Andrew is using three pieces of scrap wood to build a wall shelf in his bathroom. The shelf will be shaped like a triangle, and the pieces of scrap wood measure 12 inches, 15 inches and 9 inches long. Will the shelf be shaped like a right triangle? Why or why not? A. Yes; 9² + 15² = 12²
B. Yes; 9² + 12² = 15²
C. No; 9² + 12² ≠ 15²
D. No; 15² + 12² ≠ 9²

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
