Bacteria is known to grow exponentially. The function `B(h)=82(1.25)^{h}` represents the number of bacteria, B(h), as a function of hours, h. How many bacteria will there be after only 4 hours to the nearest bacteria? What is B(4)?
Show all work.
To find the number of bacteria after 4 hours, we can substitute 4 for h in the function B(h).
B(4) = 82(1.25)^4
B(4) = 82(1.953125)
B(4) = 160.15625
To the nearest bacteria, there will be approximately 160 bacteria after 4 hours.
