Answer:
The depth of the reflector is 700 feet.
Step-by-step explanation:
The cross section of a parabolic reflector is just a parabola (see the figure below). Because it has a vertical axis of symmetry and its vertex is at (0,0) the equation of the parabola is:
With p the distance to the focus (p=6ft), the equation for our particular case is:
Note that because the reflector extends 5.5 feet to either side of the vertex, the extreme sides of the parabola are on the curve so they satisfy our parabola equation (3). Let’s concentrate on the right extreme of our parabola with x-position 5.5 ft using this number on (3) equation we can find the respective y-position
and that correspond to the depth of the parabolic reflector.

<u>Given</u> -
- A rectangular bathroom mirror is 4 feet tall and 7 feet wide.
ie, length of the mirror, L = 4 feet and breadth of the mirror, B = 7 feet .
<u>To find</u> -
<u>Solution</u> -
As we know to find the area of rectangle we use the formula, Area = L × B
Hence, we will be doing the same.
Area = 4 × 7
Area = 28 square feet
