<span>There are lots of given in this certain item and we are
to note that other given are just there to distract us. In order to answer the
question, what we really need from the given is that there are 480 copies of
books and they arrived in 5 cartons. To determine the number of books in each
carton, we just have to divide 480 by 5 which gives us an answer of 96. </span>
Answer:
Third grade secondary = 87 students
Step-by-step explanation:
First grade = 30/100 x 250 = 75 students
Second grade = 35/100 x 250 = 87.5 rounded off to 88 students. Because students can't be half thus can't be in decimal. So round off to the nearest whole number.
Third grade = 250 - 88 - 75 = 87 students
Answer:
all work is pictured and shown
We can try reduction order and look for a solution 
. Then
Substituting these into the ODE gives
which leaves us with an ODE linear in 
:
This ODE is separable; divide both sides by the coefficient of 
and separate the variables to get
Integrate both sides; on the right, substitute 
so that 
.
Now solve for 
,
then for 
,
Solve for 
by integrating both sides.
Substitute again and solve for 
:
then for ,
So the second solution would be
already accounts for the second term of the solution above, so we end up with
as the second independent solution.
