Answer:
4). 47 - 29i
Step-by-step explanation:
(5+√-36)*(1-√-49)=5*1 -5√-49+1*√-36 -√-36√-49 = 5-5*7i +6i-6i*7i=
=5-35i+6i-42(-1)=5+42-41i= 47 - 29i
Answer:
Step-by-step explanation:
The scale factor of dilation of triangle ΔOPQ, S.F. = 3
The center of dilation = Point <em>Q</em>
Therefore;
The length of the segment, = 3 × The length of the segment,
Similarly;
The length of the segment, = 3 × The length of the segment,
By Pythagoras theorem, we have;
Therefore;
.
