Correct answers only a population of bacteria is growing according to the exponential model p = 100e^(.70)t, where p is the number of colonies and t is measured in hours. after how many hours will 300 colonies be present? [round answer to the nearest tenth.]

B

Step-by-step explanation:

1.6 = t

Option B. 1.6 Hours

Step-by-step explanation:

The model for the population of bacteria is growing by :

Where P = Number of colonies

and t = time in hours.

So, now put  the value of  P = 300 in the given model and obtain the value of t.

⇒

⇒

Taking the natural log in on both the side

⇒

⇒

⇒

⇒ t = 1.6 hours

Therefore, The correct option is B). 1.6 hours
