yes, they are all proportional
When a function is reflected, it must be reflected over a line
The new function is: 
The equation is given as:

The rule of reflection over the y-axis is:

So, we have:

Rewrite as:

Hence, the new function is:

We can say that lines A and D are <em>perpendicular</em>.
The tangent function gives the ratio of vertical to horizontal distance in this case.
.. vertical distance = (horizontal distance)*tan(angle of depression)
.. = (40 m)*tan(50°)
.. vertical distance ≈ 47.7 m
Answer:
yes
