Question 1126434: Bacteria are growing in a culture, and their number is increasing at the rate of 5 % an hour . Initially , 400 bacteria are present.
(a) Determine an equation that gives the numbet, N of bacteria present after t hours?
(b) How many bacteria are present after one hour and After four hour? Answer by ikleyn(52781) (Show Source):
a) The equation is N = N(t) = = ,
where t is the time in hours from the starting moment.
b) . . . after one hour ?
To answer this question, substitute t= 1 into the formula and calculate.
. . . after four hours ?
To answer this question, substitute t= 4 into the formula and calculate.
