Answer: 14 weeks 5 days
Step-by-step explanation:
From the question, we are informed that Amir has 103 days to finish a project and that he works 7 days a week on the project.
The number of weeks and days that he has to finish the project will be:
= 103/7
= 14 5/7
= 14 weeks 5 days
Integral of 2sin(2x) is -cos(2x)
from 0 to pi/2 (sub pi/2 minus sub 0 for x) and then solve
= -cos(2*pi/2)-(-cos0)
= -cos pi + cos 0
= 1 + 1
= 2
