The error in finding the measure of one exterior angle of a regular polygon lies in using the formula 360°/n, where n is the number of sides of the polygon.

The formula 360°/n is used to find the measure of each exterior angle of a regular polygon. It is based on the idea that the sum of all exterior angles of any polygon is always 360 degrees. However, this formula assumes that the polygon has internal angles of 180°, which is true only for regular polygons.

The error occurs when this formula is applied to a non-regular polygon, as non-regular polygons have varying internal angles. Using the formula 360°/n for a non-regular polygon will give incorrect results because the internal angles are not all equal.

For regular polygons, each exterior angle is indeed 360°/n, and the sum of all exterior angles will be 360 degrees. However, for non-regular polygons, this formula cannot be used, and the measures of exterior angles must be calculated differently based on their internal angles and sides.

The error in finding the measure of one exterior angle of a regular polygon is they divided 360 by 10 instead of 5.

Given that,

There are a total of 10 exterior angles, two at each vertex, so the measure of one exterior angle is 360°/10 = 36°.

Here, at each vertex there are two angles.

So, there must be 5 vertices and 5 sides.

Then, the measure of one exterior angle = 360°/5

= 72°

Therefore, the error in finding the measure of one exterior angle of a regular polygon is they divided 360 by 10 instead of 5.

Answer:

this two graph is not same because they have different slopes for this they are not same

The equation for the line is:

3y - x = 14

Given the line:

x - 3y = 7

This line can be written as:

y = (1/3)x - 7/3

The slope is 1/3

The y-intercept is -7/3

A line parallel to this has the same slope but different y-intercept, written as:

y = (1/3)x + b

Using the given point (-2, 4), with x = -2 and y = 4, we can obtain the value of b

4 = (1/3)(-2) + b

b = 4 + 2/3

= 14/3

Therefore, the line is:

y = (1/3)x + (14/3)

or

3y - x = 14

The term "average" plays a fundamental role in statistics. It refers to a measure of central tendency that summarizes a set of data by representing a typical or representative value.

Calculation for the average of a set of numbers, follow these steps:

Add up all the values in the data set.

Division of the sum by the total number of values.

For example, consider the following data set: 10, 15, 20, 25, 30.

Sum all the values: 10 + 15 + 20 + 25 + 30 = 100.

Divide the sum by the total number of values: 100 / 5 = 20.

In this case, the average of the data set is 20.

The term average provides a concise summary of a data set by representing a typical value. It is calculated by adding up all the values and dividing the sum by the total number of values. The average is a fundamental statistical measure that helps in understanding and analyzing data in various fields such as economics, education, research, and many others.

x- intercept: ( -10,0)

y- intercept: (0, -45)

Step-by-step explanation:

An x intercept can be determined from the graph above by recognizing where the given line crosses the x-axis. The same is true for the y intercept and the y-axis.

On this graph, we see that the line crosses the x axis at the point ( -10,0), making this our x intercept.

We also see that the line crosses the y axis at the point (0, -45), making this our y intercept.

This bound is achieved when z = e^iθ/2, we have:

|f(z)| ≤ 2|a| + 32   for all

To show that f(z) = az^n + b satisfies f(x) = |a| + 16 whenever |z| < 1, we can substitute z = 2 into f(z) and use the fact that |2| < 1:

f(2) = a(2)^n + b

= 2^n(a+b/2^n)

= 2^n|a(1+(b/a)/2^n)|

= |2^n||a(1+(b/a)/2^n)|

= |a|2^n|1+(b/a)/2^n|

Since |2| < 1, we know that 2^n approaches 0 as n approaches infinity. Therefore, as n becomes very large, the expression inside the absolute value approaches 1, and we get:

f(2) = |a|2^n|1+(b/a)/2^n|

≈ |a|2^n

Since f(2) = |a| + 16, we have:

|a| + 16 ≈ |a|2^n

Taking the limit as n approaches infinity, we get:

|a| + 16 = 0

which is a contradiction. Therefore, we cannot find a value of z such that f(z) = |a| + 16 when |z| < 1.

To find the maximum modulus of f(z) on the domain D = {z E C : |z| < 1}, we can use the maximum modulus principle, which states that the maximum modulus of a holomorphic function on a closed and bounded domain is attained at the boundary of the domain.

If b = 0, then f(z) = az^n, and the maximum modulus of f(z) on D is |a|. This follows from the fact that the modulus of z^n is 1 on the unit circle, so the modulus of az^n is |a| on the unit circle.

