BASEBALL For Exercises 19–21, use the following information.
Three players are warming up for a baseball game. Player B
stands 9 feet to the right and 18 feet in front of Player A.
Player C stands 8 feet to the left and 13 feet in front of Player A.
19. Draw a model of the situation on the coordinate grid.
Assume that Player A is located at (0, 0).
20. To the nearest tenth, what is the distance between Players A
and B and between Players A and C?
21. What is the distance between Players B and C?

22. MAPS Maria and Jackson live in adjacent neighborhoods. If they superimpose a
coordinate grid on the map of their neighborhoods, Maria lives at (9, 1) and Jackson
lives at (5, 4). If each unit on the grid is equal to approximately 0.132 mile, how far
apart do Maria and Jackson live?
