Answer:
Scale factor is 3/2
Step-by-step explanation:
Just take any coordinate of any point that was scaled and that had a non-zero initial value. Let’s take the x axis of Q. There’s [tex]x_Q = -2 \land x_{Q'} = -3[/tex].
So, the scaling factor has to be [tex]\frac{x_{Q'}}{x_Q} = \frac{-3}{-2} = \frac{3}{2}[/tex]. You can confirm that [tex]\frac{x_{Q'}}{x_Q} = \frac{y_{Q'}}{y_Q} = \frac{x_{R'}}{x_R} = \frac{x_{S'}}{x_S} = \frac{y_{S'}}{y_S}[/tex]. (I omitted [tex]\frac{y_{R'}}{y_R}[/tex] because of zero values)
The algebraic rule for getting the point [tex]P'(x_{P'}, y_{P'})[/tex] in the dilated space from any given point [tex]P(x_P, y_P)[/tex] is [tex]\left \{ {{x_{P'} = \frac{3}{2}x_P} \atop {y_{P'} = \frac{3}{2}y_P}} \right.[/tex]

Sally used 8 cubes to make this square frame that has 3 cubes on each side. If she uses 20 cubes to make a square frame, how many cubes will be on each side of the frame? Think of using objects to help you solve this problem.
Answer:
5
Step-by-step explanation:
The number of cubes that should be on each side of the frame should be considered as the 5.
Calculation of the number of cube:Since Sally used 8 cubes to make this square frame that has 3 cubes on each side.
So here the no of the cube be like
= 8 - 3
= 5
hence, The number of cubes that should be on each side of the frame should be considered as the 5.

A lottery win is inversely proportional to the number of tickets matching the correct numbers. If 20 tickets have the correct numbers, the winners each receive £1400. One week, each person receives £3500. How many tickets matched the correct numbers?
Answer: 8
Step-by-step explanation:
Given
lottery win is inversely proportional to the number of tickets matching the correct number.
Suppose lottery amount is given by A and no. of tickets by n then
[tex]\Rightarrow A\propto \frac{1}{n}\\\Rightarrow A\cdot n=\text{constant}[/tex]
Initially A=£1400, n=20
then A=£3500, n=?
Product in both the case is same
[tex]\therefore \quad 1400\times 20=3500\timesn\\\Rightarrow n=8[/tex]
There are 8 tickets that matched the correct numbers
A scale drawing of a rectangular park is 5 inches wide and 7 inches ong. The actal prake is 280 yards long. What is the area of the actual park, in square yards?
Given:
A scale drawing of a rectangular park is 5 inches wide and 7 inches long.
The actual park is 280 yards long.
To find:
The area of the actual park.
Solution:
Length of drawing = 7 inches
Length of actual park = 280 yards
The scale factor is
7 inches : 280 yards
1 inches : 40 yards
The width of the drawing is 5 inches. So, the width of actual part is
[tex]40\times 5=200 yards[/tex]
The area of the actual park is
[tex]Area=Length \times width[/tex]
[tex]Area=280\times 200[/tex]
[tex]Area=56000[/tex]
Therefore, the area of the actual park is 56000 sq. yards.

The mean age of 5 people in a room is 26 years.
A person enters the room.
The mean age is now 33.
What is the age of the person who entered the room?
The mean age of 5 people in a room is 26 years. A person enters the room. the mean age is now 33 so the age of the person 68 who entered the room.
In statistics, in addition to the mode and median, the mean is one of the measures of central tendency. Simply put, the mean is the average of the values in the given set. It indicates that values in a particular data set are distributed equally. The three most frequently employed measures of central tendency are the mean, median, and mode. The total values provided in a datasheet must be added, and the sum must be divided by the total number of values in order to determine the mean. When all of the values are organized in ascending order, the Median is the median value of the given data. While the number in the list that is repeated a maximum of times is the mode.
So According to the question, the Mean of 5 people in a room =26
When a person enters the room mean age becomes = 33
The sum of their age is = 5*6 =130
when other persons enter the room means the total person becomes =6
and the sum of their age after another person enters the room= [tex]x+130[/tex]
where x is the age of the other person entering the room.
so, mean = 33= (130+x)/6
then, 130+x=6*33
And,130+x=198
so,x=198-130 =68

If a person's speed doubles and all else remains the same, what will be the person's angular momentum
Answer:
The person's angular momentum will be double
Step-by-step explanation:
Let
Speed of person=v
Mass of person=m
Radius=r
Speed of person=2v
We have to find the person's angular momentum when the speed of person is double and all else remains same.
We know that
Angular moment ,L=mvr
Using the formula
Angular momentum of person when speed 2v
L'=m(2v)r
[tex]\frac{L'}{L}=\frac{m(2v)r}{mvr}=2[/tex]
[tex]L'=2L[/tex]
Hence, the angular moment of person will be double when the speed of person is double.

The graph of f(x) = x2 was transformed to create a graph g(x) =f(x)−6.
Which statement about the graphs is true?
A) The vertex of the graph of g is 6 units above the vertex of the graph of f.
B) The vertex of the graph of g is 6 units to the right of the vertex of the graph of f.
C) The vertex of the graph of g is 6 units to the left of the vertex of the graph of f.
D) The vertex of the graph of g is 6 units below the vertex of the graph of f.
Answer:
A
Step-by-step explanation:
Option D is correct. The vertex of the graph of g is 6 units below the vertex of the graph of f.
What is intercept?The equation y = mx + c is the general equation of any straight line where m is the slope of the line and c is the y-intercept.
According to the question we have
[tex]f(x) = x^{2} \\g(x) = f(x)-6[/tex]
From the above function it is clear that the equation for the graph of g(x) will be
[tex]g(x) = x^{2} -6[/tex]
Since, the y intercept of function f(x) is zero, therefore the function g(x), 6 units below the intercept of the function f(x).
Hence, option D is correct. The vertex of the graph of g is 6 units below the vertex of the graph of f.
