1.Polar coordinates of a point are given. Find the rectangular coordinates of the point. (-5, -180°)

A. (-5, 0)

B. (0, -5)

C. (0, 5)

D. (5, 0)

2.Plot the complex number. 2 + i

3.Use the dot product to determine whether the vectors are parallel, orthogonal, or neither. v =?^2 j, w = 4i A. orthogonal B. parallel C. neither

4.Solve the triangle. Round lengths to the nearest tenth and angle measures to the nearest degree. a = 6, c = 11, B = 109°

A. b = 14.1, A = 24°, C = 47°

B. b = 19.9, A = 22°, C = 49°

C. b = 17, A = 26°, C = 45°

D. no triangle

5.Polar coordinates of a point are given. Find the rectangular coordinates of the point (2.1,2pi/9)
A. (-1.6, -1.3)

B. (1.6, 1.3)

C. (1.3, 1.6)

D. (-1.3, -1.6)
