hyperbola

 matematika lesson

hyperbola

ne cone if sliced horizontally, then the cut circle. If the cone is cut at an angle (and not cut the base), then formed an ellipse. If the slices cut its base and cut it vertically, then formed a hyperbole. If the slices are not cut off its base and cut it vertically, then formed a parabola.

We know it is the ellipse equation
\ frac {x ^ 2} {a ^ 2} + \ frac {y ^ 2} {b ^ 2} = 1

Hyperbola equation similar to equation ellipse. It's just that the sign is not positive, but negative. Hyperbolic equation is as follows:
\ frac {x ^ 2} {a ^ 2} - \ frac {y ^ 2} {b ^ 2} = 1

How graphic image of a hyperbole?
For instance the image graph of the equation: \ frac {x ^ 2} {16} + \ frac {y ^ 2} {9} = 1

Water is an essential compound for all known forms of life on Earth to date, [1] [2] [3] but not on another planet. [4] Water covers nearly 71% of the Earth's surface. There are 1.4 billion cubic kilometers (330 million miles ³) is available on Earth. [5] Air are mostly found in the sea (salt water) and in the layers of ice (in polar and mountain tops), but may also be present as clouds, rain, rivers, freshwater front, lake, water vapor, and sea ice. The water in these objects move follows a cycle of water: through evaporation, rain, and the water flow over the surface of the ground (runoff, including springs, rivers, estuaries) to the sea. Clean water is essential for human life.

In many places in the world there is a shortage of water supply. In addition to the Earth, a large amount of water is also estimated that there are at the north and south poles of Mars, as well as in the months of Europa and Enceladus. Water can be either solid (ice), liquid (water) and gas (water vapor). Water is the only substance which is naturally present on the surface of the Earth in its form the third. [6] Management of water resources is not good to cause water shortages, monopolisation and privatization and even spark conflicts. [7] Indonesia has laws governing water resources since 2004, namely Law No. 7 of 2004 on Water Resources

Water is a chemical substance with chemical formula H2O: one molecule of water is composed of two hydrogen atoms covalently bonded to one oxygen atom. Water is colorless, tasteless and odorless at standard conditions, ie at a pressure of 100 kPa (1 bar) and temperature of 273.15 K (0 ° C). This chemical is an important solvent, which has the ability to dissolve many other substances, such as salts, sugars, acids, some types of gas and many kinds of organic molecules.The state of liquid water is a situation which is not common in normal conditions, especially with respect to the relationship between the other hydrides are similar in oxygen column on the periodic table, which suggests that water should be a gas, like hydrogen sulfide. Having regard to the periodic table, it appears that the elements surrounding oxygen is nitrogen, fluorine, and phosphorus, sulfur and chlorine. All of these elements when bonded to hydrogen will produce gas at normal temperature and pressure. The reason why hydrogen bond with oxygen to form berkeadaan liquid phase, is because oxygen is more electronegative than the other elements (except fluorine).

Food Chain

IPA Lesson

Food Chain

In this article will discuss about the definition of the food chain. Keep in mind that a living organism in the world will always need other organisms and the environment. relationship between an individual and his environment is very complex, mutually influencing each other or reciprocal. Interrelationships between biological elements with non-biological form of ecological systems called ecosystems. Now it came to pass in the ecosystem food chain, energy flow and cycles of Biogeochemistry.
Understanding the food chain is the transfer of energy from the source in plants through a series of organisms that eat and are eaten.
Scientists recognize three kinds of ecological principal chain, ie the chain predators, parasites chain, and chain saprophyte.

understanding of the food chain

- Chain Predators
The primary basis of Chain Predators are green plants as producers. The chain starts from predators that are herbivorous animals as consumers I, followed by carnivores that prey on herbivores as consumers of the 2nd and ends on carnivorous and herbivorous predators as consumers-3.

PLANET

PLANET

planet taken from the Greek word meaning star Asteres Planetai Castaways. So named because it is different from a normal star, planet from time to time seen wandering (moving) from one constellation to another constellation.

Identification method can be done by naked eye with the experts in the field, or there is also the use of a special tool fingerprint reader (finger print reader) connected to a computer which then analyzes bersoftware special based on the points of reference.
