Hi Friend,
Solution is as follows!
Pupils in ROSE SCHOOL = 2185
GIVEN THAT,
there are 307 people more in lily school
HENCE,
people in LILY school will be = 2180 + 307 =<span>2487.
</span>
ROUNDING OFF TO NEAREST 10 we get
<span>2490.
</span>____________________________________________________________
(ii)TOTAL NUMBER OF PUPIL IN BOTH ROSE AND LILY SCHOOL=
2185+2487=<u><em>4672</em></u>
ROUNDING OFF TO nearest 100 we get
<u>2500
</u>
HOPE THIS HELPS!!!
<span>use De Moivre's Theorem:
⁵√[243(cos 260° + i sin 260°)] = [243(cos 260° + i sin 260°)]^(1/5)
= 243^(1/5) (cos (260 / 5)° + i sin (260 / 5)°)
= 3 (cos 52° + i sin 52°)
z1 = 3 (cos 52° + i sin 52°) ←← so that's the first root
there are 5 roots so the angle between each root is 360/5 = 72°
then the other four roots are:
z2 = 3 (cos (52 + 72)° + i sin (52+ 72)°) = 3 (cos 124° + i sin 124°)
z3 = 3 (cos (124 + 72)° + i sin (124 + 72)°) = 3 (cos 196° + i sin 196°)
z4 = 3 (cos (196 + 72)² + i sin (196 + 72)°) = 3 (cos 268° + i sin 268°)
z5 = 3 (cos (268 + 72)° + i sin (268 + 72)°) = 3 (cos 340° + i sin 340°) </span>
