We're given an equation for the amount of medication in the bloodstream, and we're told that it decreases with time.
00:25
We're told that a sub 0 is 100 cubic centimeters.
00:33
We need to find a of 0127 and 10.
00:41
So i'm going to make a table.
00:59
Okay.
01:03
So, for example, i'm going to put in a of zero is 100 cubic centimeters over t squared plus 1, where t is 0.
01:24
Well, 100 divided by 1 is 100.
01:30
And that makes sense because initially all of it is in the bloodstream.
01:36
Okay, if i put in a 1, 1 squared is 1, 1 plus 1 is 2, 100 divided by 2 is 50.
01:44
If i put in a 2, 2 squared is 4 plus 1 is 5, 100 divided by 5 is 20.
01:53
If i put in a 7, 7 squared is 49 plus 1 is 50.
01:58
100 divided by 50 is 2.
02:02
And if i put in a 10, 10 squared is 100 plus 1 is 101...
