- The economic activity of a country is often quantified as the gross domestic product (GDP), which is the sum of private and government consumption, investments, and net exports (the value of exports minus the value of imports). For a developed country such as the United States, economists might see a GDP growth rate of 3% a year as reasonable. However, production and consumption create some pollution. By how much would pollution per dollar of GDP have to decline for pollution levels 50 years from now to be the same as current levels, assuming a 3% annual growth rate of GDP? In 75 years? In 100 years? (Hint: Let the current pollution level be 1 and find out what the future pollution level would be).What is the HDI indicator?A restaurant owner washed 30 kilograms of vegetables, some carrots and some peppers.

- Find the coefficient of x2y3z3 in the expansion of(x + y + z)8.In October 2015, amid rising fears about the security of credit card transactions, financial institutions and businesses made the transition to using chip cards. Unlike the quick swipe of a magnetic stripe on the back of traditional credit and debit cards, chip cards have to be left inside the terminal while the embedded chip verifies the transaction. While there is no consistent method for measuring transaction speed, news agencies report average chip speeds of anywhere from 8 seconds to 13 seconds. The switch to chip readers was precarious, with many businesses taping over the chip card slots in the terminals until the kinks were worked out. Even after a year, some businesses still could not process chips and continued to utilize the magnetic stripe for transactions. Financial institutions thought the additional security benefits of the chips would overshadow the added wait times. Yet a survey conducted by Harbortouch, a leading point-of-sale company, in 2016 showed that nearly four…Given the following: 3 y = (e³)2 This can also be written as: y = e
