We're looking for a solution of the form . By the chain rule, this solution should have total differential
and the equation is exact if the mixed second-order partial derivatives of are equal, i.e. .
The given ODE is exact, since
Then
With , we get
Answer:
50%
Step-by-step explanation:
Five out of 10 is 50%
The formula is
YC x YD = AY x YB
fill in what we know:
18 x 6 = 9 x YB
108 = 9 x YB
YB = 108 / 9
YB = 12
