Additional Real World Applications for Radical Expressions
Additional Real World Applications for Radical Expressions Section 5-6 March 2, 2011 Fellow: Brooke Odle Teacher: Ms. Sanchez Saint Vincent Academy Financial Planning A financial planner has been asked to determine the inflation rate for homes. To calculate the inflation of homes that increases from p1 to p2 over n years, the annual rate of inflation (expressed as a decimal) can be modeled as: p2
i p1 1 n 1 Medicine Doctors can approximate the Body Surface Area of an adult (in square meters) using an index called BSA where H is height in
centimeters and W is weight in kilograms: H W BSA 3600 Geology/Meterology/Oceanography The Pacific Tsunami Warning Center is responsible for monitoring earthquakes that could potentially cause tsunamis in the Pacific Ocean. Through measuring the water level and calculating the speed of a tsunami, scientists can predict arrival times of tsunamis. The speed (in meters per second) at which a tsunami moves is determined by the depth d (in meters) of the ocean: g is acceleration due to gravity,
s g d which is 9.8 meters per square second Electrical Engineering To measure voltage (V, measured in volts), electrical engineers use the following formula: V PR Where P is power (measured in watts) and R is resistance (measured in ohms) Physics/Engineering Physicists and engineers may study how force
affects objects. A force is a vector (magnitude and direction) and vectors have components based on direction (x, y, z). To find the total force (resultant force), the following formula can be used: Fy 2 x 2 y Fx 2 z

Supply Chain Management/Business You are a purchasing manager for a medical device company. You are responsible for directing the way the company buys, stores, and sells supplies to other companies. You want to reduce the companys warehousing costs by ordering the supplies needed to produce the medical devices just in time to use them. Supply Chain Management/Business In order to determine the most economic order quantity E for parts used in production of the medical devices, you need to use the following formula: 2* A* S E
I A is the quantity the plant will use in one year S is the cost of setup for making the device I is the cost of holding one unit in stock for one year Find E if S = $6,000, A = 25, and I = $140. Answer: 46 (You cant order a fractional quantity, so round down to 46.)
