Step-by-step explanation:
2sin(x)cos(x) - sin(x) + 2cos(x)-1= 0
<=> sinx( 2cosx -1) + ( 2cosx -1) =0
<=> (sinx +1) + ( 2cosx-1)=0
<=> sinx=-1 or cosx= 1/2
+) sinx=1 => x= pi/2 + k×2pi
+)cosx=1/2 => x= pi/3+ k×2pi or x=-pi/3 + k×2pi
x€ [0,2pi] => x= pi/2, pi/3.
Answer: 5 1/2 hours
Step-by-step explanation:
1 hour = 12 miles
2 hours = 24 miles
3 hours =36 miles
4 hours = 48 miles
5 hours = 60 miles
6 hours = 72 miles
66- 60 = 6. 6 is half of 12.
In conclusion, it will take Tavyon 5 1/2 (or 5.5) hours to bike 66 miles.
Hope this helps!
