Question

3U1: Functions ule 2: Mathematical Modelling on 10: Exponential Function Decay ct #2-Using Logs A bacterial culture triples every P hours. If the culture started with 13000 bacteria and there are 24000 after 2 hours, what is the value of P in hours? (P represents period) If the population of a town changes by an exponential growth factor b every 4 years. If 2350 people grows to 7000 in 3 years, what is the value of b? log A bacteria culture doubles every 5 hours. How long will it take for a culture to quadruple?

did I do it correct.. pls if it's not give me the right answers

Answer 1

Yes, you did it correctly but one mistake is that in the third question that is a bacteria culture doubles every 5 hours; you have written years in the final answer which will be hours. you need to correct that one.
