2cos^2 x = 1 + cos 2x
cos^2 x = 1/2(1 + cos 2x)
f(x) = 6cos^2 x - 4 sin 2x = 6(1/2(1 + cos 2x) - 4 sin 2x = 3 + 3cos 2x - 4sin 2x
Answer:
1.5 hours
Step-by-step explanation:
All you do is divide the speed by the distance 12/8=1.5 simple as that
Would be amazing if you marked me brainliest :)
36/2=18
18 would be your answer the radius is half of the diameter
They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
