._., idk u tell me?

Answer 10

To solve the equation of the parabola, I would need to use the distance formula and substitute the focal point in (x1-y1). Also use the distance formula for the directrix. Since it is a straight line, the x part could be eliminated and the remaining part of the formula would be used, substituting the y for the given measurement of the directrix. The two unfinished formulas would be combined and then solve for the equation. f(x) would be the unit of measurement for parabola.

Answer 11

how do I make this directly answer the question better? got it wrong

Answer 12

no clue :/

Answer 13

Please kindly help @jim_thompson5910

Answer 14

"An archway will be constructed over a walkway"

so we know that the parabola opens downward and might look something like this

Answer 15

The focus is always on the inside of the curve with the directrix on the other side of the parabola
