A pair of listening posts picks up a sound, with one listening post recording the sound after the other. The equation StartFraction x squared Over 1,890,625 EndFraction minus StartFraction y squared Over 7,109,375 EndFraction = 1 represents possible locations of the sound source with units in feet. How far apart are the listening posts? 1,375 ft
2,750 ft
3,000 ft
6,000 ft

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

image result for what is another name for consecutive interior angles? ​

when two lines are crossed by another line (called the transversal): the pairs of angles on one side of the transversal but inside the two lines are called consecutive interior angles. in this example, these are consecutive interior angles: d and f.
