Find the 3 × 3 matrix that produces the following composite 2d transformation, using homogeneous coördinates: shift points 2 units in the r-direction and -3 units in the y-direction, then rotate through 45°, then reflect across the origin. (hint: see section 1.9 for some possibly useful information.)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

a mantle plume is an upwelling of abnormally hot rock within the earth's mantle. as the heads of mantle plumes can partly melt when they reach shallow depths, they are thought to be the cause of volcanic centers known as hotspots and probably also to have caused flood basalts.
