a new car that costs $22575 depreciates at a rate of 11% per year. The car's value can be modeled by the equation V(x)=22,575(0.89)x. evaluate the function over the domain (2,5,7) and interpet the results
Answer: The values of the function V(x) over the domain (2, 5, 7) are 17881.66, 12,606.01 and 9985.224.
Explanation:
The cost of car is $22575 and the value of car depreciate at a rate of 11% per year.
The value of car can be modeled by the equation,
[tex]V(x)=22,575(0.89)^x[/tex]
Where is number of years after purchase of car or the age of car. We have to find the value of the function over the domain (2,5,7), so put x=2,
[tex]V(x)=22,575(0.89)^2=17881.66[/tex]
It means the value of car will be $17881.66 after two years.
put x=5,
[tex]V(x)=22,575(0.89)^5=12,606.01[/tex]
It means the value of car will be $12,606.01 after five years.
put x=7,
[tex]V(x)=22,575(0.89)^7=9985.224[/tex]
It means the value of car will be $9985.224 after seven years.
Is x = -3 a solution to the equation -3X^2=-27

half the difference of a number and 7 is 11. what is the number?
1/2(x - 7) = 11
Distributive property.
0.5x - 3.5 = 11
Add 3.5 to both sides.
0.5x = 14.5
Multiply both sides by 2.
x = 29. (This is your answer.)
We can plug 29 into the original equation to verify.
1/2(x - 7) = 11
1/2(29 - 7) = 11
1/2(22) = 11
11 = 11 √ This is correct.

The image from rotating a figure in the first quadrant 180 degree clockwise.
When rotating a figure in the first quadrant 180 degrees clockwise, the x-coordinates and y-coordinates of the points are negated.
Explanation:When an object in the first quadrant is rotated 180 degrees clockwise, its position is reflected across both the x-axis and y-axis. This means that the x-coordinates are negated and the y-coordinates are also negated.
For example, if a point A is located at (3, 4) in the first quadrant, after rotating it 180 degrees clockwise, it will be reflected across the x-axis and y-axis to the position (-3, -4).
Therefore, all points in the figure will have their coordinates negated when rotated 180 degrees clockwise in the first quadrant.

A probability experiment consists of rolling a fair 6-sided die. Find the probability of the event below. Rolling a number greater than 2
Answer:
The numbers are 1, 2 ,3, 4, 5 and 6.
Therefore 4 of the 6 numbers are greater than 2 so the probability is 4 out of 6 or 2/3.
Step-by-step explanation:
The question relates to probability while rolling a six-sided die for a number greater than 2. There are four favorable outcomes; 3, 4, 5, or 6. Therefore, the probability of this event is 4/6 or 2/3.
Explanation:The question you asked pertains to the concept of probability, specifically within the context of a fair, six-sided die. In this experiment, there are 6 equally likely outcomes: 1, 2, 3, 4, 5, or 6. When asked for the probability of rolling a number greater than 2, the outcomes we consider favorable are 3, 4, 5, and 6. That's 4 favorable outcomes. So, to calculate the probability of this event, you must divide the number of favorable outcomes by the total number of possible outcomes. Thus, the probability of rolling a number greater than 2 on a six-sided die is 4/6 or reducing to its simplest form becomes 2/3.

−9x+2>18 OR 13x+15≤−4
Answer:
x < -19/13
Step-by-step explanation:
The solution to the inequalities −9x+2>18 and 13x+15≤−4 is to find values of x that satisfy either x < ∘⅗⁄3 or x ≤ ∘⅗/13.
Explanation:To solve the equations −9x+2>18 OR 13x+15≤−4, we need to treat them separately as two different inequalities.
For the first inequality, subtract 2 from both sides to get −9x > 16, then divide by −9 to isolate x, which gives us x < ∘⅓⁄9 or x < ∘⅗⁄3.
For the second inequality, subtract 15 from both sides to get 13x ≤ −4 − 15 or 13x ≤ −19. Finally, divide by 13 to isolate x, leading to x ≤ −⅓⁄13 or x ≤ ∘⅗/13.
Therefore, the solution to the system of inequalities is any x that satisfies at least one of these conditions: x < ∘⅗⁄3 or x ≤ ∘⅗/13.

