Notice that , and .
Substitute these series into the ODE:
Shift the indices to get each series to include a term.
Remove the first term from both series starting at to get all the series starting on the same index :
The coefficients are given recursively by
Let's see if we can find a pattern to these coefficients.
and so on, suggesting that
which is also consistent with . However,
but we can adjust for this easily:
Now all the terms following resemble an exponential series:
Step-by-step explanation:
Step 1 is the same for both 1. and 2., so we will show it just once.
Step 1. Read the problem. Draw the figure and
label it with the given information.
.
1.
Step 2. Identify what you are looking for. the volume of the rectangular solid
Step 3. Name. Choose a variable to represent it. Let
V
= volume
Step 4. Translate.
Write the appropriate formula.
Substitute.
V
=
L
W
H
V
=

Step 5. Solve the equation.
V
=

,
142
Step 6. Check
We leave it to you to check your calculations.
Step 7. Answer the question. The surface area is
1,034
square
The answer is 2500 because just remove the 0's, what is half of 50? answer is 25 so yeah same thing but put the 0's back.
Hope this helps and if it does don't forget to mark as brainliest
