Bacteria Growth, HELP. :(
Marco knows he has one bacterium per square centimetre. The bacteria population grows and the concentration of bacteria increases by a factor of 10 each day.
1. Find the equation describing the number of bacteria per square centimetre in terms of the time in days.
.. Would the equation be y=1(10)^x?
2. What will the concentration of bacteria be in 3.4 days?
.. How would you go about this?
i inserted the 3.4 as my x, getting 2511.89.
3. When will the concentration be 100 bacteria per square centimetre?
4. When will the concentration be 700 bacteria per square centimetre? Using technology.. How would this differ from 3?
I know it's long, I really need the help.
Thanks guys! Even if you can only answer one part, I truly appreciate it.
