bonjour
p (t) = t - 100 - ( t - 150) / 4
p ( 170) = 170 - 100 - ( 170 - 150 ) / 4
p ( 170) = 70 - ( 20 / 4 )
p ( 170) = 70 - 5 = 65
poids idéal = 65 kg
p ( 200 ) = 200 - 100 - ( 200 - 150 ) / 4
p ( 200 ) = 100 - ( 50 /4 )
p ( 200 ) = 100 - 12.5 = 87.5
poids idéal = 87.5 kg
3 ) graphique
4 ) t - 100 - (t - 150 ) / 4 = 74
t - 100 - ( t/4 - 150 /4) = 74
4 t /4 - 400 /4 - (t/4 - 150 /4 ) = 296/4
4 t - 400 - t + 150 = 296
3 t = 296 + 400 - 150
3 t = 546
t = 182
il mesure 1.82 m
