Answer/step-by-step explanation
The soldier at point P lie on a parabola because he determined his position and distances from towns A and B through measurement of the difference in timing (phase) of radio signals received from the two towns.
This analysis of the signal time difference gives the difference in distance of the soldier at P, from the towns.
This process is known as hyperbolic navigation.
These distances of point P from towns A and B is estimated by the soldier at point P, by measuring the delay localizes the receiver to a hyperbolic line on a chart.
Two hyperbolic lines will be drawn by taking timing measurements from the
towns A and B .
Point P will be at the intersection of the lines.
These distances of point P(The soldier's positions) from town A and town B were determined using the timing of the signals received from the two towns, due to the fact that point P was on a certain hyperbola.
Y = -1/2x - 1

The standard form of this equation is
The slope of two parallel lines i the same, so the slope of the line we're looking for is also
Since the line passes through
, the equation is:
She has to score at least 86 on her fifth test.
Further explanation:
We will use the average formula to find the fifth value.
Given
We have to find x5
The formula for average is:
She has to score at least 86 on her fifth test.
