You need to take your mom’s old broken washing machine to the dump. You have a dolly on which to move the 200-pound washer, but you want to build a ramp to roll it off of the front porch of your house. You have an 8-foot board with which to make a ramp from your front porch. If the porch is 2 feet high, what is the horizontal distance from the porch that the ramp would reach? Safety guidelines state that the angle of elevation for ramps should be at most 5 degrees. Does your ramp meet safety guidelines? Sketch a picture and solve showing all your work. Round answers to the nearest tenth.

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.

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
