WebSketch the graph and determine the coordinates for the focus and the equation of the directrix for the parabola given by the equation y^2 = -8/3 x. View Answer. For the parabola given by (y - 3)^2 = 8 (x + 2), find the focus. View Answer. Write the intercept form equation of the parabola. f (x) = -1/4 x^2 + 5/4 x. Webof the parabola is 3.0 meters and the depth of the form is 1/2 meters. How far above the center of the form will the sunlight be the most concentrated? Answer: The diameter is 3.0 meters so the radius is 1.5 meters. The point (1.5, 0.50) is on the parabolic curve, so 0.50 = a (1.5) 2 and so a = 0.22. Then the focus is at f = 1/(4x0.22) = 1.1 paignton holidays 2020

As you noted, positive H is to the right, negative H (which shows up as y = (x+h)^2 - k where the value of h is actually positive) is to the left. Positive k is up, negative k is down. 1 comment ( 2 votes) Marcos/Freddy fazebear 2 years ago styling thermals
