Aparabola is the set of all points that:

a, are the same distance from two lines
b, are the same distance from a point and a line
c, are the same distance from one point
d, are the same distance from two points

Option B is the right answer.

Step-by-step explanation:

A parabola is part of a conic section which is got by cutting a right circular cone by a plane, when the intersection gives rise to an open figure.

A parabola is defined as one conic section with eccentricity 1.

Eccentricity is defined as the ratio of distance of the curve from a line to the distance from a point.

In parabola, the line is the directrix, and the point is the vertex.

And always in a parabola, the distance from the directrix will equal the distance from vertex

Hence option b is right.

Are the same distance from a point and a line.

Step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
