C. They restore it to its former beauty.
Hello. You did not inform the text to which this question is referring, which makes it impossible for it to be answered accurately, however, I or try to help you in the best possible way.
It is only possible to actually know the tone of the text by reading it. However, if we analyze the sentence "I'm puzzled at how this so-called a" thing "" we can infer that it contributes to a tone of curiosity and distrust, since the speaker of this sentence, feels like this in relation to "thing "and displays this feeling to the reader.
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
Answer:
D. I let a nervous and shaking breath out of my lungs, and with one pointer finger, pressed the doorbell with the light in it. I heard the two notes of the “ding-dong,” and a dog began to bark very fast, loudly, and in a high-pitched manner.
Well, that is upsetting. I hope she feels better. Lmao
