√-1 = i
=(√12 - √-3)(3 + √-4)
=(√12-3i)(3+4i)
=3√12 + 4i√12 - 9i -12i²
=3(2√3) + 4i(2√3) - 9i - 12(-1)
=6√3 + 8i√3 - 9i +12
=12 + 6√3 - 9i + 8i√3
=6(2 + √3) - (9 + 8√3)i

The speed, s, of the current in a certain whirlpool is modeled by s=300/d, where d is the distance from the center of the whirlp
JulijaS [17]
For this case we have the following equation:
 s = 300 / d
 Where,
 s: the speed of the current in a certain whirlpool
 d: the distance from the center of the whirlpool
 We have then that:
 If the distance from the center of the whirpool is large, the speed is small.
 If the distance from the center of the whirlpool is very small, the speed tends to infinity
 Answer:
 
Large distance, small speed.
 
Short distance, speed tends to infinity.
