Your employer automatically puts 5 percent of your salary into a 401(k) retirement account each year. The
account earns 8% interest. Suppose you just got the job, your starting salary is $40000, and you expect to
receive a 2% raise each year.
For simplicity, assume that interest earned and your raises are given as nominal rates and compound
continuously.
Find the value of your retirement account after 30 years
Value = $
Suppose that a room containing 1300 cubic feet of air is originally free of carbon monoxide (CO). Beginning
at time t = 0, cigarette smoke containing 4% CO is introduced into the room at a rate of 0.8 cubic feet per
minute. The well-circulated smoke and air mixture is allowed to leave the room at the same rate.
Let A(t) represent the amount of CO in the room (in cubic feet) after t minutes.
(A) Write the DE model for the time rate of change of CO in the room. Also state the initial condition.
dA
dt
A(0)
(B) Solve the IVP to find the amount of CO in the room at any time t > 0.
A(t)
(C) Extended exposure to a CO concentration as low as 0.00012 is harmful to the human body. Find the time
at which this concentration is reached.

Newton's Law of Cooling tells us that the rate of change of the temperature of an object is proportional to
the temperature difference between the object and its surroundings. This can be modeled by the
differential equation
dT
dt
k(TA), where T is the temperature of the object after t units of time
have passed, A is the ambient temperature of the object's surroundings, and k is a constant of
proportionality.
Suppose that a cup of coffee begins at 178 degrees and, after sitting in room temperature of 61 degrees
