Question

Can someone help please!!!!

Answer 1

1000 *
`3^(9)` Bacteria after 18 hours,

Explanation:

The condition given in the problem is that the number of bacterial triple after every 2 hours.

So, after 2 hours, total bacteria= 1000 * 3

So, after 4 hours, total bacteria= 1000 * 3 * 3

Therefore, the general format for the number of bacteria is 1000 *
`3^(n)`, where n is the number of times the bacteria has tripled.

In 18 hours, there are
`(18)/(2)` ties that the bacteria has tripled.

Therefore, the no. of bacteria after 9 hours= 1000 *
`3^(9)`
