Very quick question!! Will fan and medal!

OpenStudy (help!!!!):

If w is inversely proportional to the square of v, and if w=1 when v=6, find w when v=3

OpenStudy (help!!!!):

I got w=2 but my answer key says w=4. Help!!

OpenStudy (caozeyuan):

w=k/v^2, where k is a number to be determined

OpenStudy (caozeyuan):

so 1=k/36, k=36

OpenStudy (caozeyuan):

now v=3 so w=36/9=4
