Answer:
10.55%
Step-by-step explanation:
Given:
Initial weight of the new born baby = 3,874 grams
final weight of the baby = 3,465 grams
Now,
the current percentage of the weight loss will be calculated as:
Weight loss percentage = %
on substituting the respective values, we get
Weight loss percentage = %
or
Weight loss percentage = 10.55%
Answer: Hello mate!
Clairaut’s Theorem says that if you have a function f(x,y) that have defined and continuous second partial derivates in (ai, bj) ∈ A
for all the elements in A, the, for all the elements on A you get:
This says that is the same taking first a partial derivate with respect to x and then a partial derivate with respect to y, that taking first the partial derivate with respect to y and after that the one with respect to x.
Now our function is u(x,y) = tan (2x + 3y), and want to verify the theorem for this, so lets see the partial derivates of u. For the derivates you could use tables, for example, using that:
and now lets derivate this with respect to y.
using that
Now if we first derivate by y, we get:
and now we derivate by x:
the mixed partial derivates are equal :)
