Answer:

Step-by-step explanation:

Slope of KL = (1-0)/(-3-0) = -⅓

Slope of JL = (3-0)/(1-0) = 3

The product of the slopes is -1, so L is a right angle. The orthocenter of a right triangle lies ON the triangle at the vertex of the 90° angle. Coordinates of orthocenter: (0,0)

:::::

DE is horizontal, so its altitude to F is the vertical line x=1. The altitude does not intersect segment DE, so the triangle is obtuse. The orthocenter of an obtuse triangle lies OUTSIDE of the triangle.

Slope of DF = (-2-2)/(-3-1) = 1

Altitude to E(-2,-2):

y+2 = -1(x+2)

y = -x-4

Orthocenter is Intersection of altitudes: =(1,-5).

You have a function y= \dfrac{3}{2} \left(1+\sin  \left(\dfrac{2t+1}{2}\cdot \pi\right) \right).
Since the range of the function y=\sin x is [-1,1] you have that

-1\le \sin \left(\dfrac{2t+1}{2}\cdot \pi\right)\le 1 \\ 0\le 1+\sin \left(\dfrac{2t+1}{2}\cdot \pi\right) \le 2 \\ 0\le \dfrac{3}{2} \left(1+\sin \left(\dfrac{2t+1}{2}\cdot \pi\right) \right)\le 3.
Answer: The range of given function is [0,3] and the correct choice is C.

Phantasy [73]
Okay so we are going to use Cos for this equation since this is Adjacent/hypotenuse.

I am going to attach a picture for the steps.
