Question

A colony of bacteria is growing exponentially according to the function below, where t is in hours. what will the approximate number of bacteria after 6 hours? B(t) = (4)(e^0.8t)

a. 122
b. 486
c. 94,251
d. 8602

Answer 1

B

Explanation:

Answer 2

B. 486 bacteria

Explanation:

B(t) = 4 ×
`e^(0.8t)`

When t is equal to 6 hours;

B(t) = 4 ×
`e^(0.8(6))` = 486.0416701 bacteria

i.e 486 bacteria (rounded up to nearest whole number)
