Can you give the things you have to match?
Answer:
D. No, because the differential equation does not have constant coefficients.
Step-by-step explanation:
The undetermined coefficient method cannot be applied to non homogeneous variables. The differential equation does not have constant variables therefore the method of undetermined superposition can not be applied. To complete a solution of non homogeneous equation the particular solution must be added to the homogeneous equation.
To find avg downstream is 39/3 = 13 mph
upstream is 20/4 = 5mph
the average of the 2 is the still water speed which is 8 mph
I think it’s the last one
