00:01
Okay, so we have a woman that invests $6 ,200.
00:06
So we have $6 ,200.
00:09
And that's going into an account that pays 6 % interest per year, and it's going to be a continuous compound.
00:23
All right.
00:24
So first thing we need to know is continuous compound.
00:26
What is the formula that we use for that? so a continuous compound is going to be the principal times the natural base e to the power our t.
00:37
All right.
00:38
And so we have that information.
00:40
We have our principal amount, which is 6 ,200.
00:43
So that's going to be 6 ,200.
00:46
Okay, times our e.
00:49
And then our rate is 6%.
00:52
And we'll write that as 0 .06.
00:56
So we'll have 0 .06 t.
00:59
Let's change that to our orange.
01:02
Okay.
01:03
So here is our function.
01:06
And this function, is going to allow us to figure out how much money is in the account after so many years.
01:12
Okay, so question number one, we want to know how much is in the account after two years.
01:19
So we're going to start with our 6200, natural base e to the 0 .06, and now we're going to plug in that 2 into t.
01:30
All right, so let's do that now...
