WitrynaLatus rectum LL' passes through the focus (a, 0). Hence the point L is (a, y 1 ). There fore, y12 = 4a (a) y12 = 4a2 Take square root on both sides. y1 = ±√ (4a2) y1 = ±2a y1 = 2a or -2a The end points of latus rectum are (a, 2a) and (a,-2a). Therefore length of the latus rectum LL' = 4a. Equations of Parabolas in Standard Form with Vertex (0, 0)

WitrynaLatus Rectum = 4a Focus: (h, k+ (1/4a)) Directrix: y = k - 1/4a Graph of a Parabola Consider an equation y = 3x 2 - 6x + 5. For this parabola, a = 3 , b = -6 and c = 5. … In the conic section, the latus rectum is the chord through the focus, and parallel to the directrix. The word latus rectum is derived from the … Zobacz więcej Let the ends of the latus rectum of the parabola, y2=4ax be L and L’. The x-coordinates of L and L’ are equal to ‘a’ as S = (a, 0) Assume that L = (a, b). We know that L is a point of the parabola, we have b2 = 4a (a) = … Zobacz więcej Latus rectum of a hyperbola is defined analogously as in the case of parabola and ellipse. The ends of the latus rectum of a hyperbola … Zobacz więcej Witryna⇒ Area of triangle = 21×[−a(2a−0)−0+1(0−6a 2)] ⇒ Area of matrix = 21×(−2a 2−6a 2) ⇒ Area of triangle = 21×(−8a 2)= 4a 2(∵The area is a positive quantity, we always take the absolute value) Thus the area of the given triangle is 4a 2. Hene the correct answer is 4a 2. Was this answer helpful? 0 0 Similar questions does vw have electric cars
