Q: A power house, P, is on one bank of a straight river 200 m wide, and a factory, F, is on the opposite bank 400 m down stream from P. The cable has to be taken across the river under water at a cost of $6/m. On land the cost is $3/m. What path should be chosen so that the cost is minimized?: Call the point across the river from the power house P' Call the point of intersection of the cable with the opposite bank C, which defines right triangle PP'C Let x be the distance from P' to C The two legs of triangle PP'C are 200 and x So the hypotenuse (the distance the cable travels underwater) is sqrt(200^2 + x^2) The distance the cable travels along the shore is (400 - x) (the distance from C to F) cost under water: 6sqrt(200^2 + x^2) cost on land: 3(400 - x) 1200 - 3x Total cost 6sqrt(200^2 + x^2) + 1200 - 3x Find derivative of cost: 6(2x) / (2sqrt(200^2 + x^2)) - 3 6x/sqrt(200^2 + x^2) - 3 Where derivative 0 will be a min for the cost 6x / sqrt(200^2 + x^2) 3 2x sqrt(200^2 + x^2) 4x^2 200^2 + x^2 3x^2 200^2 x^2 200^2 / 3 x +/- sqrt(200^2 / 3) +/- 200 / sqrt(3) but discard the negative root (since this won't be the minimum cost), so the distance from P' to the cable hitting land should be 200 / sqrt(3) 200 / (3^(1/2))

Q: I am setting up my mobile home with only 12 Volt devices. Could everyone look around their home and let me know what devices they have that are 12 Volt DC powered. As I shop for devices I will only shop from this list.For example, my cell phone is a LG -TMS20, with a LG fast charger model DC-45W which requires 12 Volt input at 0.3A 3.6W.If I use this in my mobile home, I can run it straight off the battery, and I don't need 110Volts AC.I will be making a list of every device you can find which runs off 12 Volts DC. I am looking for computer stuff, and sterio stuff.Thanks for your time: Not so many devices these days actually run directly on 12Vdc - usually they run on 5, 6, 7, 9, etc., Vdc. Rather than restrict yourself to only 12 Volt devices, how about investing in some good quality power Inverters that convert 12Vdc power sources to 110 VAC. Now all those gadgets that use 110 VAC input to convert down to 5, 6, 9, 12, 14, etc Vdc will work off of a single (or multiple) Inverters. Your wind generators, solar panels charge your 12V power bank and your 12Vdc to 110Vac Inverters power everything else in the house.

Q: i have PQI 12000 power bank that support 2A charge speed and a 550 mah wall charger can i charge the power bank on this charger ?or is it dangerous ?if it just time i don t care :Dand another question can i charge my phone (Galaxy Ace 3 1500 mah battery on 2A charger) ?: First, you should know that ONLY BATTERIES have mAh ratings. The h means hour. Chargers have only mA or A ratings. No h. Ever. Since 550 mA is only a little more than 25% of 2 A (2000 mA), there should be no problems. Phones have charge controllers in them, so that should work, too.

Q: I would like to know who deregulated airlines, banks, and electic power: Airlines were deregulated by the same folks who regulated them: the federal government. Airline Deregulation Act of 1978 Banks are regulated by both federal and state laws, which have been greatly loosened over the last 25 years. Electricity is regulated by both state and federal laws, which have been loosened over the last decade.

Q: I mean from my understanding when the privately owned banks (Federal Reserve) print money they also tack on interest rates and gain more power than even the Government. If the Government printed it's own money there wouldn't be interest rates. Now I understand printing money shouldn't be the answer because it causes inflation, but as long as their going to keep doing it at least make sense of it and have the Government do it.If the American people ever allowed the banks to control the issuance of their currency, the banks and corporations that will grow up around them will deprive the people of all property, until their children will wake up homeless on the continent their fathers once occoupied. Thomas Jefferson.: i think all government should control there economy and don't allow to few persons to control both economy and political interest of there country the free market theory has failed its better to the governments to but its hand on the sensitive issues on the economy like banks put a great taxes on the big foundations

Q: I am looking to get a power of attorney to make a purchase of a property for my mother. My mother is a foreign national, who travels to the US using a Visitors Visa. She currently has various US bank account. I would be making the purchase of a property using those account. How do i go about obtaining a power of attorney document in Virginia, USA. Where should the documents be file or does it just have to be notoried.?: The simplest way is to have her wire the money into your account, make the initial purchase in your name, and then you deed it straight over to her. However, that still leaves you open to Title problems, such as undisclosed liens, which the Seller might be hiding or might be unaware of, and Fraud, such as a Seller who doesn't own the property, or curable defects such as improper Probate in the record, then there are Environmental concerns, and the list goes on. Bottom line is that you need an attorney, and the attorney already knows what the Power of Attorney has to be, it's a commonly used form in such transactions, and there might be issues with a foreign-executed POA. As bigreg says, get an attorney, don't try this on your own.

Q: I need two examples of national, concurrent, and state powers please. Oh and please write them in simple terms :) Please and thank you!: B. Collecting Taxes.

Q: How does the mobile power charge?: The reason may have 1) your plug is not plugged in, 2) your mobile power built-in charging circuit has problems and can not work properly.

Q: What are the main factors in the mobile power time?: 1, the battery capacity (usually refers to the mobile power products on the nominal capacity): because the market mobile power capacity there are many, such as 2600mAh / 5000mAh / 5600mAh / 8000mAh / 10000mAh / 200mAhh and so on, of course, 2600mAh and 20000mAh

Q: I'm doing a mock trial, and I have to question Nicholas Biddle. I'm defending Andrew jackson that he did not violate the separation of powers wen he destroyed the bank. I have already questioned John Marshall and Andrew Jackson, asking questions along the lines of is the veto unconstitutional. Any ideas on what i can ask Biddle about the bank and if he thinks that Andrew Jackson should be innocent since all he did was veto? Questions can be about anything related to the bank: Ask him questions centering around the idea of whether it's right for one man to have so much power over other people's finances. Andy lost a lot of money because of the bank, so you could bring up that too. Do a lot about the common man power of the people
