Section 9.1: Exercises 6, 12, 20, 28, 32, 50 6.) Explain why each graph is that of a function. * Each graph is that of a function because at each point in a graph we get a value for y corresponding to a value for x. This is just the pictorial reflection of what we get in case of a function. Solve each system by substitution 12.) Solution * 2x + y = 5 * y = 5- 2x Substituting in first equation 4x – 5y = -11 4x – 5(5-2x) = -11 4x – 25 + 10x = -11 14 x =

Questions: 1. How should Jonathan describe the rationale of the dividend discount model (DDM) and demonstrate its use in calculating the justifiable price of common stock? The dividend discount model (DDM) states that the price of the stock at a given time is: Po= Div1/ (r-g) where; Po= value of the stock, Div1=Dividend distributed the following year, r= required rate of return, g=growth rate of dividends, the growth rate “g” is assumed to be constant. The value of the stock can also be found

Week 7 DQ The best way to determine the number of solutions a quadratic equation has is to graph the equation. The number of times the equation crosses the x-axis is the number of real solutions the equation will have. If you are given the solutions (roots) p and q of a quadratic equation then you can find the equation by plugging p and q into the formula (x-p)(x-q) = 0. It is possible for two quadratic equations to have the same solutions. An example of that would be -x^2 + 4 and x^2 - 4. Each

A relational database is a collection of relations or tables. The rows of a table in a relational database are known as tuples and each column of a table is called an attribute. By definition, a relation becomes a set of tuples having the same attributes. Operations, which can be performed on the relations are select, project and join. The join operation combines the relations. The select queries are used for data retrieval, and the project operation identifies attributes. The information of the
