Math help pls! Final is in 10 HOURS!!!
I'm reviewing my tests and these are some of the questions I got wrong from past chapters. If I could get help it will be greatly appreciated! My final is less than 12 hours away O.O! If anyone can help me with one (or more!!) of these questions it will be GREATLY GREATLY appreciated!! 1. Evaluate the limits and show appropiate work (not sure how to type it on here so ill write it out) The lim as x approaches 1 (x->1) in 1/(x-1)^2 I know that I have to make it so the denomiator isn't 0 when x=1 is plugged in, but not sure the steps I need to take to do that. 2.The lim as x approaches 0 (x->0) in {[1/(5+x) - 1/5]} / x (same as the previous, not sure how to get 0 out of the denom) 3. Find the value of the constant a in the following function that will result in it being continuous on the entire real number line:: s(x)= (x^2-a^2)/(x-a) , x does not equal a s(x)=-10 , x = a 4. A toy retailer has determined that they can sell 52,000 Transformer toys when the price is set to $7, and when the price is raised to 8.50$ the only sell 48,000 toys. Assume demand is linear, and that the variable and fixed costs for the store are $0.30 and $35,000, respectively. Find the marginal profit when 25,000 toys are sold. 5. Find dy/dx implicitly: e^(xy) + x^2 + y^2 = 10 6. Find the derivative g(x) = log (base 9) [(x^2)/(x-6)] 7. y=5^x

Good. Luck. With. That. :( I can't help you-- haven't learned that yet... taking grade 10 math! You just reminded me. I have a presentation to do on routers and switches tomorrow (didn't even know what that was). Better get started...

I miss math sooo much! I graduated 2 years ago, and only took some college so far....but I am going back and taking extra math, lol! Sorry, if I had my books it may come back to me, but been too long! I had a fantastic math teacher, though =) Good luck!

Too bad I didn't see this earlier. At a glace, they seem like reasonably simple single-variable calculus problems, and I'm sure I could've helped you out with that. I hope it all went well though. Now you just need to make sure to take a multivariable course while you're at it :D In my opinion that was a great course, but I might change my mind as I haven't seen the results of the exam yet (took it last week) LOL ___________ [color=gray]Chris, aka wushu_soldier[/color] [size=11][i]Sniper, maller, reseller Background shop of X-Mart Neomallers graphics designer[/i][/size]

I wish you were on! I needed a 74% on my final to average a B in the class; however, I skipped 3 questions and was unsure of 2 more (out of 14)! So I am under so much stress right now, checking blackboard every hour to see if my grade is posted. He said no curves or anything of that sort so blah. This is IT for math and me.. well besides statistics, but everyone said that is nothing compared to this lol. I take applied calc right now, it's a mandatory for my major gahhh .. hardest class i ever took! I spent more time on this class than all my other ones combined -_- and STILL is my lowest grade! I should have done that yahoo thing =( I procrastinated too long till i had 1/2 a day left.. it was too late lol
