A bacteria culture starts with `420` bacteria and grows at a rate
proportional to its size. After `2` hours there will be `840` bacteria.
(a) Express the population `P` after `t` hours as a function of `t`. Be sure to keep at least 4 significant figures on the growth rate.
`P(t)`=
(b) What will be the population after 3 hours?
bacteria
(c) How long will it take for the population to reach 1030? Give your answer accurate to at least 2 decimal places.
hours
Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
