We have five slots to fill: Slot A, Slot B, Slot C, Slot D, Slot E

There are 9 choices for slot A
There are 8 choices for slot B (we can't pick the same object twice)
There are 7 choices for slot C
There are 6 choices for slot D
There are 5 choices for slot E

Multiplying these values out gives us 9*8*7*6*5 = 15120

Final Answer: 15120
