WebNov 14, 2015 · To find the locus of the foot of perpendicular to this chord from the centre of the ellipse, I wrote the equation of chord with parameters $ A , B$: $$\frac xa\space\cos{A+B\over 2} + \frac yb\space\sin{A+B\over 2} = \cos{A-B\over 2}$$ Since an angle of $90^{\circ}$ is subtended at the centre, I get the condition that $\tan A\tan B = … WebA free-throw line 2 inches wide should be drawn across the circles, parallel to the end, and 15 feet from the face of the backboard. The three-point field goal area should have parallel lines 3 feet from the side and an arc of 23 feet and 9 inches. Four hash marks 2 inches wide should be drawn perpendicular to each side and 28 feet from the base.

Perpendicular Foot -- from Wolfram MathWorld

WebSolution The correct option is A 3 x – 4 y = 25 Explanation for the correct option: Let P 3, - 4 be the foot of the perpendicular We know that slope of line joining two points x 1, y 1 and x 2, y 2 is y 2 - y 1 x 2 - x 1 ∴ Slope of line O P is m 1 = - 4 - 0 3 - 0 = - 4 3 Let slope of line passing through P be m 2 WebMar 13, 2024 · Equation of line passing through P and is perpendicular to line.
