3) Solve: Ned wants to look at the top of a tree. There is a
mirror on the ground that reflects the image so
that MEN * ZTER. The tree is 16 feet tall
while Ned is 1 foot tall. If the mirror is 1 foot
from the tree, how far should Ned stand from
the mirror?
A. 1/16
B. 17
C. 16
D4

what does x eaqual

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.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
