Notice that the function xy is harmonic in the half-plane {y > 0} and vanishes on the boundary line {y = 0}. The function 0 has the same properties. Does this mean that the solution is not unique? Explain.

step-by-step explanation:

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.

just sum

10 + 10 = 20
