Based on the information given, the computation shows that the distance between them is 2.47 miles.
<h3>
Solving the distance.</h3>
Since one has bearing 41°45', this will be: = 41° + (45/60) = 41° + 0.75 = 41.75°.
The other has bearing 59°13'. This will be:
= 59° + (13/60) = 59° + 0.22 = 59.22°.
The difference of the angles will be:
= 59.22° - 41.75°
= 17.47°
Let the distance between them be represented by c. Therefore, we'll use cosine law to solve the question. This will be:
c² = a² + b² - 2ab cos 17.47°
c² = 20² + 20² - (2 × 20 × 20 × 0.19)
c² = 6.07459
c = 2.47

Answer:
![b=-12](https://tex.z-dn.net/?f=b%3D-12)
Step-by-step explanation:
we have
![f(x)=x^{2}+bx+10](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E%7B2%7D%2Bbx%2B10)
we know that
The equation of a vertical parabola into vertex form is equal to
![y=a(x-h)^{2} +k](https://tex.z-dn.net/?f=y%3Da%28x-h%29%5E%7B2%7D%20%2Bk)
where
(h,k) is the vertex of the parabola
and the axis of symmetry is equal to ![x=h](https://tex.z-dn.net/?f=x%3Dh)
In this problem we have the axis of symmetry ![x=6](https://tex.z-dn.net/?f=x%3D6)
so
the x-coordinate of the vertex is equal to
therefore
For
-----> one unit to the right of the vertex
Find the value of ![f(7)](https://tex.z-dn.net/?f=f%287%29)
![f(7)=7^{2}+b(7)+10](https://tex.z-dn.net/?f=f%287%29%3D7%5E%7B2%7D%2Bb%287%29%2B10)
![f(7)=59+7b](https://tex.z-dn.net/?f=f%287%29%3D59%2B7b)
For
-----> one unit to the left of the vertex
Find the value of ![f(5)](https://tex.z-dn.net/?f=f%285%29)
![f(5)=5^{2}+b(5)+10](https://tex.z-dn.net/?f=f%285%29%3D5%5E%7B2%7D%2Bb%285%29%2B10)
![f(5)=35+5b](https://tex.z-dn.net/?f=f%285%29%3D35%2B5b)
Remember that
------> the x-coordinates are at the same distance from the axis of symmetry
so
------> solve for b
![7b-5b=35-59](https://tex.z-dn.net/?f=7b-5b%3D35-59)
![2b=-24](https://tex.z-dn.net/?f=2b%3D-24)
![b=-12](https://tex.z-dn.net/?f=b%3D-12)
The answer is B because they never pass through each other therefore it has infinite possibilities
