- Density and mass Suppose a thin rectangular plate, represented by aregion R in the xy-plane, has a density given by the function ρ(x, y);this function gives the area density in units such as grams per squarecentimeter (g/cm2). The mass of the plate is ∫∫R ρ(x, y) dA. AssumeR = {(x, y): 0 ≤ x ≤ π/2, 0 ≤ y ≤ π} and find the mass ofthe plates with the following density functions.a. ρ(x, y) = 1 + sin x b. ρ(x, y) = 1 + sin yc. ρ(x, y) = 1 + sin x sin yarrow_forwardFluid runs through a drainage pipe with a 10-cm radius and a length of 30m (3000 cm). The velocity of the fluid gradually decreases from the center of the pipe toward the edges as a result of friction with the walls of the pipe. For the data shown, v(x) is the velocity of the fluid (in. cm/sec) and x represents the distance (in. cm) from the center of the pipe toward the edge. x 0 1 2 3 4 5 6 7 8 9 v(x) 195.5 195.1 194.5 193.5 192.2 190.6 188.8 186.6 184.2 181.5 Use regression to find a quadratic function to model the data.
