Explanation:

Compounds are those substances that are made up of elements that are combined in a fixed proportion or ratio. The individual property of element is lost once it forms a compound. The physical and chemical properties of both compound and an element is different.

Example of a compound is water and its elements are hydrogen and oxygen. Water is a colorless liquid that acts as a solvent and dissolves most of the solutes in it. While oxygen and hydrogen occurs as gases in their elemental state.

Answer:

Compound: It is pure substance.Compounds are formed by two or more atoms of same of different element  and elements are combined in fixed proportions or ratio.

Explanation:

Compound: It is pure substance.Compounds are formed by two or more atoms of same of different element  and elements are combined in fixed proportions or ratio.

The physical properties and chemical properties of compound are different from the physical properties and chemical properties of constituent elements of the compound.

For example

Water is a compound

It is consist of 2 atom of hydrogen and one atom of oxygen.

Hydrogen and oxygen are both gases in their  elementary form , but water is a colourless liquid and act as a  solvent.Most of the solutes dissolve in it.

Define:

solar system : The Solar System is the gravitationally bound planetary system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, such as the five dwarf planets and small Solar System bodie

big bang theory : The Big Bang Theory is the leading explanation about how the universe began. At its simplest, it says the universe as we know it started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today

nebular theory : the theory that the solar and stellar systems were developed from a primeval nebula

heavy elements : the Universe starts off with hydrogen and helium, all stars produce helium, and then stars over a certain mass threshold produce carbon, nitrogen, oxygen and lots of heavier elements

composition : solar composition, compared to earlier measurements, are enriched in Fe and Ca relative to Mg, Al, and Si. The Fe/Si and Ca/Al atomic ratios are 30 to 40 percent higher than chondritic values. These changes necessitate a revision in the cosmic abundances and in the composition of the nebula from which the planets accreted (which have been based on chondritic values).

milky way galaxy : The Milky Way is the galaxy that contains the Solar System. The name describes the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye

scale: In astronomy, magnitude is a unitless measure of the brightness of an object in a defined passband, often in the visible or infrared spectrum, but sometimes across all wavelengths. An imprecise but systematic determination of the magnitude of objects was introduced in ancient times by Hipparchus

biosphere : the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.

atmosphere : the envelope of gases surrounding the earth or another planet.

"part of the sun's energy is absorbed by the earth's atmosphere"

synonyms: air, aerosphere, airspace, sky;

geosphere : any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere.

redshift :the displacement of spectral lines toward longer wavelengths (the red end of the spectrum) in radiation from distant galaxies and celestial objects. This is interpreted as a Doppler shift that is proportional to the velocity of recession and thus to distance.

cosmic background radiation: The cosmic microwave background (CMB, CMBR), in Big Bang cosmology, is electromagnetic radiation as a remnant from an early stage of the universe, also known as "relic radiation". The CMB is faint cosmic background radiation filling all space. ... This glow is strongest in the microwave region of the radio spectrum.

radioactive decay: Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture  

heat of formation: The standard heat of formation is defined as the amount of heat absorbed or evolved at 25° C (77° F ) and at one atmosphere pressure when one mole of a compound is formed from its constituent elements, each substance being in its normal physical state  

core-mantle: The core–mantle boundary of the Earth lies between the planet's silicate mantle and its liquid iron-nickel outer core. This boundary is located at approximately 2891 km depth beneath the Earth's surface.

dsp73

A model for a​ company's revenue from selling a software package is ​R(p)=-2.5p² + 400​p, where p is the price in dollars of the software. What price will maximize​ revenue? Find the maximum revenue.

Answer: p = $80,  R = $16,000

Step-by-step explanation:

The maximum is the y-value of the Vertex.

Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x:

x=\frac{-b}{2a}

R(p) = -2.5p² + 400

     a= -2.5  b=400

p=\frac{-(400)}{2(-2.5)}

         = \frac{-400}{-5}

        =80

∴ In order to maximize the value, the company will sell the software package for $80

Step 2: Find the maximum by plugging the p-value (above) into the given equation.

R(80) = -2.5(80)² + 400(80)

         = -16,000 + 32,000

         = 16,000
