Rewrite the equation in standard form. Find the center and radius of the circle.x2 + y2 + 6y - 27 = 0
A. x2 + (y - 3)2 = 36
center (0, 3), r = 6
B. (x + 3)2 + y2 = 36
center (-3, 0), r = 6
C. x2 + (y + 3)2 = 36
center (0, -3), r = 6
D. x2 + (y + 3)2 = 36
center (0, 3), r = 6

Use a system of equations to solve problem.Suppose that the position of a particle moving along a straight line is given by 
where t is time in seconds and a, b, and c are real numbers. If s(0) = 0.5, s(1) = 0.95, and s(2) = 1.8, find a, b, and c. Then find s(5).
A. a = -0.2, b = 0.25, c = 0.5; s(5) = 6.75 B. a = 0.2, b = 0.25, c = 0.5; s(5) = 6.75 C. a = 0.2, b = -0.25, c = 0.5; s(5) = 6.75 D. a = 0.2, b = 0.25, c = -0.5; s(5) = 6.75
