Solve the equation on the interval [0, 2π).

tan2x sin x = tan2x

a. 0, (pi)/2

b. (pi)/2 , 2π

c. (pi)/2 , π

d. 0, π

40 points which is the equation of a line perpendicular to the line with the equation: y = 1/4x + 2 a : y = -4x - 7 b : y = 4x + 2 c : y = 1/4x - 1/2 d : y = -1/4x + 3

On a piece of paper, graph y+2< _-2/3x+4. then determine which answer choice matches the graph you drew?
