Answer:

x<10

Step-by-step explanation:

To solve this problem, add 8 from both sides and divide by 2 from both sides.

2x-8+8<12+8

2x<20

2x/2<20/2

20/2=10

x<10 is the correct answers.

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.

What are the focus and directrix of the parabola with the equation y=1/16x^2

Vlada [557]

Y=1/16x^2
multiplying both sides by 16 we get:
16y=x^2
The general form of a parabola is:
(x-h)^2=4p(y-k)
thus
4p=16
p=4
The parabola opens upwrd:
Focus: (h,k-p)
(0,0-4)
=(0,-4)
Directrix: y=-4
