Keith is saving money for a car. He has saved the same amount each year for the past three years, and records how much he has at the end of each year in the table below. (a)What is Keith's unit rate of change of dollars with respect to time; that is, how much does Keith save in one year? The unit rate is dollars per year. (b)Graph the proportional relationship described above, with the x-coordinate representing years, and the y- coordinate representing amount saved in thousands of dollars.
Answers
Answer:
(a)$1500 per year.
Explanation:
(a)From the table:
3000-1500=$1500
4500-3000=$1500
This means that every year, Keith adds $1500 to his savings.
The unit rate is $1500 per year.
(b)
If x=number of years; and
y=Amount saved (in thousands of dollars.)
When x=1, y=$1.5
When x=2, y=$3.0=2x1.5
When x=3, y=$4.5=3x1.5
The equation of proportion is therefore:
[tex]y=1.5x[/tex]When x=0, y=0 (0,0)
When x=1, y=1.5 (1, 1.5)
We join the points (0,0) and (1,1.5)
The graph of the proportional relationship is attached below.

A lumber yard has fixed costs of $7259.40 per day and variable costs of $0.07 per board-foot produced. Lumbar sells for $1.87 per board-foot. How many board-feet must be produced and sold daily to break even?
Answers
The number of board-feet that must be produced and sold daily to break even is:4033.
How to find the number of board-feet to breakeven?Let the number of board-feet produced per day = x
Let the lumber yard's costs each day be: C =$7259.40+ 0.07x
Let the lumber yard's profits be: P = 1.87x
Let P - C = 0
Hence,
1.87x - ($7259.40 + $0.07x) = 0
1.87x - $7259.40 - 0.07x = 0
Combine like terms
1.8x - $7259.40 = 0
1.8x = $7259.40
Divide both side by 1.8x
x = $7259.40/ 1.8
x = 4033
Therefore the breakeven is 4033.

The vertices of ABCDE are A(-6,0), B(-3,0), C(0, -3), D(-3,-6), and E(-6, -3). Find the vertices of the image after a translation using the rule (x,y) - (x + 9, y-6) and a dilation with a scale factor of 4s centered at the origin.
Answers
Vertices of new image: A' = (12, -24)
B' = (24, -24)
C' = (36, -36)
D' = (24, -48)
E = (12, -36)
Explanation:A(-6,0), B(-3,0), C(0, -3), D(-3,-6), and E(-6, -3)
A translation of (x + 9, y-6)
A becomes A'
A' = (-6 + 9, 0 - 6) = (3, -6)
B(-3,0)
B becomes B'
B' = (-3+9, 0 - 6) = B' (6, -6)
C(0, -3)
C becomes C'
C' = (0+9, -3-6) = C' (9, -9)
D(-3,-6)
D becomes D'
D' = (-3+9, -6-6) = (6, -12)
E(-6, -3)
E becomes E'
E' = (-6+9, -3-6) = (3, -9)
A dilation with scale factor of 4, we multiply the cooordinates of the alphabeths with prime with 4.
Vertices of new image:
A' = 4(3, -6) = (12, -24)
B' = 4(6, -6) = (24, -24)
C' = 4(9, -9) = (36, -36)
D' = 4(6, -12) = (24, -48)
E = 4(3, -9) = (12, -36)

A function is a relationship between two variables that satsifes the condition that there is one and only one value of the image (the dependent variable) for each value of the domain (the set of values of the independent variable).
All the set of values of the image are what is called the range.
1) It is a function, as there is one and only one value of y for each value of x.
The domain, the set of values that x can take, is all the real numbers.
The range, instead, only takes values above y=-3.
Answer:
Function: Yes
Domain: All real numbers
Range: y>=-3.
2) It is a function, as there is one and only one value of y for each value of x.
The domain, the set of values that x can take, is all the real numbers.
The range is also all the real numbers, as the arrows indicate no limit for the values that the function can take.
Answer:
Function: Yes
Domain: All real numbers
Range: All real numbers
3) It is a function, as there is one and only one value of y for each value of x.
The function is defined for values of x that are bigger or equal than -3, so the domain is x>=-3.
The values that the function takes are equal or bigger than 0, so the range is y>=0.
Answer:

The measure of two angles are (2n+18) and (7n-11). If these are vertical angles, what is the value of n.
Answers
Answer:
The value of n is 29/5
Explanation:
Given that (2n + 18) and (7n - 11) are two vertical angles, by definition, they are congruent.
so
2n + 18 = 7n - 11
Subtract 2n from both sides of the equation
2n + 18 - 2n = 7n - 11 - 2n
18 = 5n - 11
Add 11 from both sides of the equation
18 + 11 = 5n - 11 + 11
29 = 5n
Divide both sides by 5
n = 29/5
Answer:
n = 29/5 or 5 4/5

Po = Loan Amount
r = Annual Interest Rate
n = Number of Compounds per year
t = Length of the Loan in years

Part 3
Second, find the number of pieces of data, n.
The number of pieces of data listed is enter your response here.
Answers
The mean, median, mode and midrange are 13, 13, 13, 17 respectively.
Define mean, median, mode and midrange.An average is a mean. To calculate the sum, add together all the numbers. After that, divide the total by the quantity of numbers.
The median is a midpoint. The fact that the median is in the middle of the road makes it easy to recall. Put the numbers in ascending order, lowest to largest. If there are odd numbers, find the middle one. Add the middle two numbers together and divide by two if the numbers are even.
The most frequent number in a group of numbers is called the mode.
The midpoint is discovered by arranging the numbers from smallest to largest. To determine the sum, add the two smallest and greatest numbers together. By 2, divide the total.
Given data -
The following set of numbers is 9, 9, 10, 11, 13, 13, 13, 14, 25
Σx = 117
To calculate the mean, we use the formula as
Mean = Σx / n
where n is the number of pieces of data i.e. n=9
Therefore, Mean = 117 / 9
Mean = 13
To calculate the median, we use the formula as
Median = Value of [tex](\frac{n+1}{2})^{th}[/tex] th observation
when n is an odd number
So, Median = 10/2
Median = 5
Here the [tex]5^{th}[/tex] observation is 13
As 13 occurs maximum number of times in the given set of numbers and it has 3 times in the given set
Therefore the mode = 13
To calculate the midrange, we use the formula as,
Midrange = (greatest number + least number) / 2
Here the greatest number is 25 and least number is 9
Therefore midrange = (25+9)/2
midrange = 34/2
midrange = 17
The mean, median, mode and midrange are 13, 13, 13, 17 respectively.

The scale from a square park to a drawing of the park is 5 miles to 1 miles. The actual park has an area of 1,600 m×2 what is the area of the drawing
Answers
The user corrected that the scale of a drawing of a park reads: 5 miles to 1 cm , and we know that the park measures 1,600 square meters (user insisted that this measure is given in square meters and not square miles).
So we have to convert the 1600 square meters into miles, knowing that 1 meter is the same as: 0.000621371 miles
then meters square will be equivalents to:
1 m^2 = (0.000621371 mi)^2
then 1600 m^2 = 0.00061776 mi^2
now, since 5 miles are represented by 1 cm, then 25 square miles will be represented by 1 square cm
and therefore 0.00061776 square miles will be the equivalent to:
0.00061776 / 25 cm^2 = 0.000024710 cm^2
So and incredibly small number of square cm.
