What is a visibility symbol in UML?
Space and AstronomyIn object-oriented design, there is a notation of visibility for attributes and operations. UML identifies four types of visibility: public, protected, private, and package. The +, -, # and ~ symbols before an attribute and operation name in a class denote the visibility of the attribute and operation. Which symbol is used for public visibility?
What are spreading calipers used for?
Space and AstronomySmall Spreading Caliper (pointed ends) The GPM Small Spreading Caliper with pointed ends provides accurate measurement of short distances between two points, where one or both points may not be on a flat surface. This caliper is most commonly used for craniometry and cephalometry. How do you read a spreading brake caliper? Video quote: The
What is a division number model?
Space and AstronomyA repeated subtraction or measurement model of division is a situation where the dividend represents. the number of objects and the divisor represents the size of each group. For example, in the problem. 12÷4, the 12 stands for the number of objects and the 4 stands for the size of each group. How do you
What is discrete structure function?
Space and AstronomyAdvertisements. A Function assigns to each element of a set, exactly one element of a related set. Functions find their application in various fields like representation of the computational complexity of algorithms, counting objects, study of sequences and strings, to name a few. What is meant by discrete structure? discrete structure A set of discrete
What is a non congruent shape?
Space and Astronomythe sides, and noncongruent means “not congruent,” that is, not the same shape. (Shapes that are reflected and rotated and translated copies of each other are congruent shapes.) So we want triangles that look fundamentally different. What is a non example of congruent? Video quote: So for example this shape is congruent to this shape
What is the radius of a 20 ft circle?
Space and AstronomyWhat is the radius if circumference is 20? Answer. Answer: r=10π cm. What is the area of a 20 radius circle? 1 Answer. Area = 1256 inches squared. What is the radius of 18 ft? Dean R. The diameter is twice the radius, so would be 36 feet. How do you find an radius of
What is the derivative of a log?
Space and AstronomyThe derivative of log x (base 10) is 1/(x ln 10). If the log has a base “a”, then its derivative is 1/(x ln a). i.e., d/dx(logₐ x) = 1/(x ln a). How do you derive the derivative of a log? To find the derivative of other logarithmic functions, you must use the change of
What solid figure is a globe?
Space and AstronomysphereA sphere is known to be a solid figure which is round and it basically has the shape of a ball. For example, basketball is also a sphere. Another example of a sphere can be the earth we are standing on! When we look at a globe, we can see that the earth is three-dimensional
What is a common vertex?
Space and AstronomyA common vertex is a vertex that is shared by two angles. A vertex is the point at the intersection of any two linear constructions. What is a common vertex and side? Adjacent angles are two angles that have a common vertex and a common side but do not overlap. In the figure, ∠1 and
Who invented the armillary sphere?
Space and AstronomyWhere did the armillary sphere originate? The armillary sphere originated in ancient Greece, where it was used primarily as a teaching instrument, although bigger versions were used as observational tools. When was armillary sphere invented? In the west, the armillary sphere was invented by the Greek astronomer Eratosthenes in approximately 225 BCE; however, it was
