Answer:
To moisten and to protect the airway from stuff like unknown pathogens and infection
Explanation:
The Trachea also known as the windpipe has tons of 'little hairs' called cilia in the epithelium that protect the throat. When someone smokes or breathes in gases it is destroyed and exposes the trachea. But thats another story. :)
The graph of y = -2x + 3 is a straight line
Its slope is - 2
Its y-intercept is + 3
To draw the line you can use these two points (0,3) and (3/2 , 0)
This line does ont pass through the third quadrant. It comes downward from the second quadrant, touches the y-axis at y =3, continues on the rirst quadrant, touches the x-axis at x = 3/2, and contiues into the fourth quadrant.
Graph of its inverse
Exchange y and x in the given function and solve for the new y
x = - 2y + 3 => y = - x/2 + 3/2
It is also a straight line;
Its slope is -1/2
Its y-intercept is 3/2
It is also in the second, first and fourth quadrant
Use these two points to draw the line (0,3/2) and (3,0).
You do not need to know to draw this, but the inverse of a function is its reflection through the line y =x.
Carlos will have to consume about 63 gram of protein per day.
The dietary reference intake of protein is 0.8 gram of protein per kilogram body weight or 0.36 gram per pound. Carlos is 175 pounds in weight, so he is going to need 0.36 * 175 = 63. Thus, Carlos needs 63 grams of protein per day.<span />
