- Vector Operations In Exercises 2932, find a uv, b 2(u+3v), c 2vu. u=(6,5,4,3),v=(2,53,43,1)arrow_forwardVector Operations In Exercises 19-24, let u=(1,2,3), v=(2,2,-1), and w=(4,0,-4). Find 2u+4vw.arrow_forwardError Analysis Describe the error in finding the component form of the vector u that has initial point 3,4 and terminal point 6,1. The components are u1=36=9and u2=41=5. So,u=9,5.arrow_forward
- Finding the Length of a Vector. In Exercises 1-4, find the length of the vector. v=(5,3,4)arrow_forwardTake this test to review the material in Chapters 4 and 5. After you are finished, check your work against the answers in the back of the book. a Explain what it means to say that a set of vectors is linearly independent. b Determine whether the set S is linearly dependent or independent. S={(1,0,1,0),(0,3,0,1),(1,1,2,2),(3,4,1,2)}arrow_forwardFinding the Difference of Two Vectors In Exercises 103 and 104, use the program in Exercise 102 to find the difference of the vectors shown in the figure.arrow_forward
- Determining a Relationship Between Two Vectors In Exercises 47-54, determine whether u and v are orthogonal, parallel, or neither. u=(2,18), v=(32,16).arrow_forwardExercises Finding a Unit Vector. In Exercises 912, find a unit vector a in the direction of u and b in the direction opposite that of u. Verify that each vector has length 1. u=(3,2,5)arrow_forwardTake this test to review the material in Chapters 4and Chapters 5. After you are finished, check your work against the answers in the back of the book. Write w=(7,2,4) as a linear combination of the vectors v1, v2 and v3 if possible. v1=(2,1,0), v2=(1,1,0), v3=(0,0,6)arrow_forward
- Vector Operations In Exercises 19-24, let u=(1,2,3), v=(2,2,-1), and w=(4,0,-4). Find u-v and v-u.arrow_forwardReview Exercises Solving a Vector Equation In Exercises 5-8, solve for x where u=(1,1,2), v=(0,2,3) and w=(0,1,1) 2xu+3v+w=0arrow_forwardFinding the Component Form of a Vector In Exercises 1 and 2, find the component form of the vector.arrow_forward
