[tex] \rm\sum_{n=1}^{\infty}\sum_{m=1}^{\infty} \frac{( - 1 {)}^{n + 1} }{ {mn}^{2} + mn + {m}^{2} n} \\ [/tex]​

Answers

Let [tex]S[/tex] denote the sum. We can first resolve the sum in [tex]m[/tex] by factorizing and decomposing into partial fractions.

[tex]\displaystyle S = \sum_{n=1}^\infty \sum_{m=1}^\infty \frac{(-1)^{n+1}}{mn^2 + mn + m^2n} \\\\ ~~~~ = \sum_{n=1}^\infty \frac{(-1)^{n+1}}n \sum_{m=1}^\infty \frac1{m(m+n+1)} \\\\ ~~~~ = \sum_{n=1}^\infty \frac{(-1)^{n+1}}{n(n+1)} \sum_{m=1}^\infty \left(\frac1m - \frac1{m+n+1}\right)[/tex]

Rewrite the [tex]m[/tex]-summand as a definite integral. Interchange the integral and sum, and evaluate the resulting geometric sums.

[tex]\displaystyle \sum_{m=1}^\infty \left(\frac1m - \frac1{m+n+1}\right) = \sum_{m=1}^\infty \int_0^1 \left(x^{m-1} - x^{m+n}\right) \, dx \\\\ ~~~~~~~~ = \int_0^1 \sum_{m=1}^\infty \left(x^{m-1} - x^{m+n}\right) \, dx \\\\ ~~~~~~~~ = \int_0^1 \frac{1 - x^{n+1}}{1 - x} \, dx \\\\ ~~~~~~~~ = \int_0^1 \sum_{\ell=0}^n x^\ell \, dx \\\\ ~~~~~~~~ = \sum_{\ell=0}^n \int_0^1 x^\ell \, dx \\\\ ~~~~~~~~ = \sum_{\ell=0}^n \frac1{\ell+1} \\\\ ~~~~~~~~ = \sum_{\ell=1}^{n+1} \frac1\ell = H_{n+1}[/tex]

where

[tex]H_n = \displaystyle \sum_{\ell=1}^n \frac1\ell = 1 + \frac12 + \frac 13 + \cdots + \frac1n[/tex]

is the [tex]n[/tex]-th harmonic number. The generating function will be useful:

[tex]\displaystyle \sum_{n=1}^\infty H_n x^n = -\frac{\ln(1-x)}{1-x}[/tex]

To evaluate the remaining sum to get [tex]S[/tex], let

[tex]\displaystyle f(x) = \sum_{n=1}^\infty \frac{H_{n+1}}{n(n+1)} x^{n+1}[/tex]

and observe that [tex]S=\lim\limilts_{x\to-1^+} f(x)[/tex], which I'll abbreviate to [tex]f(-1)[/tex]. Differentiating twice, we have

[tex]\displaystyle f'(x) = \sum_{n=1}^\infty \frac{H_{n+1}}n x^n[/tex]

[tex]\displaystyle f''(x) = \sum_{n=1}^\infty H_{n+1} x^n[/tex]

[tex]\displaystyle \implies f''(x) = -\frac{\ln(1-x)}{x^2(1-x)} - \frac1x[/tex]

By the fundamental theorem of calculus, noting that [tex]f(0)=f'(0)=0[/tex], we have

[tex]\displaystyle \int_{-1}^0 f'(x) \, dx = f(0) - f(-1) \implies f(-1) = -\int_{-1}^0 f'(x) \, dx[/tex]

[tex]\displaystyle \int_x^0 f''(x) \, dx = f'(0) - f'(x) \implies f'(x) = -\int_x^0 f''(t) \, dt[/tex]

[tex]\displaystyle \implies S = f(-1) = \int_{-1}^0 \int_x^0 \left(\frac{\ln(1-t)}{t^2(1-t)} + \frac1t\right) \, dt \, dx[/tex]

Change the order of the integration, and substitute [tex]t=-u[/tex].

[tex]S = \displaystyle \int_{-1}^0 \int_{-1}^t \left(\frac{\ln(1-t)}{t^2(1-t)} + \frac1t\right) \, dx \, dt \\\\ ~~~ = - \int_{-1}^0 \left(\frac{(1+t) \ln(1-t)}{t^2(1-t)} + \frac1t + 1\right) \, dt \\\\ ~~~ = -1 - \int_{-1}^0 \left(\left(\frac2{1-t} + \frac2t + \frac1{t^2}\right) \ln(1-t) + \frac1t\right) \, dt \\\\ ~~~ = -1 - \int_0^1 \left(\left(\frac2{1+u} - \frac2u + \frac1{u^2}\right) \ln(1+u) - \frac1u\right) \, du[/tex]

For the remaining integrals, substitute and use power series.

