The new area is 4A and the new circumference is 2C.
To find the new area of the circle, we need to use the formula for the area of a circle: A = πr^2, where r is the radius of the circle. If we double the radius, we get a new radius of 2r. So, the new area can be found as:
New Area = π(2r)^2 = π(4r^2) = 4πr^2Thus, the new area is four times the original area.
To find the new circumference of the circle, we use the formula for the circumference of a circle: C = 2πr. Doubling the radius, we get a new radius of 2r. So, the new circumference can be found as:
New Circumference = 2π(2r) = 4πr
Thus, the new circumference is four times the original circumference.

Cumulative frequency distributions show the accumulated counts up to and including the current bin as the bin limits increase. This means that for each bin, the cumulative frequency distribution includes the number of observations in that bin and any previous bins with lower limits.
If a data set is divided into five bins, and the number of observations falling into each bin are 10, 20, 30, 40, and 50, the cumulative frequency distribution for each bin would be 10, 30, 60, 100, and 150 respectively.
In other words, the cumulative frequency distribution is the total count of observations up to and including the current bin. This makes it easier to see the overall pattern of the data, and can be used to find the median, quartiles, and percentiles of a data set.
It is important to note that cumulative frequency distributions differ from frequency distributions, which only show the number of observations in each bin. Cumulative frequency distributions can also be used to calculate the total number of observations in any bin, including bins that have higher limits.

A credit card with an APR of 28% has a balance of $1000 on it. You make a $400 payment that posts on the 11th day of a 31-day month. How much interest will you be charged for the month?
To calculate the interest charged for the month on a credit card with a balance of $1000 and an APR of 28% after making a $400 payment on the 11th day of a 31-day month, we need to first calculate the average daily balance for the month.
The average daily balance is calculated as follows:
(Previous balance × number of days in billing cycle) + (New charges × number of days since posting of new charges) - (Payments and credits × number of days since payment/credit) / Number of days in billing cycle
In this case, the previous balance is $1000, the number of days in the billing cycle is 31, the new charges are 0, the number of days since posting of new charges is 20 (since the payment posted on the 11th day of the month), the payment/credit is $400, and the number of days since payment/credit is 21. Plugging in these values, we get:
($1000 × 31) + (0 × 20) - ($400 × 21) / 31 = $727.10
Therefore, the average daily balance for the month is $727.10.
To calculate the interest charged for the month, we multiply the average daily balance by the daily periodic rate, which is the APR divided by 365 (since there are 365 days in a year):
$727.10 × (0.28 / 365) × 31 = $19.97
Therefore, the interest charged for the month is $19.97.
Suppose angles 3 and 4 are complementary and ∠3 = 27°.
What is the measure (in degrees) of ∠4? (Do not include the degree symbol)
The measure (in degrees) of ∠4 would be 63 degree
What is complementary angles?If the total of the measurements of two angles equals 90 or 180 degrees, respectively, such angles are said to be complimentary and supplementary.
Complementary angles are the one whose combined angle is exactly 90 degrees. 30 degrees and 60 degrees, for instance, are complementary angles.
A triangle's three angles add up to 180 degrees. The third angle is the result of 64 degrees being subtracted.
They have the same measurements, m 4 = 90.
A + 27 = 90
A = 63
Therefore, they are complimentary, their combined angles equal 90.
A = 63 degree

What is Number Line?A number line is a straight line drawn horizontally where the numbers are placed at an equal intervals.
Given a number line, where it is divided into twelfths, with each twelfth labeled.
So the labeled numbers are [tex]\frac{1}{12}[/tex], [tex]\frac{2}{12}[/tex], ..............[tex]\frac{10}{12}[/tex], [tex]\frac{11}{12}[/tex], [tex]\frac{12}{12}[/tex].

There is a distance of [tex]\frac{10}{12}[/tex] - [tex]\frac{7}{12}[/tex] = [tex]\frac{3}{12}[/tex].
So the first form of expression is [tex]\frac{10}{12}[/tex] - [tex]\frac{3}{12}[/tex] in order to get [tex]\frac{7}{12}[/tex].
Then the dashed arrow starts from [tex]\frac{7}{12}[/tex] and ends at [tex]\frac{3}{12}[/tex].
There is a distance of [tex]\frac{7}{12}[/tex] - [tex]\frac{3}{12}[/tex] = [tex]\frac{4}{12}[/tex].
So the second form is [tex]\frac{7}{12}[/tex] - [tex]\frac{4}{12}[/tex] in order to get [tex]\frac{3}{12}[/tex].

