A graph of the image of triangle V'W'X' after a rotation of 90° counterclockwise about the origin is: graph A.
What is a rotation?A rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.
In Geometry, rotating a point 90° about the origin in a counterclockwise (anticlockwise) would produce a point that has the coordinates (-y, x).
Note: Each interval on this graph represents 1 unit.
By applying a rotation of 90° counterclockwise to triangle VWX, the coordinates of the vertices of the image triangle V'W'X' include the following:
(x, y) → (-y, x)
Point V = (-2, -4) → Point V' = (-(-4), -2) = (4, -2)
Point W = (-2, -2) → Point W' = (-(-2), -2) = (2, -2)
Point X = (-5, -4) → Point X' = (-(-4), -5) = (4, -5)

The given series is a geometric sequence with a common ratio of 1/2 it is also written as 0.5.
What is geometric sequence?A geometric progression, also known as a geometric sequence, is a non-zero number sequence in which each term after the first is found by multiplying the previous one by a fixed, non-zero number known as the common ratio.
Number sequences are groups of numbers that adhere to a pattern or rule. A geometric sequence is one in which the rule is to multiply or divide by a specific number each time.
We have,
20, 10, 5, …
The distinction between consecutive terms is:
10 - 20 = -10
5 - 10 = -5
Since -10 ≠ -5, therefore the given series has no standard difference, which means the given sequence is not arithmetic.
The ratio between consecutive terms is:
10/20 = 1/2
5/10 = 1/2
The given series has a common ratio of 1/2, which means the given sequence is geometric. it is also written as 0.5.

Answer:
The first 4 terms are 3,9,15, and 21
Step-by-step explanation:
The first term in the recursive formula is 3 (it is important because that would be the number we substitute for the second term. This logic also applies to finding the next term with the answer to the previous term) The formula is an = a(n-1) + 6. Because of this formula the nth on the right side is the previous one plus 6. With that in mind let find the mext three terms To find a2 you would first substitute n for 2 making it a2 = a(2-1) +6 which is a2 = a1 + 6. We know that the first term is 3 so we substitute a1 for 3 to get a2 = 3 + 6 which is 9. The second term is 9 To find a3 we do the same steps for solving a2 only this time we use the second term to put in place of a2+ 6 which is 9 + 6 which equals to 15. The third term is 15 Again we are doing the same steps to find a4 but we use the third term to substitute for a3 + 6 which is 15 + 6 which equals to 21. The fourth term is 21.There's a image of all of the work above

EXPLANATION:
Given;
We are given a graph of a function.
Required;
We are required to determine from the graph if the function is even, odd or neither even nor odd.
Solution:
To determine this from a graph, we should note that a function which is symmetrical with the y-axis is an even function. The graph which is symmetrical with the origin after a 180 degree rotation is an odd function.
Observe that if this graph is flipped from left to right (across the y-axis), it would not retain its original shape.
However, if the graph is rotated 180 degrees about the origin, it would retain its original shape.
Therefore, the graph depicted is an odd function

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
here, it is given that :
Estimated number of members in his bicycle club by the end of summer = 21
Actual number of members in his bicycle club by the end of summer = 15
Now, the percent error of Ming’s estimate :
percent error = {(21-15)/15 } x 100
percent error = (6/15) x 100
percent error = 40%
Therefore, the percent error of Ming’s estimate is 40%.

What is proportional relationship?
Relationships between two variables that are proportional occur when their ratios are equal. Another way to consider them is that in a proportionate relationship, one variable is consistently equal to the other's constant value. The "constant of proportionality" is the name of this constant. In mathematics, proportionality denotes a linear relationship between two quantities or variables. Both quantities increase in size when one doubles, and both decrease in size when one drops to a tenth of its original value.
Given.
The proportion is: according to the first row of the proportional relationship
y = kx
28 = k*20
k = 28/20 = 1.4
the following is the function:
y = 1.4x
a) Fill in the following table:
Weight and distance (in centimeters) (newtons)
20 | 28
55 | 55*1.4 = 77
140/1.4 = 100 | 140
1 | 1*1.4 = 1.4
b) The scale should take the coefficient 1.4 into account, therefore the x-axis scale will be 100 with 1-cm intervals and the y-axis scale will be 140 with 1.4-newton intervals.

The population that is most dense is the one for 5000 individuals per 200 square meters
Given the following information:
100 individuals per 100m^2
5000 individuals per200m^2
100,000 individuals per 20,000m^2
15,000 individuals per 10,000m^2
We find the population that is most dense using the formula:
Population density=(No. of people/Land area)
For 100 individuals per 100m^2,
Population density=100/100=1
For 5000 individuals per200m^2
Population density=5000/200=25
For 100,000 individuals per 20,000m^2
Population density=100,000/20,000=5
For 15,000 individuals per 10,000m^2
Population density=15,000/10,000=1.5

Adam’s house is 12 miles from his house. It takes his older brother 20 minutes to drive him school. What is his brother’s driving speed
Answers
Step-by-step explanation:
I assume we want ca miles/hour answer as speed.
but just formally, any distance per time unit is speed.
in that sense
12 miles / 20 minutes = 3 miles / 5 minutes
is the speed.
but now to convert this to miles/hour.
we want to multiply 3/5 or 12/20 by f/f, so that the denominator is 1 hour.
by multiplying the numerator by the same value we make sure the speed ratio remains the same.
so, what "f" do we need to multiply 20 with to get 60 (1 hour = 60 minutes) ?
right, f = 3
therefore, we get
12/20 × 3/3 = (12×3)/(20×3) = 36/60 = 36 miles / 1 hour
his brother's driving speed was 36 miles/h or 36 mph.

3(5-x)-2(5+x)=3(x+1) solve for x
Answers
Primarily use the Distributive Property to solve this equation.
3(5 - x) - 2(5 + x) = 3(x + 1)
Distribute the outer terms.
3(5) + 3(-x) - 2(5) - 2(x) = 3(x) + 3(1)
15 - 3x - 10 - 2x = 3x + 3
-3x - 2x + 15 - 10 = 3x + 3
-5x + 5 = 3x + 3
Now, isolate all x terms.
-5x + 5x + 5 = 3x + 5x + 3
5 = 8x + 3
5 - 3 = 8x + 3 - 3

Answers
Not necessarily, because this was not an experiment.
In my opinion, Yet scientific evidence from case studies, surveys of meditator experiences, and historical studies is emerging to show that meditation can be associated with stress, negative effects, and mental health problems. Meditation can induce a state of deep relaxation and a calm mind. During meditation, you focus your attention and eliminate the stream of disorganized thoughts that can fill your mind and cause stress. This process can lead to increased physical and emotional well-being.
