Use spherical coordinates. (a) find the centroid of a solid homogeneous hemisphere of radius 2. (assume the upper hemisphere of a sphere centered at the origin. use the density function ρ(x, y, z) = k. ) (x, y, z) = 0,0, 3 4 (b) find the moment of inertia of the solid in part (a) about a diameter of its base.

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

is there a question here?
