 P: 122 Just some things I need to verify: When finding the x-bar of the function y=x3 using the equation: $\bar{x}$ = $\frac{∫\tilde{x}dm}{∫dm}$, Is my $\tilde{x}$ going to be the x distance(which will just be "x") times x3? Also, will x3 be in the denominator just before "dm"? The same process is done for the $\tilde{y}$, am I correct? If I am also given a density $\rho$, will that stay in front of each integrand or in front of ($\frac{∫\tilde{x}dm}{∫dm}$)? Is the same process is done for the $\tilde{y}$ or are there differences? Thanks!
