Answer:
c) (-5, -7)
Step-by-step explanation:
In a parallelogram, the midpoints of the diagonals are the same point. This means ...
(R+T)/2 = (S+U)/2
R +T -S = U
(-6 +4 -3, -3 -1 -3) = U = (-5, -7)
Answer:
2x+5
Step-by-step explanation:
I'm sorry, but I don't know how to explain this. I hope it helps though.
4 cos² x - 3 = 0
4 cos² x = 3
cos² x = 3/4
cos x = ±(√3)/2
Fixing the squared cosine doesn't discriminate among quadrants. There's one in every quadrant
cos x = ± cos(π/6)
Let's do plus first. In general, cos x = cos a has solutions x = ±a + 2πk integer k
cos x = cos(π/6)
x = ±π/6 + 2πk
Minus next.
cos x = -cos(π/6)
cos x = cos(π - π/6)
cos x = cos(5π/6)
x = ±5π/6 + 2πk
We'll write all our solutions as
x = { -5π/6, -π/6, π/6, 5π/6 } + 2πk integer k
