The value of a car decreases about 7% percent each year after it is manufactured.The 2017 Honda Civic costs $19,540
Answer: a) , where 'A' is the value of car after 't' years.
b) $12446.784
Step-by-step explanation:
Given: A new car that sells for $21,000 depreciates (decreases in value) 16% each year.
Then a function that models the value of the car will be
, where 'P' is the selling price of car, 'r' is the rate of depreciation in decimal, 't' is the time in years and 'A' is the value of car after 't' years.
Thus after substituting given value, the function becomes
To find the value after 3 years, substitute t=3 in the above function.
Hence the value of car after 3 years=$12446.784
The value of a car such as the 2017 Honda Civic decreases approximately 7% per year after manufacture. This is an example of exponential decay. After the first year, the car's value would be close to $18,172.
Explanation:The value of a car declining annually after its manufacture is an example of exponential decay in mathematics. In the case of the 2017 Honda Civic costing $19,540, the value decreases by approximately 7% each year. To calculate this, we can use the formula for exponential decay which is A = P(1 - r), where A is the final amount, P is the initial amount (price of the car), r is the rate of decrease (in decimal form), and n is the number of time periods (years in this case).
Now, if you want the value of the car after its first year, replace P with $19,540, r with 0.07, and n with 1. When calculating this, you should get a value close to $18,172, which is the approximate value of the car one year after it was manufactured.

please help | A department store buys 400 shirts at a cost of $6,400 and sells them at a selling price of $20 each. Find the percent markup.
The department store's percent markup on the shirts is 25%. This was determined by dividing the markup price by the cost price and then multiplying by 100.
Explanation:The question asks to find the percent markup of shirts by a department store. First, we need to determine the cost per shirt, which we do by dividing the total cost by the number of shirts. In this case, $6,400 divided by 400 gives us a cost of $16 per shirt.
Next, we subtract the cost from the selling price to find out the markup per shirt. So, $20 (selling price) minus $16 (cost price) gives us a markup of $4 per shirt.
To find the percent markup, we divide the markup by the cost price and multiply by 100. Hence, $4 (markup price) divided by $16 (cost price), and then multiplied by 100, results in a 25% markup.

Answer:
10 2/15 hours
Step-by-step explanation:
If we have a candle that is 11 2/5 inches tall
It burns 1 1/8 inches per hour. We need to divide to see how long the candle will last
11 2/5 ÷ 1 1/8
I will convert the mixed numbers to improper fractions
11 2/5 = (5*11+2)/5 = 57/5
1 1/8 = (8*1+1)/8 = 9/8
57/5 ÷ 9/8
Copy dot flip
57/5 * 8/9
456/45
Now we change it back to a mixed number
45 goes into 456 10 times with 6 left over
10 6/45
This simplifies to 10 2/15

On a piece of paper, graph this system of inequalities. then determine which answer choice matches the graph you drew and identify the number of solutions.
y>3x+9
Y<3x-1
Answer:
(0) no solutions.
Step-by-step explanation:
You are given two inequalities:
[tex]y>3x+9,\\ \\y<3x-1.[/tex]
The signs of both inequalities are > and < (without notion "or equal to"), then the boundary lines should be dotted lines. Each of these dotted lines divides the coordinate plane into two parts. You have to determine which of these parts you have to choose.
Substitute the coordinates of the origin (0,0) into these inequalities:
[tex]0>3\cdot 0+9\Rightarrow 0>9,\\ \\0<3\cdot 0-1\Rightarrow 0<-1.[/tex]
Both results are false inequalities, this means that origin doesn't belong to the shaded region. So you have to choose those parts, that do not contain origin (see attached diagram).
As you can see, shaded regions do not intersect (because lines y=3x+9 and y=3x-1 are parallel), so the system has no solutions.
Answer:

C. 560%
D. 0.56%
Answer: 1) A. 41% (2)B. 0.15
(3) C. 560%
Step-by-step explanation:
In question 1, all you need to do is to count the number of shaded box, and tho total boxes are 100, so number of shaded box/100
=41/100 = 41%
In question (2)
15/100,whenever you shift a decimal to the left hand side the zero will go away, so shiftingit twice to the left handside,the two zeros will go away, so you will have 0.15
In question3
5.6 to percentage,
Simply multiply by 100/100

