ANSWER

-4.0

EXPLANATION

The given trigonometric equation is

\tan \: 45 \degree - 10 \:  \cos \: 60 \degree

From special angles or using the unit circle.

\tan \: 45 \degree  = 1

\cos \: 60 \degree =  \frac{1}{2}

We make the substitution to get:

1 - 10 ( \frac{1}{2} ))

This simplifies to:

1 - 5 =  - 4

Hence the correct answer is -4.0

If a polynomial function f(x) has roots 4 – 13i and 5, what must be a factor of f(x)?
Morgarella [4.7K]

The factor of f(x) is (x-(4-13i))

If a polynomial function f(x) has roots 4 – 13i and 5

One of the complex roots is 4-13i

If we have one complex root then there should be one more complex root.

<h3>What is the complex root?</h3>

complex roots come in pairs like (a+ib) and  (a-ib)

so another complex root for 4-13i  is 4+13i

If 'a' is a root then the factor is (x-a)

4+13i is a root

So the factor is (x-(4-13i))

Answer:

The possible rational roots are: +1, -1 ,+3, -3, +9, -9

Step-by-step explanation:

The Rational Root Theorem tells us that the possible rational roots of the polynomial are given by all possible quotients formed by factors of the constant term of the polynomial (usually listed as last when written in standard form), divided by possible factors of the polynomial's leading coefficient. And also that we need to consider both the positive and negative forms of such quotients.

So we start noticing that since the leading term of this polynomial is x^3, the leading coefficient is "1", and therefore the list of factors for this is: +1, -1

On the other hand, the constant term of the polynomial is "9", and therefore its factors to consider are: +1, -1 ,+3, -3, +9, -9

Then the quotient of possible factors of the constant term, divided by possible factor of the leading coefficient gives us:

+1, -1 ,+3, -3, +9, -9

And therefore, this is the list of possible roots of the polynomial.
