Instructions and help about Exponential Growth And Death Of Bacteria Worksheet Answer Key

in this video we're going to focus on math problems associated with bacterial growth let's start with this one a petri dish contains 100 counts of bacteria which doubles every three hours part A write a formula that expresses the population as a function of time in hours so there's many ways in which you can write the function you could say the function f of t is equal to a times B racidity there's that form or you could say p of t population is equal to P initial that's the initial population times 1 plus r aised to the T or some variation of that we could use any one of these formulas a is the same as P initial that is the initial amount of bacteria that we have B that is the growth factor which is one plus r and R is the growth rate and T is the time which could be in hours or in minutes I'm going to use this version of the formula so for part A it's going to be P of t is equal to so the initial amount P0 that's a hundred now notice that it doubles every three hours when something d
