An outfielder throws a ball to home plate. The ball’s path is modeled by the graph of y=x/5−x^2/1000, where x represents the horizontal distance of the ball from the outfielder, and y represents the ball’s vertical distance above the ground. What are the coordinates of the vertex of the ball’s path?

Which situation can be modeled by the inequality 5 + 10w ≥ 45? a. you start with $5 and save $10 a week until you have at least $45. b. you start with 5 baseball cards and purchase 10 cards every week until you have at most 45 cards. c. you start with 5 water bottles and purchases cases of 10 water bottles each until you have a total of 45 water bottles. d. you spend $5 plus $10 per week until you have less than $45.
