Answer:
19.61505096...
Step-by-step explanation:
Area in a circle is pi(ratio)squared
Circumference is pi multiplied by diameter
Ratio is half of diameter
15.7 divided by pi is roughly 5 (4.997465213 to be exact)
Half of 5 is 2.5
pi(2.5)squared is 19.61505096...

A linear function is shown below. Choose the two points that are on the graph of the inverse of this function.
A- (-1, 4)
B (2 , -6)
C ( 2, -2)
D ( 1, 0)
E ( 0 , -1 )
F ( -4 , 3)
The points (2, -2) and (0, -1) lies on the inverse of the function y = (-x -2)/2 if the function is y = -2x - 2 option (C) and (E) are correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
In the graph, a linear equation is represented.
We can find the function of linear equation from the two points:
(-1, 0) and (0, -2)
x/-1 + y/-2 = 1
2x + y = -2
y = -2x - 2 ..(1)
From the equation, first take subject as x and find the value of x
2x = -y -2
x = (-y -2)/2
Replacing x→y and y →x
y = (-x -2)/2
The inverse of a function:
y = (-x -2)/2
Points (2, -2) and (0, -1) lies on the inverse of the function(refer to attached picture)
Thus, the points (2, -2) and (0, -1) lies on the inverse of the function y = (-x -2)/2 if the function is y = -2x - 2 option (C) and (E) are correct.

d.157 m²
Answer:
(a) 452 m²
Step-by-step explanation:
The lateral area of a cylinder is given by the formula ...
A = 2πrh . . . . radius r, height h
__
The given tube has an outside (or inside) area of ...
A = 2(3.14)(5 m)(14.4 m) = (3.14)(144 m²) ≈ 452 m²
Each curved surface of the tube has an area of about 452 m².
A discounted concert ticket costs $14.50 less than the original price p. You pay $53 for a discounted ticket. Write an equation that can be used to find the original price.
Answer:
p - 14.5 = 53
Step-by-step explanation:
The original price is p.
The discounted price is $14.50 less than p, or $14.50 subtracted from p. The discounted price is p - 14.5.
The discounted price is $53
Equation:
p - 14.5 = 53

From the table we can conclude that after 2 minutes the height of the water is increased by 4.
Example: In minute 2 it was 8 inches, in minute 4 it was 12 inches. (12-8=4)
This means that if the height of the water is increased by 4 inches for 2 minutes, then for 1 minute is increased 4/2=2 inches.
The following statement best describes how the slope relates to the height of the water in the pool:
The height of the water increases 2 inches per minute.

Because there are no red marbles on the bag, we will see that the probability is zero.
How to find the probability?We want to find the probability that the marble will be red. Viktoria knows that her bag has no red marbles, then it is impossible to get a red marble.
The probability of an impossible event is 0 (suppose that there are 10 marbles in the bag, we have a probability of 0 out of 10 of getting a red marble).

Answer:
m∠K = 36°
m∠L = 54°
m∠M = 90°
Step-by-step explanation:
A triangle's angles add up to 180 degrees. We will add together all the angles and set them equal to 180. Then, we will solve for x. Lastly, we will solve for the angle measurements.
-> The little "box" in angle M means that it is equal to 90°
90° + (2x + 42)° + (4x + 12)° = 180°
90° + 42° + 12° + 2x° + 4x°= 180°
144° + 6x°= 180°
6x° = 36°
x = 6°

At LaGuardia Airport for a certain nightly flight, the probability that it will rain is 0.18 and the probability that the flight will be delayed is 0.14. The probability that it will not rain and the flight will leave on time is 0.74. What is the probability that the flight would leave on time when it is not raining? Round your answer to the nearest thousandth.
The probability that the flight would leave on time when it is not raining is: 0.522
What is probability?Probability is the likelihood of an event happening or not.
Analysis:
pr( it will rain) = 0.18
Pr( it will not rain) = 1 - 0.18 = 0.82
Pr ( flight will be delayed) = 0.14
Pr( it will not be delayed) = 1 - 0.14 = 0.86
Pr( it will not rain and flight would leave early) = 0.74
Pr( flight leave early when not raining) = pr( it willnot rain) x Pr( it will not be delayed) x Pr( it will not rain and flight leave on time) 0.82 x 0.86 x 0.74 = 0.522
In conclusion, the probability that flight would leave on time when it is not raining is 0.522

How can you verify using distance that the center of rotation is the origin?
If the distance between the origin and the points on the path of rotation is equal, the origin will be the center of rotation for any system.
What is center of rotation?Center of rotation is the point about which the rotation takes place. this point is equidistant from all points in the path of rotation.
We are asked to verify that the center of rotation is the origin.
In this case, the center of rotation will be equidistant from all the points in the locus of rotation. So, the distance between the origin and any point on the path of rotation will be equal.
Thus, if the distance between the origin and the points on the path of rotation is equal, origin will be the center of rotation for any system.
