Laws of Exponents and Opposites of Poynomials

1. Using one of the laws of exponents, prove that any number raised to the power 0 is 1. 2. You are given the following polynomial: 2x7 - 4x3 + 3x. If x were replaced with its opposite in each of the terms of the given polynomial, will it result in the opposite of the polynomial? Explain why or why not and illustrate to supp

Finite and Infinite Summations

Explain your answer. See

Sum of 2 nonnegative numbers is 20 Find the numbers

The sum of 2 nonnegative numbers is 20. Find the numbers if: a)if the product of one number and the square root of the other is to be as large as possible, and b)if one number plus the square root of the other is to be as large as possible.

Binary Tree Induction

# Recall that a binary tree can be defined recursively as: * A Binary Tree is either empty * or A Binary Tree consists of a node with a left and right child both of which are Binary Trees. The degree of a node in a tree is equal to 0 if both children are empty, 1 if one of the children are empty, and 2 of both children ar

Grammar Induction

Consider the grammar 1) <Number> -> <Digit><Number>|epsilon 2) <Digit> -> 0|1|2|3|4|5|6|7|8|9 Use induction to show that the number of strings in L(<Number>) of length n is equal to 10^n

Aplication of Algebraic Expressions

Application of Algebraic Expressions

2. Mr. Pinto is a Web designer. He is trying to put 4 characters on a page. The space occupied by character 2 takes 5 units more than character 1, character 3 takes 7 units less than the character 2, and character 4 takes the same space as that taken by character 2. a. Find the total space occupied by all the characters in an a

Translate the following into algebraic expressions. Clearly identify the variables, coefficients, and constants: a) One fourth of one half of the product of two numbers b) Two-thirds of the quotient of two numbers c) The product of 7 and twice n

Variables

Lydia takes ten minutes more to complete an illustration than Tom. The total time taken by both of them is six hours. Form an algebraic equation to express this and identify the variables, coefficients, and constants of the algebraic expression. You are not required to solve the equation.

Measurement of Angles

1. In a certain triangle the measure of one angle is double the measure of a second angle but is 10 degrees less than the measure of the third angle. [The sum of the measures of three interior angles of a triangle is always 180 degrees.] Form an algebraic equation to express the problem and identify the variables, coefficients,

Finite Set of Embeddings

Let E be a finite extension of a field F. Show that any finite set of distinct embeddings of E into the algebraic closure of F is linearly independent over F.

Proof about congruence modulo 43 (also expressible as equivalence modulo 43)

Let S = Z_43 (where the underscore, "_", indicates that what follows it, in this case 43, is a subscript). Let Q be a subset of S that contains ten non-zero numbers (i.e., that Q contains ten non-zero elements of S). Prove that Q contains four distinct numbers "a," "b," "c," "d" such that ab = cd in Z_43.
