Answer:
1. at 1 hour, 3 miles is the distance.
2. at 0 hours, 0 miles is the distance.
3. at 3 hours, 9 miles is the distance.
Sin-1 (3/5) = 36.869
cos 3/5 = 0.999
Given that the radius r of a circle is written as a function of the area A with the following equation:
![r=\sqrt[]{\frac{A}{\pi}}](https://tex.z-dn.net/?f=r%3D%5Csqrt%5B%5D%7B%5Cfrac%7BA%7D%7B%5Cpi%7D%7D)
The domain of the above function is the area A of the circle.
This is because, in this context, the area is an independent and unique variable.
A is the input value.
The factors of 28 are 1 x 28, 2 x 14, and 4 x 7. None of which add up to 20.
