A plane is flying at a bearing of N 64 degrees E for 447 miles, at which point, it adjusts its course so now it is heading N 67 degrees W. It travels NW for 762 miles. At the end of the journey, it is 583 miles from the point of departure. Find the bearing of the point of departure to the end of the journey. plss

your welcome. : )

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.
