Rotation
Step-by-step explanation:
Rotation is where you rotate a figure about a point on a graph. Reflection would essentially mirror a figure across and axis, translation would move a figure, and dilation woukd change the size of the figure.
Find the value of r.
Note: Write your answer as a decimal.
Answer:
[tex]\huge\boxed{\sf r = 10.5}[/tex]
Step-by-step explanation:
Since it is a right-angled triangle, it has base, perpendicular and hypotenuse.
Base = r
Perpendicular = 14
Hypotenuse = r + 7
Using Pythagoras theorem:
[tex](Hypotenuse)^2 = (Base)^2+(Perp)^2[/tex]
Put the values
(r + 7)² = (r)² + (14)²
Using formula a² + 2ab + b² = (a + b)²
r² + 14r + 49 = r² + 196
Subtract r² to both sides
14r + 49 = 196
Subtract 49 to both sides
14r = 196 - 49
14r = 147
Divide 14 to both sides
r = 147 / 14
r = 10.5

Find the area and circumference of the circle if It is 13 in
Answer:
Area: 531 in²
Circumference: 82 in
Step-by-step explanation:
Given:
radius = 13 inchesπ = 3.14round to nearest whole numberTo find:
AreaCircumferenceArea of Circle:
[tex]\displaystyle \large{A=\pi r^2}[/tex]
A = areaTherefore:
[tex]\displaystyle \large{A=3.14 \cdot 13^2}\\\displaystyle \large{A=530.66 }[/tex]
Round to nearest whole number:
If the digit is at least or greater than 5, round to 1.If the digit is less than 5, don’t do anything.Therefore, the area is 531 inches squared
Circumference of Circle:
[tex]\displaystyle \large{C=2\pi r}[/tex]
C = circumferenceTherefore:
[tex]\displaystyle \large{C=2\cdot 3.14 \cdot 13}\\\displaystyle \large{C=81.64}[/tex]
Round to nearest whole number:
Hence, the circumference is 82 inches
If \cos\theta = \frac{2}{\sqrt{14}}cosθ= 14 2 and angle \thetaθ is in Quadrant I, what is the exact value of \tan 2\thetatan2θ in simplest radical form?
θ is in quadrant I, so cos(θ) and sin(θ) and hence tan(θ) are all positive.
Recall that
sec²(θ) = 1 + tan²(θ)
We have
cos(θ) = 2/√14 ⇒ sec(θ) = √14/2 = √(7/2)
Then
tan(θ) = +√(sec²(θ) - 1) = √(5/2)
Also recall the identities
sin(x + y) = sin(x) cos(y) + cos(x) sin(y)
cos(x + y) = cos(x) cos(y) - sin(x) sin(y)
from which we get
tan(x + y) = (sin(x) cos(y) + cos(x) sin(y)) / (cos(x) cos(y) - sin(x) sin(y))
tan(x + y) = (tan(x) + tan(y)) / (1 - tan(x) tan(y))
so that
tan(2θ) = 2 tan(θ) / (1 - tan²(θ)) = -(2√10)/3

The number of links on a chain is proportional to the length of the chain. If 25 links create a chain that is 21.25 inches long, than how many links are in a chain that is 80.75 inches long
Answer:
95
Step-by-step explanation:
21.25 times 4 is 85
so it's 3 point something
then you do 80.75 divided by 21.25 and get 3.8 and then 25 times 3.8 is 95
Links are in a chain that is 80.75 inches long are 95.
The number of links on a chain is proportional to the length of the chain.
If 25 links create a chain that is 21.25 inches long,
then how many links are in a chain that is 80.75 inches long.
What are the inches?The inch can be defined as a unit of length in the customary system of measurement.
21.25 times 4 is 85.
Then you divided 80.75 by 21.25.
[tex]\frac{80.75}{21.25} =3.8[/tex]
Then 25 times 3.8 is 95
[tex]3.8\times 25=95[/tex]

Determine the missing information in the paragraph proof.
Given: Line PQ contains points (w, v) and (x, z) and line P'Q' contains points (w + a, v + b) and (x + a, z + b). Lines PQ and P'Q' are parallel.
Prove: Parallel lines have the same slope.
On a coordinate plane, 2 lines are shown. Line Q P goes through (w, v) and (x, z). Line Q prime P prime goes through (w + a, v + b) and (x + a, z + b).
Since slope is calculated using the formula m = StartFraction v 2 minus v 1 Over x 2 minus x 1 EndFraction, the slope of both lines is equivalent to ________. It is given that the lines are parallel, and we calculated that the slopes are the same. Therefore, parallel lines have the same slopes.
StartFraction v minus z Over w minus x EndFraction
StartFraction w minus x Over v minus Z EndFraction
StartFraction v minus z + b Over x minus z + a EndFraction
StartFraction w minus x + a Over v minus z + b EndFraction
Answer:
A
Step-by-step explanation:
The missing line is slopes of both lines are equivalent to (z - v) / (x - w)
What is slope?The slope of a line in the plane containing the x and y axes is generally represented by the letter m, and is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
Given is proof of line PQ is parallel to the line P'Q',
So,
Slope = change in y / change in x
Slope of PQ = (z - v) / (x - w)
Slope of P'Q' = (z + b - (v + b)) / ((x + a) - (w + a))
Slope of P'Q' = (z - v) / (x - w)
The slopes of both lines are equivalent to (z - v) / (x - w)
Hence, the missing line is slopes of both lines are equivalent to (z - v) / (x - w)

Sampling distributions describe the distribution of:.
Answer:
A sampling distribution is a statistic that is arrived out through repeated sampling from a larger population.
It describes a range of possible outcomes that of a statistic, such as the mean or mode of some variable, as it truly exists a population.
The majority of data analyzed by researchers are actually drawn from samples, and not populations.
Step-by-step explanation:
In statistics, a sampling distribution or finite-sample distribution is the probability distribution of a given random-sample-based statistic. If an arbitrarily large number of samples, each involving multiple observations (data points), were separately used in order to compute one value of a statistic (such as, for example, the sample mean or sample variance) for each sample, then the sampling distribution is the probability distribution of the values that the statistic takes on. In many contexts, only one sample is observed, but the sampling distribution can be found theoretically.

They are exempt from income tax and we would get the income tax withheld as $340
What is income tax?Income tax is a tax applied on individuals or entities concerning income or profit earned by them.
You earn $1,166 gross taxable income every week and have claimed no exemptions. assuming that you have no other sources of income.
Gross taxable Income = $ 1,166
Rate of Income tax = 30%
Amount of income tax = 30 % of 1,166
= 30/100 × 1,166
= $339.6
= $340
Therefore. they are exempt from income tax and we would get the income tax withheld as $340.
