Question

In the first hour, a culture has 20 bacteria. The bacteria double every hour. Complete the table. Subject: Mathematics Hour Number of Bacteria 2 _____ 3 _____ 5 _____ 6 _____

Answer 1

For the 2nd, 3rd, 5th, and 6th hour, the number of bacteria will be 40, 80, 320, and 640 respectively due to the exponential growth.

Step-by-step explanation:

In this case, the number of bacteria is doubling every hour. So at the 2nd hour, we will have 20 * 2 = 40 bacteria. At the 3rd hour, it again doubles which is 40 * 2 = 80. In the 5th hour, we take the bacteria count from 3rd hour which is 80 and double it twice (for hour 4 and 5) gives us 80 * 2 * 2 = 320. Lastly, in the 6th hour, the bacteria count doubles from the 5th hour resulting in 320 * 2 = 640 bacteria.
