Question

bacteria can multiply at an increasing rate. The bacteria doubles every hour, how many bacteria will we have by the end of one 12 hours ?

Answer 1

After 1 hour, 2, then 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096. Add them up. I can't remember the formula to solve it more easily.

Answer 2

It depends upon how many you had to start with doesn't it?
Suppose you had 1 initially
1 to start at 8 a.m
2 at 9
4 at 10
8 at 11
16 at 12 noon
32 at 1 p.m.
64 at 2
128 at 3
256 at 4
512 at 5
1024 at 6
2048 at 7
4096 at 8
or you can use 2^12 = 4098

Answer 3

I'm sorry. My goof. You don't add them. My apologies.

Answer 4

Here is an online calculator in case you don't start with 1 bacterium.
