Answer:
   48 ft
Step-by-step explanation:
For the quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For the given quadratic, which defines a parabola opening downward, the axis of symmetry defines the time at which the maximum height is reached.
   t = -48/(2(-16)) = 1.5
Then the maximum height is ...
   f(1.5) = (-16·1.5 +48)1.5 +12 = (24·1.5) +12
   f(1.5) = 48
The maximum height the object will reach is 48 feet.
 
        
             
        
        
        
 An easy way is to do it, if you get confused by multiplying fractions, is by turning the fractions into decimals. Since you are trying to find N you want to multiply the 1/5 by the 1/3.
1/5 = 0.2
1/3 = 0.33333333333333333333333333333333 
 if you multiply those you get 0.06666666666666666666666666666667 which when put into a fraction it equals 1/15 
but if you don't want to do that just try to remember that you want to get by itself. and when multiplying fractions in this situation the bottom numbers only matter.. so 5 x 3 = 15  1/15
would you like me to put it in a document to show you?
