Answer:
x = 0 , π
Step-by-step explanation:
- Rewrite it by using the identity


- Add 4sin x to both the sides.


- Take sin x common from the expression in L.H.S.

Here , we can get two more equations to find x.
1) 
- Divide both the sides by sin x


- Substract 4 from both the sides.



2) 
- Divide both the sides by (sin x + 4)


over interval [0 , 2π).
Answer:
Dylan delivered 140 parcels on Wednesday.
Step-by-step explanation:
On Wednesday:
On Wednesday, he delivered x parcels.
Thursday:
10% more than Wednesday, so 100 + 10 = 110% of x = 1.1x
Friday:
50% pless than on Thursday, so 100 - 50 = 50% of 1.1x = 0.5*1.1*x.
THis is equals to 77. So



Dylan delivered 140 parcels on Wednesday.
No, they do not have a pattern nor do they flow to get her the difference between 6 and 11 is 5, whereas the difference between 11 and 17 is 6.
