The energy of bird flight as a function of body weight is given by, E = 429 w−0.35, where w is the weight of the bird (in g) and E is the brain weight (in cal/g/hr). Suppose that the weight of a bird weighing 10 g is increasing at a rate of 0.001 g/hr. Find the rate at which the energy expenditure is changing with respect to time in cal/g/hr/hr to four decimal places.

Step-by-step explanation:

Energy of bird flight is given by

Differentiating with respect to time we get

Now when

The rate at which the energy expenditure is changing with respect to time  is

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8
