Answer:10-i
Step-by-step explanation:
(5-9i)+(5+8i)
remove brackets
5-9i+5+8i
Collect like terms
5+5-9i+8i
10-i
Step-by-step explanation:
Since the focus lies on the x axis, and the diretcrtirx is a vertical line, we have a sideways parabola so we have the equation
where h,k is the vertex and
p is the distance from the vertex to the focus or the distance fromcthe vertex to the directrix.
Since the focus is 1.5, and the directrix is -1.5 the vertex is (0,0) so we have
We know p is 1.5 so we have
Answer:
EF=FC =22 ( diagonals bisect each other )
then EC=2 EF =2 x 22 =44
the opposite is squared so,
square root of 4 is 2 and 2 squared is 4
