Answer: you do 9.9 squared and then you times it by 1.79 so you get =5.632103515 so then you estimate it to 5.6
Step-by-step explanation:
The average rate of change between day 9 and day 14 is 20.
%/100 = is / of
7 is what percent of 30
is = 7
of = 30
% = x
now sub into the formula
x/100 = 7/30
cross multiply
(30)(x) = (7)(100)
30x = 700
x = 700/30
x = 23 1/3% or 23.33%
The equation is y=2,700x+70,000
the x represents the number of years the 2,700 represents the numbers of people new each year and the 70,000 represents the number of people started with in the town in 2003.
