Title: Formula of a Hydrate. Objective: Determining the percentage of water and the chemical formula of a hydrate. Background: Water has a polar structure and it has positively and negatively charged parts within each molecule. This gives it a strong attraction toward ions. The ions in some salts attract and form strong bonds with water molecules. These salts‚ when they have absorbed water‚ are called hydrates. Anhydrous salts are salts that can form hydrates but which have had all the water

4.4 PAGE REPLACEMENT ALGORITHMS When a page fault occurs‚ the operating system has to choose a page to remove from memory to make room for the page that has to be brought in. If the page to be removed has been modified while in memory‚ it must be rewritten to the disk to bring the disk copy up to date. If‚ however‚ the page has not been changed (e.g.‚ it contains program text)‚ the disk copy is already up to date‚ so no rewrite is needed. The page to be read in just overwrites the page being

Prior to this College Algebra class‚ I have taken algebra 1‚ algebra 2‚ geometry‚ and precalculus. These math classes have allowed me to gain skills and knowledge that I may apply in your class.I learned the concept of factoring in algebra 1. Factoring was a concept that I struggled to understand. It took me several minutes to determine each factor as I was not given a specific way to do it. However‚ in my sophomore year of highschool‚ I was given certain rules and “tricks” to solve equations that

Heron’s Formula History of Mathematics University of Phoenix October 22‚ 2012 The event that I chose to discuss is Heron’s method that was written about in the three book series called metrica discovered in the period of about 60 AD. His formula for calculating the area of a triangle was one of the formulas which was written about in the books. Heron of Alexandria was also very well known by Hero. Their has been much debate on the birth

Six-Gun Mystique. His description of the Western formula being “far easier to define than that of the detective story” may clearly be a paradigm for many authors‚ but not particularly for Stephen Crane. The standards Cawelti has set forth for a successful Western is quite minimal by thought‚ but at the same time relevant. Crane signifies a different perspective to these standards. Crane’s thoughts for the use of the Western formula are just approaches towards the west‚ from the

CHAPTER 2 How to Calculate Present Values Answers to Problem Sets 1. If the discount factor is .507‚ then .507*1.126 = $1 2. 125/139 = .899 3. PV = 374/(1.09)9 = 172.20 4. PV = 432/1.15 + 137/(1.152) + 797/(1.153) = 376 + 104 + 524 = $1‚003 5. FV = 100*1.158 = $305.90 6. NPV = -1‚548 + 138/.09 = -14.67 (cost today plus the present value of the perpetuity) 7.
