Como parte de un experimento de la clase
de Ciencias, Janina determinaba cuánto
soluto podía disolver en una solución al
aume. itar la temperatura. Al principio,
comenzó a disolver 50 g de soluto 2
temperatura ambiente en un recipiente
con 100 ml de agua, pero notó finalmente
que el soluto se acumulaba en el fondo del
vaso. Procedió a calentar la solución, lo
que le permitió disolver solo 10 g
adicionales de soluto.
¿Cuál solución obtuvo Janina al final del
experimento?
A sobresaturada
B insaturada
Csaturada
D diluida​

answer

a the answer hopes this

step-by-step explanation:

answer: i think it is (1,-2)

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
