Answer:a precise and unambiguous description of the meaning of a mathematical term. It characterizes the meaning of a word by giving all the properties and only those properties that must be true.
Theorem — a mathematical statement that is proved using rigorous mathematical reasoning. In a mathematical paper, the term theorem is often reserved for the most important results.
Lemma — a minor result whose sole purpose is to help in proving a theorem. It is a stepping stone on the path to proving a theorem. Very occasionally lemmas can take on a life of their own (Zorn’s lemma, Urysohn’s lemma, Burnside’s lemma, Sperner’s lemma).
Corollary — a result in which the (usually short) proof relies heavily on a given theorem (we often say that “this is a corollary of Theorem A”).
Proposition — a proved and often interesting result, but generally less important than a theorem.
Conjecture — a statement that is unproved, but is believed to be true (Collatz conjecture, Goldbach conjecture, twin prime conjecture).
Explanation:
Fuels such as coal,oil,and natural gas were formed over millions of years from organic matter like plankton, plants, and other life forms
Answer:
The relationship between the United States and oil can be described in many different ways, some of which are;
Explanation:
- The united states in the second largest producer of oil in the world, the use of energy is very high, as high as, one quarter of the energy in the world.
- Due to the high energy usage, the US is the largest importer of oil in the world.
- The United States is not comfortable with its dependency on oil and is in a struggle to end this.
