Question:An architect designs two houses that are shaped and positioned like a part of the branches of the hyperbola whose equation is 625y^2 - 400x^2=250‚000‚ where x and y are in yards. How far apart are the houses at their closeset point? Answers:625y^2 - 400x^2=250‚000 y^2 / 20^2 - x^2 / 25^2 = 1 The closest two points on separate branches are the vertices‚ and their separation is 2 * 20 = 40yd. I find the question a little confusing‚ though. Question:LORAN (long distance radio navigation)

Studying artifacts is like looking through a keyhole into the past. Although artifacts themselves cannot speak‚ a lot can be learned from studying primary documents and artifacts. For thousands of years‚ historians have been using primary documents and artifacts to make inferences about the people‚ places‚ and events that surrounded the time period. In our study of the Rixford Cemetry‚ we were able to use primary documents and artifacts to make analyses about the surrounding area. There are many

Ian Brown compels readers with his memoir of the challenges and rewards that come with raising a child with (dis)abilities. Brown provides evidence into the ramifications of ableism and the negative socio-cultural construction of (dis) ability‚ on top of‚ the inadequate support available. The compounding oppressions after exposure for an extended period create damaging psychological effects (Mullaly‚ 2007). Many of the economic‚ political‚ and social barriers the Brown’s encounter are due to ableism

SUSPENDED SOLIDS 1.0 OBJECTIVE This objective of this experiment is to determine the quantity of suspended solids in polluted water samples. 2.0 INTRODUCTION Water quality is vitally important in our daily life. However‚ due to water pollution‚ the quality of water is questionable for safe usage. In order to determine water quality‚ one of the indicator and measurement that can be used is by suspended solids (SS). Suspended solids is one type of physical water-quality measurement. Suspended solids refer

Solid Waste Management Sci/275 Shannon Johnson 08/21/10 Shannon Gumtau The terrestrial resource I chose was solid waste. The EPA defines solid waste as “any garbage or refuse‚ sludge from a wastewater treatment plant‚ water supply treatment plant‚ or air pollution control facility and other discarded material‚ including solid‚ liquid‚ semi-solid‚ or contained gaseous material resulting from industrial‚ commercial‚ mining‚ and agricultural operations‚ and from community activities.

March 2‚ 2011 Lab Report Physical Properties of Two Types of Solids SCH3U0 Maggie Liu Abstract The purpose of this lab is to study some of the physical properties of two types of solids – ionic and molecular. The samples used are sodium chloride (ionic) and camphor (molecular). The physical properties studied are odour‚ hardness‚ melting point‚ solubility in water and solubility in 2-propanol. It is observed that some of the physical properties of sodium chloride are no odours‚ hard‚ a

C OORDINATE GEOMETRY COORDINATE GEOMETRY 155 7 7.1 Introduction In Class IX‚ you have studied that to locate the position of a point on a plane‚ we require a pair of coordinate axes. The distance of a point from the y-axis is called its x-coordinate‚ or abscissa. The distance of a point from the x-axis is called its y-coordinate‚ or ordinate. The coordinates of a point on the x-axis are of the form (x‚ 0)‚ and of a point on the y-axis are of the form (0‚ y). Here is a play for you. Draw a set

encompasses 7‚107 islands‚ though only about 2‚000 islands are currently inhabited. With a rapidly growing population and lack of adequate disposal sites‚ solid waste has become a major problem for most medium to large – size cities. When Philippine President Gloria Macapagal – Arroyo took office in January 2001‚ the first act she signed into law dealt with solid waste management systems have posed serious health risk particularly in densely populated areas. In Manila‚ for example‚ the closure of the largest

Is glass a solid or a liquid "The idea that glass is a fluid is a very widespread myth." (Yvonne Stokes:1999‚Discover Magazine) This myth has survived for centuries because glass is such a confusing matter which cannot be compared to the three ordinary kinds of matter described in our particle theory of matter. Gasses contain free flowing molecules which are much further apart then liquids and gasses which removes the possibility of glass being a gas. A liquid however contains tighter bound molecules
