Hi, today we are solving the question in which concentration c, t is equals to 20 by 20 into t by t square plus 4.
00:12
So let it consider to be equation first.
00:16
Now, firstly, we need to determine when the concentration will be 0 .5.
00:22
So simply putting c t as 0 .5 in the above equation.
00:27
So it will be 0 .5 is equal to 20 t by t square plus 4.
00:35
So from here on solving it, we get it as equals to t square, t will be equal to 39 .8 hours.
00:47
So from here we can conclude that therefore t is equals to 39 .8 hours.
00:55
Now we are given that we need to complete the.
00:59
Given table so on putting the value as taking second so t is equals to zero in the formula we get c not is equals to 20 into 0 by 0 square plus folded will become equal to zero so similarly t will 1 then c1 will be equal to we have to take not 1 it is taken as 2 so c2 will be equal to 5 then taking t as 4.
01:36
So c4 will be 4.
01:41
Then 6t.
01:43
Then c 6 will be given as 3.
01:51
Then taking t is equal to 8.
01:55
So c 8 will be 2 .35.
02:02
Now taking t is equal to 12...
