Answer:

Given an angle ABC with B as your center you should put the compass with center in B and make an arc with a length that is more than the double of the angle. There you have the intersections between the arc and the segments BA and BC lets say the intersections is D and E, you should open the compass from D to E and make an arc starting D which intersects the previous arc-lets say that intersection is F. Now you should draw a segment using the straight hedge which starts in B and passes through F and ends in a new point let's call that one G with a length similar to AB and BC. So now you have the angle ABG with the center as B which is adjacent and congruent to ABC.

<span>Use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.

</span>Mark an arc through the sides of the angle. Let the arc intersect the rays at A and B. Continue the arc on past B for a distance. 

<span>Set the compass at B, and to the width of AB. </span>

<span>Still with the compass at B, mark an arc to intersect the first arc at C. </span>

<span>Now you have AB = BC. </span>

<span>Since the radius OA=OB=OC, angles AOB and BOC are congruent.</span>

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

Find the volume of the solid bounded by the sphere x^2+y^2+z^2=2z
liraira [26]
x^2+y^2+z^2=2z\implies x^2+y^2+z^2-2z+1=1\implies x^2+y^2+(z-1)^2=1

is a sphere centered at (0, 0, 1) with radius 1. We only need to know the radius; the volume is

V=\dfrac43\pi r^3

where r=1, so the volume would be \dfrac{4\pi}3.

If f(x) = <img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%20%2B3" id="TexFormula1" title="\sqrt{x} +3" alt="\sqrt{x} +3" align=
Delvig [45]

Answer:

f^{-1}(x) = x^{2}-6x+9 is the answer.

Step-by-step explanation:

If the function is f(x) = √x + 3

We will write the function as an equation

y = √x + 3

√x = y - 3

x = (y -3)²

x = y² -6y +9

Now we will convert the equation into a function

f^{-1}(x) = x^{2}-6x+9

Therefore the inverse function f(x) = x²-6x+9