A subspace of M2x2(F) is a set of all diagonal matrices, which are matrices of the form [a,0;0,b] with a,b∈F. This means that all the diagonal entries in the matrix must be non-zero. To find a linearly independent set that generates this subspace, we can start by considering the simplest form of a diagonal matrix, which is [1,0;0,0]. This vector is linearly independent, as it cannot be expressed as a linear combination of any other vector in the space. Similarly, [0,0;0,1] is also linearly independent, as it can't be expressed as a linear combination of any other vector.
These two vectors form a linearly independent set that generates the subspace of diagonal matrices in M2x2(F). Any diagonal matrix can be written as a linear combination of these two vectors. For example, the matrix [2,0;0,3] can be expressed as 2[1,0;0,0]+3[0,0;0,1]. Thus, this set of vectors is sufficient to generate the entire subspace.

What is an angle ?An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.
Interior angles:- The inner angle made by the intersection of two polygonal sides.
Exterior angles:- The outer angle made by the intersection of two polygonal sides.
To find the height of the plane, we can use the following formula:
height = horizontal distance x tanα
Plugging in the given values, we have:
height = 4,812 × tan(12°)
= 4,812 × 0.21213

Use the definition of a Taylor series to find the first four nonzero terms of the series for f(x) centered at the given value of a. (Enter your answers as a comma-separated list.) f(x) = 4 cos-(x), а 3D 0 4, 82 3 32 4 512 90
The first four nonzero terms of the Taylor series for f(x) = 4 cos(x), centered at a = 3π/4, are: 4 cos(3π/4), -4 sin(3π/4), -4 cos(3π/4), 4 sin(3π/4)
The Taylor series for a function f(x) centered at a value "a" is given by:
f(x) = f(a) + f'(a)(x - a) + (f''(a))/2! (x - a)^2 + (f'''(a))/3! (x - a)^3 + ...
To find the first four nonzero terms of the Taylor series for f(x) = 4 cos(x), centered at a = 3π/4, we need to evaluate the function and its derivatives at x = 3π/4:
f(3π/4) = 4 cos(3π/4)
f'(3π/4) = -4 sin(3π/4)
f''(3π/4) = -4 cos(3π/4)
f'''(3π/4) = 4 sin(3π/4)
Now we can plug these values into the Taylor series to get:
f(x) = 4 cos(3π/4) - 4 sin(3π/4)(x - 3π/4) - 4 cos(3π/4) (x - 3π/4)^2 + 4 sin(3π/4) (x - 3π/4)^3 + ...
The first four nonzero terms of the series are:
f(x) = 4 cos(3π/4) - 4 sin(3π/4)(x - 3π/4) - 4 cos(3π/4) (x - 3π/4)^2 + 4 sin(3π/4) (x - 3π/4)^3
So, the first four nonzero terms of the Taylor series for f(x) = 4 cos(x), centered at a = 3π/4, are:

the measures of two consecutive angles of a parallelogram are in ratio 5:4. what is the measure of an obtuse angle of the parallelogram? justify your answer. you can support your answer by the diagram.
The measure of the obtuse angle of the parallelogram is 136 degrees. To justify this, let the measures of the consecutive angles be 5x and 4x.
Since opposite angles of a parallelogram are equal, the other consecutive angle measures must also be 5x and 4x. The sum of the measures of the angles in a parallelogram is 360 degrees, so we have:
5x + 4x + 5x + 4x = 360
18x = 360
x = 20
Therefore, the consecutive angles measure 100 degrees and 80 degrees. Since the opposite angles of a parallelogram are equal, the obtuse angle must be the supplement of one of the 100-degree angles, which is 180 - 100 = 80 + 56 = 136 degrees. This can be confirmed by drawing a diagram of a parallelogram with these angle measures.

