Part 1. Describe the order of operations and explain how it is used to simplify expressions. Explain specifically the order in which mathematical operations must be performed to correctly simplify an expression. The order of operations is a rule that always applies to mathematical problems. It includes addition‚ subtraction‚ multiplication and division as well as grouping of numbers (such as in parentheses and powers). It gives a definite order of how to do a problem involving multiple operations

Chapter 3 Problem 60 Page 133 Dividend yield is the annual dividend per share a company pays divided by the current market price per share expressed as a percentage. A sample of 10 large companies provided the following dividend yield data (The Wall Street Journal‚ January 16‚ 2004). Company | Yield % | Company | Yield % | Altria Group | 5.0 | General Motors | 3.7 | American Express | 0.8 | JP Morgan Chase | 3.5 | Caterpillar | 1.8 | McDonald’s | 1.6 | Eastman Kodak | 1.9 | United Technology

Question 1 Determine the slope for line 2x+12y-6=0 2x+12y=6 12y=-2x+6 y=-2x/12+6/12 y=-x/6+1/2 ∴m=-1/6 Find the slope of the required line‚ which is "m" (-1/6)("m" )=-1 (m)=6 Now‚ substitute m=6 into equation y=mx+c ‚i.e. y=6x+c. This line passed through point (2‚4). So‚ we substitute x=2‚y=4 into y=6x+c. 4=6(2)+c 4-12=c c=-8 ∴ The equation of the straight line that we are looking for is y=6x-8

neurotransmitters somewhere in the central nervous system (CNS) or periphery. In addition‚ certain other body chemicals‚ for example adenosine‚ histamine‚ enkephalins‚ endorphins‚ and epinephrine‚ have neurotransmitter-like properties‚ and many additional true neurotransmitters may await discovery.

Mathematics and religion are two very different concepts. Scientist and Theologians have had conflicts involving the two that are usually based off of an argument that encompasses logic versus faith. However‚ using reason‚ we can come to the conclusion that it is possible for both mathematics and reason to have many different similarities. Mathematics relies on reason and logic. Although Mathematics is based off of axioms that are rarely questioned‚ we still need to justify our methods and answers

DISCRETE MATHEMATICS Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly"‚ the objects studied in discrete mathematics – such as integers‚ graphs‚ and statements in logic – do not vary smoothly in this way‚ but have distinct‚ separated values. Discrete mathematics therefore excludes topics in "continuous mathematics" such as calculus and analysis. Discrete objects
