The boundary of a lamina consists of the semicircles y = 4 − x^2 and y = 16 − x^2 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.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

i hope this is what you were looking for.

see attached graph

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

a ≈ 172.05

step-by-step explanation:
