Answer:
D
Step-by-step explanation:
You are given two complex numbers -i and 2+i.
For the complex number z=x+iy, the ordered pair (x,y) represents this complex number on the coordinate plane.
So, the numbers:
is represented by the ordered pair (0,-1)
is represented by the ordered pair (2,1).
Plot these two points on the coordinate plane and coonect them with a straight line. You'll get the last option of graph.
Dilation alters the length of the sides of a triangle but the angles remain the same
So cos x will still be 8/17
its 1200 i think i work it out but i could have done it wrong
Answer:
54 because I don't know I can't explain
