- A car was valued at 38,000 in the year 2007. By 2013, the value had depreciated to 11,000 If the car’s valuecontinues to drop by the same percentage, what willit be worth by 2017 ?arrow_forwardIn the year 1985, a house was valued at 110,000. Bythe year 2005, the value hadappreciated to 145,000. What was the annual growth rate between 1985 and 2005 ? Assume that the value continued to grow by thesame percentage. What was the value of the house inthe year 2010 ?arrow_forwardTable 6 shows the year and the number ofpeople unemployed in a particular city for several years. Determine whether the trend appears linear. If so, and assuming the trend continues, in what year will the number of unemployed reach 5 people?arrow_forward
- the countries of russia and armenia each had populations of 5.5 million in the year 1992.However the relative growth rate of russia was 0.9 % per year , while for armenia it was 3.2 5 per year. assuming exponential growth and the given growth rates, make s projections for each nation in the year 2010 .arrow_forwardAssuming that no withdrawals or deposits are made , write an equation that models the account balance after x yearsarrow_forwardTuberculosis (TB) is one of the top 10 causes of death worldwide. According to the World Health Organization (WHO), deaths from TB have fallen by an average of 1.2% per year between 2000 and 2015. In the year 2000, there were approximately 2.5 million deaths from TB. Part 1. Use the given data to create an exponential decay function to model the number of deaths from TB in terms of years, tt, where t=0 represents the year 2000. Part 2. Use this function to determine the year in which the number of deaths from TB was 2.1 million.arrow_forward
- In 2011 a country had a population of 134 million and a growth rate of -0.79 %. Assuming that this rate remains constant, estimate the population of the country in 2026. .arrow_forwardIn order to save up for Post Secondary, Narissa’s parents invested $4500.00. Their money earns (grows) by 8%, every 2 years. Is this growth or decay? What is the growth or decay rate? How much money will be in the account 5 years from now?arrow_forwardIn each case, state whether the described growth and/or decay is linear or exponential, and explain why. (a) The insect population on land has been decreasing by 9% per decade, but the insectpopulation in water has been increasing by 11% per decade. (b) The typical child grows about 2.6 inches in height each year.arrow_forward
- The next table lists the winners and their prize monies in actual dollars from the Masters Golf Championship from 2006 to 2011. Convert the prize monies into equivalent dollars of 2011. In doing so,(a) Determine the growth rate of the prize money in actual dollars over the fiveyear period.(b) Find the equivalent prize money for each, stated in terms of year 2011 dollars.(c) Determine the growth rate of the prize money in constant (real) dollars.(d) If the current trend continues, what would the expected prize money be in actual dollars for the winner in 2015?arrow_forwardA news article states that the number of people infected with a particular virus has grown by 20% in one week which means 56 people became infected that week. 1. If the growth is linear, how many more people will be infected in one more week? If the growth is exponential, how many more people will be infected in one more week?arrow_forwarduse the growth equationarrow_forward
