Homework 2

1. I will make a prediction of the future of the HIV/AIDS virus. Currently HIV is growing at an exponential rate, increasing as the population of the world increases. It is also predicted by the UN to continue to grow even in 2025 as pictured:



































However, it seems that the rate of growth is diminishing and will eventually level out. Too, the number of people without HIV is rising while the number of people with HIV is lessening in comparison to the number without HIV. This would lead to the conclusion that the rate of people with HIV would eventually even out, creating an S-curve. After the rate eventually flattens out, then possibly the rate would go down, creating a plateau curve. I predict it will be a plateau curve because of medical advances and HIV awareness/ prevention. Since HIV is prevalent around the world, a global effort has ensued to eradicate it. Maybe man will be able to stop it, but its future is uncertain.


2.
a.It would take about 12 years to increase productivity if the number started at 1440. By the twelfth year productivity would be 2897.563.
b. The percent per year increase is 41.421356235% if it doubles every 2 years.
c. The percent per year is 58.7401052% if it doubles every 18 months.
d. Assuming I started out at $1200 in my account, by the end of the 35th year, after interested had been accounted for, I would have doubled my amount to $2400.
