WILL GIVE BRAINLIEST IF CORRECT! Lydia graphed ΔDEF at the coordinates D (−2, −1), E (−2, 2), and F (0, 0). She thinks ΔDEF is a right triangle. Is Lydia's assertion correct? Yes; the slopes of segment EF and segment DF are opposite reciprocals.

Yes; the slopes of segment EF and segment DF are the same.

No; the slopes of segment EF and segment DF are not opposite reciprocals.

No; the slopes of segment EF. and segment DF are not the same.

step-by-step explanation:

no of data

divide by no of mode

⊂⊃⊂⊃ω

step-by-step explanation:

i hope this : )

the 4th choice is the correct one

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.
