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= $\frac{7}{4}$ 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)= $(\frac{7}{4}\cdot\ 2,\frac{7}{4}\cdot\ 5)=(\frac{7}{2},\frac{35}{4})=(3.5,8.75)$

Thus ,the ordered pair of S' = (3.5,8.75).

Alaska is -3 degrees, lowa is 5 degrees, Idaho is - 7 degrees, New York is 9 degrees,
