basic elements of a program

Objective Function: The Objective Function is a linear function of variables which is to be optimised i.e., maximised or minimised. e.g., profit function, cost function etc. The objective function may be expressed as a linear expression. Constraints: A linear equation represents a s..

Set: A well-defined collection of distinct objects is called a set. Notation of Sets: Capital letters are usually used to denote or represent a set. Representation of Sets: There are two methods of representing a set. (i) Roster Method (ii) Set builder form. Finite an..

Basic oxides are the oxides of metals. If soluble in water they react with water to produce hydroxides (alkalies) e.g., ..

Symbol C Atomic number 6 Mass number 12 Isotopes 12 6 C, 13 6 C, 14 6 C 1. Carbon is the first member of the group IVA. 2. Electronic configuration of this group shows that the members have four electrons in their valence shell. 3. Other members of this group ar..

Conclusion - The graphical method of solving an LPP is possible only if there are two decision variables (say x and y). This method is not suitable if there are three or more decision variables. In this case, there is a powerful method called 'simplex method'. The wide usage of liner programmi..

Question 1 - Question: List the elements of the following sets. Answer: i) Omit o and u from the vowels a, e, i, o, u to get {a,e,i} ii) There are exactly two such names {Karnataka, Keral..

Symbol N Atomic Number 7 Electronic Configuration 2,5 Formula N 2 Relative Atomic Mass 14 Relative Molecular Mass 28 Vapor Density 14 Valency 1, 2, 3, 4, 5 ..

Some Basic Features of Chlorine - Symbol Cl Formula cl2 Atomic number 17 Electronic configuration 2, 8, 7 Valency -1 Relative Atomic Mass 35.5 Relative Molecular Mass 71 Vapor Density 35.5 Isotopes 35 37 Cl , Cl17 ..

Almost all the elements of group 13 form oxides and hydroxides of the composition M 2 O 3 and M(OH) 3 respectively. The nature of these oxides / hydroxides change from weakly acidic to amphoteric and amphoteric to basic in moving down the group from B to Tl...
