Its arithmetic because it adds 1o each time
A circle is a set of points in a plane equidistant
from a fixed point. It has a general formula of x² + y² = r². This is if the
center is at the origin. However, if the center at point h and k, the
equation becomes (x-h)² + (y-k)² = r².<span>
We write the given equation in the
form (x-h)² + (y-k)² = r² by completing the square.

<span>x</span>²<span> + y</span>²<span> + 10x – 6y + 18 = 0</span>
<span>
(x² + 10x + 25 )+ (y² - 6y + 9) = −18 + 25 + 9 = 16
(x + 5)² + (y + 3)² = (4)²
Therefore,
center = (-5, -5)
radius = 4</span>
Answer:
503 inches (rounded to the nearest whole number)
Step-by-step explanation:
First, we must calculate the wheel's circumference, or in other words, the distance around the wheel. We can do this by using the below equation:
when 
is the diameter
Because we know that the wheel's diameter is 16 inches, we can plug it into the equation:
Now, because we know that the wheel makes 10 revolutions, we calculate the distance it travelled by multiplying the circumference by 10.
inches when rounded to a whole number
Therefore, the wheel travelled approximately 503 inches.
I hope this helps!
