Write and solve an equation of ratios:

15 min              3 racks
----------      =     -------------
      x                  36 racks

Solving this for x:  3x = (15)(36)  =>  x = 180 minutes.

convert this into hours:     180 min        1 hr
                                         ------------ * -------------- = 3 hrs (answer)

The position of an atom moving inside a cathode ray tube is given by the function f(t) = t^3− 4t^2 + 3t where t is in seconds an
murzikaleks [220]

Answer:

A

Step-by-step explanation:

The position of an atom moving inside a cathode ray tube is given by the function:

f(t)=t^3-4t^2+3t

Where f(t) is in meters and <em>t</em> is in seconds.

And we want to determine its instantaneous velocity at <em>t</em> = 2.5 seconds.

The velocity function is the derivative of the position function. Thus, find the derivative of the function:

<em />f'(t)=3t^2-8t+3<em />

<em />

Then the instantaneous velocity at <em>t</em> = 2.5 will be:

f'(2.5)=3(2.5)^2-8(2.5)+3=1.75\text{ m/sec}

Our answer is A.
