domain‚ you divide the total amount of material by the number of x’s. 180 is the total amount of material and there are 3 x’s. So divide 180 by 3. The answer is 60. So the domain is (0‚ 60). To find the dimensions that yield maximum area‚ on the calculator press the y= button and type in the final area equation we got‚ which is 180x – 3x^2. Then before you graph‚ you press the window button and enter the domain in the Xmin and Xmax slots. So it would look like Xmin = 0 and Xmax = 60. You just leave

Cancel out k the m‚ and we have the general expression n ‚ which is indeed in the form p . q Now‚ to make sure this expression worked‚ I tested by using it to find the following two terms.

diminishing fossil fuels In 1977‚ the President of the United States of America‚ Jimmy Carter‚ advocated for the use of alternative energy to the American people “because we are now running out of gas and oil‚ we must prepare quickly to strict conservation [of fossil fuels] and to the use of coal and permanent renewable energy sources‚ like solar power.” More than thirty years later his announcement still rings true and is relevant. In fact‚ the current situation of non-renewable fuels is worse than

Chapter 1 Review Questions 2. What is the most important difference between a computer and a calculator? a. Computers contain a programmable microprocessor that understands data‚ which helps‚ make important decisions. A calculator can only be used to perform numerical mathematical calculations. 3. How are computers today similar to those from World War II? How are they different? a. The similarity between computers of WWII and today is that they computed large data and removed the human error factor

Fossil Fuel Consumption‚ CO2 and Its Impact on Global Climate Background: At the beginning of human history‚ we had to satisfy our energy needs (for food‚ heat and movement) by using our own muscle power and gathering or hunting naturally available plants‚ animals and wood. Each stage in the evolution of human society (the development of farming‚ domestication of animals‚ harnessing of wind and water power) increased the average per capita energy use‚ but it was the Industrial Revolution and the

1/ what is the essential difference between alternative energies (AE) and fossil fuels? Alternative energies will not have a lot of pollution‚ but fossil fuels will cause some pollution of the environment. Some fossil fuels causes environmental pollution‚ for example‚ global climate change‚ a lot of carbon dioxide cause the greenhouse effect‚ acid rain emissions of harmful gases cause serious pollution to the atmosphere. 2/ name the AE that you have chosen to research.

| Ethanol Fuel Production from Banana Waste Peelings | CHAPTER 1 INTRODUCTION Due to the modernization to our country‚ there were new things that are added in the basic necessities of an individual‚ one of this is fuel. Since fuel can be afford in a high price‚ some people afford fuel. To resolve this problem‚ we need to find abundant and renewable source of fuel that is low cost. The project entitled “ETHANOL FUEL from BANANA PEELINGS” can help to solve this problem. This project will

How Modern Transport Fuels Effect our Environment Why is looking at alternate fuels important? There are several reasons‚ but the most important reason is that air pollution kills in the neighborhood of 3 million people every year and air pollution affects more than 1 billion people in a negative way. That ’s over 1/6 of the earths population being harmed by air pollution‚ that ’s a trend that cannot continue without extreme repercussions to everyone on the planet. Granted‚ air

“The use of fossil fuels‚ such as coal and oil‚ belongs to the past.” For the time being‚ the world is mostly dependent on the use of fossil fuels. All the infrastructure is fossil fuel based. i.e. if the world runs out of fossil fuels now‚ there won’t be any alternative energy source to power the entire world. Fossil fuels are usually found in rock formations containing fossils from decomposed animals and plants. The formation of fossil fuels happens in the course of hundreds of millions of years
