How do you find radius from cercumference?
(if at all Possible)
Answer:
r = C/2π
Step-by-step explanation:
You just rearrange the Circumference formula so you can find r.
Circumference formula:
C = 2πr
To find r, you multiply 1/2π on both sides of the equation so you can isolate r:
r = C/2π
Which transformations can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4)? a 180degree rotation about the origin a 90degree counterclockwise rotation about the origin and a translation down 4 units a 90degree clockwise rotation about the origin and a reflection over the y-axis a reflection over the y-axis and then a 90degree clockwise rotation about the origin
The transformations that can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4) is C. a 90 clockwise rotation about the origin and a reflection over the y-axis
What is a Transformation?This refers to the mathematical process where one figure or expression is changed from one form to another that has or contains a similar value.
Given the pair of points (x, y) in the original image, it has been transformed to (-y, -x).
If we allow ABC to be first transformed onto A"B"C" by a 90° clockwise rotation, this would result in:
B(4, 1) being mapped onto B''(1, -4).
Therefore, the rule mapping ABC to A"B"C" is (x, y)→(y, -x)
With this, we can conclude that the transformation that maps (y, -x) to (-y, -x) is a reflection with respect to the y-axis
Option C is the correct transformation.

On a coordinate plane, a square has points A (negative 5, 2), B (1, 2), C (negative 4, 1), and D (negative 5, negative 4). If a translation of is applied to square ABCD, what is the y-coordinate of B'?
Answer:
The y coordinates of B' is: 8
Step-by-step explanation:
Given
[tex]A = (-5,2)[/tex]
[tex]B =(1,2)[/tex]
[tex]C = (-4,1)[/tex]
[tex]D = (-5,-4)[/tex]
Translation of (x, y) → (x + 6, y – 10) ---Missing from the question
Required
Determine the y coordinates of B'
We have:
(x, y) → (x + 6, y – 10)
And
[tex]B =(1,2)[/tex]
So the translation from B to B' is:
[tex]B (1,2) \to B'(1+6,2-10)[/tex]
[tex]B (1,2) \to B'(7,-8)[/tex]
So, we have:
[tex]B' = (7,-8)[/tex]
The y coordinates of B' is: 8

There are 8 sophomores on the academic team. At the last competition, they each took the math test. Their scores were 82%, 92%, 76%, 72%, 92%, 74%, 80%, and 78%. What was the median math score of the sophomores? 79% 82% 87% 92%
The median of the math scores is = 79%.
You can understand more about calculation of median of a set of numbers below.
Estimation of median scoresThe total number of sophomores is = 8
The percentage score of each sophomore = 82%, 92%, 76%, 72%, 92%, 74%, 80%, and 78%.
To calculate the median of the percentage scores, arrange the scores in ascending order and pick the figure in the middle as the median math score.
72, 74, 76, 78, 80, 82, 92, 92
Here the median is two figures 78, and 80 which are located in the middle. The median is =>78 +80/2
= 158/2 = 79%
Therefore, the median of the math scores is = 79%

Suppose jamal fell during one race and recorded a time of 210s. Which of the mean, median, and mode would be most affected
Answer:
Mean would be most affected
Step-by-step explanation:
The mean is defined as the average value . If the data has extreme values then the average value automatically changes.
The median is the value which divides the data in to two halves. It is not affected by the extreme values. The middle value remains the same.
The mode is the value which occurs repeatedly. An extreme value in a data does not affect the mode.
For example I have 5 chocolate bars of sizes 5,6,7,7,9 and another 5 chocolate bars of sizes 5,6,7,7,12
Mean for the two sizes will be 34/5= 6.8 and 37/5=7.4
The median and mode in both sets is 7
So the mean is most affected with change in value.

Answer:
A reflection over the line y = x followed by a translation up 3 units
Step-by-step explanation:
Since this is a multiple choice question, let's test each answer out.
First scenario:
"A reflection over the y-axis followed by a translation right 3 units and down 4 units"
Reflect segment XY over the y-axis, we get segment XY between x = 2 and x = 6, on y = 5 line.Translate right 3 units, we get segment XY on y = 5 line, between x = 5 and x = 9.Translate down 4 units, we get segment XY on y = 1 line, between x = 5 and x = 9.Resulting segment does not match segment X'Y', this answer is incorrect
Second scenario:
"A reflection over the line y = x followed by a translation up 3 units"
Reflect segment XY over y = x line, we get segment XY, between y = -2 and y = -6, on x = 5 line.Translate up 3 units, we get segment XY on x = 5 line, between y = 1 and y = -3.Resulting segment matches segment X'Y', this is the correct answer.
Suppose the population of a town is 17,400 and is growing 2% each year.
Predict the population after 9 years.
Answer: 20,532
Step-by-step explanation:
17,400(.02)=348
348(9)=3132
17,400+3132=20,532
Answer:
Step-by-step explanation:
This is an exponential growth function of the form:
[tex]y=ab^x[/tex] where a is the initial population and b is the growth rate. This could also be written as
[tex]y=a(1+r)^x[/tex] which is a bit more accurate. We'll use that one. r is the percent growth: 2% for us.
Filling in the formula:
[tex]y=17400(1+.02)^x[/tex] and then simplifying:
[tex]y=17400(1.02)^x[/tex]
That's the model for this population. Filling in any number of years for x will give you the population y. Our time is 9 years:
[tex]y=17400(1.02)^9[/tex]
Take care of the exponents first, giving us:
[tex]y=17400(1.195092569)[/tex] and then multiply to get
y = 20,794.6 or 20,794 people (since you can't have 6/10 of a person)
