A pair of listening posts picks up a sound, with one listening post recording the sound after the other. The equation x^2 /1890625 - y^2 / 7,109,375=1 represents possible locations of the sound source with units in feet. How far apart are the listening posts?

In the diagram, points d and e are marked by drawing arcs of equal size centered at b such that the arcs intersect ba and bc. then, intersecting arcs of equal size are drawn centered at points d and e. point p is located at the intersection of these arcs. based on this construction, m , and m

Evaluate this using ! 0.25^2 x 2.4 + 0.25 x 2.4^2 − 0.25 x 2.4 x 0.65
