# Vector + absolute value - problems

1. Triangle Triangle KLM is given by plane coordinates of vertices: K[-12, -11] L[-15, -18] M[-13, -12]. Calculate its area and itsinterior angles. The rectangular crossroads comes passenger car and an ambulance, the ambulance left. Passenger car is at 43 km/h and ambulance 52 km/h. Calculate such a relative speed of the ambulance moves to the car. An airplane leaves an airport and flies due west 120 miles and then 150 miles in the direction S 44.1°W. How far is the plane from the airport (round to the nearest mile)?
4. Vector Calculate length of the vector v⃗ = (9.75, 6.75, -6.5, -3.75, 2).
5. Unit vector 2D Determine coordinates of unit vector to vector AB if A[-6; 8], B[-18; 10].
6. Vectors Vector a has coordinates (8; 10) and vector b has coordinates (0; 17). If the vector c = b - a, what is the magnitude of the vector c?
7. 3d vector component The vector u = (3.9, u3) and the length of the vector u is 12. What is is u3?
8. Rectangle 39 Find the perimeter and area of the rectangular with vertices (-1, 4), (0,4), (0, -1), and (-4, 4)
