16' Given vectors u = (-6,4) and v = (7,10), determine if the vectors are orthogonal. If they are (I point) not orthogonal, nd the angle between the two vectors. 0 The vectors are orthogonal. O The vectors are not orthogonal. The angle between the two vectors is 91.3". 0 The vectors are not orthogonal. The angle between the two vectors is 98.0". 0 The vectors are not orthogonal. The angle between the two vectors is 80.6". 17. Which statement matches the vector operation shown on the coordinate grid? (1 point) Ov+ w= u for v =6i + 5j, w = 2i -4j , and u = 8i + j Ov+ w= u for v =6i + 5j, w = 2i -4j , and u = 4i + 9j Ov tu = w for v = 6i + 5j, u = 8i + j, and w = 2i -4j Ovtu = w for v = 6i + 5j, u = 8i + j, and w = 14i + 6j 18. Two forces act on an object. The first force has a magnitude of 300 newtons and acts at an (1 point) angle of 30 as measured from the horizontal. The second force has a magnitude of 150 newtons and acts at an angle of 135 as measured from the horizontal. Determine the vector v that represents the resultant force. Ov= (150
