Answer:
Step-by-step explanation:To find the number of bacteria after 2 hours, we can use the formula for exponential growth:
Nt=N0×(1+r)t
Where:
Nt= the final number of bacteria after time tt
N0 = the initial number of bacteria
r = the growth rate (expressed as a decimal)
t = the time in hours
Given:
N0=4×106 (initial number of bacteria)
r=10%=0.10 (growth rate per hour)
t=2t=2 hours
Substitute these values into the formula:
Nt=4×10^6×(1+0.10)^2
Nt=4×10^6×1.21
Nt=4.84×10^6
So, after 2 hours, the number of bacteria will be 4.84×10^6.
