Answer:
15.7 inches
Step-by-step explanation:
A clock is a circle . It tells us that the radius of the circle is 2.5 inches, and it is asking for the circumference. Therefore, we can use the equations for a circle to solve for the circumference.

Answer:
2√5
Step-by-step explanation:
The formula for the distance between a point (x, y) and a line in general form, ax +by +c = 0 is ...

The general form of your equation for the line is ...
2x +y -6 = 0
so the distance to point (x, y) = (4, 8) is ...

The distance between the point and line is 2√5.
For this case we must indicate the cosine of A, of the figure shown. By definition:

Substituting the values we have:

So, we have to:
