Answer:

It's is A and D.

Step-by-step explanation:

Tan^2 theta cos 2theta

= (sin^2 theta / cos^2 theta )( 2 cos^2 theta - 1)

= 2 sin^2 theta - sin^2 theta / cos^2 theta

= 2 sin^2 theta - tan^2 theta.

Tan^2 theta cos 2theta

= ( 1 / cot^2 theta) * cos 2theta

= cos 2theta / cot^2 theta.

HELP!!! Use the factor Theorem to determine whether the binomial x+1 is a factor of the polynomial function f(x) =2x^3-9x^2+13x-

Dovator [93]

ANSWER

A. No because f(c)=-30

EXPLANATION

The given polynomial is

$f(x) =2x^3-9x^2+13x-6$

If x+1 is a factor , then f(-1) must evaluate to zero.

$f( - 1) =2( - 1)^3-9( - 1)^2+13( - 1)-6$

$f( - 1) =2( - 1)-9( 1)+13( - 1)-6$

$f( - 1) = - 2-9 - 13-6$

$f( - 1) = -11 - 19$

$f( - 1) = - 30$

Since f(-1) is not equal to zero, x+1 is not a factor of

$f(x) =2x^3-9x^2+13x-6$
