Mathematics Assignment Math Problem Example | Topics and Well Written Essays - 1000 words
Mathematics Assignment - Math Problem Example 1 m3 = 100 cm3 = 0.86 tonnes Then, divide both sides by 10 10 Cubic cms = 0.086 tonnes (b) What volume of soil weighs 3 kg 1 ton = 1000 kg Then, 0.86 tonnes = 860 kg = 1 m3 So, 1 m3 = 860 kg Multiply both sides by 3/860 3/860 m3 = (3*860) / 860 kg 0.0035 m3 = 3 kg 14. If 10 men take 3 days to complete a task (a) How long will it take 6 men to complete the task 10*3 = 6*x 30/6 = x = 5 (b) If the task is to be completed in two days how many men are required 10*3 = x*2 X = 30/2 = 15 15. Draw the graph of 5x + 2y 10 = 0 and determine the x and y intercepts When x=0, 5(0) + 2y = 10 Y= 10/2 = 5 (x,y) = (0,5) Similarly, when y=0. 5x + 2(0) = 10 X = 10/5 = 2 (x,y) = (2,0) 16. The distance travelled by a train and the corresponding times are given by Time, hrs 0 0.5 1.5 2.5 Distance, kms 0 38 114 190 Plot the graph of distance as a function of time and determine the equation of the line. Equation of the line, y = mx +c Where, c = y-intercept & m = slope of the line = here, as the graph shows c = 0, whereas, let us consider (0,0) and (0.5,38) to determine m. m = (38 - 0) / (0.5 - 0) = 76 So, the equation of the line is: y = 76x + 0 or y = 76x 17. A ball is thrown upward with an initial velocity 55 m/sec. The speed of the ball decreases uniformly with time and after 5 secs its velocity is 6 m/sec. (a) Determine the equation relating the velocity of the ball and time. Here, there are 2 coordinates given, i.e. (55,0) and (6,5) considering time is plotted on the y-axis. As per the graph in part b, c (y-intercept) = 5.6 and m = (5-0)/(6-55) = -5/49 Therefore, the equation will be, + 5.6 Or 49y +5x = 274.4 (b) Draw the graph of this equation. (c) Determine the time at which the... The negative velocity in this example would be a hypothetical state to achieve. The equation for such a case will be bound by constraints, ensuring no negative values can be put in for time and velocity.

Video Case Study Write ups - Essay Example In this video, the host focused on gathering information from various sets of masses like peasants, millionaires, drag queens, students and many others. The central theme of the video is that as compared to the previous decades, the modern day Chinese masses is interested in graduating to a better life by making more money through their own method of working hard. It is interesting to point out that the video documentary brings into notice the relation of Chinese prosperity and American policy changes in the business front. Many well known companies like Ethan Allen, Wal-Mart as well as other well known retailers of the US market have focused on outsourcing their production lines in order to cut costs and generate high profit margins over the years. While this in turn promotes job loss in the American shores, yet it provides generates jobs as well as related economic prosperity in the Chinese market
