Ecology You can find data about air pollution and other environmental issues on the U.S. Environmental Protection Agency (EPA) web site, www.epa.gov.
Ellis and Gabriela want to use the garbage-disposal data to help decide whether people are recycling more or less than they used to.
a. What is the percentage increase in tons of waste recycled or com- posted in 2000 compared to 1960?
b. Graph the amount of waste recycled or composted over the years 1960–2000.
c. Ellis argued that the answer to Part a and the graph from Part b show that recycling has improved a great deal in the last few decades. Do you agree? Why or why not?
d. Gabriela argued that they should compute a ratio for each year: the amount of waste recycled or composted to the total amount of waste generated. Make a table showing this ratio, as a decimal, for each year in the original table. Then graph the ratios over the 1960–2000 period.
e. What does your graph from Part d tell you about whether people are recycling more or less than they used to?
No nets of exercise. 39 part A. The total pollution is just the integral of pollution function from their role to 100 and four. And first we need to calculate the anti derivative function of the pollution function. And it is this expression. We can verify that the directive of this function is rarely the pollution function. The derivative activity is one for the this part. We use the chain rule, the derivative of sine access codes, I next and the relative of a pie to over 26 pi over 26. Multiplying 26 or pie gives one next, which is a substitute, 100 and 40 0 into this expression, and we get the federal answer, which is 100 and full for Barbie. He wants the pollution from the 13th week 2 50 seconds week and it's just the integral of the production function. From 13 52 the anti derivative is the same, and we just substitute 13 and 52 to this anti derivative. And it gives us this result which has 39 miners, 26 over pie and the numerical approximation. All these value is 13 points 7 to 4 for Percy. This is a graph of the production function and the pollution from the 13th week to 52nd week is just, uh, error between this promotion function from 13 to 52 and it's just the area of this right shaded area.
Mhm. The total pollution is just the integral of the pollution function. Hence for party who just need to evaluate the integral of the promotion function from 0 to 104. And we know that the anti derivative of the provisions function is this and hence which is the need to evaluate the anti derivative of that 104 and zero. And then calculate their difference. The anti derivative. We had a hand very and four is the hand very uniform. And It's that at 00. Hence their derogative as 100 and awful. And for part B. We're just evaluate the integral of the production function from 13 to 52. And similar. They valid the anti derivative that 52 13 and then calculate their difference. The value of the anti direct every other 52 years 52. And the anti derivative 13 as 13 plus 26 or part. And then their difference is 39 Miners 26 or part. And the approximate value is 13 30.7- four. And for percy the answer probie is just in the area of this shaded region.
S 02 is a colorless, tasteless gas that is found in the environment from machinery is such as cars, it enters the atmosphere and comes back down as acid rain.
We were looking to sketch out the liver structure off dinosaur. So fight this is drawn below and were identifying our bonding angle, which is about 104.5 degrees due to the lump. As so the remaining bond angles associated without me. Foul groups are approximately 109.5. So now we're using electro negativity is to discuss side where the partial positive and negative charges are in the molecule where we have a delta minus on our sofa. It's more Electra negative on carbon which have associative doubt a positive charge. So the sulfur atom does have a slight partial negative charge on the carbons have a slight partial positive charge. The molecule is bent on considered polar. So yes, it is polar. Lastly, the mean seawater concentration of G. M s and the sea is 2.7, not a mullah, which is abbreviated N. M. So how maney molecules of GMs are present in one meters cube off seawater. And our answer here is 1.6 times 10 to the 18 molecules
