Planes A and B intersect. Vertical plane B intersects horizontal plane A. Point W is on the line where the planes intersect. Vertical line m is on the left half of plane A. Horizontal line n intersects line m at point X and line k at point W. Line l is on the lower half of plane B with point Y. Which describes the intersection of plane A and line m?

i dont know

step-by-step explanation:

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.

here is a big fat
