upper and lower extremes of 3 and 18). Comment on how
accurate
this is.
Question 3

(e) The increase in repayment per month, should there be a 1%
increase in interest rates.

a loan (for his part) of $100,000
over 10 years at 6% pa.
Question 4
To make a rectangular grid of 2 rows of 3 squares requires 17
matches.
(a) How many matches would you need to make rectangular
grids of m
rows of n squares?
(b) Write down a formula relating M, the number of matches

5. and n for an n x n square.
(c) Extend your analysis for the equilateral triangle .
(d) Extend your analysis for hexagons.

The Internet is a powerful tool that provides the ability to
monitor natural phenomena and disasters that happen all over
planet Earth.
In this assignment, you will research resources available on the
Internet for monitoring natural phenomena including
earthquakes, volcanoes, tsunamis, global climate, and weather.
Based on your research, do the following:
First, identify a minimum of three different natural phenomena
that are typically responsible for natural disasters. Analyze the
potential impact of these disasters.
Second, analyze how these phenomenon are monitored, or not,
via the Internet. Critique available Web sites, which publicly

6. display up-to-date monitored information related to each of the
natural phenomena you have identified. Focus on the following
aspects:
· Geography
· What parts of the world are potentially affected by these
phenomena? Specifically identify the countries.
· Resources
· What kinds of resources are allocated toward monitoring these
phenomena and why?
· What types of Web resources monitor the phenomena and
provide up-to-date information about them?
· What kinds of technology are involved in monitoring the
phenomena?
· Politics
· What political ramifications would this disaster-preparedness
technology cause between more-developed countries and less-
developed countries?
· What kinds of issues could this technology cause between
less-developed countries?
· Economics
· How would this technology directly impact the economies of
those countries that have the technology versus those countries
that do not?
· Do you predict any indirect impacts? What current evidence
supports your position?
· Disaster Preparedness
· What types of systems are in place in terms of disaster
preparedness related to these monitored phenomena?
Last, summarize your findings. Evaluate how this technology
will impact the future of humanity, both positively and
negatively. Be sure to consider the political and economic
issues discussed in your future predictions.
