Description
Precalculus is an introductory text. The material is presented at a level intended to prepare students for calculus while also giving them relevant mathematical skills that can be used in other classes.


The authors describe their approach as "Functions First," believing introducing functions first will help students understand new concepts more completely. Each section includes homework exercises, and the answers to most computational questions are included in the text (discussion questions are open-ended). Graphing calculators are used sparingly and only as a tool to enhance the mathematics, not to replace it.

Description
Once upon a time, there was an industry that employed ten-percent of workers worldwide. It spanned borders and cultures, economics, and demographics. It endured man-made catastrophes, natural disasters, economic crises, and technological evolution. It is resilient. It is flexible. It will not rest. Of course, I am referring to the hospitality industry.

Recently, the hospitality industry has faced exceptional adversity in navigating the COVID-19 pandemic. Yet, it has persevered and evolved to continue to provide customers with, although altered, high-quality customer service. Although some players have closed their doors forever, others have adapted to see record growth. The future for hospitality organizations will continue to shift and morph from the world we once knew but it goes without saying that this industry will survive and continue to thrive whatever comes its way.

Join us as we explore the history and future of this diverse and dynamic industry. Each section will show you career paths and real-world success stories in a different segment of the industry. My hope is that your eyes are opened to new opportunities and your passion is ignited to explore how your journey may unfold as a customer, an employee, and, potentially, a leader in the great big world of hospitality.

Description
The Airplane Flying Handbook provides basic knowledge that is essential for pilots. This handbook introduces basic pilot
skills and knowledge that are essential for piloting airplanes. It provides information on transition to other airplanes and the
operation of various airplane systems. It is developed by the Flight Standards Service, Airman Testing Standards Branch,
in cooperation with various aviation educators and industry. This handbook is developed to assist student pilots learning
to fly airplanes. It is also beneficial to pilots who wish to improve their flying proficiency and aeronautical knowledge,
those pilots preparing for additional certificates or ratings, and flight instructors engaged in the instruction of both student
and certificated pilots. It introduces the future pilot to the realm of flight and provides information and guidance in the
performance of procedures and maneuvers required for pilot certification.
