Answer:
Option A: Because this is a rectangle, I would show that each vertex is made up with lines that have opposite reciprocal slopes.
Step-by-step explanation:
A rectangle is a quadrilateral with four right angles.
Each right angle is made up of two perpendicular lines forming a vertex
And then proving this that all perpendicular lines have negative reciprocal slope.
It isn't always necessary to employ the idea of using a parallelogram first although it might be useful.
Answer:
Step-by-step explanation:
the average rate of change is m= -1/4
Answer: 2 - 2*sin³(θ) - √1 -sin²(θ)
Step-by-step explanation: In the expression
cos(theta)*sin2(theta) − cos(theta)
sin (2θ) = 2 sin(θ)*cos(θ) ⇒ cos(θ)*2sin(θ)cos(θ) - cos(θ)
2cos²(θ)sin(θ) - cos(θ) if we use cos²(θ) = 1-sin²(θ)
2 [ (1 - sin²(θ))*sin(θ)] - cos(θ)
2 - 2sin²(θ)sin(θ) - cos(θ) ⇒ 2-2sin³(θ)-cos(θ) ; cos(θ) = √1 -sin²(θ)
2 - 2*sin³(θ) - √1 -sin²(θ)
