7.7 Quadratic Equations and Applications
... When solving applied problems that lead to quadratic equations, we might get a solution that does not satisfy the physical constraints of the problem. For example, if x represents a width and the two solutions of the quadratic equation are 9 and 1, the value 9 must be rejected, since a width must ...

MATH 2113 - Assignment 4 Solutions
... 7.1.3 c) This is not a function since there are two arrows pointing out of ’4’. d) This is a function since every element of X has a unique arrow associated with it. e) This is not a function since it is not defined for all elements of X. There is no arrow associated with ’2’. 7.1.8 - These function ...

Conversion Between Decimal and Binary Representations
... The conversion of a binary number to decimal can be done in two ways: Method 1: Multiply each binary number by its position-value, and add the results together. The rightmost bit has a position value 1, the next 2, the value at the third position is 4, fourth 8 and so on (See figure below) ...

Elementary mathematics
Elementary mathematics consists of mathematics topics frequently taught at the primary or secondary school levels. The most basic topics in elementary mathematics are arithmetic and geometry. Beginning in the last decades of the 20th century, there has been an increased emphasis on problem solving. Elementary mathematics is used in everyday life in such activities as making change, cooking, buying and selling stock, and gambling. It is also an essential first step on the path to understanding science.In secondary school, the main topics in elementary mathematics are algebra and trigonometry. Calculus, even though it is often taught to advanced secondary school students, is usually considered college level mathematics.
