We are given the following:
AB = 4800 miles
AO = 4000 miles
There is also a rule that states that a line tangent to a circle, will be perpendicular to the radius of the circle at the point of tangency. Therefore, triangle BAO is a right triangle.
We use Pythagorean theorem to solve for the hypotenuse BO.
BO = √(AO²+AB²) = √(4000²+4800²) = 6248 miles
But the problem asks for the length of BC. Since we know that OC is a radius of the circle, then:
BC = 6248 - 4000 = 2,248 miles.
The answer is C.

Answer:
The smaller number is -9.
Step-by-step explanation:
Let <em>x</em> and <em>y</em> be the two unknown numbers.
Their sum is -5. Hence:
Their difference is 13. Hence:
This yields a system of equations. We can solve this using elimination. Adding the two equations together:
Simplify:
Divide both sides by two. Thus:
Using either equation (I'll use the first):
So, our two numbers are 4 and -9.
The smaller number is -9.
