Answer:

Step-by-step explanation:

\frac{y}{a}= tan~60=\sqrt{3} \\y=a\sqrt{3} ~~~(1)\\\frac{y}{b} =tan~30\\y=\frac{b}{\sqrt{3} } ~~~(2)\\from~(1)~and~(2)\\a\sqrt{3} =\frac{b}{\sqrt{3} } \\b=a\sqrt{3} \times\sqrt{3} =3a\\a+b=15\\a+3a=15\\4a=15\\a=\frac{15}{4} \\b=3a=3 \times \frac{15}{4} =\frac{45}{4}\\y=a\sqrt{3} =\frac{15\sqrt{3}}{4} \\\frac{x}{15} =sin~30\\x=15 \times \frac{1}{2}=\frac{15}{2}\\\frac{z}{15}=cos~30\\z=15 \times \frac{\sqrt{3}}{2}=\frac{15\sqrt{3} }{2} \\

Determine whether each expression is a polynomial. If it is a polynomial, find the degree and determine whether it is a monomial
NeX [460]

The question is incomplete. Here is teh complete question.

Determine whether each expression is a polynomial. If it is a polynomial, find the degree and determine whether it is a monomial, binomail or trinomial.

1. 7ab+6b^{2}-2a^{3}

2. 2y-5+3y^{2}

3. 3x^{2}

4. \frac{4m}{3p}

5. 5m^{2}p^{3}+6

6. 5q^{-4}+6q

Answer and Step-by-step explanation: The definition of polynomial is "poly" meaning many and Nominal, which means terms. So, <u>Polynomial</u> is an expression of constants, variables, exponents that are combined using mathematical operators: addition, subtraction, multiplication and division.

However, there are exceptions:

  • Polynomial don't have negative exponent;
  • Polynomial cannot be divided by a variable;
  • Variable cannot be inside a radical;

The <u>degree</u> <u>of</u> <u>a</u> <u>polynomial</u> is the highest exponent of that variable. For example for polynomial 3x^5+6x-5x^{2} , the degree is 5.

Polynomials have 3 different types:

  • monomial: only has one term;
  • binomial: has 2 terms;
  • trinomial: has 3 terms;

Now, analysing each expression given by the alternatives above:

1. It is a polynomial of degree 3 and trinomial.

2. It is a polynomial of degree 2 and trinomial.

3. Yes, its a polynomial of degree 2 and monomial.

4. It is not a polynomial because it is divided by a variable.

5. A polynomial of degree 5 and it's a binomial.

6. It is not a polynomial due to the exponent being negative.
