**Unit 4**

SAS #1

- Form: Does the graph exhibit a linear or nonlinear pattern?

- Direction: Does the graph exhibit a positive relationship, a negative relationship, or neither

- Relative strength: Are the data points tightly clustered along the line or curve or are they more scattered?

- Variable of interest and study (other ways to analyze data)

SAS #2

SAS #3

Vertical Distance= total distance fallen + total distance risen

SAS #4

Recursive: relating to or involving the repeated application of a rule, definition, or procedure to successive results.

Function Rule: describes the relationship between each input and output.

SAS #7

-Remember the calculator steps

**Unit 5**

**SAS #1**

Job Summary

SAS #2

Savings Accounts: Are insured and vary in the way in which interest is calculated

Certificate of Deposit: is a interest- bearing instrument that is similar to a savings account- it is insured and pays interest

SAS #3

FV= PV(1+1/n)

FV for future value

t for time

i for interest

PV for the present value

SAS #4

FV/(1+i/1)^n+t

FV is future value

t is for time

i is for interest rate

n is for # of compounding periods per year

PV for present value

SAS #5

A cool tool steps

SAS #6

Annuity: Pays out regular payments to investor. Investment increases in value due to compound interest and increase principal.

SAS #8

Daily periodic rate: describes the interest you are paying on your credit everyday

Daily Periodic rate= APR/Day in a year

SAS #10

Buying a Losing Investment

**Unit 7**

SAS #1

Euler Circuits & Paths

Vertex: a point

Degree of a vertex: # of edges that meet at the vertex

SAS #3
