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:
Explanation: L = longer piece S = shorter piece
L + S = 22
L = 4 + S
S + S + 4 = 22
-4 -4
S + S = 18
S = 18/2 = 9 cm
L = 4 + S —> 4 + 9 = 13 cm
To confirm:
13 cm + 9 cm = 22 cm
Therefore, the shorter piece is 9 cm.
Answer:
r <5
Step-by-step explanation:
r-4<1
Add 4 to each side
r-4+4<1+4
r <5
