The coordinates of the vertices of the image of the square are S'(x, y) = (- 1, - 4), T'(x, y) = (- 1, 1), U'(x, y) = (4, 1) and V'(x, y) = (4, - 4).
How to translate a geometric locus set on a Cartesian plane
In this problem we need to make use of a translation on a geometric locus on a Cartesian plane, which is generated by four points representing the vertices of the square. The translation is a kind of rigid transformation, whose formula is shown below:
P'(x, y) = P(x, y) + t(x, y)
Where:
P(x, y) - Original pointt(x, y) - Translation vector.P'(x, y) - Resulting pointIf we know that S(x, y) = (- 6, - 5), T(x, y) = (- 6, 0), U(x, y) = (- 1, 0) and V(x, y) = (- 1, - 5) and t(x, y) = (5, 1), then the locations of the vertices of the triangle are:
S'(x, y) = (- 6, - 5) + (5, 1)
S'(x, y) = (- 1, - 4)
T'(x, y) = (- 6, 0) + (5, 1)
T'(x, y) = (- 1, 1)
U'(x, y) = (- 1, 0) + (5, 1)
U'(x, y) = (4, 1)
V'(x, y) = (- 1, - 5) + (5, 1)
V'(x, y) = (4, - 4)

What two numbers multiplied give you 100 and added give you 21?
Answer: [tex]\frac{21}{2}+\frac{\sqrt{41}}{2}, \frac{21}{2}-\frac{\sqrt{41}}{2}[/tex]
Step-by-step explanation:
Let the two numbers be x and y.
[tex]x+y=21 \implies y=21-x\\\\xy=100\\\\\therefore x(21-x)=100\\\\21x-x^2 =100\\\\x^2 -21x+100=0\\\\x=\frac{21 \pm \sqrt{21^2 -400}}{2}=\frac{21}{2} \pm \frac{\sqrt{41}}{2}[/tex]
Round 34,582 to the nearest thousand.
Answer:
35000
Step-by-step explanation:
So the number is 34582
now look at the hundreds
if it is 5 or over then we add a thousand to and subtract what ever the lower than thosand
and in this case it is 5 so we round UP
and now we have 35000
The answer is 35,000.
To round to the nearest thousand, we look at the last three digits. If these digits are 500 or greater, then we round the thousands digit up, and if they are less than 500, then we round down, keeping the thousand's digit the same.
Since in this case the last three digit consists of 582 which is greater than 500 so we round the thousands digit up i.e. from 4 to 5 in this case.

Anjelah took a hike.She finished in 2 hours and 47 minutes.If she started at 10:15 A.M.,what time did she finish?
Anjelah finished at 1:02 P.M. if she started at 10:15 A.M. and she took 2 hours and 47 minutes to complete it.
According to the question,
We have the following information:
Anjelah finished in 2 hours and 47 minutes.
She started at 10:15 A.M.
Now, we know that there are 60 minutes in an hour (more to know: there are 60 seconds in a minute).
So, we will add 2 hours to 10:15 A.M.:
10:15 + 2:00
12:15 P.M.
(Note that the digits before the colon gives us time in hours and the digits after the colon gives us minutes.)
Now, we will add 47 minutes to it:
12:15 + 0:47
(Now, we know that only 45 minutes can be added to 15 minutes because then it will make an hour. So, 2 more minutes will be added to the next hour.)
So, we have the following expression:
1:02 P.M.
Hence, the time when Anjelah will finish is 1:02 P.M.

The graph below represents the number of miles, y, that Jacob can drive his car for
every gallons of gas. Find the rate of change.
The average rate of change of the given graph is 31.3
How to determine the average rate of changeThe graph of the function is represented as the given parameter
From the graph, we have the following points
(x, y) = (10, 313) and (20, 626)
The average rate of change is the slope of the function and the average rate of change is calculated as
Average rate = [f(b) - f(a)]/[b - a]
Where
(a, f(a)) = (10, 313) and (b, f(b)) = (20, 626)
Substitute the known values in the above equation
So, we have
Average rate = [626 - 313]/[20 - 10]
Evaluate
Average rate = 31.3

When a person is 3 feet from a street light, the length of the shadow grows at a rate of 4 feet per second.
See the figure that illustrates the in question statement, attached.
making use of the related triangle theorem;
4/y = 12/x+y
Cross multiply
4(x+y)=12y
4x+4y = 12y
4x=8y
x/y =2
x=2y
Divide the two sides of the equation by t, where dx/dt = 2 dy/dt. The speed at which the person is walking away from the street light is expressed as dx/dt
The growth rate of the shadow's length is measured by the ratio dy/dt.
Given that dx/dt = 8ft/s
by solving,
dy/dt = 4 ft/s
Hence the rate at which the length of the shadow growing when the person is 3 feet from the street light is 4ft/s

If Rie’s legs are 99cm long, and Rie is 165cm tall. What percentage of Rie’s body is legs?
The percentage of Rie's body that is Rie's legs is: 60%.
What is Percentage?A percentage can be defined as an amount in each hundred or, simply put, a proportion of a quantity in relation of a whole.
How to Find the Percentage of a Quantity in a Whole?To find the percentage of a quantity in a whole, divide the quantity by the whole quantity, then multiply the quotient by 100.
The "whole" in this problem is Rie's height, which is: 165 cm
The "quantity" in the context of this question is the length of Rie's leg, which is: 99 cm.
Therefore, to find the percentage of Rie's legs in Rie's body, we have the following:
99/165 × 100
= 0.6 × 100
= 60%.
Therefore, Rie's leg is 60% of Rie's body.

Using ratio and proportion, Louie is correct.
Ratio is defined as the relationship between two quantities. On the other hand, proportion is defined as the equality between two or more ratios.
From the given graph (see attached photo), the coordinates of Point F and Point G is (4, 8) and (-6, -7).
If the ratio of FP to PG is 4 to 1, then the ratio of the horizontal distance and vertical distance between the two endpoints is also 4 to 1.
FP : PG = 4 : 1
FP/PG = 4/1 = 4
x-coordinate of P
(4 - x)/(x - -6) = 4
(4 - x) = 4(x + 6)
4 - x = 4x + 24
-5x = 20
x = -4
y-coordinate of P
(8 - y)/(y - -7) = 4
(8 - y) = 4(y + 7)
8 - y = 4y + 28
-5y = 20
y = -4
Hence, the coordinates of Point P is (-4, -4).
Therefore, Louie is correct, while Nicky is mistaken probably while setting up the proportion and solving for the coordinates.
