Explanation:
When I revise, I go through my paper and highlight all the mistakes that I can, using a different color for each kind. Then after I have done that, I just go through and fix them. It helps the revision go quicker and be more manageable.
It is clear that a(n)=2^(1-2^(-n)). In fact, for n=1 this produces 2^(1-1/2)=sqrt(2)=a1 and if it is true for a(n) then a(n+1) = sqrt (2 * 2^(1-2^(-n))) = sqrt(2^(2-2^(-n))) = 2^(1-2^(-(n+1))) (a) clearly 2^(1-2^(-n))<2<3 so the sequence is bounded by 3. Also a(n+1)/a(n) = 2^(1-2^(-n-1) - 1+2^(-n)) = 2^(1/2^n - 1/2^(n+1)) = 2^(1/2^(n+1)) >1 so the sequence is monotonically increasing. As it is monotonically increasing and has an upper bound it means it has a limin when n-> oo (b) 1-1/2^n -> 1 as n->oo so 2^(1-2^(-n)) -> 2 as n->oo
The correct answer is C. Everyone in the community helps take care of Shadow.
Explanation
The text fragment is an allusion to a dog named Shadow, the dog of a neighborhood, this means that he does not have a single owner within the neighborhood. Therefore, it is possible to affirm that by belonging to the neighborhood all the inhabitants of that neighborhood help take care of Shadow because he is the pet of all the people who live there. So the correct answer is C.Everyone in the community helps take care of Shadow.
