Question 8 (1 point) Two vectors u? and v? are at 90° to each other oriented tail to tail. If both vectors have magnitude 1, then: u? + v? = 2 |u?| + |v?| = 2 |u? ? v?| = ?2 u? ? v? = 0 Question 9 (1 point) A plane sights an airport at [N20°E] and is travelling at a speed of 500 km/h. There is a wind from [N30°W] at a speed of 25 km/h. Determine the heading the airplane must travel in order not to miss the airport. [S18?W] [N45?E] [S14?W] [N18?E]

Step 1
Step 1: Calculate the magnitude of vector U + vector V: Given that both vectors have magnitude 1, the magnitude of U + V can be calculated as: |U + V| = √(1^2 + 1^2 + 2*1*1*cos(90°)) |U + V| = √(1 + 1) |U + V| = √2 Show more…

1) An airplane pilot sets a compass course due west and maintains an airspeed (velocity of the plane with respect to the air) of 240 km/h. After flying for V hours, he finds himself over a town 150 km west and 40 km south of his starting point. Find the velocity of the wind with respect to the ground. b) If the wind velocity were 120 km/h due south, in what direction should the pilot set his course in order to travel due west? Keep the same airspeed as above. (Hint: treat this as a vector addition problem)

9. If a vector is described as an airplane flying North at 400km/h, then the opposite vector can be described as: a) An airplane flying North at -400km/h b) An airplane flying South at 400km/h c) An airplane flying South at 800km/h d) Both b and c 10. For u • v, if the sign of u • v is negative, then the angle between the tail to tail vectors will be: a) 0° < Θ < 90° b) Θ = 90° c) 90° < Θ < 180° d) Sign does not indicate angle range 11. Evaluate the following limit: lim (x→3) (9-x²)/(3-x) a) Undefined b) 3 c) 6 d) 0 12. Determine the slope of the tangent to the curve y = 2sinx + sin²x when x = π/6. a) 5/4 b) 0 c) 3√3/2 d) (3+4√3)/4
