A 160-lb man carries a 25-lb can of paint up helical staircase that encircles a silo witha radius of 20 ft. If the silo is 90 ft high and the man makes exactly three completerevolution. How much work is done by the man against gravity in climbing to the top?Suppose there is a hole in the can of paint and 9 lb of paint leak steadilyout of the can during the ascent. How much work is done?

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.
