Estimate the magnitude of the error involved in using the sum of the first two terms to approximate the sum of the entire series summation from n equals 1 to infinity left parenthesis negative 1 right parenthesis superscript n plus 1 baseline startfraction left parenthesis 0.08 right parenthesis superscript n over n endfraction

Answers

Answer:

the magnitude of the error is 2.9959 × 10⁻⁹

Step-by-step explanation:

By Alternating series estimation theorem

[tex]\sum ^{\infty}_{n=1}(-1)^{n+1}a_n=a_1-a_2+a_3-a_4...+a_n[/tex] is satisfies

(i) [tex]a_n +1\leq a_n[/tex] for all n

(ii) [tex]\lim_{\rightarrow \infty}a_n=0[/tex]

The formula for magnitude of error is

[tex]|R_n|=|s-s_n|\leq a_n+1[/tex]

Let [tex]a_n = \frac{(0.08)^n}{n}[/tex]

We can see [tex]\frac{(0.08)^n^+^1}{n} \leq \frac{(0,08)^n}{n}[/tex]

For all n ∈ N

That means [tex]b_{n+1}\leq b_n[/tex] for all   n ∈ N

[tex]\lim_{n \rightarrow \infty}a_n=\lim(\frac{(0.08)^n}{n} )\\\\=\frac{(0.08)^{\infty}}{\infty}[/tex]

[tex]\lim_{n\rightarrow \infty}a_n =0[/tex]

The alternating series estimation theorem is [tex]|R_s| = |s-s_n|\leq a_{n+1}[/tex]

After stop adding the term with n = 6

the series tells that the error is smaller than the term with a

Therefore

[tex]a_7 = \frac{(0.08)^7}{7} \\\\= \frac{20.97152}{7} \times 10^-^9\\\\=2.9959\times10^-^9[/tex]

the magnitude of the error is 2.9959 × 10⁻⁹

Answers

2415 are females, this can be found out by multiplying 3450 by 70% (0.7)

There are 2415 females in the country.

What is a percentage?

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

There are 3450 people in a country.

It was recently estimated that females outnumber males by seven to three.

That means,

70% are the females.

So, the number of females,

= 70% of, 3450

= 70 x 3450 / 100

= 2415.

Therefore, 2415 females are in the country.

Jason knows that the equation to calculate the period of a simple pendulum is , where T is the period, L is the length of the rod, and g is the acceleration due to gravity. He also knows that the frequency (f) of the pendulum is the reciprocal of its period. How can he express L in terms of g and f?

Answers

Answer:

[tex]L=\dfrac{g}{4\pi^2 f^2}[/tex]

Step-by-step explanation:

The equation to calculate the period of a simple pendulum is: [tex]T=2\pi \sqrt{\frac{L}{g} }[/tex]

Where:

T is the periodL is the length of the rod; and g is the acceleration due to gravity.

Likewise, Frequency (f) of the pendulum [tex]f=\frac{1}{T}[/tex] therefore [tex]T=\frac{1}{f}[/tex]

We want to express L in terms of g and f.

From

[tex]T=2\pi \sqrt{\frac{L}{g} }[/tex]

[tex]T=\frac{1}{f}[/tex]

[tex]\frac{1}{f}=2\pi \sqrt{\frac{L}{g} }\\$Divide both sides by 2\pi\\\dfrac{1}{2\pi f}=\sqrt{\dfrac{L}{g} }\\$Square both sides\\\left(\dfrac{1}{2\pi f}\right)^2=\dfrac{L}{g}[/tex]

[tex]\dfrac{1}{4\pi^2 f^2}=\dfrac{L}{g} \\$Multiply both sides by g\\Therefore: L=\dfrac{g}{4\pi^2 f^2}[/tex]

2(t+1) = 102(t+1)=10 t=?

Answers

Answer:

t = 9/10. Try to substitute the t value into all the t's to see if the answer is correct. Ex: 2t+2, 2(9/10) + 2

Step-by-step explanation:

First you are going to multiply the 2 with the t+1, which is 2t+2. Then you are going to do the same with the other side of the equation. 102 times t+1 is 102t+102.

Now the equation is 2t+2 = 102t+102 = 10

You are now going to combine like terms, 2t - 102t = 102 - 2  = 10

-100t = 100 = 10.

Now subtract 100 from 100 and 10, which makes it: -100t = -90

Then you are going to make the -100t = -90 to -10t = -9, finally it is t = 9/10

Quincy has $6,000 in a savings account that earns 4% interest, compounded annually.

To the nearest cent, how much interest will he earn in 5 years?

Use the formula B = p(1 + r)t, where B is the balance (final amount), p is the principal (starting amount), r is the interest rate expressed as a decimal, and t is the time in years.

Answers

Answer:

A = $ 7,299.92

A = P + I where

P (principal) = $ 6,000.00

I (interest) = $ 1,299.92

Step-by-step explanation:

A = P(1 + r/n)^nt

Where:

A = Accrued Amount (principal + interest)

P = Principal Amount

I = Interest Amount

R = Annual Nominal Interest Rate in percent

r = Annual Nominal Interest Rate as a decimal

r = R/100

t = Time Involved in years, 0.5 years is calculated as 6 months, etc.
