Determine two pairs of polar coordinates for (3,-3) when gº a. (3/2,459), (-34/2, 225° )
с. (34/2, 1359), (-34/2, 315° )
ь. (з 2, 315°). (-3/2, 1359)
a. (3/2, 225°), (-3/2, 45°)

Me solve this problem, and someone clearly explain to me how to solve it.1.) use the value of the discriminant to determine if the given trinomials has 2 real solutions, 1 real solution, or no real solutions.a.  x2  − 4x  − 7 = 0b. 4r2  + 11r  − 3 = 0c. 3m2  + 7 = 0d.  t2  + 2t  + 1 = 0

Express the following as a function of a single angle. cos(60) cos(-20) - sin(60) sin(-20)

Which system of linear inequalities is represented by the graph?
