Biologists have proposed a cubic polynomial to model the length L of Alaskan rockfish at age A: L = 0.0155A³ – 0.372A² + 3.95A + 1.21, dL where L is measured in inches and A in years. Calculate - - (Round your answer to three decimal places.) dA A= 18 dL in/yr dA A= 18 Interpret your answer. A 18-year old rock fish shrinks at a rate of 5.624 in/yr. A 18-year old rock fish grows at a rate of 65.893 in/yr. A 18-year old rock fish shrinks at a rate of 65.893 in/yr. A 18-year old rock fish grows at a rate of 60.269 in/yr. OA 18-year old rock fish grows at a rate of 5.624 in/yr.
