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

vova2212 [387]
For this case we have the following expression:
 h (t) = -16t ^ 2 + 64t + 80
 For t = 0 we have:
 h (0) = -16 (0) ^ 2 + 64 (0) + 80
 h (0) = -0 + 0 + 80
 h (0) = 80 feet
 Therefore the number 80 represents the initial height of the rocket
 Answer:
 
the 80 in the expression represented:
 
the initial height of the rocket
