Answer:
centre = (-5, -4)
radius = 7.42
Step-by-step explanation:
The general form for center-radius is
(x - h)² + (y - k)²= r²
Center = (h, k)
Radius = r
Rearrange the equation.
(x² + 10x) + (y² + 8y) - 14 = 0
Add 14 on both sides.
(x² + 10x) + (y² + 8y) = 14
(10/2)² = 25
(8/2)² = 16
Add 25 and 16 to both sides.
(x² + 10x + 25) + (y² + 8y + 16) = 14 + 25 + 16
Factor left side of the equation.
(x+5)² + (x+4)² = 55
(55) = (7.416198)²
(x+5)² + (x+4)² = 7.42²
The radius is 7.42.
The centre is at (-5, -4).
The answer is 80.58. You multiply 5 and 67.92 and then you add that answer to 67.Hope that helps!

Answer:
36 minutes.
Step-by-step explanation:
Piggly takes 6 minutes and Wiggly takes 5 minutes. Therefore Wiggly is travelling one minute slower.
If we just think about the first lap to start, and break it up into minute sections (like in the diagram attached), we can think about each pigs placement on the diagram for each lap.
At the end of the first lap, Piggly will have reached the end of the 6th minute section and will be back at the start/finish. Wiggly will only be at the end of the 5th minute section.
For the second lap, Piggly will again end up back at the start/finish, but Wiggly, having started his lap one section behind (at the end of the 5th section) will now end up even further behind (at the end of the 4th section).
Go ahead and count it out. Every lap he only covers 5 section, so every lap he falls one section further behind.
After six laps he will finish back at the start, at the same time as Piggly (but Piggly will be a lap ahead of him. Our sections have 6 minutes in each, and 6 laps are completed.
6 x 6 = 36 minutes
