Homework Statement I won't go into detail as I am just trying to figure out the methodology of this problem. Having said that: I have 3 inputs. These 3 inputs are connected to a hidden layer of 3 other nodes and then a single output node. Each node of ABC is connected to each node of DEF and...

By pure plutonium I just meant to ask if uranium was used for both the fission and fusion reactions. Do you have any sources on plutonium no longer being made? I'm trying to find anything saying this but can't. Googling "dismantle plutonium reactor", "plutonium no longer made", etc doesn't get...

My only interest in the plutonium production is the amount and type of waste that we created while it was in production. Also, are not some fusion weapons still using Pu-239? Or are these weapons being phased out for pure plutonium?

I see my mistake. I was confusing the production of Pu-239 with U-235. So, the only step to making weapons grade uranium is the conversion to uranium hexafluoride and then enriching 235. Thank you for clearing that up for me. I knew that 235 occurred naturally but was thinking putting 238 into a...

I understood that. Can you point out where you see me misrepresenting that? I just want to make sure I have my vocabulary correct since you see a mistake. I know that U-238 goes in the reactor and, after being bombarded by neutrons, begins producing a variety of isotopes including U-235. Once a...

Homework Statement (This isn't a typical problem here so feel free to suggest an alternative forum category or website.) I'm trying to do research for a paper about nuclear waste and depleted uranium storage by the DOD. I have a lot of questions I need to answer before I can get too far into...

Okay, I just noticed my mistake as well. Thats what happens I write on my phone as I'm falling asleep in bed. Thanks for the help

But, that would make 68 nodes in level 4.

173-85=88, so 22 nodes in level 4 have children and 44 are leaves. 44+88=132. That's too many, I think. Have I made a mistake?

Yes sorry, i fixed it. I pasted plain text and took them out for some reason.

Homework Statement Let the function t(n) be defined recursively by: ##t(1) = 1## ##t(n) = 3t(\frac{n}{2}) + n + 1## for n a power of two greater than 1. Draw several levels of the recursion tree for t, and answer the following: What will the height of the tree be if n is a power of 2...

I started the problem this way but couldn't figure out how I could simply get the number of leaves. I mean, some of the 4th level clearly have leaves but I have no idea how many. That is why I resorted to examples.

Homework Statement (I'm struggling with trees now so I expect to have a lot more questions on here like this) I have a 4-ary tree with 173 nodes. How many leaves do I have? Homework Equations The Attempt at a Solution So I know that each node, if it is not a leaf, will have 4...

Yeah, sorry I keep not counting ##n^2##. So, I need to to go from 0 to k-1. Since, k is 1 more than the total number I need to sum. The TA gave an answer that didn't make any sense to me. They got the summation of ##f(n) = k+f(n-k)+\sum_{i=0}^k i^2## but I don't see how that is correct at all.

3 1's and 2 (n-1)'s. then k 1's and k(n-i)'s. So it should be summed from 0 to k-1, then.
