Kyra is using rectangular tiles of two types for a floor design. a tile of each type is shown below: two rectangular tiles, rectangle pqrs with vertices at p(2, 2), q(4, 2), r(4, 8), and s(2, 8). rectangle jklm with vertices j(5 which statement is correct? (1 point) the two tiles are not similar because segment sp is to segment sr is 5 : 1 and segment mj is to segment ml is 2 : 3. the two tiles are similar because segment pq is to segment qr is 1 : 3 and segment jk is to segment kl is also 1 : 3. the two tiles are similar because segment sr is to segment sp is 3 : 2 and segment ml is to segment mj is also 3 : 2. the two tiles are not similar because segment pq is to segment qr is 1 : 6 and segment jk is to segment kl is 1 : 3.

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.

answer: a parabola

steps:

(x-1)(x+4)   = x(x+4) - 1(x+4) = (x^2 + 4x) - (x+4)

                = x^2 +4x -x -4   = x^2 +3x -4

which is a parabola