[tex]\displaystyle \int_0^1 \frac{\ln(1+u)}{1+u} \, du = \int_0^1 \ln(1+u) d(\ln(1+u)) = \frac{\ln^2(2)}2[/tex]

[tex]\displaystyle \int_0^1 \frac{\ln(1+u)}u \, du = - \int_0^1 \frac1u \sum_{k=1}^\infty \frac{(-u)^k}k \, du \\\\ ~~~~~~~~~~~~~~~~~~~~~~ = - \sum_{k=1}^\infty \frac{(-1)^k}k \int_0^1 u^{k-1} \, du \\\\ ~~~~~~~~~~~~~~~~~~~~~~ = - \sum_{k=1}^\infty \frac{(-1)^k}{k^2} = \frac{\pi^2}{12}[/tex]

[tex]\displaystyle \int_0^1 \frac{\ln(1+u) - u}{u^2} \, du = - \int_0^1 \frac1{u^2} \left(\sum_{k=1}^\infty \frac{(-u)^k}k + u\right) \, du \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ = -\int_0^1 \frac1{u^2} \sum_{k=2}^\infty \frac{(-u)^k}k \, du \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ = - \sum_{k=2}^\infty \frac{(-1)^k}k \int_0^1 u^{k-2} \, du \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ = -\sum_{k=2}^\infty \frac{(-1)^k}{k(k-1)} \\\\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ = \sum_{k=1}^\infty \frac{(-1)^k}{k(k+1)} = 1 - 2\ln(2)[/tex]

Tying everything together, we end up with

[tex]S = -1 - \left(2 \cdot \dfrac{\ln^2(2)}2 - 2 \cdot \dfrac{\pi^2}{12} + (1-2\ln(2))\right) \\\\ ~~~ = \boxed{\frac{\pi^2}6 - 2 + 2\ln(2) - \ln^2(2)}[/tex]

How to find the three consecutive odd numbers?

The sum of three consecutive odd integers is 321.

Odd numbers are numbers that when divided by 2 produces a remainder.

let

x = first odd numbers

Therefore,

x + x + 2 + x + 4 = 321

combine the like terms

x + x + x + 2 + 4 = 321

add the like terms

x + x + x + 2 + 4 = 321

3x + 6 = 321

subtract 6 from both sides

3x + 6 = 321

3x + 6 - 6 = 321 - 6

3x  = 315

divide both sides by 3

x = 315 / 3

x = 105

Therefore, the consecutive odd numbers that sum up to 321 are 105, 107 and 109.

Which company's distribution has the larger dispersion (answer either 'A' or 'B')?

The variance for Company A is _____? (whole numbers only)

Answers

Using the normal distribution, we have that:

A.

The middle 95% of the wires from Company A tested between 420 and 580 psi.The middle 50% of the wires of Company A tested between 473 psi and 527 psi.

B. Due to the higher coefficient of variation, Company A has the larger dispersion.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

For Company A, the mean and the standard deviation are given as follows:

[tex]\mu = 500, \sigma = 40[/tex]

The Empirical Rule is applicable for a normal variable, meaning that 95% of the measures are within 2 standard deviations of the mean, hence:

500 - 2 x 40 = 420.500 + 2 x 40 = 580.

The middle 95% of the wires from Company A tested between 420 and 580 psi.

The middle 50% is the measures between the 25th percentile(X when Z = -0.675) and and the 75th percentile(X when Z = 0.675), hence:

25th percentile:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

-0.675 = (X - 500)/40

X - 500 = -0.675(40)

X = 473.

75th percentile:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

0.675 = (X - 500)/40

X - 500 = 0.675(40)

X = 527.

The middle 50% of the wires of Company A tested between 473 psi and 527 psi.

Which Company had the larger dispersion?

The company with the larger dispersion has the highest coefficient of variation, given by the standard deviation divided by the mean.

Hence:

Company A: 40/500 = 0.08.Company B: 20/600 = 0.033.

Hence Company A has the larger dispersion.

Which function has the greater average rate of change over the interval [0,3]?

Answers

If the interval is [0,3] then the second function whose graph is given has the greater average rate of change.

Given two functions, one is in the table and the other one is in the form of graph.

