Answer:
6u(chicken) +3u(pork)+9u(lamb)+4u(fish)+8u(steak)= 30u
100%-30u
10%-3u
30%-9u
Answer is 30%
We want to find a solution such that
With these conditions, and .
Substituting the series into the ODE gives
so that the coefficients of satisfy
for , or
for . Notice that this implies a dependency of all beyond on , while takes on whatever initial value is given. In particular,
and so on up to
So we can extract two fundamental solutions such that , where
Recall that
which tells us
but is a constant solution and already accounts for the constant term in , and can be reduced to a simpler constant , leaving us with
The Wronskian is
so the two solutions are indeed independent as long as neither initial value is 0.
To solve this, multiply the fractions by each other.
7/8*4/5
7*4=28
8*5=40
28/40
"B" would be the correct answer but, it the fraction should be reduced to 7/10.
Hope this helps!
