how is the radius and area of a circle proportional

Answers

Answer 1

Answer:

The factor '2 pi' is simply the constant of proportionality between C and R. So the area of a circle is proportional to R2 and pi is the constant of proportionality between the area and the radius of a circle.

Answer 2

Answer: The relationship between the area of a circle and the radius of the circle can be stated as follows: The area of a circle is proportional to the square of the radius.   Written in symbolic notation: A = R 2 RELATIONSHIP 5.1 Area = x (radius) squared OR A = R 2

Step-by-step explanation:

the mean is all of them added up then divided by how many numbers there are the median is where you put them in order putting the numbers in order then finding the middlel mode is the most of the same numbers and range is the biggest number

Answer:

mean- 104.83

median- 102

mode- 101

range- 28

Step-by-step explanation:

mean is all numbers added together then divided by however many numbers there are. sum of all numbers is 629, divided by 6 is 104.83 repeating.

median is the number in the middle. since there are six numbers and no middle one, the two in the middle (when ordered smallest to largest) are 101 and 103. the number between those two is 102 and therefore the median.

mode is the number that appears the most in the data set, which is 101 in this case.

range is the difference between the largest number and the smallest. the largest number is 121, minus 93, the smallest number, gives you 28.

hope this helps!

If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation. x + y = 24 3x + 5y = 100 What does the solution of this system indicate about the questions on the test? The test contains 4 three-point questions and 20 five-point questions. The test contains 10 three-point questions and 14 five-point questions. The test contains 14 three-point questions and 10 five-point questions. The test contains 20 three-point questions and 8 five-point questions.

Answer:

Step-by-step explanation:

Solve the system of equations

 x +  y  = 24      both sides times 3          3x + 3y = 72

3x + 5y = 100

3x + 3y = 72       subtract  the bottom equation from the top one

0x + 2y = 28

         y = 14   five point questions      70 points

The value of b will determine whether the towns are growing in size or not, For instance;

If b > 1 then the town is growing, else it is declining

You have a jar of Marbles in front of you 2 are Cordovan, 9 are yellow, 3 are white and 7 are red. What is the probability, as a fraction of selecting a marble that is white or yellow, followed by a marble that is Cordovan?​

Answers

Answer:

2/35

Step-by-step explanation:

Assuming that this is without replacement,

The total amount of marbles is 2+9+3+7, or 21.

9 are yellow, 3 are white. this makes 12.

The probability of selecting a white or yellow marble is 12/21.

Now without replacement (comment if it is with replacement.), there are 20 marbles left, and 2 are Cordovan. This means there is a 2/20 chance then of picking a Cordovan marble.

After multiplying the fractions we get

(12/21) * (2/20) = 2/35.

There is a 2/35 chance of selecting a yellow or white, then a cordovan marble.

What is the general equation of a sine function with an amplitude of 6, a period of StartFraction pi Over 4 EndFraction, and a horizontal shift of StartFraction pi Over 2 EndFraction?
y = sine (8 (x minus StartFraction pi Over 2 EndFraction))
y = 8 sine (4 (x minus StartFraction pi Over 2 EndFraction))
y = 6 sine (8 (x minus StartFraction pi Over 2 EndFraction))
y = 6 sine (8 x) + StartFraction pi Over 2 EndFraction

Answers

Answer:

C: [tex]y = 6 \sin (8(x-\frac{\pi}{2} ))[/tex]

Step-by-step explanation:

Amplitude is changed by multiplying the entire trig function by a number, by default the amplitude is 1, so multiplying by 6 is necessary; eliminate A and B

Horizontal shift is going through the x axis, so it must be subtracted from the x value. This is only seen in choice C of the remaining answers.

Calculating the period isn't necessary because we already found the right answer but in case you need it in the future; the period is by default 2pi, to get to pi/4, it had to be 8 times smaller, so multiplying x and translations on x by 8 will get you the correct period.

The General equation of a sine function is f(x) = 6·sin(8(x -π/2)).

What is Sine Function?

The sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle. The sine function is used to find the unknown angle or sides of a right triangle.

Here, Amplitude = 6, P=π/4, and S=π/2

A transformed sine function with amplitude A, period P, and horizontal shift S can be written as ...

 f(x) = A · sin(2π/P(x -S))

 f(x) = 6·sin(8(x -π/2))

The horizontal shift is equal to two full periods, so the shifted function is indistinguishable from the unshifted function.

Thus, the General equation of a sine function is f(x) = 6·sin(8(x -π/2)).
