Cos 180 = -1
sin 180 = 0

So you put in the answer that when you revert it into complex again, it would be -4.

The correct answer would be 4(cos 270 + i sin 270)

Label the parts of the equation 4x6=24
Alisiya [41]

The numbers are constants, and the multiplication symbol is an operator.

If this equation were 4x * 6 = 24, then 4 would be a coefficient and x would be a variable. 6 and 24 are still constants and the multiplication symbol is still an operator.

If you take pen off lessons apps 4:15 p.m. and it ends at 5:50 p.m. how long does he practiss
nekit [7.7K]
Hi there!

To solve this problem, we need to subtract 5:50 from 4:15 pm.

5:50 - 4:15
= 6:00 - 4:15 - 0:10
= 6:00 - 4:00 - 0:10 - 0:15
= 1 hr 35 min

So, your answer would be 1 hr 35 min. 

Hope this helps!
