I need this too!!! PLEASE HELPP!!
Answer:
The common difference d in the given sequence is -17
Step-by-step explanation:
We need to find the common difference d of the following sequence 9 -8 -25 -42 -59
We have a₁ = 9
and a₂ = -8
The formula used is:
By putting values we can find the value of d
We have n=2, a₂ = -8, a₁ = 9 and we need to find d
So, the common difference d in the given sequence is -17
Let
denote the amount of salt in the tank at time
. We're given that the tank initially holds
lbs of salt.
The rate at which salt flows in and out of the tank is given by the relation
Find the integrating factor:
Distribute
along both sides of the ODE:
Since
, we get
so that the particular solution for
is
The tank becomes full when the volume of solution in the tank at time
is the same as the total volume of the tank:
at which point the amount of salt in the solution would be
Answer:
the answer is 52
