"What Is The Meaning Of A In Mathmatical Terms"

What is the meaning of A in mathmatical terms

 

Answer:

In set theory, A refers to elements of universal set not included in Set A.

A is read as complement of Set A.

Example:

Universal Set = {a, b, c, d, e, f, g}

A = {a, c, e, g}

A = {b, d, f}   ⇒  the elements not in Set A.

Another example:

Universal Set = {a, b, c, d, e, f, g}

A =  {a, b, c, d, e, f, g}

A = ∅   ⇒  null or empty set since all elements are included in Set A.

Write True If The Statement Is True. Otherwise, Modify The Underlined Word(S) To Make It True. 2. Every Polynomial Equation Of Degree N Has N 2013 1 R

Write TRUE if the statement is true. Otherwise, modify the underlined word(s) to make it true. 2. Every polynomial equation of degree n has n – 1 real roots.   Polynomial Equation:         "Every polynomial equation of degree n has n - 1 real roots." This statement is false and in order to make it a true statement it should be... "every polynomial equation of degree n has at most n real roots" which is a consequence of the Fundamental Theorem of Algebra.     Definition:        A polynomial equation is any polynomial equated to zero . Examples: x - 2 = 0 x² + 2x + 5 = 0 5x + 1 = 0 x³  - 2x² - 4x + 8 = 0 x(x - 4) = 0 Explanation:   x - 2 = 0 the number of root(s) is just 1 since it is a polynomial of the first degree. x² + 2x + 5 = 0 the number of root(s) is 2 since it is a polynomial of the second degree. 5x + 1 = 0, there is only 1 root because it is a polynomial equation of the first degree. x³  - 2x² - 4x + 8 = 0 have 3 roots since its high...

Which Of The Following Is The Factored Form Of X^3 + 3x^2 2013 10x 2013 24?, A. (X + 4)(X 2013 3)(X + 2) , B. (X 2013 4)(X 2013 3)(X 2013 2) , C. (X 2

Which of the following is the factored form of x^3 + 3x^2 – 10x – 24? a. (x + 4)(x – 3)(x + 2) b. (x – 4)(x – 3)(x – 2) c. (x – 4)(x – 3)(x + 2) d. (x + 4)(x + 3)(x – 2)   Factoring Polynomials: Listing Method: The factored form of x³ + 3x² – 10x – 24 is (x + 4)(x – 3)(x + 2). Solution: List all the possible factors of the first term.        x³ = (x)(x)(x)    2. List all the possible factors of the last term.        -24 = (1)(-24); (-1)(24); (2)(-12); (-2)(12); (3)(-8); (-3)(8); (4)(-6); (-4)(6)    3. From the list above, form the factors. Make sure that the 3 factors of          -24 will have a sum of -10 which is the middle term of the given         polynomial.         (x + 2)(x – 3)(x + 4)       4.
