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

Evelyn borrowed $30 from her mother to buy a sweater. After 3 weeks of babysitting, she pays her mother back $24. What percent of the debt has Evelyn paid her mother back?
Answers
Answer:
80%
Step-by-step explanation:
We know that Evelyn paid off $24 of the $30. To find the percentage, we divide the part by the whole and then multiply by 100. The multiplying by 100 is optional, but it just makes the calculation easier. In this case, the part is 24 and the whole is 30, so our expression would be [tex]\frac{24}{30} * 100[/tex], or 80%. Hope this helps!
WILL GIVE BRAINLIEST The kilopascal is a unit of measure for atmospheric pressure. Suppose the atmospheric air pressure at sea level is about 101 kilopascals. For every 1000-m increase in altitude, the pressure decreases about 11.9%. What is the approximate pressure at an altitude of 2000 m?
Answers
Answer:
The formula to calculate pressure at an altitude in this case is:
P = original pressure x (1 + rate of change)^(number of changing)
in which,
original pressure = 101 kilopascals
rate of change = -11.9% = - 0.119
number of changing = 2000/1000 = 2
=> P = 101 x (1 - 0.119)^2 = 78.39 kilopascals
Hope this helps!

A farmer plants corn in 1/4 of his field. He plants white corn in 3/5 of the corn
section of his field. This situation is shown in the model. What fraction of the
whole field is planted with white corn?
Answers
Answer:
[tex]\frac{3}{20}[/tex]
Step-by-step explanation:
Fraction of the total that is for corn (TC - Total corn):
[tex]TC=\frac{1}{4}[/tex]
fraction of the corn section that is for white corn (WC - white corn in the corn seccion):
[tex]WC=\frac{3}{5}[/tex]
we need to find the fraction of the whole field that is for the white corn.
For this we need to find how much is [tex]\frac{3}{5}[/tex] out of the [tex]\frac{1}{4}[/tex] destinated to corn, and this will be the fraction of the total that is for white corn. We find this fraction by multiplying the fraction of corn ([tex]\frac{1}{4}[/tex]) by the fraction of white corn in the corn section ([tex]\frac{3}{5}[/tex]).
I will call the total fraction of white corn TWC, thus:
[tex]TWC=WC*TC=\\=\frac{3}{5} *\frac{1}{4} \\\\=\frac{3*1}{5*4} \\\\=\frac{3}{20}[/tex]
the answer is: [tex]\frac{3}{20}[/tex] of the whole field is planted with white corn
Dori charges 60 customers £1 to play a game. The probability of a customer winning is 0.35 and the prize is £2. How many of the 60 customers can Dori expect to win and how much profit will Dori make?
Answers
Answer:
21 people will win, so the profit will be £18
Step-by-step explanation:
0.35 x 60 = 21
21 x 2 = 42 (the amount of money to give away to prize winners)
If 60 people enter, she has £60. Subtracting £42 in winning payouts from this leaves her with a £18 profit.

Answer:
The volume of the sphere is 4187 cubic feet, approximately.Step-by-step explanation:
The volume of a spherer is defined as
[tex]V=\frac{4}{3} \pi r^{3}[/tex]
Where [tex]r[/tex] is the radius and [tex]\pi \approx 3.14[/tex]
According to the proble, the diameter is 20 feet. By definition of radius,
[tex]r=\frac{d}{2}=\frac{20ft}{2} =10ft[/tex]
Replacing the radius in the volume formula
[tex]V=\frac{4}{3} \pi (10)^{3}[/tex]
[tex]V=4,187 \ ft^{3}[/tex]
Therefore, the volume of the sphere is 4187 cubic feet, approximately.

Answer:
25 meters
Step-by-step explanation:
Imagine a segment extending vertically down from the left tree to the right tree.
That would make the segment be 25-10, or 15.
Then, we have a right triangle and we can solve for the hypotenuse, which is the length of the rope. (The bottom of the triangle is 20, and the leg is 15.)
We can use the pythag theorem: 15^2+20^2=c^2
c^2=225+400
c^2=625
c=25
Therefore, 25 meters

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.
n = number of compounding periods per unit t; at the END of each period
