Answer:
Step-by-step explanation:
This is permutation, since order matters.  The formula for us is
₁₈P₅ =  which simplifies to
 which simplifies to
₁₈P₅ = 
The factorial of 13 cancels out on the top and bottom leaving you with
₁₈P₅ = 18 × 17 × 16 × 15 × 14
which comes to 1,028,160 ways
Another way to look at it is:  the first 5 people of 18 finish and the others you don't care about.  Once the first place person is first, there are only 4 of the 18 left to finish in second place.  Then there are only 3 left to finish in third place, etc.  So if we use that reasoning, we don't even need to use the formula, we can just say
18 * 17 * 16 * 15 * 14 and those are the first 5 people of 18 to finish.
 
        
             
        
        
        
Answer:
C) 21
Step-by-step explanation:
a² + 20² = 29²       Use Pythagorean Theorem to solve for a
a² + 400 = 841       Solve for the exponents
      - 400 - 400      Subtract 400 from both sides
a² = 441                  Take the square root of both sides
a = 21