If b ≠ 0, then we can write b = a(reiθ), where r = |b/a| and θ = arg(b/a). Let z = e^iθ/2. Then |z| = 1/2, so z is on the boundary of D. We have:

f(z) = az^n + a(reiθ)

= a(z^n + reiθ)

= a(e^iθ/2)^n(2^n + reiθ)

= a(2^n + rcosθ + risinθ)

Taking the modulus of this expression, we get:

|f(z)| = |a||2^n + rcosθ + risinθ|

Since r ≤ |b|/|a| and |b| ≤ |a| + 16, we have:

r ≤ (|a| + 16)/|a|

Therefore, we can bound the modulus of f(z) as follows:

|f(z)| ≤ |a||2^n + (|a| + 16)/|a|(cosθ + isinθ)|

Since cosθ and sinθ vary between -1 and 1, we can find a value of θ such that the expression in the brackets is maximized. This value is θ = ±π/2, so we have:

|f(z)| ≤ |a||2^n + 2(|a| + 16)/|a|

Taking the limit as n approaches infinity, we get:

|f(z)| ≤ 2|a| + 32

Since this bound is achieved when z = e^iθ/2, we have:

|f(z)| ≤ 2|a| + 32

The total number of arrangements, we can simply add up the results from each case:

C(21,8) + C(5,1) C(21,7) 8 + C(5,2) C(21,6) 2

Now, We can solve this problem, we can break it down into three cases, based on the number of vowels included in the arrangement.

Hence, Here are the three cases:

Case 1: No vowels included: In this case, we need to select 8 letters from the 21 consonants in the alphabet.

This can be done with C(21,8) ways.

Case 2: One vowel included:

Here, we need to select one of the five vowels and then select 7 letters from the 21 consonants.

The vowel can be placed in any of the 8 positions, but once it is placed, the other vowels must be placed in alphabetical order.

Therefore, the number of arrangements in this case is, C(5,1) C(21,7) 8.

Case 3: Two vowels included: In this case, we need to select two of the five vowels, and then select 6 letters from the 21 consonants.

Again, the vowels must be placed in alphabetical order once they are selected.

However, we have two possible orders to place the vowels - either at the start or in the middle of the 8-letter arrangement.

Therefore, the number of arrangements in this case is C(5,2) C(21,6) 2.

So, The total number of arrangements, we can simply add up the results from each case:

C(21,8) + C(5,1) C(21,7) 8 + C(5,2) C(21,6) 2

To calculate the volume of a rectangular box, you multiply the lengths of its sides.

In this case, the given box has sides measuring 7 inches, 9 inches, and 13 inches. Therefore, the volume can be calculated as:

Volume = Length × Width × Height

Volume = 7 inches × 9 inches × 13 inches

Volume = 819 cubic inches

So, the volume of the given box is 819 cubic inches. The formula for volume takes into account the three dimensions of the box (length, width, and height), and multiplying them together gives us the total amount of space contained within the box.

Answer:

In 25 minutes, the monthly phone charges of both companies will be the same.

Step-by-step explanation:

If we allow m to represent the number of minutes, we can create two equations for C, the total cost of phone charges from both companies:

Phoenix equation:  C = 0.5m + 30

Nuphone equation: C - 0.10m + 40

Now, we can set the two equations equal to each other.  Solving for m will show us how many minutes must Abby use for the total cost at both companies to be the same:

0.5m + 30 = 0.10m + 40

Step 1:  Subtract 30 from both sides:

(0.5m + 30 = 0.10m + 40) - 30

0.5m = 0.10m + 10

Step 2:  Subtract 0.10m from both sides:

(0.5m = 0.10m + 10) - 0.10m

0.4m = 10

Step 3:  Divide both sides by 0.4 to solve for m (the number of minutes it takes for the total cost of both companies to be the same)

(0.4m = 10) / 0.4

m = 25

Thus, Abby would need to use 25 minutes for the total cost at both companies to be the same.

Optional Step 4: Check the validity of the answer by plugging in 25 for m in both equations and seeing if we get the same answer:

Checking m = 25 with Phoenix equation:

C = 0.5(25) + 30

C = 12.5 + 30

C = 42.5

Checking m = 25 with Nuphone equation:

C = 0.10(25) + 40

C = 2.5 + 40

C = 42.5

Thus, m = 25 is the correct answer.
