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.

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.
The maximum length is
mm.
