should be taking seriously. In this unit 5 learning journal, my concentration would be on Exponential and Logarithmic Functions. In section 1, we are told that among all the functions we have examine so far in this course, the exponential and logarithmic functions are the very ones that mostly impact our daily lives the most (Yakir, 2011). In previous learning, we dealt with various functions which includes terms like x2 or x2=3, that is, terms of the form xp where the base of the term, x, varies but the exponent of each term, p, remains constant. However, in this chapter and unit, we are exploring functions of the form f(x) = bx where the base b is a constant…
of determination of 0,99 and this shows that 99% of the total variation in absorbance can be explained by the linear relationship between absorbance and concentration of the solutions. The other 1% of the total variation of absorbance will remain unexplained. The absolute correlation coefficient (r) is 0,99, which shows a very high correlation. As well as, because r is positive, it shows that absorbance increases as concentration increases. Figure 1 was then used to find out the concentration of…
CONNECTIONS OF LOGARITHMIC FUNCTIONS Logarithm and exponential functions have close relationship and they are inverse function of each other in a way. Before explicitly clarifying this inverse relationship, we should analyze their definitions. Logarithm means, in mathematics, “The exponent that indicates the power to which a base number is raised to produce a given number “2 Exponential function means that “mathematical function in which an independent variable appears in one of the…
a student who would be just sitting there with a blank look on their face and ask them if they understood what they were doing. Without fail the student would say “Yes.” I then followed up by saying, “Okay, show me.”, and the student would proceed to just sit there without a clue. At that point I would start to explain the problem to them and help them work through it, but if I wasn’t there they may not have gotten any help at all and would have continued forward without understanding how to…
If I were asked to determine what Broadway show best represents my life, I would reply simply, Rent. Loosely adapted, my role would be to portray main character Roger Davis . I say this because Rodger and I are similar in the way that we both have a hard time coming up with new and original content. While Rogers issue revolves around his music, my issue is with essays. Ironically, we both know new material is necessary for our occupations, but due to certain circumstances we are both unable to…
One of the reasons why companies expand internationally is to have access to new markets. One such global company, who this writer happens to be very familiar with, is an automobile dealer group called Weins Canada, which is a wholly-owned subsidiary of Weins Group in Japan. The company got its start in 1956 with its first dealership network, called Yokohama Toyopet. The company’s founder, Kanji Miyahara Sr., saw an opportunity to diversify and, potentially, to add exponential growth in…
rate of E. coli growth over 100 minutes in a heated liquid growth medium. The prediction is that the control E. coli culture will grow at a faster rate exponentially over 100 minutes than the experimental bacteria culture. Consequently due to heat application, the experimental bacteria will not grow over the 100 minutes, and will either move into G0 of its cell cycle or will produce descending results as cell death occurs. The null hypothesis for this experiment is that the experimental E. coli…
Francisco Gutierrez 03.03 Linear Functions 1. The equation we have is 2x+3y=1200. The first thing you would need to do in the equation is subtract 2x to both sides. 2x cancels out and now we subtract 2x and 1200. You would end up getting 3y=2x-1200. Then finally, you would have to divide everything by -3. Your final answer for this question is y=-2/3x+400. Your slope is -2/3 and your y-intercept is 400. 2. So we know that our slope is -2/3 and the y-intercept is 400. You have one point on the…
New Balance is moving into a toning market with a pair of attractive shoes that has hidden balance technology. The purpose is to present, “Why walk when you can tone your body”, when you’re simply just walking or even doing your everyday chores. True Balance shoes promises 29% muscle activation and 10% calorie burn. Many women are getting intrigued with the idea of losing weight by these shoes from the percentages, but what if they percentages were lower. Would you still buy them? Even though,…
John Gutmann was one of America’s most distinctive photographers. Gutmann was born in Germany where he became an artist. He later fled Germany due to the Nazi’s because he was a Jew. Gutmann moved to San Francisco and re-established himself as a photojournalist captivating the lives of Americans. He mainly took photographs of people who were imperfect like himself because of his Jewish nationality. Gutmann targeted the poor, circus folk, the gay community and the rich. Two of Gutmann’s works are…