Subgroups of order 3= {(), (1 2 3), (1 3 2)}, each of order 3
Subgroup of order 4= {(), (1 2 4 3), (1 4)(2 3), (1 3)(2 4)}, of order 4
Full group A4: {all even permutations, order 12}
What is a subgroup?A subgroup is a subset of a group that is itself a group under the same group operation.
We have,
Group A4 is the group of even permutations of four elements.
It has order 12.
i.e
4! = 24 total permutations of four elements, but half of them are odd and thus not in A4.
To find all the subgroups of A4.
We can use the fact that the order of a subgroup must divide the order of the group.
Thus, the possible orders of subgroups are 1, 2, 3, 4, 6, and 12.
And,
We also know that there is a subgroup of order 1 (the trivial subgroup, consisting of just the identity permutation) and a subgroup of order 12 (the full group A4).
To find the other subgroups,
We can look for elements that generate subgroups of different orders.
One useful element to consider is the 3-cycle (1 2 3), which generates a subgroup of order 3.
This subgroup consists of the identity, the 3-cycle (1 2 3), and the 3-cycle (1 3 2).
There are two such subgroups in A4, corresponding to the three possible choices of which element to leave out of the 3-cycle.
Another useful element is the 2-cycle (1 2), which generates a subgroup of order 2.
This subgroup consists of the identity and the 2-cycle (1 2).
There are three such subgroups in A4, corresponding to the three possible pairs of elements to include in the 2-cycle.
Now,
We can consider the product of the 3-cycle (1 2 3) and the 2-cycle (1 2), which is the 4-cycle (1 2 4 3).
This generates a subgroup of order 4, consisting of the identity, the 4-cycle (1 2 4 3), and the two 2-cycles (1 4) and (2 3).
Thus,
The subgroups of A4 and their orders are.
Subgroups of order 2 = {(), (1 2), (1 3), (1 4), (2 3), (2 4), (3 4)}, each of order 2
Subgroups of order 3= {(), (1 2 3), (1 3 2)}, each of order 3

Step-by-step explanation:lol
suppose that 4 j of work is needed to stretch a spring from its natural length of 36 cm to a length of 49 cm. (a) how much work is needed to stretch the spring from 40 cm to 44 cm? (round your answer to two decimal places.) j (b) how far beyond its natural length will a force of 50 n keep the spring stretched? (round your answer one decimal place.) in cmfor part a I tried .3 and .28 but both were wrong and b I got 156.5 but was also wrong
(a) The work required to stretch the spring from 36 cm to 49 cm is 4 j. (b) A force of 50 N will keep the spring stretched by 13 cm beyond its natural length, or to a total length of 49 cm + 13 cm = 62 cm.
(a) The work required to stretch the spring from 36 cm to 49 cm is 4 j.
Let x be the additional length needed to stretch the spring from 40 cm to 49 cm.
Then, the work required to stretch the spring from 40 cm to 49 cm is (4 j / 13) * x, since it takes 4 j to stretch the spring by 13 cm.
We have x = 9 cm - 4 cm = 5 cm. Therefore, the work required to stretch the spring from 40 cm to 49 cm is (4 j / 13) * 5 = 20 j / 13, or approximately 1.54 j when rounded to two decimal places.
(b) Let k be the force constant of the spring. We can use Hooke's law, which states that F = kx, where F is the force applied, x is the displacement from the natural length, and k is the force constant.
We know that a force of 50 N is required to stretch the spring from 36 cm to 49 cm, which is a displacement of 13 cm.
Therefore, we have 50 N = k * 13 cm, or k = 50 N / 13 cm.
Let y be the displacement from the natural length when a force of 50 N is applied to the spring.
Then, we have 50 N = k * y, or y = 50 N / k. Substituting k = 50 N / 13 cm, we get y = (50 N / (50 N / 13 cm)) = 13 cm.
Therefore, a force of 50 N will keep the spring stretched by 13 cm beyond its natural length, or to a total length of 49 cm + 13 cm = 62 cm. When rounded to one decimal place, this is 62.0 cm.

How many times smaller is 5 x 10−7 than 8.5 x 10^
−4? HELP ASAP
The scientific notation of 5 x 10−7 is 5 x 10 to the power of negative 7.
What is notation?Notation is a set of symbols and instructions used to represent numbers, equations, and other mathematical expressions. Notation is used to explain rules and procedures, as well as make complex mathematical concepts easier to read and understand. Notations can range from simple abbreviations to complex mathematical symbols. In mathematics, notation can help to simplify complex problems and provide a way for mathematicians to communicate their ideas.
This means that it is 5 times as small as 1. The scientific notation of 8.5 x 10^−4 is 8.5 x 10 to the power of negative 4. This means that it is 8.5 times as small as 1. Therefore, 5 x 10−7 is 8.5 times smaller than 8.5 x 10^−4. By dividing the two numbers, we get 8.5/5 = 1.7. This means that 5 x 10−7 is 1.7 times smaller than 8.5 x 10^−4.
