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.

Answer:

The answer is 82 degrees.

Volume = PI x r^2 x h

r -s 1/2 the diameter ( 20/2 = 10)

Volume = 3.14 x 10^2 x 5

Volume = 3.14 x 100 x 5

Volume = 3.14 x 500

Volume = 1570 cubic meters

The answer is 1570.8

Add all of the sides together. 2x+1 plus 2x+1 equalls 4x +2

Then add that to (xsquared+3x-2 + xsquared+3x-2) which is 2xsquared +6x-4+4x+2 which equalls D

Just add the distance that each is from the origin.

(-16, -16) is 16 away from 0, 0

(8, -16) is 8 away from origin

16 + 8 = 24

This only works because these two points` x-axis coordinates match. It doesn`t work with everything.

Answer:

Yeah

Step-by-step explanation:

Considering that XZ is the perpendicular bisector of segment WY, we have that the value of k is of k = 6.

It means that XZ divides the segment into two segments of equal length, given by:

WX = XY.

From the lengths given, we can solve for k as follows:

3k + 17 = 7k - 7

4k = 24.

k = 24/4

k = 6.

The value of k is of k = 6.

Answer:

x = 25

Step-by-step explanation:

Let's start with the sentence

Seven less than twice a number is 43.

Let's rearrange it to make it easier to convert to an equation

Twice a number subtracted by seven is 43

Now let's convert to an equation

Twice a number: 2x

Subtracted: -

Seven: 7

is: =

43

2x - 7 = 43

Now we can simplify by adding 7 to both sides.

2x = 50

Lastly, let's divide by 2 to isolate the x variable.

x = 25

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)

Answer:

Answer is "B"

Step-by-step explanation:

Rearrange terms:  7-2x=9x+19

-2x+7=9x+19

 Subtract 7 from both sides of the equation: -2x+7=9x+19

-2x+7-7=9x+19-7

Simplify: -2x=9x+12

Subtract 9x from both sides: -2x=9x+12

-2x-9x=9x+12-9x

simplifiy: -11x=12

solution: x=-12/11

Answer:

16....................

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.

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.

[tex]\textsf {Domain} : -\infty \: < x < \infty \\\textsf {In interval notation: } (-\infty, \infty)}[/tex]

[tex]\textsf {Range: } f\left(x\right)\le \:2 \\\textsf {In interval notation:} \:(-\infty \:,\:2][/tex]

Step-by-step explanation:

There are no undefined points for the function. So the domain is the set of all x values

The domain of x is (-∞, ∞) so x can be negative or positive. However, |x| is always positive

So if the inequality |x| + y ≥ 2 is to hold good then y has to be less than equal to 2, otherwise the left side drops below 2 and the inequality is not satisfied.

So the range is the set of all values in the interval (-∞, 2)
