This is the way we are going to solve it.
1h = 60m ----------Steps
1. 7/8w=(1+1/6)h
2. 7/8w=(6/6+1/6)h
3. 7/8w=7/6*60m
4. 7/8w=(7*6*10*m)/6
5. 7/8w=70m
6. m=(7/8w)/70
<span>7. m=1/80w

Happy studying ^-^
Answer:
option 3
Step-by-step explanation:
Answer:
17.32 + 10i
Step-by-step explanation:
The product of the complex numbers;
z, = 5( cos 20° + i sin 20°)
za = 4( cos 10° + i sin 10°)
5( cos 20° + i sin 20°) × 4( cos 10° + i sin 10°)
= 20(cos20(cos10) + i sin20(cos10) + i sin10(cos20) + isin20(i sin10))
= 20(cos20(cos10) + i sin20(cos10) + i sin10(cos20) + sin20(sin10)i^2 )
And i^2 = -1
= 20(cos20(cos10) + i sin20(cos10) + i sin10(cos20) - sin20(sin10) )
= 20(cos20(cos10) - sin20(sin10) + i(sin20(cos10) + sin10(cos20)))
= 20(0.866 + i(0.5))
= 17.32 + 10i
The sum of -4 and 3 complain more because its negative
I think it's b okay Im sure
