2) Compound Interest
$1000 for 3 years at 10% per year compound interest F = P(1 + i)^N = 1000(1 + 0.10)^3 = $1331 | $1000 for one year at 1% per month: $1000(1.01)^12 = $1,126.83 | for one year at 12% annual: $1000(1.12) = 1,120 | at 0.2% per week three years 1000(1.002) 52*3 = 1,365.73 |
2) Bond Valuation
$1000 state govt. bond is issued in 1865. It carries an annual interest rate of 24%. How much is the fair market value of the bond 128 years late in 1993? Compound: 1000(1.24)^128 = 908 T Simple

Best Management Practices
BMPs are non-regulatory, but:
- Failure to apply voluntary BMPs could lead to mandatory forest practice laws later.
- Help maintain “public license.”
Voluntary BMPs are effectively mandatory in many states because of:
- Forest certification (SFI, SFC, Tree Farm)
- Professional certifications (Georgia master timber harvester)
- Tax incentives programs
- Timber sales on public land
- Water quality laws
SMZs:
- Perennial streams: 50 sq ft. basal area and 50% canopy cover.
- Intermittent streams: 25 sq
ANOVA, Chi-Square, and Non-Parametric Statistics: A Comprehensive Guide
Between: each participant goes through a level of the IV. 2-way participants exposed to one level or both IVs, 3-way etc..
Within (repeated measures): all participants exposed to all levels and combinations
1-way ANOVA (1 iv and 1 outcome/dv) : null= means are the same (same as t-test) Exp /omnibus/=they differ
You can manipulate more than one independent variable
and is an extension of t-test.
Pairwise t-tests can’t look at several independent variables
and inflate the Type I error rate. (FW
A Deep Dive into Subspaces, Vector Spaces, and Their Applications in Linear Algebra
What is a Subspace of R^n?
A set U of vectors in R^n is called a subspace of R^n if it satisfies the following properties:
- The zero vector 0-> ∈ U.
- If x-> ∈ U and y-> ∈ U, then x->+y-> ∈ U.
- If x-> ∈ U, then ax-> ∈ U for every real number a.
Any subspace of R^n other than {0} or R^n is called a proper subspace.
Why is a Plane Through the Origin a Subspace of R^3?
Every plane M through the origin in R^3 has equation ax + by + cz = 0 where a, b, and c are not all zero. Here

Determinants and Invertibility
What is the Determinant of a Matrix?
The determinant of a matrix is a scalar value that provides information about the matrix’s invertibility. Only square matrices have determinants.
Calculating Determinants
For a 2×2 matrix A = [a b; c d], the determinant is calculated as det(A) = ad – bc.
For 3×3 matrices and larger, methods like cofactor expansion or row reduction are used.
Determinants and Row Operations
Elementary row operations affect the determinant as follows:

Understanding Asset Management: A Comprehensive Guide
Defining Asset Management
Administration, derived from the Latin terms ad-minister (“to serve”) and ad manus trahere (“to manage”), is crucial for the effective functioning of organizations. It involves the efficient management of both tangible and intangible resources to achieve desired goals. People, money, technology, and even time can be considered resources depending on the context.
The Importance of Resource Management
Effective resource allocation ensures optimal operational efficiency. Various
