One-dimensional objects Find the mass and center of mass of the thin rods with the following density function.
ρ(x) = 1 + x3, for 0 ≤ x ≤ 1
An article describes a model for the movement of a particle. Assume that a particle moves within the region A bounded by the x-axis, the line x = 1, and the line y = x. Let(X, Y ) denote the position of the particle at a given time. The joint density of X and Y is given by the function below. Find P(0.5 < X < 1, 0 < Y < 0.5)

- Average value Compute the average value of the following functions over the region R. ƒ(x, y) = e-y; R = {(x, y): 0 ≤ x ≤ 6, 0 ≤ y ≤ ln 2}arrow_forwardA shape of a university campus is a square with side length of 10 miles. If you imagine the university on the x-y plane, in the first quadrant with two sides of the square on the positive axes, then the student union is at the origin (at a corner of the square). At noon on a certain day an announcement was made that all students had to walk to the student union. At that time the density function of the students spread over campus was given by: f(x, y) = (3/20000)*(x^2 + y^2 ) 0 < x < 10, 0 < y < 10, 0 otherwise. If students are only allowed to walk parallel to the axes what is the expected value of the distance walked to the student union by a randomly chosen student on campus? (Assume that students walk in a way that monotonically decreases their distance to the student union. That is, they don’t walk ” backward”.)arrow_forwardIntegrating over general regions: Find the average value of f over region D. f(x, y) = 5xy, D is the triangle with vertices (0, 0), (1, 0), and (1, 3).arrow_forward
