D is the correct answer. The ordered pair of S' = (3.5,8.75).
Step-by-step explanation:
Given : A pentagon OPQRS is dilated by a scale factor of k=
from the origin, to create O'P'Q'R'S'.
We know that after dilation of any figure from the center by a scalar factor k,the coordinates of the new figure =(kx,ky), where (x,y) be the coordinates of the given figure.
From the given graph we can see the coordinates of S is (2,5)
Therefore, the coordinate of S'=(k2,k5)=![(\frac{7}{4}\cdot\ 2,\frac{7}{4}\cdot\ 5)=(\frac{7}{2},\frac{35}{4})=(3.5,8.75)](/tpl/images/0460/8478/04811.png)
Thus ,the ordered pair of S' = (3.5,8.75).
