9 = .18 * w
9/.18 = 50 ~ 900/18 = 50
Answer:
The answer is "
"
Step-by-step explanation:
When the value of
has the following properties:


Calculating the value of
:
![= 13 \times [ \cos(1.75 \pi ) + i \sin(1.75 \pi) ] \\\\= 13 \times[\cos(1.75 \pi - 2\pi ) + \ i \sin(1.75 \pi - 2\pi )]\\ \\= 13 \times [\cos(-0.25 \pi ) +\ i \sin(-0.25 \pi) ]\\\\= 13 \times [0.707106781 - 0.707106781]\\\\ =9.19 - 9.19\ i \\\\](https://tex.z-dn.net/?f=%3D%2013%20%5Ctimes%20%5B%20%5Ccos%281.75%20%5Cpi%20%29%20%2B%20i%20%5Csin%281.75%20%5Cpi%29%20%5D%20%5C%5C%5C%5C%3D%20%2013%20%5Ctimes%5B%5Ccos%281.75%20%5Cpi%20-%202%5Cpi%20%29%20%2B%20%5C%20i%20%5Csin%281.75%20%5Cpi%20-%202%5Cpi%20%29%5D%5C%5C%20%5C%5C%3D%2013%20%5Ctimes%20%5B%5Ccos%28-0.25%20%5Cpi%20%29%20%2B%5C%20%20i%20%5Csin%28-0.25%20%5Cpi%29%20%5D%5C%5C%5C%5C%3D%2013%20%5Ctimes%20%5B0.707106781%20-%200.707106781%5D%5C%5C%5C%5C%20%3D9.19%20-%209.19%5C%20i%20%5C%5C%5C%5C)
1 hour = 60 minutes
Tuesday: 60 divided by 4 = 15. Karen did it 3/4 of a hour so we multiply 15 by 4 which is 45. 45 equals 45 minutes. On Tuesday, Karen finished her chores in 45 minutes
Wednesday: first we divide 60 by 12 which is 5. 5 would equal 5 minutes. now we multiply 5 by 5 which is 25. Karen finished her chores in 25 minutes.
Answer: Karen finished her chores 20 minutes faster on Wednesday than Tuesday.
Hope this helps!
