Given that w=x * e^-w use implicit differentiation to show that dw/dx=1/(e^w + x)

Given that w=x e -w use implicit differentiation to show that dw/dx = 1/(e w +x)Answer:Use product rule to simplify:dw/dx = x (de -w /dx) + e -w (dx/dx)Use chain rule to simplify even further:dw/dx = -x e -w...

The perimeter of a right angled triangle is 72cm. The length of its sides are in the ratio 3:4:5. Work out the area of the triangle.

Total perimeter - 72cm. Perimeter - (3+4+5)x -> 72=12x therefore x=6. The area of the triangle is 0.5(3x 4x) (because 5x is the longest side) therefore the answer is 0.5(18 24) = 216cm^2
