Answer:
The answer is 12
Step-by-step explanation:
1/5 x 60 is 12
There is a 60 because There's 60 minutes in a hour.:)Have a good day❤
x = 0, π/3, π/2, 2π/3, π, 4π/3, 3π/2, 5π/3
sin(2x) + sin(4x) = 0
Use double angle formula.
sin(2x) + 2 sin(2x) cos(2x) = 0
Factor.
sin(2x) (1 + 2 cos(2x)) = 0
Solve.
sin(2x) = 0, cos(2x) = -½
2x = 0, 2π/3, π, 4π/3, 2π, 8π/3, 3π, 10π/3
one way to do this is to convert each fraction to same denominator ( the LCD)
Well we can eliminate -3/5 because its negative so 4/7 is definitely > -3/5.
4/7 = 16/28 and 3/4 = 21/28
so 4/7 < 3/4
Therfore 4/7 does lie between the 2 fractions
