So they request that you do this formula, n of t equals the initial amount e to the rt power.
00:08
And so they already tell you in the directions that the initial amount is 1 ,000.
00:12
So what i'm gonna do is plug that in to my formula.
00:16
And they tell you that after one hour, we have a population of 8 ,000.
00:24
So what i need to do is figure out what r is.
00:27
And i can do that by dividing 1 ,000 over, cancels that out.
00:31
And this actually just reduces to eight.
00:33
To undo the e, we're gonna natural log both sides.
00:39
So it's a natural log of eight.
00:42
So i might just tell you to leave your answer like this...
