Adam descends 5 feet Multiply 5 by four and then you get 30 feet
I got the answer six. I’m not sure how those other answers are possible.
Answer:
-3, -9, -7
Step-by-step explanation:
Answer:
Hour 3
4 * 2 = 8
Hour 4
8 * 2 = 16
Hour 6
32 * 2 = 64
Hour 7
64 * 2 = 128
Hour 12
2048 * 2 = 4096
Step-by-step explanation:
We are told that initially there is a bacterium that doubles every hour, so let's calculate what happens in the first 12 hours every hour.
Hour 0
one
Hour 1
1 * 2 = 2
Hour 2
2 * 2 = 4
Hour 3
4 * 2 = 8
Hour 4
8 * 2 = 16
Hour 5
16 * 2 = 32
Hour 6
32 * 2 = 64
Hour 7
64 * 2 = 128
Hour 8
128 * 2 = 256
Hour 9
256 * 2 = 512
Hour 10
512 * 2 = 1024
Hour 11
1024 * 2 = 2048
Hour 12
2048 * 2 = 4096
We can deduce that the growth of the bacteria is:
2 ^ n
where n is the # of time that has passed
