The number of a certain type of bacteria, y, in a culture is determined by the equation y= 200(4)^x where x is the number of days the culture has been growing. Find the number of bacteria present after 6 days

1 answer

y = 200(4)^x

x = 6 (after 6 days)

y = 200(4)^6

y = 200(4096)

y = 819,200

After 6 days, there are approximately 819,200 bacteria present in the culture.
