views triple. How many people saw the video on the 7th hour? many total people saw the video after the 7th hour?

Answer 1

10,935 views

Explanation:

We can first design a formula for this scenario. Since the views triple this means that the initial views (i) needs to be multiplied by 3. Since this happens every hour we need to raise 3 to the power of the number of hours (h) that has passed by. This would give us the total number of views at that hour. Therefore, the formula would be the following...

i *
`3^(h)`

We can input the values given to us into the formula and solve it for the total number of view. The initial number of views would be 5 (one for each friend) while we are trying to find the total number of views in the 7th hour.

5 *
`3^(7)`

5 * 2187
