General information
All of these questions have to do with various translations of the square root function. The first problem deals with the basic function. Other problems translate the graph in various ways.
The basic square root function has its vertex at (0, 0) and is defined for x-values (domain) that are 0 or positive. The resulting y-values (range) are also zero or positive.
The basic function intercepts the x- and y-axes only at the point (0, 0), so both intercepts are 0. Unless the function is reflected vertically or horizontally, its minimum will be at the left end of any interval, and its maximum will be at the right end.
The transformation of a function g(x) to f(x) = g(x -a) +b causes it to be translated 'a' units to the right and 'b' units up. For the functions here, that means the vertex is translated from (0, 0) to (a, b). For the functions here, the vertex values are the limits of the domain and range, so those will be altered accordingly.
Problems
1.
a) The graph is shown in the attachment as f1 (orange).
b) vertex: (0, 0); domain: [0, ∞); range: [0, ∞)
c) x-intercept: 0; y-intercept: 0
d) On the interval [1, 4], the minimum is √1 = 1, and the maximum is √4 = 2.
__
2.
a) The graph is shown in the attachment as f2 (green). The basic function is translated left 1 and down 2.
b) vertex: (-1, -2); domain: [-1, ∞); range: [-2, ∞)
c) x-intercept: 3; y-intercept: -1 (read from the graph)
d) On the interval, [0.5, 5], the minimum is √1.5 -2 ≈ -0.78; the maximum is √6 -2 ≈ 0.45. Min and max values are shown in the table in the second attachment.
__
3.
a) The graph is shown in the attachment as f3 (purple). The basic function is translated up 3.
b) vertex: (0, 3); domain: [0, ∞); range: [3, ∞)
c) x-intercept: (none); y-intercept: 3 (the vertex)
d) On the interval, [2, 4], the minimum is √2 +3 ≈ 4.41; the maximum is √4 +3 ≈ 5. Min and max values are shown in the table in the third attachment.
__
4.
a) The graph is shown in the attachment as f4 (red). The leading multiplier of -2 causes the graph to be reflected over the x-axis and vertically expanded by a factor of 2 before being translated right 2 and up 3.
b) vertex: (2, 3); domain: [2, ∞); range: (-∞, 3]. Note the range is all y-values less than or equal to 3 because of the vertical reflection.
c) x-intercept: 4.25; y-intercept: (none). The x-intercept is found by solving ...
0 = -2√(x -2) +3
(-3/-2)² = x-2
2 +2.25 = x = 4.25
d) On the interval, [4, 7], the minimum is -2√(7 -2)+3 = 3-2√5 ≈ -1.47; the maximum is -2√(4-2)+3 = 3-2√2 ≈ 0.17. Min and max values are shown in the table in the second attachment.

The graph below shows a proportional relationship between xxx and yyy.
What is the constant of proportionality, \dfrac{y}{x}
x
y
start fraction, y, divided by, x, end fraction ?
Answer:
k = 3.5
Step-by-step explanation:
The equation representing a proportional relationship is
y = kx ← k is the constant of proportion
Divide both sides by x , then
k = [tex]\frac{y}{x}[/tex]
Using the point (1, 3.5 ), then
k = [tex]\frac{3.5}{1}[/tex] = 3.5
The constant of proportionality [tex](\(\frac{y}{x}\))[/tex] for the given proportional relationship is 3.5.
To find the constant of proportionality [tex](\(\frac{y}{x}\))[/tex], we can use the two given points (0, 0) and (1, 3.5) on the graph, which represent the proportional relationship between x and y.
The constant of proportionality [tex](\(\frac{y}{x}\))[/tex] is the ratio of y-coordinates to x-coordinates for any pair of corresponding points in a proportional relationship.
Let's calculate it using the points (0, 0) and (1, 3.5):
[tex]\(\frac{y}{x} = \frac{3.5}{1} = 3.5\)[/tex]
So, the constant of proportionality is 3.5.

Kaitlyn's older brother borrowed money for school he took out a loan that charges 6% simple interest he will end up paying 720 and interest after 6 years how much is Kaitlyn's brother borrow for school?
Answer:
529.41
Step-by-step explanation:
From the above question, we are to find the Principal
The formula to find the Principal (Initial amount invested) is =
P = A / (1 + rt)
Where
A = Amount paid after t years. = 720
r = rate of interest = 6% = 0.06
t = time in years = 6
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
P = 720 / ( 1 + (0.06 × 6)) = 529.41176470588
Approximately
P = 529.41
Therefore, Kaitlyn's brother borrowed 529.41 for school

Three dressers are placed side by side. One dresser is 3 feet 9 inches wide, another is 3 feet 3 inches wide, and the third is 5 feet 11 inches wide. How wide are they combined? Write your answer in feet and inches. Use a number less than for inches
Answer:
12 feet 11 inches
Step-by-step explanation:
To solve the above question, we would have to add up all the width of thee dressers together.
Hence:
3 feet 9 inches + 3 feet 3 inches + 5 feet 11 inches
= (3 feet + 3 feet + 5 feet) + (9 inches + 3 inches + 11 inches)
= 11 feet +( 23 inches)
Note that
12 inches = 1 feet
Hence:
11 feet (23 inches/12 inches)
11 feet (1 feet + 11 inches)
= 12 feet 11 inches.
Therefore, the width of the 3 dressers combined = 12 feet 11 inches

an interior design working with a computer program decreases the radius of a circular rug by 10%. By what percent does the area of the circular rug decrease?
Please give an explanation on how to solve this problem, thanks!
Answer:
The decrease is 21%
Step-by-step explanation:
So lets say the Original area is Pi X (Radius^2)
Lets call Radius as R
For the new radius, it would be: R + 0.1R which is 1.1R
The new area is: Pi X 1.1R^2, which going further is 1.21 after squaring 1.1.
The Original area is: Pi X Radius^2
To find the percent decrease, subtract the new area by the original, cross out Pi X Radius squared and you are only left with 21%

John gives 2/3 of his pencils, P, to Roy and then gives 1/4 of the pencils that he has left to Maria. In terms of P, how many pencils does john now have
a. 1/6
b. 1/3
c. 1/4
Answer:
C. 1/4
Step-by-step explanation:
Since John has given 2/3 of his pencils to Roy, he has 1/3 of the total left. To find 1/4 of 1/3, multiply the numbers. 1/4(1/3) = 1/12. This means that he gave 1/12 of the beginning total to Maria. 2/3 can also be written as 8/12, and 1 can be written as 12/12. 12/12 - 8/12 = 4/12, and then 4/12 - 1/12 = 3/12. 3/12 can be simplified into 1/4
Answer:
John's remaining pencils in term of p = p/4
Hence, option 'c' is true.
Step-by-step explanation:
Let 'p' be the total number of pencils
Given that John gives 2/3 of his pencils = 2/3 of p
= 2/3 × p
= 2/3 p
Pencils left:
[tex]p-\frac{2}{3}p[/tex]
Factor out common term p
[tex]p-\frac{2}{3}p=p\left(1-\frac{2}{3}\right)[/tex]
[tex]=\frac{1}{3}p[/tex]
[tex]=\frac{p}{3}[/tex]
Pencils John gave to Maria = 1/4 × p/3 = p/12
The remaining Pencils in terms of 'p' = [tex]\frac{p}{3}-\frac{p}{12}[/tex]
[tex]=\frac{3p}{12}[/tex]
[tex]=\frac{p}{4}[/tex]
Thus, John's remaining pencils in term of p = p/4
Hence, option 'c' is true.
