Q:Find the additive and multiplication inverse of -2/3?

Inverses together make the identity for that operation. The identity for add is 0 so -2/3 and 2/3 are additive inverses because they add to be 0. The identity for multiply is 1 so -2/3 and -3/2 are multiplicative inverses because they multiply to be 1.

Q:I was wanting to know if trans fluid additives really help make the trans run smoother and better.if so what are some good brands I should be looking for.I have a automatic trans on a 1986 Ford F150

it will surely help provided there is nothing wrong with the inner workings, oil additives have always been questionable as a repair, both tranny and engine keep in mind that if the problem is a loss of frictional material, clutch or band the repair is obviously to replace the offending member, I have seen where an erratic shifting transmission has been temporarily helped by adding a transmission conditioner if a transmission is shifting erratically because of a sticking valve in the valve body and a check of the fluid shows dirty discolored fluid, the first check in any questionable performance question, if fluid doesn't pass the correct level,color,or smell test an internal repair is needed don't add a conditioner and procrastinate you are inviting major trouble! there's no such thing as a mechanic in a can!, consult you vehicle owners manual if available on checking fluid level,or an auto repair manual, available at most auto parts stores, in my mind oil conditioners in most cases are fine if used as a maintenance item, but cannot ad worn engine or transmission parts, remember that many uncommon noises emitted by your engine,differential or tranny are harbingers of needed mechanical repairs the severity being up to your interactionif that tranny is an AOD get it to a transmission shop

Q:Im looking for the oil additive they call free?

Oil additives are junk and can actually ruin your engine. If they were so great, then the racing teams would use them. I have a degree in chemistry, and can tell you that Slick 50 (teflon) and all the rest are a waste of money. Keep your oil changed on a regular basis (3000-5000 miles depending on your driving) and your motor will run smoothly for a long time.

Q:the question is, do they really work?i have seen them in various car shops,i have actually tried one ?18 i t was for 1 treatment it claimed reduce emmisions,stop smoke,more m.p.g. etc,etc,but i don,t think it made a blind bit of differenceis it just a rip off ????

Dragons breath and sand.

Q:a+b+chow do you do this???

I like crepe satin, I made a flower girls dress from it, and it is not as slippery. I think it is very elegant and a good choice.

Q:transmission slipping in a ford taurus is it a good idea to use stop slip transmission additive?

Just wondering. Did you end up using a automatic scooter or a full size motorcycle for the test? And did you get the M1 or M2 license? Thanks in advance.

Q:Need help for a Phyics quiz, thanks guys!

Suppose you have a group of resistors, either in series or parallel. Let the total current into the group be I and the voltage across the group be V. Then the power dissapated by the group is P IV If the group is a series connection then the current in each resistor is the same as the group current but the voltage across each resister is different and the total power can be written as; P I(V1 + V2 + .) IV1 + IV2 + . but this is just the sum of the individual powers If the group is a parallel connection the voltage is the same on each but the current is different and the power could be written as; P (i1 + i2 + .)V i1V + i2V + but this is just the sum of the individual powers So the additive property of power is due to the additive property of voltage in a series circuit and the additive property of current in a parallel circuit. Another way of looking at it is; if several elements in a circuit are using a certain amount of energy per second then the total energy used per second is the sum, regardless of how they're configured. Total energy used is total energy used.

Q:Do they make cigarettes with-out all the additives (nicotine etc.)?And if so what brands are they?

Nicotine isn't an additive. It is in the tobacco plant itself. The Latin name for the tobacco plant is Nicotiana. However, different species of Nicotiana have different levels of nicotine. Turkish tobaccos are relatively low in nicotine, next are Virginias, and Burley's have the most. I think that Kentucky is pretty high in nicotine too. Anyway, cigarettes are usually a blend of these kinds of tobaccos (Nicotiana). As far as additives, the most popular additive-free brand is Natural American Spirit.

Q:How can we prove that the additive inverse -u is unique of a vector space?

yes but at a very low temperature. some irons even have setting of what to set it at for each type of material.

Q:There was that big push years ago with those engine treatments like Slick 50, I‘m sure you remember them. Have those gone away? Currently I see some oil treatment additives that you add to the crankcase and it‘s supposed to condition the oil (somehow?) but it‘s already multi weight, so why would you condition the oil?

I would only buy a heavy oil treatment like Lucas if I hear a tapping, hoping that it will quiet it down or at least give it a little protection.
