<span>(x - h)² + (y - k)² = r²

is the equation of the circle with center (h, k) and radius r units.

Thus (x + 2)² + y² = 10 is the equation of a circle whose center is at the point (-2, 0) and having a radius of √10 units<u>

Answer:

1.8 miles

Step-by-step explanation:

For this case we can model the problem as a rectangle triangle.

We know:

Length of the sides of the triangle

We want to know:

Length of the hypotenuse

Using the Pythagorean theorem we have:

$d=\sqrt{3^{2} +3^{2} }\\d = \sqrt{2(3^2)} \\d = 3\sqrt{2} \\d = 4.2 miles$

Then, the distance that he would have saved if he travels directly is:

$3 + 3 - 4.2 = 1.8 miles$

Answer:

he would have saved:

1.8 miles
