what is the domain of the function?
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.

an initial investment of $9000 grows at an annual interest rate of 5% compounded continuously. how long will it take to double the investment?
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.
What is compound interest?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.

What is the mean absolute deviation of the data: 3, 7, 8, 12, 16, 18 of each number. I tried to take a picture but it is too blurry. But pls hurry hurry!!!
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]

Which region represents the solution to the given system of inequalities?
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.

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. find the price per wind chime that will maximize revenue.
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

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

Morris climbs up a fruit tree and tosses a pear to his brother. The graph shows the height of the pear as a function of x, the distance of the pear from the tree. What is the range for this situation?
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}
