Give the name (monomial,
AlladinOne [14]

Answers:

  • Name = monomial
  • Degree = 3

====================================

Explanation:

This is a monomial since it's one term. Terms are separated by a plus sign or minus sign. For instance, the expression 2x^3+5x has two terms.

The expression 12x^3 is a cubic monomial, because the exponent is 3. The degree of the monomial is simply the exponent itself. For polynomials, the degree is the largest exponent. This only applies to single variable polynomials.

A chef has 13 brands of hot sauce. In how many ways can the chef pick 4 to mix into a gumbo. Simplify your answer.
Alex_Xolod [135]

Answer:

715 ways

Step-by-step explanation:

The order in which the brands are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

In this question:

4 from a set of 13. So

C_{13,4} = \frac{13!}{4!(13-4)!} = 715

715 ways
