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:
40
Step-by-step explanation:
C=(5/9)(104-32)
C=(5/9)(72)
C=40
It is
If you have a slope (which is before the x) then it’s a linear equation
