Answer 2

I'm not exactly sure what the heck a feedhorn is at all. I've never heard of it. What I do know is that this is a y^2 parabola that opens up to the right. In standard form it is \[y ^{2}=44x\]and it will have a focus at (11,0). I bet that 11 is the answer. Can you try it and see if it is correct?
