(a)
To calculate: The instantaneous rate of change of the GDP in 2005 and 2015 and interpret it. The table shows U.S. gross domestic product (GDP) in billions of dollars for selected years from 2000 to 2070. Assume that the GDP can be modeled with the function
(b)
To calculate: The average rate of change of the GDP from 2005 to 2015 using the data given. The table shows U.S. gross domestic product (GDP) in billions of dollars for selected years from 2000 to 2070. Assume that the GDP can be modeled with the function
(c)
The wellness of average rate of change of the GDP from 2005 to 2015 approximates the instantaneous rate of change of GDP in 2020. The table shows U.S. gross domestic product (GDP) in billions of dollars for selected years from 2000 to 2070. Assume that the GDP can be modeled with the function

- Tax Table Here are selected entries from the 2014 tax table that show the federal income tax owed by those married and filing jointly. The taxable income and the tax are both in dollars. Taxable income Tax 72, 000 9896 72, 200 9926 72, 400 9956 72, 600 9986 72, 800 10, 016 73, 000 10, 046 73, 200 10, 076 73, 400 10, 106 73, 600 10, 136 73, 800 10, 169 74, 000 10, 219 74, 200 10, 269 Over what two parts of this table is the tax a linear function of the taxable income? Find formulas for both linear functions, and explain in practical terms what the slopes mean.arrow_forwardDVD Player Sales The table shows the number of DVD players sold in a small electronics store in the years 2003-2013. Year DVD players sold 2003 495 2004 513 2005 410 2006 402 2007 520 2008 580 2009 631 2010 719 2011 624 2012 582 2013 635 aWhat was the average rate of change of sales between 2003 and 2013? bWhat was the average rate of change of sales between 2003 and 2004? cWhat was the average rate of change of sales between 2004 and 2005? dBetween which two successive years did DVD player sales increase most quickly? Decrease most quickly?arrow_forwardPopulation Genetics In the study of population genetics, an important measure of inbreeding is the proportion of homozygous genotypesthat is, instances in which the two alleles carried at a particular site on an individuals chromosomes are both the same. For population in which blood-related individual mate, them is a higher than expected frequency of homozygous individuals. Examples of such populations include endangered or rare species, selectively bred breeds, and isolated populations. in general. the frequency of homozygous children from mating of blood-related parents is greater than that for children from unrelated parents Measured over a large number of generations, the proportion of heterozygous genotypesthat is, nonhomozygous genotypeschanges by a constant factor 1 from generation to generation. The factor 1 is a number between 0 and 1. If 1=0.75, for example then the proportion of heterozygous individuals in the population decreases by 25 in each generation In this case, after 10 generations, the proportion of heterozygous individuals in the population decreases by 94.37, since 0.7510=0.0563, or 5.63. In other words, 94.37 of the population is homozygous. For specific types of matings, the proportion of heterozygous genotypes can be related to that of previous generations and is found from an equation. For mating between siblings 1 can be determined as the largest value of for which 2=12+14. This equation comes from carefully accounting for the genotypes for the present generation the 2 term in terms of those previous two generations represented by for the parents generation and by the constant term of the grandparents generation. a Find both solutions to the quadratic equation above and identify which is 1 use a horizontal span of 1 to 1 in this exercise and the following exercise. b After 5 generations, what proportion of the population will be homozygous? c After 20 generations, what proportion of the population will be homozygous?arrow_forward
