Answer:
The vertex is the point (6,-31)
Step-by-step explanation:
we have
This is a vertical parabola open upward
The vertex represent a minimum
Convert to vertex form
Complete the square
Rewrite as perfect squares
-----> equation in vertex form
therefore
The vertex is the point (6,-31)

Answer:
3 1/8 inches
Step-by-step explanation:
For focus-vertex distance p, the equation of the parabola can be written ...
y = x^2/(4p)
Here, we have p=8. We want to find the value of y when x=10 (the radius of the dish). That is ...
y = (10^2)/(4·8) = 100/32 = 3 1/8
The dish is 3 1/8 inches deep.
