The equation for the cross section of a parabolic satellite television dish is y = 1/45 x2, measured in inches. how far is the focus from the vertex of the cross section?
the distance from the vertex to the focus is inches.

11.25

Step-by-step explanation:

The equation for a parabola is:

y − k = 1/(4p) (x − h)²

where (h, k) is the vertex and p is the distance from the focus to the vertex.

1/(4p) = 1/45

4p = 45

p = 11.25

The distance from the vertex to the focus is 11.25 inches.

answer: .75 km

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220
