Sia ? 6 years, 6 months ago

Parallax is a method of measuring distance to an object. Similar to how our binocular vision helps us determine distance, the direction to a distant point is slightly different from two separate observation positions.

The method where the position and direction of the object changes when we observe from some different position is called a parallex method .

Let (N) is the near by star whose distance D from the earth is to be found F is far of star whose direction and position of earth in the orbital motion. When the earth is at A the parallax angle is (thita1) after six months the earth is at opposite position B the parallax angle become (thita2) (Thita)=(thita1)+(thita2) (Thita)=Parallex angle.

ANSWER

The line thorough the point (h,3) and (4,1) interest the line 7x-9y-19=$ at right angles find value of h

Posted by Priyan Tiwari 6 years, 6 months ago

CBSE > Class 11 > Mathematics

1 answers

Sia ? 6 years, 6 months ago

Slope of the line passing through the points (h, 3) and (4, 1) is
{tex}= \frac{{1 - 3}}{{4 - h}} = \frac{{ - 2}}{{4 - h}}{/tex}
Also slope of the line 7x - 9y - 19 = 0 is {tex}\frac{7}{9}{/tex}
Since two lines are perpendicular to each other
{tex}\therefore \frac{{ - 2}}{{4 - h}} \times \frac{7}{9} = - 1 \Rightarrow \frac{{ - 14}}{{36 - 9h}} = - 1{/tex} {tex}\Rightarrow{/tex} -14 = -36 + 9h
{tex}\Rightarrow{/tex} 9h = 36 - 14 {tex}\Rightarrow h = \frac{{22}}{9}{/tex}
