The boundary of a lamina consists of the semicircles y=sqrt(1 − x2) and y= sqrt(16 − x2) together with the portions of the x-axis that join them. find the center of mass of the lamina if the density at any point is inversely proportional to its distance from the origin.

do you mean add both of the equations together

because if you do the answer is 10x-5

step-by-step explanation:

7.3

step-by-step explanation:

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

a. true
