The timber harvests in the Tongass National Forest in Alaska have decaysed exponentially from 471 million board feet in 1990 to 48 million board feet in 2003.   Predict when the timber harvest will be 10 million board feet.

In the last year, the population of Japan had a decay rate of 0.17% and decreased to 127,484,450. If this rate continues, what will be the population in 7 more years? Round your answer to the nearest whole number.

Personal care aide is an occupation that is growing quickly. Assume​ that, in a certain​ region, there will be a need for 195,686 personal care aides in​ 2024, a growth of about 29​% over 2014 levels. How many personal care aides were there in this region in​ 2014?

Intel co-founder Gordon Moore noticed that the number of transistors on integrated circuits had doubled approximately every two years since their invention. Moore's "law" predicted that this trend will continue into the foreseeable future. The Intel 4004 chip had 2,300 transistors in 1971. How many transistors should be possible in 2019? (Round to nearest billion) billion transistors

If the world's population increased exponentially from 6.081 billion in 2000 to 7.504 billion in 2018 and continued to increase at the same percentage rate from 2018 to 2021, calculate to 2 decimal places what the world's population would have been in 2021.

Population of Texas Texas was the third fastest growing state in the United States in 2016. Texas grew from 25.1 million in 2010 to 26.47 million in 2016. Use an exponential growth model to predict the population of Texas in 2025.

Geologists have estimated that there are 240 billion tons of coal left in the United States. As of now, 1.2 billion tons are mined out each yeara combination of improved technology and higher demand due to increasing population leads mining output to increase by 1.8% each year, how long will the United States coal reserves last?

Diseases tend to spread according to the exponential growth model. In the early days of AIDS, the growth rate was around 190%. In 1983, about 1700 people in the U.S. died of AIDS. If the trend had continued unchecked, how many people would have died from AIDS in 2005?

China had a population in 2008 of about 1.14 billion people.  The populaton is growing by about 1.34% each year.  If this trend continues, when will China's population reach 1.2 billion.
