Is a simple graph connected?
Space and AstronomyA simple graph may be either connected or disconnected. Unless stated otherwise, the unqualified term “graph” usually refers to a simple graph. A simple graph with multiple edges is sometimes called a multigraph (Skiena 1990, p. 89). Does simple graph need to be connected? A simple graph doesn’t need to be connected. If a vertex

How are large distances in space measured?
Space and AstronomyBecause space is so big, many astronomers do not like to say how far away things are using miles or kilometers. Instead, we use a measurement that we call a parsec. Remember Alpha Centauri, the closest star? It is 1.347 parsecs, or 41,560,000,000,000 (or 41.56 trillion) kilometers away. What is used to measure large distances

What is a trapezoid 1st grade?
Space and AstronomyTrapezoids are an exciting and challenging new shape that your student will start to learn about around first grade. Trapezoids are defined as 4-sided flat shapes with straight sides where at least one pair of those opposite sides are parallel. What is a trapezoid simple definition? : a flat geometric figure with four sides but

How do you find the actual size of a specimen?
Space and AstronomyCalculation of Actual Size: To calculate the actual size of a magnified specimen, the equation is simply rearranged: Actual Size = Image size (with ruler) ÷ Magnification. How do you find the actual size of a specimen microscope? Estimating the Size of the Specimen Under Observation To estimate the size of an object seen with

What are the four ways to represent a function?
Space and AstronomyKey Takeaways A function can be represented verbally. For example, the circumference of a square is four times one of its sides. A function can be represented algebraically. For example, 3x+6 3 x + 6 . A function can be represented numerically. A function can be represented graphically. What are the 4 ways a function

What are like terms in algebra?
Space and AstronomyIn algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.

What is the use of a cross staff?
Space and AstronomyIn navigation the instrument is also called a cross-staff and was used to determine angles, for instance the angle between the horizon and Polaris or the sun to determine a vessel’s latitude, or the angle between the top and bottom of an object to determine the distance to said object if its height is known,
