Answer: 2 over 1
Step-by-step explanation: Division and cause i am in Honors Geometry high school
There would be 1 real zero and two complex zeros
Step 1.
Calculate measure of angle α:
![47^o-38^o=9^o](https://tex.z-dn.net/?f=47%5Eo-38%5Eo%3D9%5Eo)
Step 2.
Calculate what fraction of the angle 360° is the angle α:
![\dfrac{9^o}{360^o}=\dfrac{1}{40}](https://tex.z-dn.net/?f=%5Cdfrac%7B9%5Eo%7D%7B360%5Eo%7D%3D%5Cdfrac%7B1%7D%7B40%7D)
Step 3.
Calculate the circumference of the Earth (circle):
![C=2\pi r\to C=2\pi\cdot4000=8000\pi\ mi](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r%5Cto%20C%3D2%5Cpi%5Ccdot4000%3D8000%5Cpi%5C%20mi)
Step 4.
The length of arc is equal 1/40 of the circumference:
![\dfrac{1}{40}C=\dfrac{1}{40}\cdot8000\pi=200\pi\ mi](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B40%7DC%3D%5Cdfrac%7B1%7D%7B40%7D%5Ccdot8000%5Cpi%3D200%5Cpi%5C%20mi)
![\pi\approx3.14\to\dfrac{1}{40}C\approx200\cdot3.14=628\ mi](https://tex.z-dn.net/?f=%5Cpi%5Capprox3.14%5Cto%5Cdfrac%7B1%7D%7B40%7DC%5Capprox200%5Ccdot3.14%3D628%5C%20mi)
<h3>Answer: A) 628 miles</h3>
