2. A

Step-by-step explanation:

1. Because there are 9 zeros.

2.

4096 bytes = 1 page

(8 * 10^9) / 4096 = closet answer is A

If you look at each decimal place it is in decreasing powers of 10, ie...

after the decimal point in our number system you have columns with coefficient values of 10^-1, 10^-2, 10^-3, etc

1/10, 1/100, 1/1000 etc and in this case we have

4/10, 4/100, 4/1000, etc

So it would be C.

Technically the sequence is:

a(n)=(4/10)(1/10)^(n-1)  if we are going to be talking about geometric sequences...
