Essential Geometry Terms and Definitions Glossary

A

Acute Angle

An angle measuring less than 90°.

Acute Triangle

A triangle where all three interior angles are acute (less than 90°).

Altitude of a Triangle

A perpendicular segment from a vertex to the opposite side or to a line containing the opposite side.

Angle

It is formed by two rays that share a common endpoint, provided that the two rays are noncollinear.

Angle Bisector

A ray that contains the vertex and divides the angle into two congruent angles.

Arc

Two points on the circle and a continuous part

Quality Management Calculations: EPMO, Control Charts, and Capability

Problem #6-1: 

A bank has set a Standard that mortgage applications be processed within a certain number of days Of filing.  If, out of a sample of 1000 Applications, 75 fail to meet this requirement, what is the epmo metric? 

75 errors per Thousand is equivalent to 75000 epmo. 

Problem #6-2: 

Over the last year, 965 injections were administered at a clinic.  Quality is measured by the proper amount of dosage as well as the Correct drug.  In two instances, the Incorrect amount was given, and

Essential Quality Tools for Process Improvement and Analysis

Quality Tools for Process Control

Quality tools are essential instruments used to control a process, identify faults, improve risk analysis systems, and drive continuous improvement.

Brainstorming

Brainstorming is a technique where a group encourages every member to participate and generate ideas, focusing on quantity over complexity. It is crucial that the group avoids criticizing ideas during the generation phase, as only some ideas will ultimately be valid.

Requirements for Effective Brainstorming

  1. The

Business Profitability: Revenue, Costs, and Break-Even Analysis

Understanding Business Profitability

Profit is the essential difference between a business’s revenue (sales) and its costs. When x units are produced and sold, this relationship can be expressed mathematically:

P(x) = R(x) - C(x)

Profit Calculation Fundamentals

Where:

  • P(x): Represents the total profit derived from the sale of x units.
  • R(x): Represents the total revenue generated from the sale of x units.
  • C(x): Represents the total cost associated with the production and sale of x units.

Revenue Generation

Projectile Motion Analysis: Kinematics and Real-World Applications

Kinematics: Projectile Motion and Relative Velocity

Aim and Background

Aim of Investigation

The aim of this investigation is to analyze projectile motion in two dimensions to understand how the horizontal and vertical components of velocity affect the trajectory, range, and time of flight of a projectile under constant acceleration due to gravity.

Background on Projectile Motion

Projectile motion describes the curved path an object follows when launched into the air, influenced only by gravity and initial
