The cross section of a parabolic reflector has a vertical axis of symmetry with its vertex at (0,0) . The focus of the reflector
Paha777 [63]

Answer:

The depth of the reflector is 0.84 feet

Step-by-step explanation:

<em>(See the figure below)</em>

The equation of a parabola centered at the origin with an axis of symmetry on y-axis is:

x^{2}=4py (1)

With p the distance from the origin to the focus using p=6, the equation (1) of the parabola becomes:

x^{2}=4(6)y=24y (2)

Note that the point B is on the parabola, so this point should satisfy the parabola equation (2) that allow us to use the value x=4.5 to find the y value associated to it, that it is the depth (h) of the reflector:

(4.5)^{2}=24y, solving for y

y=\frac{(4.5)^{2}}{24}\approx0.84\,ft
