The correct answer is the option "B":
B.(-x-6i)(x-6i)
Explanation
You must keep in mind the following:
1. By definition, a complex number has the following form:
a+bi
"a" is the real part and "b" is the imaginary part.
2. i²=-1
3. Then,you have:
(-x-6i)(x-6i)=(-x²+(6i)²)=-x²-36
4. Therefore, the answer is: (-x-6i)(x-6i)
The answer is: Chord.
I just had this exact question on an exam.

Answer:
No. The reciprocal of a function is rarely the same as the inverse of the function.
Step-by-step explanation:
tan^1(a) signifies the arctangent function, the function that returns the angle for a given tangent value of a.
tan(a)^-1 signifies the reciprocal of the tangent function, which is the definition of the cotangent function.
The attached graph compares the two functions.
The first step for finding y is to divide both sides of the equation by 9.
9y ÷ 9 = 2x ÷ 9
When dividing 9 by 9 you must remember that any expression divided by itself equals 1.
y = 2x ÷ 9
Now write 2 ÷ 9 as a fraction.
y =

x
This means that the answer to your question is that y =

x.
