What is a node in a graph?
Space and AstronomyIn mathematics, and more specifically in graph theory, a vertex (plural vertices) or node is the fundamental unit of which graphs are formed: an undirected graph consists of a set of vertices and a set of edges (unordered pairs of vertices), while a directed graph consists of a set of vertices and a set of
What is a set of ordered pairs in which each input has exactly one output called?
Space and AstronomyWhen each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range. What is a set of ordered pairs is called? A

What do you learn in abstract algebra?
Space and AstronomyRoughly speaking, abstract algebra is the study of what happens when certain properties of number systems are abstracted out; for instance, altering the definitions of the basic arithmetic operations result in a structure known as a ring, so long as the operations are consistent. What have you learned in abstract algebra? Throughout the course they
Why does the Earth takes 365 days to orbit the sun?
Space and AstronomyFor example, the Earth completes one rotation about its axis about every 24 hours, but it completes one revolution around the Sun about every 365 days. Anyway, the basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. Why does the Earth
How do you represent protected in UML?
Space and AstronomyProtected − A protected member is visible from within the class and from the subclasses inherited from this class, but not from outside. It is prefixed by the symbol ‘#’. How can we show protected methods in class diagram? Video quote: In order to represents visibility for visibility for properties and methods in class diagram.
What does the HR diagram compare?
Space and AstronomyThe H-R diagram can be used by scientists to roughly measure how far away a star cluster or galaxy is from Earth. This can be done by comparing the apparent magnitudes of the stars in the cluster to the absolute magnitudes of stars with known distances (or of model stars). What variables does the HR
