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
 -----> equation in vertex form
therefore
The vertex is the point (6,-31)
 
        
             
        
        
        
Answer:
17/7
Step-by-step explanation:
2g+2(-8+2g)=1-g
2g-16+4g=1-g
6g-16=1-g
6g-(-g)-16=1
6g+g=1+16
7g=17
g=17/7

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.
 
        
             
        
        
        
Answer:
8
Step-by-step explanation:
Let's call the missing side as x
Base on the pythagorean theorem, we have : 
17² - 15² = x²
289 - 225 = x²
x² = 64
So, x equals 8.
