Q:is 1 an additive identity and please explain

The identity element of a group has the property that if you combine it with any other element, x, of the group using the group operator, you get x. The additive identity of a field is the same thing, except that it applies to the field's addition operator. It is the value I* such that x + I x. *I'm somewhat abusing the notation here. I is the customary symbol for the identity matrix. The additive identity for a field usually is named 0, hopefully for obvious reasons.

Q:Is there a fuel additive that really improves MPG a lot other than those the remove carbon?

I recently read an artical in USA today that stated after testing many supplements, there is a minimal boost in mpg when using any fuel additive. The most was a bare 1% improvement in mpg. Being in the automotive business for over 20 years, I can tell you that your best bet to reduce your fuel intake is modifying your driving habits. Take off slower from stops, don't jack-rabbit away. Keep to the speed limit. Don't be a lead foot. And keep up with maintaining your vehicle. Regular tune ups, oil changes, etc, will go a long way towards saving money on fuel.

Q:-5/10, 13/6, -4/1Please Explain how to give these fractions a multiplicative and additive inverse! Help!

multiplicative inverse is the same as reciprocal. It is what you multiply the fraction by to get 1. -5/10 ---- -10/5 13/6 ---- 6/13 -4/1 ---- -1/4 additive inverse is what you add to get 0, so basically it is just the opposite sign: -5/10 ---- +5/10 13/6 ---- -13/6 -4/1 ---- +4/1 that's it! ;)

15% to 20% improve is practically impossible. any fuel additive that claims that kind of performance, it's a scam. although you can still use the additive to help clean up your fuel system, but that's very minor too. Don;t waste your money on fuel additive and make your to keep your car tuned.

Q:Im doing a case study on additives and although i know that hyperactivity most probably is caused by certain additives, i cannot seem to find any scientific explanation as to why.

Additives for chemicals have different purposes. If you are studying effects of medicines, there are many class of additives. Most common are fillers - This compounds help in preparing dilution for tablating (or other forms of medicines) to help tableting exact dose. These are generally starch or salts. There are some additives being used to encapsulate the medicine. This help in delivering the medicine in the targeted zone. his compounds protect the medicine from being absorbed in region where it is not required - and in most cases it works on pH balance or presence of some specific ions. This compounds indirectly help in improving the efficiency of medicine. Some additives are made to increase the efficiency of the medicine. They are some times other medicine - combination preparations or some enzyme like compounds. It is known as synergistic effect. Increased efficiency - effect of medicines can be identified as hyper activity in body. Some additives are binders - that help tablating.
