Answer:
60 different possibilities 
Step-by-step explanation:
Number of bikers = 5
Positions = first, second and third
First positions = all 5 riders can take the first spot = 5 possibilities
Second spot = position 1 has been filled hence number of possibilities = ( 5 - 1) = 4
Third spot = position 1 and 2 has been filled ; number of possibilities =. (5 - 2). = 3
Number of possible arrangements :
5 * 4 * 3 = 60 different possibilities 
 
        
             
        
        
        
Answer:
 (c). 
Step-by-step explanation:
h(t) = - 16 t² + 80 t 
Coordinates of the vertex are: 
<em>t</em> = -  =
 =  = <em>2.5 sec. </em>
 = <em>2.5 sec. </em>
<em>h</em> = - 16(2.5)² + 80(2.5) = - 100 + 200 = <em>100 ft</em>.
