There are 4 parts to this :)

Thank you so much for helping!! PART ONE:

1. Vector C is 10 units down and Vector D is 5 units up. What is the measure of Vector C + Vector D? Be sure to show and explain your work. Q 5 units up O 5 units down 0 15 units down 0 15 units up 2, Vector B is 5 units up, Vector C is 10 units up and Vector D is 5 units down, What is the measure of Vector B + Vector C Vector D? Be sure to Show and explain your work, Q 15 units down O 5 units up 0 20 units up D 10 units down 3. Vector C is 4 units down and Vector D is 5 units up. What is the measure of Vector C - Vector D'? Be sure to show and explain your work. 4. Which of the following are expressed as vectors? O speed O height O Velocity O energy1. Jackson is training for his college cross country team. He runs west and then north. He then runs 6.3 km at an angle of 409. East of South back to his starting location. How far did he run West? Answer to the nearest hundredth. O 4.05 km O 10.35 km O 4.83 km O Cannot be determined2. A vector heads 45 m/s at 45 above the horizontal. What is the horizontal component of this vector? O 10.8 O Cannot be determined 31.82 O .023. Ms. Lobert kicks a ball off a building with a velocity of 14.2 m/s at an angle of 339. The wind blows it horizontally in the direction of the ball's motion. if the wind travels at 12.0 m/s, what is the overall initial velocity of the ball? Round to the nearest hundredth at each step.4.A cruise ship heads at a bearing of:- for 15 miles, then travels another 40 miles at a bearing of -. What is the bearing of the displacement from its initial position? 0 Cannot be determined 0 15.25 0 20.11" 0 30:. 5 A cruise ship heads at a bearing of:- for 15 miles, then travels another 40 miles at a bearing of - What is the mileage of the displacement from its initial pOSItion? 0 4393 miles 0 Cannot be determined 0 45.25 miles 0 1051 miles 1. Find |A+ B| (C- D) using the following vectors: A= B = C= D = O C None of the above O O 2. Find A+ B - C- _ using the following vectors: A = B = C= D = O O 3. Find | A + B) using the following vectors: A= C= D= O 5 ~2 O 7~2 O 4.Two vectors E and E with and - have an angle of between them. Determine to the nearest hundredth by drawing a parallelogram. Be sure to show and explain all work. 1. A chemist has one solution that is 40% acid and a second that is 50% acid. how many liters of each should be mixed to get 10 L of a solution that is 45% acid? O 2 W/ H liters of the 40% acid WIN liters of the 50% acid O 2 . liters of the 40% acid 3 liters of the 50% acid 5 liters of the 40% acid 5 liters of the 50% acid 1 liter of the 40% acid 7.5 liters of the 50% acid2. How many solutions does the following system have? y = 2x + 7 2y-4x = -10 O One Solution O Infinite Solutions O No solution Two Solutions3. Solve the following system: y = 2x + 7 xty =13 O (1, 9) O (3, 13) O (-2, 3) O (2, 11)4.
