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
Answer: No
Step-by-step explanation:
9/3=3 6x3=18
(2½)/(⅗)=5/2×5/3=25/6 cups of soda to 1 cup of juice=4⅙ cups of soda per cup of juice.
Answer: 
Step-by-step explanation:
Given
The initial population of a city is 
The annual growth rate is 
after 1 year it is

after 2 years, it is

after x years it is

2(4)-(2) / -3 = -2
2•4 is 8 - 2 is 6, 6 divided by -3 is -2.
