I've roped all my friends into helping me with this...! Yet my teacher has looked over them and declared all their attempts as incorrect! He hints that : 1/2(n squared - 3n+2)c
(but doesn't this actually make the formula more complicated?) could anybody please help me?

(I know, I know primary level stuff... but the definitions have to be spanking!) I feel somewhat unprofessional citing wikipedia as a reference for certain things too..
Hey everyone. I have a really simple question. I'm in the process of writing a discussion paper for my biology lab, but I'm completely stuck. The assignment is as follows:
Prepare a table comparing all of these organisms [Hydra, Planaria, Ascarus, Lumbricus, Crapidula, Lancelet, and Seastars], and write out your discussion and conclusions about the relationships between body form and life style in invertebrates.
I have the table completed. What I thought we were supposed to be looking at is the type of symmetry each organism has, and how that relates to what kind of environment it lives in, how it eats, moves, and reproduces. However, I'm not sure how I can really compare these organisms to that degree based on only the type of symmetry.
I'm not here looking for answers. I have most everything in the lab manuel and in my notes. I'm just having trouble relating that information to the life styles.
hey, I'm doing my Australian HSC physics by distance education. unable to get hold of my teacher for daaaays. if any one can tell me what I'm doing wrong here that would be great.
Q. A cyclist undergoes three successive displacements. First is 120m at 40 degrees North East. Second is 82m at 72degrees South East and third is 195m at 35 degrees South West.
As I understand it is done in components. Finding the x component and y component of each displacement and then adding all the x components together. then adding the y components together. then squaring both values, add together and the find the square root. then find the angle. these are the components I get.
Force x component y component 120m 120cos40 = 91.9 120sin40 = 77.1 82m 82cos72 = 25.3 -82sin73 = -78.4 195m -195sin55 = -159.7 -195cos55 = -111.8
r= -42.5 -113
r= square root of (42.5^2 + 113^2) = 120 angle is tan(-1)(113/42.5) = 69 degrees so my answer is 120m at 69 degrees.
Thats what I get. The answer in the book is 102.7m at 24.9degrees South East. ??
I hate to have to be OTT, but i'm desperately looking for a copy of some mayfield data handling maths coursework. The deadline is tomorrow, and i've been in hospital until today, the teacher won't change it as it's a school deadline. I'd struggle doing this anyway and theres no way to do it in one night. So if you've done it and still have it or know someone who does, PLEASE OH PLEASE send me yours just as a guideline! My email is anarcheese@web.de PLEASE!! Thanks in advance Eva
Hey guys! In Physics we're doing an experiment to see how the resistance changes with length, but I'm having extreme difficulty in the experiment: even the preliminary work! For example, how many lengths do I need? How can I keep the current and voltage the same for each length? Everything like that. I've been off recently due to an illness and my teacher is refusing to explain it to me! Finally, I know that as the length increases so does the resistance, but I've no idea of the "scientific knowledge" behind it!
I have been taking chemistry for a while now, and recentley have been getting confused. And the more I get taught the more I get behind because Im not understanding it. I took old problems that I got wrong on past quizzes, tests, and homework and tried to work them to get the right answers. But, am having trouble. There are 80 questions that I compiled together to try to understand. If anyone could do them for me so I at least know the answers, it would be great. Let me know! ASAP, PLEASE! thanks!
