Ex 11.2, 5 Find the coordinates of the focus, axis of the parabola, the equation of directrix and the length of the latus rectum for y2 = 10x Given equation is y2 = 10x. Since the above equation is involves y2 Its axis is x-axis Also coefficient of x is positive (+) Hence we use equation y2 = 4ax Latus Rectum is 4a = 4 × ﷐5﷮2﷯ = 10
