<span>If the walkers start at nine and want to join the cyclists at
noon, they will have been walking for 3 hours. At 5 km/h, they would have
walked for 15 km. The cyclists can travel 15 km at 12 km/h in 1.25 hours.
Therefore, the cyclists can start their journey at 10:45 am.</span>
three different forms: standard, intercept and vertex
Answer:
Center = (4, -5)
radius = 6
======================================================
Explanation:
The general template of any circle is
(x-h)^2 + (y-k)^2 = r^2
Rewrite the given equation into this form
(x-4)^2 + (y- (-5))^2 = 6^2
We can see that (h,k) = (4,-5) is the center and r = 6 is the radius.
