For positive integers $n$, let $f(n)$ return the smallest positive integer $k$ such that $\frac{1}{k}$ has exactly $n$ digits af
disa [49]

Answer:

There are a total of 2011 integer divisors.

Step-by-step explanation:

The only primes p such that 1/p has finite spaces after the coma are 2 and 5. If we divide a number with last digit odd we will obtain 1 extra digit after the decimal point and if we divide a number by 5 we will obtain 1 more digit if that number has a last digit in the decimal which is not a multiple of 5.

If we take powers of those primes we will obtian one more digit each time. In order to obtain more digits it is convinient to divide by a power of 2 instead of a power of 5, because the resulting number will be smaller.

If we want 2010 digits after the decimal point, we need to divide 1 by 2 a total of 2010 times, hence f(2010) = 2²⁰¹⁰, which has as positive integer divisors every power of 2 between 0 and 2010, hence there are a total of 2011 integer divisors of f(2010).

B(1)=−2 b(n)=b(n−1)−7 <br> What's the 3rd term in this sequence?
cestrela7 [59]

Answer:

-16

Step-by-step explanation:

You have given the nth term:  It is equal to the previous term, less 7.

Thus, b(1) = -2 (given)

          b(2) = b(1) - 7, or b(2) = -2 - 7, or b(2) = -9

Then   b(3) = b(2) - 7, or b(3) = -9 - 7 = -16
