Answer:
dy/dx = (cos y + y sin x) / (cos x + x sin y)
Step-by-step explanation:
y cos x = x cos y
y (-sin x) + dy/dx cos x = x (-sin y dy/dx) + cos y
-y sin x + dy/dx cos x = -x sin y dy/dx + cos y
dy/dx (cos x + x sin y) = cos y + y sin x
dy/dx = (cos y + y sin x) / (cos x + x sin y)
It’s 6 none of those r correct
Answer:
The length of the subway on the map is 
Step-by-step explanation:
we know that
The scale on the map is equal to the length of the subway on the map divided by the length of the subway in the actual
so
Let
z------> the scale on the map
x------> the length of the subway on the map
y------> the length of the subway in the actual

In this problem we have


substitute and solve for x
