Triangle abc is located at a(0,4) b(2,3) and c(-1,-2).after being rotated 90° clockwise around the origin, what are the new coordinates of point c?

C= (-2,1)

Step-by-step explanation:

When you rotate a triangle, or shape, 90 degrees clockwise, the rule is (x,y) then turns into (y,-x)

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.
