MAT 101M: Mathematics for the 21st Century
Fall 2018
Exam 2 information
1. Notes and materials
You are permitted one letter-size handwritten notes sheet (both sides) for use as a reference during the exam.
Be sure you have your own scientific calculator (or graphing calculator) to use during the exam. You may want to bring spare batteries.
2. How to study
Please see tips from last exam.
Practicing by solving problems is much more effective than reading over solutions. There are concept review questions in each set of exercises in the textbook. Going over homework and quiz correcting mistakes is also a good idea.
3. Exam content
The exam covers everything we have done, up to and including Section 9C. While the exam is cumulative, we will focus on what was not already tested. Here are some topics we emphasized since the last exam:- budgeting and cash flow
- simple interest
- compound interest
- Rule of 70
- APY
- savings plan
- total / annual return
- investments: liquidity, risk, return
- installment loan
- home ownership: equity, points, down payment, etc.
- linear growth / decay
- exponential growth / decay
- doubling time, half life: estimate via Rule of 70 and exact via logarithms
- logistic growth
- exponential modeling
As usual, please note that this document is not a contract. I may have inadvertently left something off that ends up on an exam question. Moreover, I will not be able to test all of this material given the time limitations of the exam. I will have to pick and choose some subset of it.
