Question

If ten bacteria landed on bowl of soup and reproduce every 30 seconds how many would be present after 1 hour?

Answer 1

Answer:

WE CAN USE GEOMETRIC PROGRESSION

HERE BECAUSE

30 SECONDS 20 ORG

1 MINUTE 40 ORG 1.30 MINUTE 80 BACTERIA

GEOMETRIC PROGRESSION a r^n-1

a is 10 and r is 2 and n= 121

so 10×2^120
