10) At 9:00 there are exactly 10 bacteria in a dish, and the population doubles every 15 minutes . Pick a time after 10:30 but before 12:00 and determine the number of bacteria in the dish at that time. Show all work supporting your answer.

Respuesta :

Step-by-step explanation:

10 x 2 = 20 (after 15 minutes) 9:15

20 x 2 = 40 (after 30 minutes)

40 x 2 = 80 (after 45 minutes)

80 x 2 = 160 (after 60 minutes) - 10:00

160 x 2 = 320 (after 75 minutes)

320 x 2 = 640 (after 90 minutes)

640 x 2 = 1280 (after 105 minutes) - 10:40

There will be 1280 bacteria in the dish at 10:40.
