Rational Equations Rational equations can be used to get a general idea about the rate at which a job can be completed. This can be really useful for business owners and other areas of daily life. Here is an example: Scenario: Sue can paint the garage in 4 hours and Joe has carpal tunnel so he is slower and can paint the same garage in 6 hours. How long (number of hours) will it take Sue and Joe to paint the garage if they work together? Solution: Sue can paint of the garage in 1 hour. Joe

The reason why the Drake Equation is not a successful science is because it would be impossible to calculate some of the elements in the equation. The elements would take too long to get an accurate sample to give a scientifically sound explanation. For instance how would you calculate fi (the fraction of intelligent life forms)‚ how do you define intelligent? Is intelligent like you and I‚ is it like a bird or a rat‚ could it be a plant? There is no way to truly determine what counts and doesn’t

of operations is a rule to clarify confusion that may occur in an equation that has multiple different operations. This rule of Order of Operations states we must solve a complex equation by complete the operations in this order: Parenthesis‚ Exponents‚ Multiplication‚ Division‚ Addition‚ and Subtraction. We can remember this by this mnemonic: Pink‚ Eyes‚ May‚ Doubt‚ Anyone’s‚ Style. *** This will happen if we take this equation and NOT follow the Order of Operation*** 4+ 2 x 3 = If I did not

memory. Jia Zhangke‚ Lou Ye‚ and Jiang Wen offer a subtle and fascinating account of the cinematic representation of the problem of memory. Since the inception of the camera‚ filmmakers have evolved motion pictures into not simply a reflection but a crucial indicator of human experience‚ especially our experience of fleeting time and of the current moment. It could be argued that all narrative representation is‚ in some way‚ a flashback. The stories created by filmmakers‚ whether illusory or realistic

on Transactional Model 8-24-2010 The Transactional Model of Communication: An Equation The transactional model of communication is an infinitely long‚ incredibly complex ‘web’ of perceptions‚ actions‚ predictions‚ and reactions that perpetuate/transfer among people. The transactional model of communication can be compared to a simple but extensive equation. To avoid the subjectivity about numbers and their representation of quantities and physical properties in math‚ I’ll be using (#) to represent