We are required to choose the function which has the greater average rate of change.

Function is basically the relationship between two or more variables that are expressed in equal to form. The values that we enter are known as part of domain and the values that we get from the function are known as part of codomain or range of the function.

If we observe the table then we will find that in the interval [0,3] there is not any change in the value of function, it is constant to be 4.

If we observe the graph then we will find that the value of function is continuously decreasing.

So, the second function has greater average rate of change over the interval [0,3].

Hence if the interval is [0,3] then the second function whose graph is given has the greater average rate of change.

Write a formula for the perimeter of the rectangle in terms of its length, l.

Answers

a formula for the perimeter of the rectangle in terms of its length, l will be given as l = P / 2 - b.

We know that the perimeter of rectangle is given by:

Perimeter ( P ) = 2 ( l + b )

Now, we need to represent this formula in terms of length that is l.

So, we get that:

P = 2 l + 2 b

Now subtract 2 b from both the sides:

P - 2 b = 2 l + 2 b - 2 b

P - 2 b = 2 l

2 l = P - 2 b

Divide both the sides by 2:

2 l / 2 = (P - 2 b) / 2

l = P / 2 - b

A modulus function always outputs positive values, hence the outputs are greater than or equal to zero,f(x) ≥ 0.

When a graph is reflected along x-axis f(x) becomes -f(x).

∴ The function f(x) = |x| - 5 when reflected along x-axis it will become

Samir measured a boarding school and made a scale drawing. He used the scale 10 millimeters = 2 meters. What is the scale factor of the drawing?

Answers

The scale factor of the drawing is 1 / 200 or 0.005.

What is scale factors?

Scale factor is used to scale shapes in different dimensions.

In other words, Scale factor is described as the number or the conversion factor which is used to change the size of a figure without affecting its shape.

Therefore, scale factor can be represented mathematically as follows:

Scale factor = dimensions of the new shape ÷ dimensions of the original shape.

Hence he uses the scale 10 millimetres equals to 2 meters.

We have to convert metres to millimetres to get the scale.

10millimetres = 2meters

Therefore,

1 meter  =  1000 millimetres.

2 meters = ?

cross multiply

length = 2 × 1000 = 2000 millimetres

Therefore, the scale factor of the drawing is as follows:

scale factor = 10 / 2000

scale factor = 1 / 200

scale factor = 0.005

Therefore, the scale factor of the drawing is 1 / 200 or 0.005.

What is the inverse of f(x)=(3x)2 for x≥0

Answers

The inverse of the function f(x) = (3x)^2 is f-1(x) = 1/3√x

How to determine the inverse of the function?

The function is given as:

f(x) = (3x)^2

Remove the bracket in the above equation

So, we have:

f(x) = 9x^2

Express f(x) as y

So, we have

y = 9x^2

Swap the positions of x and y

So, we have

x = 9y^2

Make y the subject of the formula

y^2 = x/9

Take the square root of both sides

y = 1/3√x

Express as an inverse function

f-1(x) = 1/3√x

Hence, the inverse of the function f(x) = (3x)^2 is f-1(x) = 1/3√x

A = P(1+r)tn
The formula above is used to calculate compound interest. A represents the amount of money accumulated after n years, including interest; P is the initial principal amount (i.e.,
the initial amount deposited); stands for the annual rate of interest as a decimal; and t
represents the number of years and in the number of times the interest is compounded, per
year. If Serina deposits $500 in an account earning 5% interest compounded semiannually and keeps the money in her account for three years, how much money will she have at the end of the five years? Round your answer to the
nearest dollar.
A $515.00
B $530.00
C $670.05
D$710.10

Answers

Answer:

670.05

Step-by-step explanation:

Rounding to the nearest dollar, Serina will have $515 at the end of five years. Therefore, correct option is A.

To calculate the amount Serina will have at the end of five years, we can use the formula for compound interest:

A = [tex]P(1 + r)^{(nt)[/tex]

Where:

A = the future value of the investment/loan, including interest

P = the principal amount (initial deposit)

r = the annual interest rate (in decimal form)

n = the number of times that interest is compounded per year

t = the number of years the money is invested for

In this case, Serina deposits $500 with an annual interest rate of 5%, compounded semiannually (n = 2), and keeps the money in her account for three years (t = 3).

Plugging in the values, we get:

A = 500(1 + 0.05)⁶

A = 500(1.005)⁶

A ≈ 500(1.030)

A ≈ $515

Therefore, correct option is A.
