Let an be a bounded sequence of complex numbers. Show that for each ϵ>0 the series ∑n=1[infinity]ann−z converges uniformly for Rez≥1+ϵ. Here we choose the principal branch of n−z.

Answers

Answer 1

The series ∑(n=1 to infinity) M * n^(-1 - ε) converges by the p-series test, as ε > 0. Therefore, by the Weierstrass M-test, the original series ∑(n=1 to infinity) a_n n^(-z) converges uniformly for Re(z) ≥ 1 + ε.

To show that the series ∑n=1[infinity]ann−z converges uniformly for Rez≥1+ϵ, we need to use the Weierstrass M-test.
First, note that since an is a bounded sequence of complex numbers, there exists a positive constant M such that |an|≤M for all n.
Next, we need to find an expression for |ann−z| that will allow us to bound the series. Since we are choosing the principal branch of n−z, we have |n−z|=n−Rez for Rez≥1. Thus, we have
|ann−z|=|an||n−z|≤M|n−Rez|
Now, we need to find a series Mn such that Mn≥|ann−z| for all n and ∑n=1[infinity]Mn converges. One possible choice is Mn=M/n^2. Then we have
|Mn|=|M/n^2|=M/n^2 and
|Mn−ann−z|=|M/n^2−an(n−Rez)|≥M/n^2−|an||n−Rez|≥M/n^2−M|n−Rez|
Thus, if we choose ϵ>0 such that ϵ<1, then for Rez≥1+ϵ, we have
|Mn−ann−z|≥M/n^2−M(n−1)ϵ≥M/n^2−Mϵ
Now, we can use the Comparison Test to show that ∑n=1[infinity]Mn converges. Since ∑n=1[infinity]M/n^2 converges (p-series with p>1), it follows that ∑n=1[infinity]Mn converges as well.
Thus, by the Weierstrass M-test, we have shown that the series ∑n=1[infinity]ann−z converges uniformly for Rez≥1+ϵ.

The cost of tickets to a school play are $10 for adults and $6 for children under 12. If there were a total of 100 tickets sold to the play on a certain night, what equation would you use to represent the total ticket sales, T, if the number of adult tickets can be represented by a. Show and explain each step to create the equation.

Answers

Answer:

10a+6b=T------------2

Step-by-step explanation:

Given data

Let the number of adults be a

and the number of children be b

we are told that the total tickets is 100

hence

x+y=100-------------1

The cost of adult ticket = $10

The cost of children ticket = $6

since the total cost is T

Hence

10a+6b=T------------2

Answers

Answer:

15 = 2x - 3y

Step-by-step explanation:

We have the two points P1(3,-3) and P2(9,1).

First, calculate the slope between those points:

slope [tex]= \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - (-3)}{9 - 3} = \frac{4}{6} = \frac{2}{3}[/tex]

Now simply move 3 steps from (3,-3) towards the y-axis to get the intersection with the y-axis (each step reduces x by 1 and applies the slope to the y-value):

(3,-3)

---> (2, -3 - (2/3)) = (2,-3 2/3)

---> (1, (-3 2/3) - 2/3) = (1, -4 1/3)

---> (0, (-4 1/3) - 2/3) = (0,-5)

This tells us, that our line intersects the y-axis at (0,-5).

The general form of a line is f(x) = <SLOPE> * x + <Y-VALUEATXEQUALSZERO>.

In our case: f(x) = y = (2/3)x -5.

To get it into the correct form, we simply subtract y from both sides and get:

0 = (2/3)x - y - 5

To get only integers just multiply everything with 3 and add 15 and get:

15 = 2x - 3y, which fulfils the form asked for in the problem.

What is Linear function?

A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.

Given, Tamika is ordering a taxi from an online taxi service. The taxi charges $3.50 just for the pickup and then an additional $0.75 per mile driven.

Let "m" be the miles Tamika is riding along.

Total additional charges = m *0.75

pick up charges = 3.50

So, Total charges Tamika has to pay for m miles = 0.75*m + 3.50

For m = 5 miles

Tamika has to pay for 5 miles = 0.75 * 5 + 3.50

Tamika has to pay for 5 miles = 7.25

Therefore, 7.25$ would a taxi ride cost if Tamika is riding for 5 miles.

The area of a rectangle is 735 in squared. The ratio of the length to the width is 5 : 3. Find the length and the width.

Answers

Answer: Length = 35

Width = 21

Step-by-step explanation:

From the question, we are informed that the area of a rectangle is 735 in squared and that the ratio of the length to the width is 5 : 3.

To find the length and the width of the rectangle goes thus. We should note that the area of a rectangle is the length multiplied by the width.

Therefore, 5x × 3x = 735

15x² = 735

x² = 735/15

x² = 49

x = ✓49

Are the ratios 18:9 and 4:3 equivalent?

Answers

No
18/4 is 4.5
9/3 is 3
So ur answer is no

Answer:

No. (see below)

Step-by-step explanation:

If you match up the ratios like this:

18 : 9

4 : 3

Matching the two numbers (one on top of another, since they correspond to each other), you can see that these are not equivalent.

Here's why:

The top ratio is 18 to 9, which can be represented by 18 total people to 9 girls in the amount of total people.

We know that the number of boys will also be 9 because 9 is half of 18.

Let's look at the second ratio:

This can be represented by 4 total people to 3 girls in the amount of total people.

4 - 3 = 1

So there would be only 1 boy. Meaning that they're not equal because 1 is not half of 4. It would only be 1/4.

1/4 ≠ 1/2

If we make them similar denominators, you can really see it:

1/4 ≠ 2/4
