Question 6:

In thousands, the population can be modeled by
P = 80*1.04^(t-2003)
where t is the year number
Finding answers to the questions can be done graphically.
a) In 2015, the population will be about
128,083.b) The population will be 240,000 in
2031.
_____
a) p = 80,000*1.04^12
b) t = 2003+log(3)/log(1.04)
Answer:
7.8 (when I calculated I rounded to tenths so the actual answer might be a little bit different)
Step-by-step explanation:
the area of a circle is radius squared so
153.86= radius squared
sqaure root both sides and you get 12.4 =radius
divide both sides by pi and you get 3.9 which is the radius
the diameter is double the radius which is 3.9 *2 which is 7.8 :) hope this helped.