Answer:
-3 <= x <=8
Step-by-step explanation:
-16 -3|2x-5| >= -49
The first step is to get the absolute value alone. We need to add 16 to each side.
-16+16 -3|2x-5| >= -49+16
-3|2x-5| >= -33
Now divide each side by -3. This will flip the inequality.
(-3/-3)|2x-5| =< -33/-3
|2x-5| =< 11
This is where we can separate the absolute value inequality into 2 pieces, one positive and one negative. Remember to flip the inequality symbol when we take the negative inequality.
2x-5 <=11 and 2x-5>=-11
Add 5 to each side.
2x-5+5 <=11+5 and 2x-5+5>=-11+5
2x<=16 and 2x>=-6
Divide by 2 on each side.
2x/2<=16/2 and 2x/2>=-6/2
x <=8 and x >=-3
Rewrite as a compound inequality
-3 <= x <=8

Graph 2.
Step-by-step explanation:
When you replace x with x - h, the functions shifts horizontally h units.
Here you are replacing x with x + 4. To write x + 4 in the x - h form, you must write x - (-4) making h = -4. f(x + 4) has a shift of -4 units, or 4 units to the left, compared to f(x).
The function f(x) = x^3 included point (0, 0). It goes up to the right of (0, 0), and down tot eh left of (0, 0).
The answer is graph 2. which shows a shift of 4 units to the left compared with the graph of f(x) = x^3.

b. 27/x^3y^3
c. y^3/27x^3
d. 27x^3/y^3
Answer:
y^3/(27 x^3)
Step-by-step explanation:
Simplify the following:
((3 x)/y)^(-3)
((3 x)/y)^(-3) = (y/(3 x))^3:
(y/(3 x))^3
Multiply each exponent in y/(3 x) by 3:
(y^3)/((3 x)^3)
Multiply each exponent in 3 x by 3:
y^3/(3^3 x^3)
3^3 = 3×3^2:
y^3/(3×3^2 x^3)
3^2 = 9:
y^3/(3×9 x^3)
3×9 = 27:

Ms. Hussain told her class that some dilations make figures bigger, some make figures smaller, and some make figures stay the same size.
Select two of the scale factors that support Ms. Hussain's claim that some dilations make figures smaller.
Answer:
To make the figures smaller, scale factor must be divided.
Step-by-step explanation:
1) Firstly, consider a pentagon ABCDE, if we take the scale factor 1\3, the dilations will be smaller.
As distance between A and B = 6
after dilation, distance between A' and B' = 2
Similarly continuing for each side, we get the figure smaller A'B'C'D'E' which is smaller than the original figure.
2) Secondly, consider a hexagon ABCDEF, if we take scale factor 1\2, the dilated figure will be smaller.
A s distance between A and B = 4
After dilations, distance between A' and B' = 2
Similarly continuing for each side, we get the figure A'B'C'D'E'F' which is smaller than the original figure.
Final answer:
Two scale factors that make figures smaller, according to Ms. Hussain's claim, are 2 inches to 8 feet (1/48) and 6 inches to 48 feet (1/96), as they are both less than one and would result in smaller dilated figures.
Explanation:
To support Ms. Hussain's claim that some dilations make figures smaller, we look for scale factors that are less than one because these scale factors reduce the size of the original figure. When reviewing the scale factors presented:
2 inches/8 feet13 inches/12 feet6 inches/24 feet11 inches/33 feet16 inches/32 feet18 inches/36 feet6 inches/48 feet6 inches/12 feetThe scale factors that make the figures smaller are 2 inches to 8 feet (which simplifies to 1/48) and 6 inches to 48 feet (which simplifies to 1/96), since both are less than 1. The original figures are 48 times and 96 times larger than their dilated figures, respectively. Both of these would result in a decrease in size when the original figures are dilated using these factors.
