Un cubo de plomo que tiene un volumen de 2m3 está a 40ºC y su volumen aumenta a 2.0012 cm3.¿cual será su temperatura final ?

59/96 is the ratio hope this not 100% sure though : /

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0 

15 cm is the answer to your question
