All problems must be completed by the end of class to cam full credit. Show all work. 1. Quadratics. I once hit a baseball at Chase Fieldand managed to create an equation for the path the baseball took, which is modeled by .(x)=-0.0023x + 25x + 3.68 where x represents the horizontal distance from homeplate and dx) is the height of the baseball above the ground. (Both x and h(x) are measured in feet.) a. 4 points. Determine d(24). Round your answer to 2 decimal places. Then explain what your answer means in the context of the problem. ("In the context of the problem" means "in terms of the baseball's horizontal distance from the start and in terms of the height of the baseball above the ground.") 6.4 points. Determine the numerical value of the vertical intercept and explain what this means in the context of the problem c. 4 points. Determine the numerical values of the vertex coordinates and explain what they mean in the context of the problem d. 4 points. How far from the start did the baseball hit the ground? Round your answer to 2 decimal places. ち

Answer 1

d(x) = -0.0023 x ² + 0.25x + 3.68 d(x) Okx P a.) d (24) 3.68 -0.0023 * (24) ²+0.25 +(24) ² + 3. 8.35 (Approx) 6-) vertical intercept means x = 0 = 3.68 d (o) That it is hitted from height of 3.68 ft meana of point Q on the :-) If d(x)) is of the coordinate Curve that means after a distance the ball is at height d(x) from ground ground when d(x) = 0 hit the ball The 2 -0.00 23x + 0.25x + 368 = 0 = x = -0.25 & J (6.25)² + 4x0.0023 x 3.68 2x60.0023
