Find the first partial derivatives of the function. (Sn = x1 + 2x2 + ... + nxn; i = 1, ..., n. Give your answer only in terms of Sn and i.) u = sin(x1 + 2x2 + ⋯ + nxn)

What does the relationship between the mean and median reveal about the shape of the data

Angle xyz is formed by segments xy and yz on the coordinate grid below: a coordinate plane is shown. angle xyz has endpoints at 3 comma negative 1 and 6 negative 2 and 3 comma negative 3 and measures 36.87 degrees. angle xyz is rotated 270 degrees counterclockwise about the origin to form angle x′y′z′. which statement shows the measure of angle x′y′z′?

Which linear inequality is represented by the graph?
