Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the equation PV = C, where C is a constant. Suppose that at a certain instant the volume is 900 cm3 , the pressure is 160 kPa, and the pressure is increasing at a rate of 40 kPa/min. At what rate is the volume decreasing at this instant?
---
Step 1: Write all the rates in the problem (including the one you
are trying to find) as
derivatives.
---
Step 2: Identify the dependent variables in the derivatives. Find
an equation relating
the dependent variables in the derivatives. You will often need a
formula from
geometry for this.
----
Step 3: Differentiate both sides of the equation from Step 2 with
respect to the
independent variable time. The result will be an equation relating
the rates (relating the
derivatives).
--
Step 4: Substitute the values that you are given in the problem for
the derivatives and
the variables and solve for the derivative for which the question
is asking.

Thanks for any help!!!

In an RL series circuit with L = 1/100 H, R = 20 Ω, and E = 60 V. Determine the limit of the maximum current reached (At the function you found to determine the current as a function of time apply the limit when t goes to infinity) and determine the time in which it reaches half of that value. Take i (0) = 0 A.

Create your own scenario in which you can compare the cost for two choices for the same service.
You will need to create two equations, each of which should include::
1. fixed cost
2. variable cost
Then write an inequality to compare the two choices and solve it. Interpret your solution to further explain your comparison. Below is an example that you may use as a model to help you develop your own scenario.
I am trying to decide whether to install a solar energy system or replace my existing gas system. The solar system will cost $20,000 to install but only $25 per month. The equation for the total cost is Solar Cost = 25x + 20000 where x is the number of months. The gas system will only cost $5,000 to install but will cost $125 per month. The equation is Gas Cost = 125x + 5000. To find out how long I need to live in my home for the solar to be more cost effective, I need to solve the following inequality: 25x + 20000 < 125x + 5000. When I solve the inequality, x > 150. That means I need to live in the house longer than 150 months, or 12.5 years, for the solar system to be a better deal.

A store sells about 360 calculators peryear. It would cost the store $8 to store one calculator for the whole year. On the other hand, it costs $10 each time the store reorders the calculators, plus $8for each calculator. How many times per year should the store reorderthe calculators and how many at a time to minimize inventory costs?
