Find all the first order partial derivatives for the following function.f(x, y) = sin2 (8xy2 - y)
A. 
= 2sin (8xy2 - y) cos (8xy2 - y); 
= 2sin(8xy2 - y) cos(8xy2 - y)
B. 
= 16y2sin (8xy2 - y) cos (8xy2 - y); 
= 2sin (8xy2 - y) cos (8xy2 - y)
C. 
= 16y2sin (8xy2 - y) cos (8xy2 - y); 
= (32xy - 2) sin (8xy2 - y) cos (8xy2 - y)
D. 
= 2sin (8xy2 - y) cos (8xy2 - y); 
= (32x - 2) sin (8xy2 - y) cos (8xy2 - y)

Provide an appropriate response.To insure uniform viscosity and strength, the factory that makes hot sauce pumps two batches of the sauce into a single tank. They set the opening of the pipe from one batch so that it will fill the tank in 30 minutes. They set the opening of the pipe from the second batch so that it will fill the tank in 15 minutes. Write an equation and solve to find how long it will take to fill the tank when both pipes are used.
