A merry-go-round initially at rest at an amusement park begins to rotate at time t=0 . The angle through which it rotates is described by θ(t)=(π/k)*(t+ke^(−t/k)) , where k is a positive constant, t is in seconds, and θ is in radians. The angular velocity of the merry-go-round at t=T is Zero

(5/2)kπ

(π/k)*(1−e^(−Tk))

i really hope this answer you out! it makes my day people like you and giving back to the community that has me through school! if you could do me a favor, if this you and this is the very best answer and you understand that all of my answers are legit and top notch. mark as brainliest! and have a awesome day!

less than one you can't create energy

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
