Chapter 1, Problem 54SYU
To determine

Indicate whether the statement is true or false.

If P=25(1.15)t gives the size of a population in year t, then the population is growing by 15% per year.

5. 2) A country's mid-year total population is 30,000,000. Over the course of the year, there are 220,000 births, and 150,000 deaths. What is its rate of natural increase for the year?
7.8.7 d) in the early 1970s there were approximately 40,000 trees lining the streets of Newton. Today, that number is about 26,000-a 35% loss. The current annual rate of decline is about 650 trees per year. At this rate, if unchecked, public street trees would diminish to approximately 10,000 within a generation (25 years), and in 40 years, public street trees would no longer be part of the Newton landscape.  a-c will be answered in the picture attached a) check the arithmetic that leads to the claimed "35% loss" b) check the arithmetic that leads to a "current annual rate of 650 trees per year". c) check the predictions in the last sentence. are they likely to come to pass? now, using the information in the paragraph and the questions + work shown, answer d) d) write the equation for the linear model implicit in this quotation (use years since 2012 as the independent variable). identify the slope and the intercept, with their units.
Question 5 In 1999, the population of Richmond-Petersburg, Virginia, metropolitan area, was 961,400 and was increasing at a at roughly 9200 people per year. The average annual income in the area was $30,593 per capita, and this average was increasing at about $1400 per year. Use the product rule to estimate the rate at which total personal income was rising in the area at this time. Explain the meaning of each term in the product rule. Question 6 Use Logarithmic differentiation to prove the product rule and the quotient rule. Hint: Let f(x) = A(x)B(x) and g(x) = C(x)/D(x) to start then take the natural log of both sides of each equation and then take the derivative of both sides of the equation. Question 7 Use Logarithmic differentiation to find the derivative of a" for a positive constant a.
