Determine XY
To solve for XY, we make use of the tan function, which states that:
tan\theta = \frac{Opposite}{Hypotenuse}tanθ=
Hypotenuse
Opposite
In this case:
tan\ 60= \frac{YZ}{XY}tan 60=
XY
YZ
Substitute 4 for YZ
tan\ 60= \frac{4}{XY}tan 60=
XY
4
Make XY the subject
XY= \frac{4}{tan\ 60}XY=
tan 60
4
tan\ 60 =\sqrt 3tan 60=
3
So, the expression becomes:
XY = \frac{4}{\sqrt 3}XY=

Rationalize:
XY = \frac{4 * \sqrt 3}{\sqrt 3 * \sqrt 3}XY=

Answer:
The given function 
was replaced with 
then the value of k is -3
that is k=-3.
Step-by-step explanation:
The given function is 
and when x=x+k then 
Now to find the value of k:
Put x=x+k in the function f(x)
Now comparing equations (2) and (3) we get
Therefore k=-3
Therefore the given function was replaced with then the value of k is -3
that is k=-3.
