For a certain mammal, researchers have determined that the mesiodistal crown length of deciduous mandibular first molars is related to the post conception age of the tooth as L(t) = − .015t² + 1.38t – 7.1, where L(t) is the crown length (in millimeters) of the molar t weeks after conception. Find the maximum length in mesiodistal crown of mandibular first molars during weeks 30 through 60.
