The number of mosquitoes (M) that end up in a room is a function of how far the window is open (W, in cm2) according to M(W) = 5W + 2. The number of bites (B) depends on the number of mosquitoes according to B(M) = 0.5M. Find the derivative of B as a function of W.
The above functional compositions describe connections between measurements (as in Section 1.2, Exercises 53-56). Find the derivative of the composition using the chain rule.
