question:The sum of the areas is expressed as a geometric series. So we need to find the formula for that series. We had found a = pi and the common ratio r is 4.
answer:Given that the first term a = π and the common ratio r = 4, we can express the sum of the areas as an infinite geometric series. However, since the common ratio r = 4 is greater than 1, this series diverges. Despite the divergence, we can still express the series using the formula for an infinite geometric series, keeping in mind that it does not converge to a finite value: S = a / (1 - r) Substituting a = π and r = 4: S = π / (1 - 4) However, as we established, the result does not converge. The series can be simply expressed as: S = π + 4π + 16π + ... S = π(1 + 4 + 16 + ...) S = π ∑(4^k) from k=0 to infinity This represents the geometric series for the sum of the areas of the concentric circles.
question:The geometric series formula is S = a / (1 - r). However, we can still use that formula to give us the series. Here the common ratio is 4. So we have pi / ( 1 - 4).
answer:Using the formula for an infinite geometric series, S = a / (1 - r), where a = π and r = 4, we can express the series as: S = π / (1 - 4) S = π / (-3) However, we're interested in the form of the series rather than its convergence. To express the series in a more familiar form, we can rewrite it as: S = -π / 3 Alternatively, we can write it as: S = π / (1 - 4) S = π / (1 - 4^1) Which in turn is equivalent to: S = π * (1 / (1 - 4)) We are ultimately looking for the form of the series so the equation pi / (1-4) is the one.
question:Write a multi-choice question for the following article: Article: The US will have a new president this fall. Voters will decide between the Democratic candidate , Hillary Clinton, and Donald Trump of the Republicans. But the voting is not a must for each person in the US. So quite a lot of people choose not to vote, especially the young generation. According to Fox News, one-in-five young voters between the ages of 18 and 35 said clearly that they wouldn't vote for either of the two candidates. Just 12 percent of voters aged 35-54, and only nine percent of voters aged 55 and older said the same thing. This is not only because young people don't like Clinton or Trump, according to theFortunemagazine. The truth is that they are traditionally less likely to vote than their parents. Young people are not at an age in their life when they think politics or government has anything to do with them, said Rodd Freitag, a political science professor at the University of Wisconsin-Eau Claire, US. But for the older age groups, they have a home, they pay taxes , they care about schools and the community. Many believe that the civic education of an American youth is another reason why they don't vote. Students usually just do community services like cleaning the neighborhoods. This means they haven't learned how to link real life problems to politics through voting, according to Christopher Beem, a politics professor at the Pennsylvania State University. He said the country needs to help young people learn how to take part in politics and get them to see that they can make a difference. A:
answer:Which of the following factors contribute to the low voter turnout among young Americans? A) Disliking the political candidates B) Lack of connection between real life problems and politics C) Being traditionally less likely to vote than their parents D) Insufficient civic education Answer: All of the above (A, B, C, D)
