Question: (a) Bacterial growth can be modelled using an exponential growth formula, = 0 kt Where y is the number of bacteria present after t hours

(a) Bacterial growth can be modelled using an exponential growth formula,

= ₀^kt

Where y is the number of bacteria present after t hours have passed and N0 represents the initial number of bacteria present.

100 bacteria are plated out onto agar at t = 0 hours. Five hours later there are 300 bacteria present. Calculate the growth constant k for this bacteria species. Give your answer to two decimal places and show all working.
