rate = k [A]^2 [B]^1 

Use the data from any trial to calculate k. 

k = (rate)/([A]^2 [B]^1) 

E.g., for Trial 1, we have 

rate = 3.0×10−3 M/s 
[A] = 0.50 M 
[B] = 0.010 M 

Plug those numbers in and crank out the answer. 

Now with the calculated value of k, calculate the initial rate for [A] = 0.50 M and [B] = 0.075 M 

rate = k [A]^2 * [B]^1 

k = calculated value 
[A] = 0.50 M 
[B] = 0.075 M
