hoa [83]

Answer:

(i) Distance of point P from x-axis is 3 units.

(ii) Distance of point P from y-axis is 2 units.

(iii) Distance of point P from z-axis is 7 units.

Step-by-step explanation:

Given points is P(3, −2, 7).

Coordinate plane is a plane containing both x-axis and y-axis.

x-axis is the horizontal line and y-axis is the vertical line.

The axes divide the coordinate plane divide into four quadrants.

The axes are perpendicular to each other.

To find:distance of point P from (i) x−axis, (ii) y−axis, (iii) z−axis

Solution:

(i) Distance of point P from x-axis is 3 units.

(ii) Distance of point P from y-axis is 2 units.

(iii) Distance of point P from z-axis is 7 units.

An army base in the desert is located at the origin, O of an x-y coordinate system. A soldier at point P needs to determine his

Nutka1998 [239]

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.

lubasha [3.4K]

Answer:

X₁=7 ,X₂ = 5

Step-by-step explanation:

a= 1² b= - 12 c= 35

X =[ ( -b±√b²-4ac ) / 2a]

So, use this formula and get the answer...

Even if you use the middle term formula, you will get the same answer
