Answer:
center (-5, 3)
radius 3
Step-by-step explanation:
Compare the given equation to the standard form equation of a circle:
(x -h)² +(y -k)² = r² . . . . . . circle with center (h, k) and radius r
This shows us that ...
-h = +5 ⇒ h = -5
-k = -3 ⇒ k = 3
r² = 9 ⇒ r = √9 = 3
Then the circle center is (h, k) = (-5, 3), and the radius is r = 3.

Answer: 
Step-by-step explanation:
Given
The position of a particle is 
Velocity is given by the derivative of position with respect to time
So, velocity is constant at any point in time.
At t=8, it is
