The coordinates of the vertices of triangle PQR are P(4, -2) , Q(6’ -4) , and R(8, 0). The coordinates of the vertices of triangle P’Q’R’ are P’(-4, 3) , Q’(-6, 5), and R’(-8, 1). Drag and drop the answer into the boxes to correctly complete the statement

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

i did it myself and i got 4.2 (b) hope its right

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.

so what is the problem what are they asking you to solve
