We are given zeros of the polynomial : 7, -11, and 2 + 8i.
Note: The radical zero always comes with the pair of plus and minus sign.
Therefore, another zero would be 2-8i.
Now, in order to find the polynomial with the zeros 7, -11, 2 + 8i and 2-8i, we need to find the factors of the polynomial.
The factors of the polynomial would be (x-7)(x+11)(x-2-8i)(x-2+8i).
Let us multiply those factors to get the standard form of the polynomial.

Answer:
What's the line?
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
<u>This is a right triangle as shown by the right angle.</u>
- The side opposite the right angle is the hypotenuse, which is 9.
- The side opposite angle A is 3.
So we have the opposite of A and the hypotenuse.
The trigonometric ratio that relates opposite side to hypotenuse is SINE.

Since, we need angle A,
is A, opposite side is 3, and hypotenuse is 9, we substitute:

<em>To solve for the angle, we use our calculator and find the inverse sin of
:</em>

<em>Rounding to nearest tenth of a degree:</em>

B is the right choice.
Answer:
step by step below.
Step-by-step explanation:
after subtracting the 2x, youd have 3x on the right side. and they you would want to get the numbers on one side, so subract the 3 to the left side. and then you would have -11.

solve for x if necessary
Answer:
(C) 90 
Step-by-step explanation:
The figure is a combination of two parallelograms. So, to find the area of the whole figure, all you have to do is find the area of each parallelogram separately (they happen to be the same in this problem) and then add them up. The formula for the area of a parallelogram is <u>A = base*height</u>. In each parallelogram, the base is 15 in., and the height is 3 in. Therefore, the area of each parallelogram is 45
and the area of the whole figure is 90
