The half angle formula is:
sin x/2 = +/- √ (( 1-cos x ) / 2 )
5π/12 = 5π/6 : 2
sin 5π/12 = +/- √(( 1 - cos ( 5π/6)) / 2 )
cos 5π/6 = cos 150° = -√3/2
≈ 0.966 ( this is sin 5π/12 )
We have the following given
mileage = 70 miles per gallon
distance = 60 km
Required: amount of fuel in gallons
First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi
So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallons
Answer:
x=1 or 0
Step-by-step explanation:
because if X is 1 then 3*1 is 3 and 3+2 is five then it's bigger than -10 and smaller than 8
0*3 is 0 then 0 plus 2 is 2 which also works
Answer:
2 x 7 is 14 and you just add the two zero's?
