Answer:
$ 5.98
Step-by-step explanation:
20/100 × 22.42/1 = $ 4.48
$ 22.42 - $ 4.48 = $ 17.94
If they split that bill in two each would pay $ 5.98
I hope this helps.

![\Delta s \approx 334.545\,m](https://tex.z-dn.net/?f=%5CDelta%20s%20%5Capprox%20334.545%5C%2Cm)
Step-by-step explanation:
Let assume that Earth is a sphere, the following trigonometric diagram is constructed and presented below. The central angle is given by this inverse trigonometric equation:
![\theta = 2\cdot \cos^{-1} \left(\frac{r}{r+h} \right)](https://tex.z-dn.net/?f=%5Ctheta%20%3D%202%5Ccdot%20%5Ccos%5E%7B-1%7D%20%5Cleft%28%5Cfrac%7Br%7D%7Br%2Bh%7D%20%5Cright%29)
![\theta = 2\cdot \cos^{-1}\left(\frac{4000\,mi}{4000\,mi+3.5\,mi} \right)](https://tex.z-dn.net/?f=%5Ctheta%20%3D%202%5Ccdot%20%5Ccos%5E%7B-1%7D%5Cleft%28%5Cfrac%7B4000%5C%2Cmi%7D%7B4000%5C%2Cmi%2B3.5%5C%2Cmi%7D%20%5Cright%29)
![\theta = 4.792^{\circ}](https://tex.z-dn.net/?f=%5Ctheta%20%3D%204.792%5E%7B%5Ccirc%7D)
The distance of the portion of Earth that can be seen is:
![\Delta s = \frac{4.792^{\circ}}{360^{\circ}}\cdot (2\pi)\cdot (4000\,mi)](https://tex.z-dn.net/?f=%5CDelta%20s%20%3D%20%5Cfrac%7B4.792%5E%7B%5Ccirc%7D%7D%7B360%5E%7B%5Ccirc%7D%7D%5Ccdot%20%282%5Cpi%29%5Ccdot%20%284000%5C%2Cmi%29)
![\Delta s \approx 334.545\,m](https://tex.z-dn.net/?f=%5CDelta%20s%20%5Capprox%20334.545%5C%2Cm)
Answer:
B ($9.78)
Step-by-step explanation:
The key features of
polynomials are the vertex, axis of symmetry, x and y intercepts.
<span>1.
</span>The degree will help you find the end behavior.
<span>2. </span>The vertex shows you where it changes concavity.
<span>3. </span>X and y intercepts give you a couple of points
of reference.
<span>4. </span>Axis of symmetry is only applicable to even
degree polynomials.
