Previous exam questions on area between functions and volumes of solids. 1. Let f(x) = cos(x2) and g(x) = ex‚ for –1.5 ≤ x ≤ 0.5. Find the area of the region enclosed by the graphs of f and g. (Total 6 marks) 2. Let f(x) = Aekx + 3. Part of the graph of f is shown below. The y-intercept is at (0‚ 13). (a) Show that A =10. (2) (b) Given that f(15) = 3.49 (correct to 3 significant figures)‚ find the value of k. (3) (c) (i) Using your value of k‚ find f′(x). (ii) Hence

normal breathing is about 500 mL‚ this volume of air is called the tidal volume.In addition‚Vital capacity is the largest volume of air an individual can move in and out the lungs.Human Lung capacity can be measured in many different ways‚ one way of measuring human lung capacity is by using a ballon.The purpose of this experiment is to determine the vital capacity of your lungs and to understand the relationship between tidal and reserve respiratory volumes.

The Speed of Toy Cars & Measuring Acceleration Introduction: The Speed of Toy Cars & Measuring Acceleration was investigated by using a ticker timer and changing the angle of the ramp. Changing the angle of the ramp affects the speed and acceleration of the trolley. The speed and acceleration of the trolley was determined by using the ticker timer. Aim: The aim of the practical is to investigate the motion and acceleration of a trolley by using a ticker timer and rolling the trolley down a ramp

Volume‚ also referred to as dynamics‚ is one of the most important components of sound. Composers use volume as a way of controlling the emotional content and shape of a piece. It is interesting to note‚ however‚ that early composers did not generally mark their scores with instructions about volume until well into the 17th century‚ but depended upon the musicians to determine the appropriate levels of volume for a specific performance space. Composers started writing indications for dynamic levels

Calculating Beta for Compuware Corporation Financial websites tend to calculate beta on securities differently for publicly traded companies. Beta is merely an estimable measure of an assets’ risk in relation to the market. Because each website has their own underlying assumptions‚ they compute beta to have different values. In some cases‚ the variance in beta is as large as 0.50. To find out what underlying assumptions websites used to compute their betas‚ we performed a series of regression

This particular job did not require us to attend under emergency response‚ this immediately made me feel relaxed and able to focus on my existing knowledge of respiratory pathophysiology. I foolishly had not anticipated any real worries or concerns‚ as it appeared to be a straightforward transportation from GP surgery to hospital. On arrival I was surprised to find the patient unattended and untreated in a room with no HCP present. I felt extremely concerned there had been no monitoring performed

Chapter 11 ARDS INTRODUCTION Acute respiratory distress syndrome (ARDS) - lung inflammation seen at the level of the alveolar capillary membrane with increased vascular permeability. ARDS results in: bilateral pulmonary edema and atelectasis despite no evidence of left heart failure (e.g.‚ normal pulmonary capillary wedge pressure (PCWP). ARDS is present when the ALI results in such severe hypoxia that at the PaO2/FIO2 ratio is 200 mm Hg or less. Approximately 10% to 15% of intensive care
