Total personal income of the country (in billions of dollars) for selected years from 1958 to 2003 is given in the table. (a) These data can be modeled by an exponential function. Write the equation of this function, with x as the number of years after 1958. (b) If this model is accurate, what will be the country's total personal income in 2008? (c) In what year does the model predict the total personal income will reach $22 trillion? Year Personal Income 1958 408.1 1968 837.7 1978 2314.2 1988 4877.1 1998 8427.3 2003 10,231.3
Optimization
Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the selection of the best element for a given system.
Integration
Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integration and differentiation are inverse operators. Differential equations give a relation between a function and its derivative.
Application of Integration
In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.
Volume
In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects that have length, breadth, and height (or depth).
Area
Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
