Suppose that the Type I region defined by R = {(8,4)2 5 5 0,9(2) 545 f()} has (737) as its centroid. Let k >o be an arbitrary positive real number. Use the formulas for finding the centroid to show that if f(x) and g(*) are multiplied by k, then the resulting region, R' = {(2,4)| 5 5 , kg(z) S4 5 #f(x)}, will have a centroid that is given by (7,ky).
