What should I use instead of the 4 weeks then? And I used 3.5 because of the prices that I sold for in the past, it gave the most revenue. And I don't know how to find the max of a function in general. Above poster said set the derivative to 0, but what would that look like?
I wasn't sure if I was just supposed to draw from the amounts that had previously been sold. I just took 3.50 from how much it had been sold for (from those listed prices) that gave maximum revenue. What am I supposed to use for the profit equation?

Oh duh! I always forget to just stick to one loop. I took off one of the 14.7s and got 100.4 as the correct answer. Thank you so much for sticking with me through that. I really appreciate it.
So 3.14 is the circuit current, and I used that to get the voltages at all the resistors. The only thing I don't know now is how to get the battery's voltage. I know that KVL states that all voltages should add to 0, so would that mean that I add up the voltages (47.1+38.622+14.7+14.7)? That...
Ok so I got 1.92 A for that, by taking 14.7 V divided by 7.66. That is the current for the middle branch if the calculations are correct. Now I combine those and that gives me the current for the first two resistors?
So I don't need the current for that at all then. I can just add up the voltages to 14.7 V and say that since they are in parallel, the voltage across that middle branch is 14.7 as well. Now, do I apply the 1.22 A of current to the 15 Ohm and 12.3 Ohm resistors and then add up all the voltages?
Alright so I'm starting at the 7.95 Ohm resistor and going forward, calculating the Voltage. I got 9.7 V for the 7.95 Ohm, and 5.01 V for the 4.11 Ohm. What do I do when I get to the 13.8 and 17.2 one in the middle. How do I know how the current splits up and how much enters those parallel...
1. Consider the group of resistors in the figure, where R1 = 12.3 and R2 = 7.95http://www.webassign.net/images/omegacap.gif. [Broken] The current flowing through the 7.95[PLAIN]http://www.webassign.net/images/omegacap.gif resistor is 1.22 A. What is the voltage of the batter...

I don't know why I can't get this problem right. I have 2pi√870/2227.2=3.92 then you would divide that by 2 because it's...
I just don't know what to put for Vhy or Vhx when putting it in to the conservation of energy equation to solve for the speed of the neutron. And how would I find the angle? which is the first part of the question
Sorry I just have 10 minutes to get this answer in so I'm trying to hurry. Will take me from an 85% to a 97% on the hw. I really appreciate all the help you've given me so far though
Really I'm unsure about what to do with the masses. Do I need to put in a value for them? Or just do 1 and 2 for them after multiplying by half for all of the figures in the energy
Alright here is the work that I've done so far. I have the two equations but I don't really know how to proceed because I have so many unknowns. Also I'm not sure where I should put sin41 and cos41. Obviously the sin would go in the Y equation and cos in the X but I'm not sure where exactly it...
1. A neutron collides elastically with a helium nucleus (at rest initially) whose mass is four times that of the neutron. The helium nucleus is observed to rebound at an angle '2 = 41° from the neutron's initial direction. The neutron's initial speed is 5.6 105 m/s.
