The high point in the trajectory of the ball occurs at a distance of 18 m from the kicker On the downward path, another player heads the ball at a height of 2.2 m from the ground G ball is kicked. It will help to draw a sketch of the situation. Put the origin (0, 0) at the point where the Question 4 (1 point) 9 What are the coordinates of the vertex for this situation? Question 5 (4 points) Write a quadratic function that models the situation Paragraph B E. Lato (Rocom... Question 6 (2 points) How far from the kicker in the line of the trajectory must a player be to head the ball as described? (On the downward path, another player hands the ball at a haight of 2:2 m from the ground.) Hint: You can colve algebraically or use your oatoulator. Paragraph Lato (Rocom... ~ Question 7 (1 point) Describe at least one assumption you are making in using this model to determine the position of the player heading the ball Paragraph BY Lato (Rocom.. 10px A retail electronics chain makes a profit of $14 on every MP3 player of a certain brand the chain sells. Last month the chain sold a total of 600 of these MP 3 players nationwide. The marketing department suspects that for every $1 decrease in price, the chain would sell an additional 100 players The marketing department is interested in maximizing the gross profit on this item. gross profit = (profit on each MP 3 player)(number of players sold) Let y equal the gross profit, and let x equal the number of dollars the MP 3 players are discounted. The profit per MP 3 player will then be (14 - x). Question B (2 points) Write a function to model this situation. Paragraph B - E Lata (Racom. 10px C ASUS
