Answer:
i think the 2nd one is correct .. i have not fluent in english to explain the answer.
F(x)=(2/3)x^1.5
The centroid position along the x-axis can be obtained by
integrating the function * x to get the moment about the y-axis,
then divide by the area of the graph,
all between x=0 to x=3.5m.
Expressed mathematically,
x_bar=(∫f(x)*x dx )/(∫ f(x) dx limits are between x=0 and x=3.5m
=15.278 m^3 / 6.1113 m^2
=2.500 m
Answer:
In 2003, the population was 59000 and the population has been growing by 1,700 people each year.
A.
The equation will be:
59000+1700x = (population 'x' years after 2003)
For x, you plug in the amount of years after 2003.
Like if it is the year 2003, the population is 
= 59000
when it is year 2005, the population is 
= 62400
B.
The town's population in 2007 will be :
Population = 65800
C.
=> 
x = 11
Means 
Hence, by year 2014 the population will be 77700.
All you have to do is multiply 23/4 by 4/3 which gets you 92/12
Simplify that and you get 23/3
Subtract to find the amount of tax paid then divide the amount of tax paid by the price of the item bought.
7.61 - 6.95 = 0.66 (amount of tax paid)
0.66/6.95 = 0.0949 x 100 = 9.49 %
Answer: 9.49 % (round off as needed)
