Why do we use functions in math?
Space and AstronomyBecause we continually make theories about dependencies between quantities in nature and society, functions are important tools in the construction of mathematical models. In school mathematics, functions usually have numerical inputs and outputs and are often defined by an algebraic expression. What are functions in math used for? Mathematical Functions A mathematical function is a

How do you take care of Picasso calla lilies?
Space and AstronomyThey prefer rich garden soil in full sun or partial shade. Hardy in zones 8-10; in other zones, treat them as an annual. Bring the pots indoors over winter, or lift and store the bulbs in a cool dry place for re-planting in the spring. How long do potted calla lilies last? approximately four months

In what ways is Venus most similar to Earth?
Space and AstronomyVenus is often referred to as our sister planet because of similarities in size, mass, density and volume. It is believed that both planets share a common origin forming at the same time out of a condensing nebulosity around 4.5 billion years ago. In what ways is Venus most similar to Earth quizlet? In what

How do you find the domain and range of input and output?
Space and AstronomyHow do you find the range of inputs and outputs? Video quote: They'll just put like a capital D there to stand for domain. And that's kind of the format they want if they said please find the range well keep in mind the range is just the list of all the Y's. What is

What is Hyp adj?
Space and AstronomyThe cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp). (1) Memorize: sine = (opposite side) / hypotenuse. cosine = (adjacent side) / hypotenuse. How do you find Hyp and adj? Video quote: Since they're looking for the hypotenuse. We can then say that H is equal to the opposite side divided

When a solution set is empty?
Space and AstronomyIf an equation has no solutions, its solution set is the empty set or null set–a set with no members, denoted Ø. For example, the solution set to x2 = – 9 is Ø, because no number, when squared, is equal to a negative number. What does it mean for a set to be empty?

Where is WMAP located?
Space and AstronomyWMAP was launched June 30, 2001, and was positioned near the second Lagrangian point (L2), a gravitational balance point between Earth and the Sun and 1.5 million km (0.9 million miles) opposite the Sun from Earth. How much does the WMAP cost? just $150 million Considering the impact of its results, WMAP was a fairly

Is trigonometric form the same as polar form?
Space and AstronomyTrigonometric or Polar Form of a Complex Number (r cis θ) Here we will use that basic conversion to rewrite z = a + bi in another (sometimes more convenient) form that is based on the polar conversion. This new form is called the trigonometric form of a complex number. How do you convert trigonometric

How many years ago did Galileo discover Jupiter’s moons?
Space and AstronomyJan 7, 1610 CE: Galileo Discovers Jupiter’s Moons. On January 7, 1610, Italian astronomer Galileo Galilei discovered, using a homemade telescope, four moons orbiting the planet Jupiter. What did Galileo used his telescope for? Galileo pioneered the use of the telescope for observing the night sky. His discoveries undermined traditional ideas about a perfect and

What is a measure of relative distance in space?
Space and AstronomyThe astronomical unit is used primarily for measuring distances within the Solar System or around other stars. It is also a fundamental component in the definition of another unit of astronomical length, the parsec. What is relative distance in space? Relative distance means how far apart the planets are when compared to each other and
