Can someone check these answers for me? I got D and C respectively?
R(x)=0.0003x^2+.02x+1445 dR/dx = 0.0006x + 0.02 For small changes in x, Δx, the changes in R, ΔR, can be approximated by: ΔR/Δx ≈ dR/dx ΔR ≈ (dR/dx)Δx = 0.0006x + 0.02)Δx The change in x going from x = 420 to x = 421 is: Δx = 421-420 = 1 And the estimated change in revenue is ΔR ≈ (dR/dx)Δx = [0.0006(420) + 0.02](1) ΔR ≈ 0.0006(420) + 0.02 = 0.272 Rounded to the nearest penny, the estimated change in revenue between selling 420 dog houses and 421 dog houses would be $0.27 Ans: C y = 5x² - 2x + 3 dy/dx = 10x - 2 For x = 2, Δy/Δx ≈ dy/dx = 10(2) - 2 = 18 For small values of Δx, assume Δy/Δx is approximately equal to dy/dx Δy ≈ (dy/dx)Δx = 18Δx for Δx = -1/6 Δy ≈ 18(-1/6) = -3 Ans: B

Holy crap miss. If you don't answer it yourself no one will. :P
Can someone check these simple dimensional analysis questions for me?
Okay the first one I don't know how to do using the dimensional analysis so can some one help me in that one. Q)Convert 16.7 inches to feet Okay these I finished and I just need someone to tell me if they are ok or not. 1. 25 Yards to feet = 75 Feet 2. 90 Centuries to years = 9,000 Years 3. 84 miles to kilometers = 140 Kilometers 4. .00152 km to cm = 152 cm
!!Technetium-99m!! Help!!!!!?
Dude, this is Social Science, not Science. You'll get better answers in the Science - Chemistry department. However, you're lucky because I just finished my HSC Chem exam on Wednesday and am totally over the HSC! Anyways, I know all about it so I can help you :) Check these websites out, and if you want a more detailed answer from me, just EDIT your answer and I'll check it in 20-30 minutes time. Cheers :) http://www2.timesdispatch.com/lifestyles... http://dwb4.unl.edu/Chem/CHEM869Z/CHEM86... http://www.northland.cc.mn.us/biology/bi... I got full marks for my assessment by using these sites as well as random ones (e.g. Wiki) so just try reading them and see what you can do. EDIT if you want more help :) Good luck!

If someone has my account and routing number, how can they take money from my account?
I can think of three ways, and and there might be more but I should say I think all of them are very unlikely, All are serious fraud.Someone could use your account number on a ‘counter check’ and withdraw cash as you at a branch. In this case the teller would have to not properly verify identity.Someone would set up an ACH draft to transfer funds out of your account through ACH to a someone claiming you had authorized them to take those funds. The bank is supposed to be checking these sorts of things out to prevent this from happening, and there will be a very easy to follow trail to who got the money.Someone would counterfeit checks with your account number and RT printed at the bottom and then pay with the checks or cash them. Checks are hard enough for check printers to get right. The exact positioning of the numbers is important, the paper, watermarks, micro printing, and the ink is magnetic. These make this scenario unlikely, however, the person presenting the check could print whatever name on the check they wanted. Then because the name doesn't have to match the account to go through, they would use any valid-appearing ID matching the name printed on the checks.As mentioned, there may be more ways for this to happen, these are serious crimes, and I think they are all unlikely to be successful for a variety of reasons. The perpetrators are very likely to be caught. You would be well advised not to try any of them.
How can I find someone's cell phone number online?
For about 99% of cell numbers, you can't. I know this because our P.I. agency traces 50-100 cell numbers per month for our clients and we have to pay good money to get accurate results for them. Believe me (and we've been doing this for over a decade), if we could just go online and snatch up the answer for little or no money, we would NOT be paying serious dollars to get it through other, much more reliable means (more on that later). Feel free to try the freebie and cheapie sites that dot the Internet (but think twice about providing your credit card info), but you will nearly always end up with data that is either no longer correct or never was to begin with. Think about it, the FBI, CIA and NSA don't have access to a single, centralized, accurate, current database of all cellphone numbers and their corresponding owners. Do you really think that FindThatCellNumber.net does? And that, after spending millions of dollars to develop and maintain such an impossible database, they are going to share that info with you for $1.99? Not gonna happen. No such database exists and probably never will largely because of the tremendous competition in the U.S. cellular market. Ever notice that you can't watch TV for ten minutes these days without a commercial urging you to dump your current carrier for one of its competitors? Given that cutthroat rivalry, do you believe for a second that Verizon is going to voluntarily share the names and numbers of its subscribers (which, of course, changes daily and would have to be constantly updated) in any way that would allow Sprint, AT&T, etc., to poach its customers? Not a chance.Here's how we do it. We have confidential sources inside all the major cellular providers. When a client asks us to trace a name to a cell number (or the other way around), we call on these various sources to search their carrier's INDIVIDUAL databases, which are, of course, 100% accurate and up-to-date. The source who gets a "hit" for us gets paid for that info, which we, in turn, sell to our client. This is the ONLY way to get this done short of a court-approved subpoena, which is how the above-mentioned agencies and police departments find someone's cellphone number (yeah, I know it's much faster and cooler on CSI Miami but, SPOILER ALERT: TV's not real). Even then, they have to do it by presenting each of the various carriers with an individualized subpoena because, say it with me now, there is no centralized database!Home#FindCellNumbers
