Global Warming: An exponential threat We currently live in a highly globalized world from every point of view (technological‚ scientific‚ cultural‚ economic‚ communicative‚ etc.) hence‚ one of the most negative effects that generated globalization has been the growing ecological imbalance that has harmed the planet. The global warming has become of the most dangerous threats and challenges to face in the 21st century. Many companies and factories are currently one of the main factors which

the reaction time if you had reduced the hydrochloric acid by half? Explain why. 4. What should you have learned about reaction rates? 1. The kind of graph that resulted when I plotted the mL of thiosulfate against the time in seconds was an exponential decay. 2. The graph tells us that the rate of reaction increases when there is more thiosulfate as the reaction took more time when there was less thiosulfate. This is shown on the graph by the increasing volume of thiosulfate corresponded to a

are modeled by functions. Precalculus is essentially the study of functions‚ with a few other related topics that supplement the study of functions and prepare students for calculus. In this text we’ll concern ourselves first with learning about general functions‚ and later with certain types of common functions with special properties‚ like polynomial‚ exponential‚ logarithmic‚ and trigonometric functions. First‚ it is of critical importance to understand exactly what a function is. In the following

The next phase in the bacteria ’s life cycle is the log (logarithmic or exponential) phase. At this point‚ the bacteria begin replicating swiftly. Once the culture reaches high densities‚ their living space and nutrients begin to deplete‚ and the toxicity levels begin to increase (Doyle). Due to this rapid growth‚ the next

Mass Index (BMI) is a comparison between a person’s height (in meters) and weight (in kilograms) in order to determine whether one is overweight or underweight based on their height. The goal of this portfolio is to prove of disprove how BMI as a function of Age (years) for girls living in the USA in 2000 can be modeled using one or more mathematical equations.
