In a fluid dynamics experiment, the drag coefficient DDD of a specialized underwater drone is modeled as a function of its velocity vvv (in m/s) by the expression:
D(v)=32v2−14v+54v−1D(v) = \frac{32v^2 - 14v + 5}{4v - 1}D(v)=4v−132v2−14v+5
The expression can be written in the form:
D(v)=Av+B+C4v−1D(v) = Av + B + \frac{C}{4v - 1}D(v)=Av+B+4v−1C
where A,BA, BA,B, and CCC are constants. State the value of AAA.
