Answer:

10*sin(40)=AC

Step-by-step explanation:

sin(x)=\frac{opposite}{hypotenuse}

so

here it says

sin(40)=\frac{AC}{10}  multiply both sides by 10

10*sin(40)=AC

What are the zeros of the polynomial function? f(x)=x3+2x2−x−2 Select each correct answer. A.−3 B. −2 C. −1D. 0 E. 1F. 2 G. 3
LenaWriter [7]

Answer:

B. −2

C. −1

E.  1

Step-by-step explanation:

He have been given a polynomial function f(x)=x^3+2x^2-x-2. We are asked to find the zeros of our given function.

To find the zeros of our given function, we will equate our function with zero and solve for x as:

x^3+2x^2-x-2=0

Now, we will factor our equation by grouping method.

(x^3+2x^2)-(x+2)=0

x^2(x+2)-1(x+2)=0

(x+2)(x^2-1)=0

Now, we will use difference of squares a^b-b^2=(a+b)(a-b)

(x+2)(x^2-1^2)=0

(x+2)(x+1)(x-1)=0

Using zero product property, we will get:

(x+2)=0\text{ or }(x+1)=0\text{ or }(x-1)=0

x=-2\text{ or }x=-1\text{ or }x=1

Since the zeros of our given function are -2,-1\text{ and }1, therefore, options B, C and E are correct choices.
