The number of bacteria in a colony is growing exponentially. A scientist notes that the number of bacteria in the colony is 50. Two hours later, she notes that the number of bacteria has increased to 80. If this rate of growth continues, how much more time will it take for the number of bacteria to reach 100?

stops on an even number.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
