Answer:

The price per wind chime that will maximize revenue = $ 315

Step-by-step explanation:

Given - A gift shop sells 160 wind chimes per month at $150 each. the owners estimate that for each $15 increase in price, they will sell 5 fewer wind chimes per month.

To find - Find the price per wind chime that will maximize revenue.

Proof -

Given that,

Total Wind chimes selling = 160

Price of each Wind chime = $150

Now,

Given that, for each $15 increase in price, they will sell 5 fewer wind chimes per month.

So,

Let the price = 150 + 15x

So,

Number of wind Chimes sold per month = 160 - 5x

So,

Total Revenue, R = (150 + 15x)(160 - 5x)

                             = 24000 - 750x + 2400x - 75x²

                             = 24000 + 1650x - 75x²

⇒R(x) = 24000 + 1650x - 75x²

Differentiate R with respect to x , we get

R'(x) = 1650 - 150x

Now,

For Maximize Revenue, Put R'(x) = 0

⇒1650 - 150x = 0

⇒150x = 1650

⇒x = 1650/150

⇒x = 11

∴ we get

Price per Wind chime = $ 150 + 15(11)

                                    = $ 150 + 165

                                    = $ 315

So,

The price per wind chime that will maximize revenue = $ 315

Answer:

Range → {7, 9, 0}

Step-by-step explanation:

Range of a function is a set of y-values or output values of the function.

Similarly, Domain of a function is the set of x-values or input values of the function.

Given points in the graph are (0, 7), (3, 9) and (9.4, 0)

Therefore, set of y-values {7, 9, 0) will be the Range.

Range of the function → {7, 9, 0}

Answer:

Region D

Step-by-step explanation:

Let's start with the easy one, x is greater than or equal to 3. We can find that line on the graph pretty easily (x = 3). Since x has to be greater than 3, we can narrow our choices down to either B or D.

Now the next inequality. How about we put it in slope intercept form so we can understand it better? Simplifying, we get

y is less than or equal to 1/3x - 1

We know this line is the other line on the graph, and since y has to be less than that line, we know that that inequality narrows it down to either C or D.

Since D appears in both inequalities, we now know the answer is D.

Answer: Draw a dot, then draw a line from that dot, then at the end of the line draw a arrow. Label the dot L, and put another dot in the center of the line and label it M.

Answer:

θ ≈ 17.1°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan θ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{4}{13}[/tex] , then

θ = [tex]tan^{-1}[/tex] ([tex]\frac{4}{13}[/tex] ) ≈ 17.1° ( to the nearest tenth )

Answer:

Step-by-step explanation:

You use the stem as the first number and leaves as second so ppl who live less than 40 miles live one of them lives 21 miles away another lives 22,23,27,28,29,30,31,34 and the others live more than that starting by ppl who live 47 miles away so if you count 21,22,23,27,28,29,30,31,34 you'll come up with 9 of them who live less then 40 miles away from work

hopefully you got it

Answer:

[tex]M = 4.67[/tex]

Step-by-step explanation:

Given

[tex]Data: 3, 7, 8, 12, 16, 18[/tex]

Required

The mean absolute deviation

Start by calculating the mean

[tex]\bar x = \frac{\sum x}{n}[/tex]

[tex]\bar x = \frac{3+ 7+ 8+ 12+ 16+ 18}{6}[/tex]

[tex]\bar x = \frac{64}{6}[/tex]

[tex]\bar x = 10.67[/tex]

The mean absolute deviation is then calculated using:

[tex]M = \frac{1}{n}\sum\limits^n_{i=1}|x _i - \bar x|[/tex]

So, we have:

[tex]M = \frac{1}{6}(|3 - 10.67| +|7 - 10.67| + |8 - 10.67| + |12 - 10.67| + |16 - 10.67| + |18 - 10.67|)[/tex]

[tex]M = \frac{1}{6}(|-7.67| +|- 3.67| + |-2.67| + |1.33| + |5.33| + |7.33|)[/tex]

Remove absolute brackets

[tex]M = \frac{1}{6}(7.67 +3.67 + 2.67 + 1.33 + 5.33 + 7.33)[/tex]

[tex]M = \frac{1}{6}*28[/tex]

[tex]M = 4.67[/tex]

Answer:

{-2, 0, 4}

Step-by-step explanation:

Domain is defined as all the inputs possible to a function.

On a graph, you may know this as the value of x.

This means the domain is equal to all values of x that produce an output.

The only values of x that have a point on them is x = 4, x = 0, and x = -2, all of which have points on the x-value.

Answer:

10 2/3 cars

Step-by-step explanation:

We can use a ratio

4 cars            x cars

------------- = -----------

3 hours          8 hours

Using cross products

4 *8 = 3 *x

32 = 3x

Divide each side by 3

32/3 = 3x/3

The measure of angle ADC in quadrilateral ABCD is; 115°

From the given quadrilateral ABCD, we see that ∠A = 115°

Now, we see that AB is congruent to CD and also AD is congruent to BC.

Since, we have such congruency it means that ∠A = ∠D.

Thus, ∠ADC = 115°

In conclusion, we can say that ∠ADC is 115°

Answer:

20 years

Step-by-step explanation:

9000/ 100= 900 = 10%

900/2= 450

450 x 2= 900

900 x 10= 9000

Now we multiply 10 by 2 because we doubled the value of our 450 into a 900 and now we get 20.

Compound interest is the interest that is made from the principal and the interest as well in consecutive years.

The number of years it will take to double the investment is 15 years.

Compound interest is the interest that is made from the principal and the interest as well in consecutive years.

We have,

Principal = $9000

Rate = 5%

The formula is given as:

A = p [tex](1 + \frac{R}{100} )^{n}[/tex]

n = number of years

Double the investment:

Amount = 2 x 9000 = 18000

Now,

18000 = 9000 [tex](1 + \frac{R}{100} )^{n}[/tex]

2 = [tex](1 + 0.05)^{n}[/tex]

2 = [tex]1.05^{n}[/tex]

Taking log on both sides.

[ log a² = 2 log a ]

log 2 = n log 1.05

0.30 = n 0.02

n = 0.30 / 0.02

n = 15

Thus,

The number of years it will take to double the investment is 15 years.
