Let v = (7,8). Suppose w E R is perpendicular to v, and that ||w|| = 7. Find both possible vectors w. (Use symbolic notation and fractions where needed. Give your answer as comma separated list of the vector's components in the form (*.*).(*.*).) W = Calculate u, the normalization of the vector v = -4i + 11j + 3k. (Write your solution using the standard basis vectors i, j, and k. Use symbolic notation and fractions where needed.) u=
