The most important thing in this problem is understanding and then dividing the given units properly. The first thing that is given is that the CD makes 58 1/2 revolutions in 3/4 minutes. We have to first simplify the number of revolutions made by the CD. This will make the problem in hand very easy.
Number of revolutions made by the CD = 58 1/2
                                                               = 117/2
Then
The unit rate = (117/2)/(3/4)
                     = (117 * 4)/(2 * 3)
                     = (117 * 2)/3
                     = 39 * 2
                     78
So the unit rate is 78 revolutions per minute.

How can you tell if a function is quadratic?
Paha777 [63]
There are several ways, but the general format follows f(x) = ax2 + bx + c f(x) = ax² + bx + c, where A, B, and C are non-zero numbers. Another way of finding a quadratic equation is examining the graph of it, you'll notice a "U" shape called a parabola, which come in many shapes but they all retain a "U"-like curve.
