Given the following rational function:
F(X) = (2X^2 - 20) / [( X - 5 )^2]
Find all horizontal and vertical asymptotes
Find the first derivative of F(X) and simplify
Find the critical values for X and determine if they are at a maximum or minimum, using the First Derivative Sign Test.
Find the Second Derivative and Use it to confirm your answers to part c. You may keep the 2nd derivative in “rough” form and simply substitute in the X value found in part c to see if you confirm a max or a min.

A couple is deciding to invest in the laundromat business. There are two laundromat stores available for sale. They can only afford to buy one of them.
The annual flow of income from each of the available laundromats is given below:
Laundromat 1: I’(t) = dI(t)/dt = 9000e^(.04t)
Laundromat 2: I’(t) = dI(t)/dt = 12500
The couple has decided to use the Present Value of each of the Laundromats after 8 years, at an annual interest rate of 10%, to compare the value of both investments.
They will buy the Laundromat with the highest Present Value.
Find the Present Value of each Laundromat
Which Laundromat should the couple buy? Explain.
Hint: PV(t) = Definite ∫ I’(t)e^(-rt)dt, taken between ( a<t<b)
Here a=0; b=8
r = 10%/100 = .10

1. Dealing with vector fields is very common in engineering and science applications. Vector fields are often used to model a moving fluid throughout space, magnetic or gravitational force, and etc.
a. Provide two examples of vector field for engineering or science applications in two and three dimensions
b. Define a conservative vector field. Verify whether the given examples for vector fields in Part 1(a) are conservative? [15 marks]
c. Interpret the fundamental theorem of line integrals for conservative vector fields. Explain this with an example of a force field (i.e. vector field) and compute the work done by the force field in moving a particle from one point to another point along a curved path in three dimensional space.

Explain how to use derivatives to find the top of a hill or the bottom of a valley on a graph?
What does it even mean for a derivative to not exist and why is this involved? And what does that have to do with a derivative of zero?

A 600-room hotel can rent every one of its rooms at $90 per room. For each $1 increase in rent,
3 fewer rooms are rented. Each rented room costs the hotel $10 to service per day. How much should the hotel charge for each room to maximize its daily profit? What is the maximum daily profit?
