answer the question

2. A parabolic satellite dish is pointing straight up. Along a cross-section that passes through the centre of the dish, the height above ground is given by the following equation: y = 100 (x2 - 100x) + 40 2a Find dy dx V x 2 100 - x + 40 dy dx dx . . dy 2x dx = 100 (1) +0 . . . V dy = x dx 50 - 1 .. . 2b For what value of x is equal to 0? Enter your next step here () dy ab dx
