Describe fully the locus of the points representing z if (z+2i)/(z-2i) is purely imaginary

➷ The locus would be a circle with the radius 2

you can write it as a^2 + b^2 = 4^2

(the results value represents the locus of points for z)

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

The radius of the circle is 4 so a²+b²=4²

Step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
