Given the component form of vector v = {52,12}, which answer below could be the initial and terminal points for vector v? O A. initial (52,12) ; terminal (0, 0) O B. initial (14,5); terminal (66,?) O C. initial (520) ; terminal (0,12) 0 D. initial (12,16);terminal (64,-4) A cruise ship is traveling south going approximately 22 mph when it hits the Gulf Stream flowing east at 4 mph. Which expression would find the resultant velocity? O A. V223 +43 O B. /223 -42 O C. 222 -42 O D. 4(22)Given u = (1,3) and v = (2,6), find v + 2u. O A. (5, 15) O B. (4, 12) O C. (3, 9) O D. (6, 18)ls vector v with an initial point of (5, 22) and a terminal point of (20, 60) equal to vector u with an initial point of (50,120) and a terminal point of (75,158)? 0 A. No, the two vectors have different initial points but the same length. 0 B. No, the two vectors have the same magnitude but different slopes. O C. Yes, the two vectors have the same length and slope. O D. Yes, the two vectors have the same magnitude and direction. Determine if u = 2i + j and v = i + 2] are orthogonal, parallel, or neither. 0 O A. B. Vectors u and v are orthogonal because the clot product is equal to zero. Vectors u and v are parallel because the angle between the two vectors is equal to 0. . Vectors u and v are parallel because the angle between the two vectors is equal to 180. . Vectors u and v are neither because the angle between the two vectors is not equal to 0. 90, or 180.
