xinname 1 Posted February 2, 2011 Okay, so this isn't really homework, but I need your guy's opinions. I work for the school newspaper, yada yada, and I sometimes mess up on my articles. So, I need you guys to tell me what I did wrong. Tell me if you think I need to add something, if I made a typo, if I made grammar mistake, if you have questions, comments, etc. What my teacher wants me to have on the article is the 5 W's (Who, what, where, when, why), two quotes, insight, information, a picture (which I can't show on here)... and maybe some other stuff that I forgot about. The article is about school absences btw. Absences According to Debbie Aldama, an average of around 290 students are absent everyday out of all 1545 students.

Think Pink 1,967 Posted February 2, 2011 Science question~ What are the four factors that affect the rate of a chemical reaction? My class had a huge scandal and, there only being eleven of us in the entire grade, some of us missed some things. And now it's on homework ;; So, I know two: catalysts and temperature. Anyone know the other two? Quote Share this post Link to post Share on other sites
bambii 34 Posted February 2, 2011 Science question~ What are the four factors that affect the rate of a chemical reaction? My class had a huge scandal and, there only being eleven of us in the entire grade, some of us missed some things. And now it's on homework ;; So, I know two: catalysts and temperature. Anyone know the other two? Hm... I'm gonna take a guess here. One obvious factor is the concentration, or amount, of the reactant. If you increase the concentration of the reactant you are using (the thing that's being added to induce the chemical reaction), you'll increase the rate at which the reactions happen. Also, the conditions in which the reaction is occurring could definitely have an effect on its rate... you could be surrounded by liquids or gases, you could be in a very polar region or a very nonpolar region... all these things could potentially affect the rate of a reaction.

Thanks. Definately the concentration, but I don't think the second one was one. [/color] Quote Share this post Link to post Share on other sites

Anti-SOLDIER 68 Posted February 18, 2011 ^ I never tried that before. Thanks for telling me. I made a new article and it's about homework. Tell me if you see anything wrong with it.

lizzie1238 538 Posted December 3, 2011 Yeah. Except there's not a bunch of itty-bitty spaces inbetween like mine. Ok, so you have 9>x+23 and a straight horizontal line. What are you supposed to do with them? Quote Share this post Link to post Share on other sites

Think Pink 1,967 Posted December 3, 2011 Sorry, but I don't think I can help you. How are you supposed to graph something with no y-value? Not sure, but apparently it's doable. I had an example problem, but it's really not helping much. It was like 6<9-x -9 -9 -3<x <---------o <-------------------> -4 -3 -2 The bold part is a part my teacher drew on the paper.

Its been a while since I've done algebra but I'm pretty sure this is a linear ineaquality essentially your solving for x .9>x+23 now first like solving for any equation you need to isolate the variable you do this by subtractin 23 on both side you need to isolate the variable which is x 9>x+23 -23 -23 -14>x now its solved because you don't know what the x varible is but you know that it is less then -14 -14o-----------------> any number that is higher then negative 14 is the answer so it is explained on the graph this way.

Cricket 1,180 Posted December 5, 2011 for those who are doing inequality graphing, lesser than or greater than is always an open circle when graphing. greater than or equal to and lesser than or equal to is always going to be a closed circle when graphing. 2 Koko and Sora96 reacted to this Quote Share this post Link to post Share on other sites
lizzie1238 538 Posted December 5, 2011 A parabola passes through the points (3,0), (7,0) and (9,-24). I need to determine the vertex of the parabola and write the equation in vertex form (y=a(x-h)^2+k). I've already figured out that the equation of axis of symmetry (or x coordinate of the vertex) is x=5. I would substitute that into the equation to find the y coordinate, but that will not work because I do not have the a value in the equation. Can someone help me?

Key2Oblivion 37 Posted December 22, 2011 Well this isn't really a question for homework, but does anyone have any tips on college level chem? Like I started off the year pretty poorly, mostly because I wasn't trying. But my coach got on my case saying that I needed a 2.0 GPA and I needed to bring my grades up. So my B's became A's and my D in Bio became a C+(possibly B- depending on how I did on the final). So everything has gotten much better, except for chemistry. I WAS averaging a C-(71 to be exact) but the final yesterday kicked my ass, so I'm looking at a D right now(I think). So my GPA should be over a 2.0 but I really need help in chemistry. Anyway, next semester is Chem 104, General Chemistry II. So If you feel like you can help me send me a message and hopefully I can do something for you in return.
