Question

Can someone help please!!!!

Answer 1

Answer:

1000 * $3^{9}$ Bacteria after 18 hours,

Step-by-step 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 $\frac{18}{2}$ ties that the bacteria has tripled.

Therefore, the no. of bacteria after 9 hours= 1000 * $3^{9}$
