The population of a bacteria culture doubles every 2 minutes. Approximately how many minutes will it take for the population to grow from 1,000 to 500,000 bacteria
Is not quite that.
min 0 - 1,000
min 2 - 2,000=1,000*2^1
min 4 - 4000=1000*2^2;
min 6 - 8000=1000*2^3
Be careful! It doubles every 2 minutes.
So, 1,000*2^x=500,000
2^x=500. It asks you to approx. You know that 2^9=512, so x=9.
Because the pop doubles every 2 minutes, the result=9*2=18 minutes.
hope it's perfect!
