Notice that the reflection is over a line of the form x=constant; in this case, the y-coordinate of the reflected point stays the same while the x-coordinate changes as expressed by the transformation below
Hence, in our case
Transform points N, M, and O accordingly,
ANSWER
10.0 ------- Vivian is correct
EXPLANATION
Firstly, find the cube root of 1010
In the above calculation, the cube root of 1010 is 10.003
The correct approximation of the above value is 10.0. This is because the hundredth value is not upto 5
Recall, figures from 1 - 4 are rounded to zero and figures from 5- 9 are rounded up to 1
since 3 is not upto 5, so it is rounded down to zero
Therefore, Vivian is correct
