The number of bacteria present in a culture is given by N(t) = 15,000(3t), where N(t) is the number of bacteri

The number of bacteria present in a culture is given by N(t) = 15,000(3t), where N(t) is the number of bacteria after t hours. Find the number of bacteria present after 6 hours.

The number of bacteria present in a culture is given by N(t) = 15,000(3t), where N(t) is the number of bacteri
N(6) = 15 000 (3(6))





=15 000 * 18





=270 000
Reply:This is a problem of substitution. Where ever t is, place 6.





N(6) = 15000(3*6) = 15000(18) = 270000 bacteria present.
Reply:N(t) = 15,000(3t)


t = 6 hours


N(6) = 15,000(3*6)


N(6) = 15,000(18)


N(6) = 270,000 bacteria
Reply:N(t) = 15,000(3t)


Since time is 6 hours, N(t) = 15,000(3 x 6)


= 15,000 x 18


= 270,000 numbers of Bacteria present after 6 hours.
