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) = - .015t^2 + 1.42t - 7.4, where l(t) is the crown length (in millimetres) 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. (round to three decimal places as needed.)

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

part a: 1.08

part b: 27.59

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
