The distance between two point:
L=sqrt[(1-(-2))^2+(0-3)^2]=sqrt(18)=3sqrt(2) - <span>magnitude
</span>About <span>direction. Angle is 45</span>°, both point are on the line y=-x+1
434 rounded to the nearest ten is 430.
Hope this helps
The equation for the area of a circle is:

. Insert 9 as your radius (r) into the equation and solve:
\pi 9^2 = 254.469
The mathematical expression of the given complex number above is -5 + 4i. The conjugate of this complex number is that which has an opposite operation. The given is an addition operation. That is -5 - 4i. Therefore, the answer is the third among the choices.
I think it would be (x+7)/7
