)\times (-8)\times x^{6}[/tex]

[tex]T_{4}=-489888x^6[/tex]

Therefore, the coefficient of [tex]x^6[/tex] in the expansion of [tex](3x-2)^9[/tex] is -489888.

Answer:

Monthly charges = $70

Intuition charges = $2710

Step-by-step explanation:

There is intuition fee and per month fee for joining the Pine River country club.

Total cost for 7 months is $3200

Total cost for one and a half years is $3970

one and a half years means 18 months.

To find:

Intuition fee and monthly dues?

Solution:

Let the intuition fee = [tex]i[/tex]

Let the monthly dues = [tex]m[/tex]

Total cost for 7 months can be represented as

[tex]i+7m = 3200[/tex] ..... (1)

Total cost for 18 months can be represented as

[tex]i+18m = 3970 .... (2)[/tex]

Here, we have 2 equations and 2 variables whose values are to be found.

Let us use elimination method to solve the equations.

Subtracting equation (1) from (2):

[tex]11m = 770\\\Rightarrow m = 70[/tex]

Therefore, the monthly dues are $70.

Using equation (1), we can find the value of [tex]i[/tex].

[tex]i + 70\times 7 = 3200\\\Rightarrow i = 3200 - 490\\\Rightarrow i = \$2710[/tex]

Therefore, intuition charges are $2710.

Step-by-step explanation:

the missing functions in the piecewise function are f(x) = - x - 4 for - 6 ≤ x ≤ - 1, f(x) = 4 for 1 < x ≤ 2 and f(x) = - 1 / 2 x - 6 for 2 < x ≤6.

We are given the graph of a piecewise function.

We need to complete the function to represent the graph completely.

We know that, a piecewise function is a function that has different functions for a particular set of values for x.

Here, we can see that:

For the values of x in between - 6 and - 1 that is - 6 ≤ x ≤ - 1, we get the function as:

f(x) = - x - 4

For the values of x in between - 1 and 2 that is - 1 < x ≤ 2, we get the function as:

f(x) = 4

For the values of x in between 2 and 6 that is 2 < x ≤6, we get the function as:

f(x) = - 1 / 2 x - 6

Therefore, we get that, the missing functions in the piecewise function are f(x) = - x - 4 for - 6 ≤ x ≤ - 1, f(x) = 4 for 1 < x ≤ 2 and f(x) = - 1 / 2 x - 6 for 2 < x ≤6.
