Math150 College Algebra Ctu Phase 1 Db2

MATH150-1201A-01 Phase 1 DB2 Part 1 and Part 2-Primary Task receipt January, 2012 Part 1 Confirmation of MyLabsPlus login I was able to login to MyLabsPlus with my username and password. Part 2 Primary Task Response 1. I went into the learning lab and in the mathematics section I chose the introduction titled Basic Algebra Skills-Real metrical composition &038 Algebraic Equations, Exponents &038 Scientific Notation, Radicals &038 Radical Exponents, and Polynomials. I chose this presentation because I entangle I needed to remember algebraic comparisons, exponents and polynomials. I have non had algebra for some years so this presentation was a very nice refresher.It reminded me about unfeigned turnings and algebraic verbiages and public square roots. It was good to be reminded about the steps you take in algebra to solve an equation such(prenominal) as 1. Perform operations within the innermost parenthesis primary and workings outward. 2. Evaluate all exponential expressi ons. 3. Perform multiplications and divisions as they occur, working from left to right. 4. Perform additions and subtractions as they occur, working from left to right. Overall the presentation was a very good reminder. I am happy I watched this particular presentation.I definitely will benefit by see the learning lab math center because I have not had algebra in many years and I will need the unornamented help to learn. 2. I would pardon to the programmers in my new job that a mathematical expression is a phrase or a conviction fragment with a variable that has to be simplified and has no copulation symbol. And that a mathematical equation is a sentence that you solve and has a relation symbol and is a statement that two numbers or expressions are equal. A couple of mathematical physical exercises of the difference between an expression and an equation is 1. Mathematical expression 1. z + 2 ? (7 z) 2.A number is less than five. x < 10. 2. Mathematical equation 1. 6 =6 2 . 15 = 2 + 13 A real life example of when mortal would use a mathematical expression is when a car is dismission a certain mph speed and the driver wants to know how many miles he has traveled after so many hours. A real life example of when someone would use a mathematical equation would be to figure their profit or loss during months of business. 3. I would explain to the programmer that the expression means five x five x five = 125 and not 5 x 3. I would explain that 5 is the base and 3 is the exponent or power. I would show him/her how to calculate it on paper.A real life example where one would use exponents is when one would need to measure square feet, square kilometers or square inches. You might also use it if you need extremely tiny or extremely big quantity results. References Math fusion Press, (copyright, 1997-2006). Introduction to algebra.
