WebTo find r, use the fact that after one hour (t = 1) the population doubles from 10 to 20. The formula is derived as follows. 20 = 10er ⋅ 1 2 = er Divide by 10 ln2 = r Convert to exponential form. so r = ln(2). Thus the equation that models the bacteria growth is N(t) = 10e ( ln 2) t = 10(eln 2)t = 10 · 2t.
