How many g of amino acids are in a 2,000mL total parenteral nutrition of 4.25% travesol (amino acids and 20%dextrose?

kirill115 [55]

Answer:

The mass of amino acid present is 85 g

Step-by-step explanation:

From the question we are told that

The volume of the total parenteral nutrition is $V = 2000 mL$

Generally the volume of the amino acid present is

$V_a = 0.0425 * 2000$

$V_a = 85 mL$

Generally

$mass \ \ \alpha \ \ volume$

So the mass of amino acid present is 85g

Dentify all of the following solutions of square root of x plus 10 end root minus 4 equals x

Mrac [35]

Answer:

x = -1.

Step-by-step explanation:

√(x + 10) - 4 = x

√(x + 10) = x + 4

Squaring both sides:

x + 10 = x^2 + 8x + 16

x^2 + 8x - x + 6 = 0

x^2 + 7x + 6 = 0

(x + 6)(x + 1) = 0

x = -6, -1.

Check for any extraneous roots:

√(x + 10) - 4 = x

Try x = -6:

√(-6 + 10) - 4 = 2 - 4 = -2.

but we found x = -6 , so -6 is not a root.

Try x = -1:

√(-1 + 10) - 4 = 3 - 4 = -1. So x = -1 is a root.
