Use the properties of logarithms to write the following expression as one logarithm. Logs logr + 8logr s − 3logr t mc001-1. Jpg
vagabundo [1.1K]

In this exercise we have to use the properties of the logarithm to write it in one way, like this:

log(r+s)(rs)^8/(rt)^3

From these  recalling some properties of the logarithm, we find that:

  • When the logarithm is equal to the base, the logarithm will always be equal to 1.
  • Logarithm of any base, whose logarithm is equal to 1, will always have the result equal to 0.
  • Two logarithms with the same base are equal when the logarithms are also equal.

given the equation as:

log(s)log(r)+8log(rs)-3log(rt)\\log(s+r)+8log(rs)-3log(rt)\\logg(r+s)(rs)^8/(rt)^3

Explain why understanding the process of cause and effect might be important to someone studying the environment.
Rina8888 [55]

Environment is something very important today, because it is becoming more and more polluted. People do harm without being aware that they destroy the world. People just want more and more money and more and more destruction, which is definitely the cause, yet people do not know the effect that it can cause. Without explaining the effect that pollution can cause, today's environment cannot be explained. Shortly, by being greedy (the cause),  we destroy our habitat (the effect)

Why is the history of Psychology important???
LiRa [457]

Answer:

Today, psychology is defined as "the scientific study of behavior and mental processes." Philosophical interest in the human mind and behavior dates back to the ancient civilizations of Egypt, Persia, Greece, China, and India.

Psychology was a branch of the domain of philosophy until the 1860s, when it developed as an independent scientific discipline in Germany.

Psychology as a field of experimental study began in 1854, in Leipzig Germany, when Gustav Fechner created the first theory of how judgments about sensory experiences are made and how to experiment on them. Fechner's theory, recognized today as Signal Detection Theory foreshadowed the development of statistical theories of comparative judgment and thousands of experiments based on his ideas (Link, S. W. Psychological Science, 1995). Later, 1879,Wilhelm Wundt founded in Leipzig, Germany, the first Psychological laboratory dedicated exclusively to psychological research in Germany. Wundt was also the first person to refer to himself as a psychologist (a notable precursor of Wundt was Ferdinand Ueberwasser (1752-1812) who designated himself Professor of Empirical Psychology and Logic in 1783 and gave lectures on empirical psychology at the Old University of Münster, Germany. Other important early contributors to the field include Hermann Ebbinghaus (a pioneer in the study of memory), William James (the American father of pragmatism), and Ivan Pavlov (who developed the procedures associated with classical conditioning).