Tracey is looking at two different travel agencies to plan her vacation. ABC Travel offers a plane ticket for $295 and a rental car for $39 per day. M and N travel offers a plane ticket for $350 and a rental car for $33 per day. What is the minimum number of days that Shirley’s vacation should be for M and N Travel to have the better deal?
Shirley/Tracey has to stay at least 10 days for the M and N to cost less
Answer:
10 days.
Step-by-step explanation:
Let d represent number of days.
We have been given that ABC Travel offers a plane ticket for $295 and a rental car for $39 per day. The total cost of travelling x days using ABC travel company would be [tex]39x+295[/tex].
We have been given that M and N Travel offers a plane ticket for $350 and a rental car for $33 per day. The total cost of travelling x days using M and N travel company would be [tex]33x+350[/tex].
To make M and N travel the better deal, we will set an inequality, where total cost of x days using ABC travels is greater than M and N travels as:
[tex]39x+295>33x+350[/tex]
[tex]39x-33x+295>33x-33x+350[/tex]
[tex]6x+295>350[/tex]
[tex]6x+295-295>350-295[/tex]
[tex]6x>55[/tex]
[tex]\frac{6x}{6}>\frac{55}{6}[/tex]
[tex]x>9.166[/tex]
Since the closest integer to 9.1677 is 10, therefore, for a vacation of 10 days using M and N travels will be the better deal.

Answer is 0.17
2. A movie theater charges $5 per ticket and averages 300 customers each night. If prices are raised to $7 per ticket, the theater estimates that average nightly ticket sales will be $1,750. What is the percentage change in ticket prices?
Answer is 0.40
3. A movie theater charges $5 per ticket and averages 300 customers each night. If prices are raised to $7 per ticket, the theater estimates that average nightly ticket sales will be $1,750. What is the elasticity of demand in this situation? (Hint: Elasticity of demand is determined by calculating the ratio of the percentage change in the quantity demanded over the percentage change in price.)
Answer is 0.425
4. Study the following data for a product:
Price Amount produced Amount demanded
$200 100,000 7,000
$100 80,000 35,000
$75 45,000 45,000
$50 30,000 70,000
$20 15,000 90,000
Find the market price. ________? Answer is $75
Step-by-step explanation:
1.) The average nightly ticket sales can be calculated as
Average sales = Average no. of customers per night x Charge per ticket
For the second night, we have
$1750 = (N)($7)
This gives us N = 250.
So, the average number of customers decreased as a result of the price increase.
To calculate the percentage change, we use the following formula:
% change = [tex]\frac{250 -300}{300} X 100[/tex]
We have -17% change in the average number of customers the theater has each night. The negative sign indicates a decrease in the number, which is consistent with our calculations.
2.) % change in prices = [tex]\frac{Final price - Initial price}{Initial price} X100[/tex]
Therefore, we have 40% change in the cost of ticket per person, which reflects an increase in the prices.
3.) Elasticity of Demand = [tex]\frac{ percentage change in quantity demanded}{percentage change in price}[/tex]
Hence, we have [tex]\frac{-17}{40}[/tex] = -0.425
This stands consistent with the Law of Demand - as the price increases, the quantity demanded decreases.
4.) Market price is obtained by looking for a point where the quantity supplied equals the quantity demanded. From the table we see that at $75 price, there is a demand for 45,000 units of that product in that market, which the suppliers are willing to supply. Hence, that defines the market price for that product.

the attendance at a rugby game is as follows no. of men:no. of women:no. of children = 17:9:12
Given that there are 3512 more men than women work out the number of children attending the game
Answer: Number of children is 5268
Step-by-step explanation:
Since we have given that
The ratio of men to women to children is given by
17:9:12
So,
Number of men be 17x
Number of women be 9x
Number of children 12x
According to question, we have there are 3512 more men than women ,
so,
[tex]17x-9x=3512\\\\8x=3512\\\\x=\frac{3512}{8}\\\\x=439[/tex]
So, Number of children is given by
[tex]12x=12\times 439=5268[/tex]
The number of children who attend the game are:
5268
Step-by-step explanation:The ratio of number of men to number of women to the number of children is given by:
17:9:12
Let x be a constant such that we may define:
Number of men are: 17x
Number of women are: 9x
and the number of children are: 12x
There are 3512 more men than women.
This means that:
17x-9x=3512
i.e. 8x=3512
i.e. x=439
Hence, the number of children who attend the game are:
12x=12×439
= 5268

The first equation is open, since it has an unsolvable variable. 1x could be anything!
The second equation is false, because 20 - 11 = 9 not 11.
The last equation is true, 7 + 10 does equal 17!
1x + 4 = 10
x = 10 - 4
x = 6 (true)
--------------------
20 - 11 = 11
20 - 11 = 9 (false)
-----------------------
7 + 10 = 17 (true)

what is the distance between -15 to 20
The distance between -15 and 20 on the number line is 35 units, calculated by taking the absolute difference between the two numbers.
The distance between two points on a number line can be found by taking the absolute difference between those points. To find the distance between -15 and 20, you subtract the smaller number from the larger one and take the absolute value:
|20 - (-15)| = |20 + 15| = |35| = 35
Therefore, the distance between -15 and 20 is 35 units.
