Answer:
[tex]P=16ft[/tex]
Step-by-step explanation:
From the question we are told that:
Diameter [tex]d=16ft[/tex]
Depth [tex]dp=1ft[/tex]
Generally the equation for a Parabola is mathematically given by
[tex]y=ax^2[/tex]
Since of the parabola has
Diameter [tex]d=16ft[/tex]
Depth [tex]dp=1ft[/tex]
Therefore it passes through
[tex]x=(8,1)[/tex]
Therefore
[tex]1=a(8)^2[/tex]
[tex]a=\frac{1}{64}[/tex]
Since P(distance from focus to the vertex)
[tex]a=\frac{1}{4p}[/tex]
Substituting
[tex]\frac{1}{64}=\frac{1}{4p}[/tex]
[tex]P=16ft[/tex]
