Radius = 7

Step-by-step explanation:

Since BA is tangent to circle O, it creates a 90° angle with the radius

Therefore, you can use Pythagorean theorem to solve this problem

a² + b² = c²

Let's say a is the radius

b is 5

c is 8.6

a² + 5² = 8.6²

a² + 25 = 73.96

Subtract 25 from both sides

a² = 48.96

Root both sides

a ≈ 6.997142274

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
