The very first part of this is going through an identifying a, b, and t.
00:04
So the a value is the initial amount, as always.
00:06
So 50 is our initial amount that we're starting with.
00:09
The b value is the base of the exponential piece here, so that's the one -half.
00:13
And the t -value, not c, the t -value is the denominator of the fraction that's in the exponent.
00:19
So that's going to be six.
00:20
So what does this actually mean? well, we're going to take that 50, and it's going to be cut in half.
00:27
So we can say it's half -life.
00:28
So the half life of whatever this is.
00:32
So half life is six years.
00:36
So every six years is cut in half.
00:38
So for the second part there, what it wants to know is the growth rate itself...
