= 3 - 3cos x - 2(1- cos^2 x)
= 2cos^2 x - 3cos x + 1
=(cos x -1)(cosx - 1/2)
now cos x = 1 or cos x= 1/2
draw a graph we get = + ve values
hence .. 0 ,180,360 and 60,240, degrees in range x<2pi
Answer:
(-13, -12)
Step-by-step explanation:
The midpoint (x,y) between two points (
) and (
) on the coordinate plane is given by:
Hence given that house A is at (3, 6) and house B is at (-5, -3). Since house B is placed at the middle of house A and house B, let the coordinates of house C be (). Hence:
Therefore house C is at (-13, -12)
