IB Mathematics Standard Level Portfolio Assignment Task I Tide Modeling Kelvin Kwok In this modeling assignment‚ I will develop a model function for the relationship between time of day and the height of the tide. I will first show the data in a table form copied from the assignment sheet. Then I will use the data to construct a scatter graph of time against height‚ then I will develop a function that models the behavior noted in the graph analytically‚ and describe any variables‚ parameters

1. Executive Summary Internet becomes one of the most important aspects in communication. Not only for browsing‚ do research‚ communicating‚ but also playing game and access social media. Internet already becomes a lifestyle‚ without it some people will get frustrated. Warnet are very popular in Indonesia‚ for they allow those who cannot afford computers the advantage of being online and participating in global communications‚" Rudy Rusdiah‚ the chairman of the Indonesian Internet Kiosks Association

Background Theory Photosynthesis: Plants require water from the soil‚ sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis‚ carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen‚ which is given off as a by-product. Generally‚ as sunlight increases in intensity‚ the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables

treatment facilities use this components to disinfect the water. It is stated that the fluoride may damage the teeth Other reason why it is stated that tap water in the United sates is not save is due to the lead‚ aluminum and heavy metals that pass trough your tap water from the corrosion of the pipes and plumbing‚ since During this research I came to conclude that there are several methods that the United States uses for having a clean and treatable tap water. United states has one of the best cleaning

Of course‚ we live in an imperfect world and not all surfaces are smooth. When light strikes a rough surface‚ incoming light rays reflect at all sorts of angles because the surface is uneven. This scattering occurs in many of the objects we encounter every day. The surface of paper is a good example. You can see just how rough it is if you peer at it under a microscope. When light hits paper‚ the waves are reflected in all directions. This is what makes paper so incredibly useful -- you can read

carefully with a thermometer until a constant temperature is reached. Record the volume of water and the constant initial temperature of the water on your data table. Place a plastic measuring trough on top of the digital balance‚ and then zero the balance (press the tare button) so that the mass of the trough will be “ignored” and will not be added to the total mass measured by the balance. Measure out approximately three to five scoops of solid sodium hydroxide and record the mass to your data table

cannibalization effectively. Further more‚ using ODI contact lens can also reduce the farmer’s feed cost and bring greater feeding efficiency. A debeaked chicken can only eat if the feed in the trough is at least 3/8” deep. Chicken with ODI contact lens will not have that kind of problem and can eat feed in the trough at 2” or 1” deep which can save the farmers a lot of money on the feed cost. The red tint of the ODI contact lens‚ causing a red-colored environment for the chickens‚ will affects the chicken’s
