Concept explainers
Rising Sea Level Marjory Duffin recently purchased a beachfront condominium in New York and is now in a panic, having just seen some disturbing figures about rising sea levels (sea levels as measured in New York relative to the 1900 level).
Year Since 1900 | 0 | 25 | 50 | 75 | 100 | 125 |
Sea Level (mm) | 0 | 60 | 140 | 240 | 310 | 390 |
a. What was the average rate of increase of the sea level over this entire period?
b. During which 25-year interval(s) did the rate of increase of the sea level exceed the average rate?
c. Marjory Duffin’s condominium is about 2 meters above sea level. Using the average rate of change from part (a), estimate how long she has before the sea rises to her condominium.

- Richter Scale Exercise S-1 through S-6 use elementary properties of Richter Scale. If the Richter scale reading of one quake is t units larger than that of a second quake, how do the relative intensities of the quake compare?arrow_forwardRichter Scale Exercise S-1 through S-6 use elementary properties of Richter Scale. If the relative intensity of a quake is multiplied by 10t, how is the Richter scale reading affected?arrow_forwardRound all answers to two decimal places unless otherwise indicated. 24. Timber Stumpage Price The following table shows timber stumpage prices for pine pulpwood in two regions of the American South. Prices are in dollars per ton and were recorded at the start of the indicated year. Year Southeast Mid-Atlantic 2002 6.50 4.00 2005 7.50 6.70 2007 7.00 10.00 a. For the Mid-Atlantic, what is the average rate of change per year in price from 2002 to 2005? b. Use your answers to part a to estimate the price in the Mid-Atlantic region at the start of 2004. The actual price was 6.40 per ton. c. For the southeast, what is the average rate of change per year in price form 2005 to 2007? d. Use your answer to part c to estimate the price in the Southeast at the start of 2008. e. For each region, find the percentage increase in price from 2002 to 2007. f. On the basis of your answer to part e, in the absence of other factors, would an investor in timber be better advised to choose the Southeast or the Mid-Atlantic?arrow_forward
- Running Speed A man is running around a circular track that is 200 m in circumference. An observer uses a stopwatch to record the runners time at the end of each lap, obtaining the data in the following table. aWhat was the mans average speed rate between 68 s and 152 s? bWhat was the mans average speed between 263 s and 412 s? cCalculate the mans speed for each lap. Is he slowing down, speeding up or neither?

An observer uses a stopwatch to record the runner’s time at the each of each lap, obtaining the data in the following table. (a) What was the man’s average speed (rate) between 68 s and 152 s? (b) What was the man’s average speed between 263 s and 412 s? (c) Calculate the man’s speed for cadi lap, Is he slowing down, speeding up, or neither?arrow_forwardContinued This is a continuation of Exercise 13. As we saw earlier, the stock turnover rate of an item is the number of times that the average inventory of the item needs to be replaced as a result of sales in a given time period. Suppose that a hardware store sells 80 shovels each year. a. Suppose that the hardware store maintains an average inventory of 5 shovels. What is the annual stock turnover rate for the shovels? How is this related to the yearly number of orders to the wholesaler needed to restock inventory? b. What would he the annual stock turnover rate if the store maintained an average inventory of 20 shovels? c. Write a formula expressing the annual stock turnover rate as a function of the average inventory of shovels, identify the function and the variable, and state the units.arrow_forward
