If 
is the amount of salt in the tank at time 
, then the rate at which this amount changes over time is given by the ODE
We're told that the tank initially starts with no salt in the water, so
.
Multiply both sides by an integrating factor,
:
Since, we have
so that the amount of salt in the tank over time is given by
After 10 minutes, the amount of salt in the tank is
We're told that the tank initially starts with no salt in the water, so
Multiply both sides by an integrating factor,
Since
so that the amount of salt in the tank over time is given by

Option B
48th term of arithmetic sequence is -152
<h3><u>Solution:</u></h3>Given that a arithmetic sequence has explict formula,
To find: 48th term of the arithmetic sequence
The nth term of arithmetic sequence can be found by substituting the required value of n in the explict formula
So 48th term of the arithmetic sequence can be found by substituting n = 48 in explict formula
Plug in n = 48
On solving we get,
Thus 48th term of arithmetic sequence is -152
