Which of the Following H and K Values Will Produce

Question

Which of the following h and k values will produce a triangulation number of 13?
A) 1 and 1
B) 1 and 2
C) 1 and 3
D) 2 and 3
E) 2 and 4

Accepted Answer

The triangulation number (T) for a virus is calculated using the formula T = h^2 + hk + k^2, where h and k are integers that define the positions of the capsomeres. For T = 13, using the values h = 1 and k = 3, we get T = 1^2 + 1*3 + 3^2 = 1 + 3 + 9 = 13.
