write a quadratic function, h(t), that shows the height, in feet, of the soccer ball, t seconds after it was kicked. Use the general equation h(t) = -16t2 + v_ot + h_o where v_o is the initial velocity and h_o is the initial height. Show how you got the x-intercepts, the vertex's as well as graph it. How long was the soccer ball in the air?

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
