This structure is called the epiglottis. This flexible leaf-shaped cartilage serves as a flap that covers the larynx to prevent food and liquids from entering the airway and the lungs. It is open when we breathe which allows air to enter into the larynx.
For plants, it's photosynthesis.
Answer:
- <u>The hours are the independent variable.</u>
- <u>The wages/wk earned are ( $11/hr )x( hrs worked )
. This is the dependent variable ( depends on hours worked )
.</u>
- <u>The domain is 0 to 30
</u>
- <u>The range is 0 to 330
</u>
Explanation:
<em>The hours are the independent variable and should be plotted on the x-axis
.</em>
<em>The wages/wk earned are ( $11/hr )x( hrs worked )
. This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis
</em>
<em>---------------
</em>
<em>Let +W+ = wages/wk earned
</em>
<em></em>
<em>Let +h+ = hours/wk worked
</em>
<em>The equation is:
</em>
<em>+W+=+11h+
</em>
<em>The domain is 0 to 30
</em>
<em>( no hrs worked to 30 hrs worked )
</em>
<em>The range is 0 to 330
</em>
<em>( no wages eared to +11%2A30+=+330+ earned )</em>
Horizontal lines, like the horizon. That's how I remember it, anyways. Or on a globe, latitude lines. My teacher always taught us "FAT-itude lines."
