Answer:

40.5g of salt is left after evaporating all the water.

Step-by-step explanation:

Here, 9% of 450g means that out of 450 gram of solution, 9% is the salt.

So, we need to calculate 9% of 450

i.e. 9% * 450 = 0.09 * 450 = 40.5g

Hence, 40.5 grams of salt is in 450 grams of solution.

i.e. 40.5g of salt is obtained after evaporating all the water from the solution.

Stells [14]

Answer:

D is the answer

64,000 exponential function  

Step-by-step explanation:

64,000 exponential function  

The number of bacteria in a colony doubles  every 210 minutes.

The population of bacteria = 8000

Determine how many times the population will double.

\frac{630}{210}

 = 3

Multiply the population by 2 a total of 3 times.

8000 × 2³ = 64,000

Raíz cuadrada de 864

Para resolver este problema debemos tomar en cuenta los datos que nos dan y la ecuación de una hipérbola. Comencemos con los datos:

The general equation of ellipse is given as, x2a2+y2b2=1 x 2 a 2 + y 2 b 2 = 1 , where, a is length of semi-major axis and b is length of semi-minor axis.

centro: (0,0)

focus : (0, -√28) , (0, √28)

eje conjugado = 2√3

por los focos podemos ver que la hipérbola se dirige hacia el eje y, por lo que debemos tomar la siguiente forma de la ecuación de la parábola:

de los focos podemos obtener que: √28

y del eje conjugado podemos saber que al dividir la longitud del eje conjugado dentro de 2 obtenemos b, así que:

b = √3

podemos utilizar la siguiente fórmula para obtener a:

si despejamos a en la ecuación obtenemos lo siguiente:

ahora podemos sustituir los valores:

a=5

así que media vez conozcamos a, podemos sustituir los datos en la ecuación de la hipérbola así que obtenemos lo siguiente:

si graficamos la hipérbola, queda como en el documento adjunto.
