Answer:
a
b
c
Step-by-step explanation:
From the question we are told that
Now integrating both sides
Now taking the exponent of both sides
=>
Let
So
Now from the question we are told that
Hence
=>
So
From the question we are told that
substituting for y
=>
Now integrating both sides
Now taking the exponent of both sides
=>
Let
=>
Now from the question we are told that
So
=>
divide both side by
=>
So
=>
=>
Generally as t tends to infinity , tends to zero
so
