A massive and extremely remote celestial object, emitting exceptionally large amounts of energy, and typically having a starlike image in a telescope. It has been suggested that quasars contain massive black holes and may represent a stage in the evolution of some galaxies.
So basically, it is said that Quasars contain black holes within the center of it.
When it comes to identifying the location of black holes, there is compelling evidence that black holes are scattered throughout space, in galaxies as stellar remnants, and in galactic cores as supermassive black holes; and possibly primordial ones, remnants from the universe's origin; when using the term "sky" one might have to specify whether this is a metaphor (in the night sky might be interpreted as a view to outer space). Curiously enough, it's entirely possible that black holes are being created very briefly inside Earth's upper atmosphere in the form of microscopic ones caused by collisions of extremely high energy cosmic rays - originating at distant sources capable of accelerating particles and nuclei to relativistic speeds, some of which reach Earth. Fortunately these would be very short-lived and quickly 'evaporate' doing us no harm.
Yes.
All quasars are located at a great distance from us. Of the quasars discovered, they range from between 780 million and 28 billion light years away. Because of these distances and the velocity of light, we are seeing them early on in the creation of the Universe. They are very rare they have only found about 20 or so.

Sure; please note that black holes are among the brightest objects in the Universe. For more details, do some reading about quasars. Briefly, some quasars shine as bright as a hundred galaxies - and a quasar is a black hole.
It would emit a lot of radiation. Some distant black holes (or more accurately, the area around the black holes) emit more radiation than an entire galaxy. Such black holes are known as quasars.
Quasars are thought to be galactic black holes which are releasing focused energy from an accretion disk. The temperature could be as high as hundreds of millions of kelvins, but is detected due to its extremely high luminosity.
There are several formulae related to black holes. Please clarify what you want to calculate.There are several formulae related to black holes.

Quasars are related to supermassive black holes in the center of galaxies.
The things that we observe as quasars are believed to be caused by huge black holes.
Quasars are thought to be distant super-massive black holes.
Some scientist think that quasars may be caused by black holes, but they are not sure how this happens. Please dont copy. Use your own words! - Anonymous <3
No, a supermassive black hole is what makes a quasar.
Yes. Several quasars have been discovered; they are black holes, and they are quite active.
Bursts of light from black holes are the result of the accretion (or "consumption") of matter by black holes. Quasars are an example of this.

Astronomy answers questions about stars and galaxies and the universe, and black holes, quasars, super novas, and so forth.
That probably refers to a quasar. Quasars are related to gigantic black holes.
Probably the supermassive black holes that are believed to be at the centers of many (perhaps most) large galaxies. These may be related to quasars.
Each black hole and each quasar is the remnant of a single extinct star.
