So in this problem were given this table of data which is the viral load bot in this patient.
00:08
T days after a treatment has begun so those tears in days and this viral load is r.
00:22
N.
00:22
A.
00:24
Copies per mr leader.
00:31
Okay.
00:32
And first of all we're asked to find the average rate of change of the respect to the t.
00:37
Over each of these different time intervals.
00:40
The first one is from 4 to 11.
00:44
So the average rate of change abbreviated abbreviated arrow c will be the at 11 minus v.
00:54
At four over 11 miles four.
01:00
Well from the table this is 9.4 -53/7.
01:08
Which yes a- 43.6/11.
01:25
So then we're asked to the interval 8 to 11.
01:31
So the average rate of change here again the 11 minus the eight over 11 -8.
01:42
And so this is 9.4 minus 18 over three.
01:55
And that is a negative 8.6 over three.
02:02
Then we were asked to do from 11 through 15.
02:09
And then average rate of change will be v.
02:13
Of 15 on sv of 11 over 15 -11 which is 5.2 -9.4 over four.
02:29
So that is a negative 4.2 over four.
02:42
Okay and then we're asked to do 11- 22.
02:56
This average rate of change will be the of 22 honest v.
03:03
Of 11 over 22 -11.
03:08
Okay.
03:09
From our table of 3.6...
