iI think that c because it is inside the integers are inside the rationals
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)
Answer: 10 miles
Step-by-step explanation:
Given that :
Company A:
Flat rate = $30
Charge per mile = $1
Company B:
Flat rate = $20
Charge per mile = $2
Let x = number of miles
Company A total :
30 + x
Company B total :
20 + 2x
Miles needed To get the same total :
30 + x = 20 + 2x
30 - 20 = 2x - x
10 = x
Hence, 10 miles will be moved
