What is the final elevation if a. A bird starts at 20 m and changes 16m? b. A butterfly starts at 20 m and changes -16m? c. A diver starts at 5 m and changes -16m? d. A whale starts at -9 m and changes 11 m? e. A fish starts at -9 meters and changes -11 meters?
Since the bird's initial elevation is 20 m and it changed 16 m in positive direction, so bird's final elevation will be: Therefore, bird's final elevation will be 36 m.
