Answer:
1300
Step-by-step explanation:
thousand hundred tens one
1 2 8 3
We are rounding to the nearest hundred
Looking at the tens
8 is 5 or greater we round the hundreds up
1300
Since work = force * distance, the answer would 5*.5, which is 2.5 J

Answer:
48 pieces are cut.
Step-by-step explanation:
1/12 of an inch means that one inch would be 12 pieces. Since there are 4 pieces it would be 12x4= 48 pieces.
Sin2(x) +cos(x)=1
from the relation: (sin2(x) +cos2(x) =1 )
so , sin2(x)=1-cos2(x)
by subs. in the main eqn.
1-cos2(x) + cos(x) =1
by simplify the eqn.
cos(x) -cos2(x)=0
take cos(x) as a common factor
cos(x)* (1-cos(x))=0
then cos(x)=0 && cos(x)=1
cos(x)=0 if x= pi/2
& cos(x) = 1 if x = 0 , 2*pi
so the solution is x= {0,pi/2 , 2*pi}
