8. Which is an equation of a circle with center (-10, 6) and radius 8?
O (x + 10)2 + (y - 6)2 = 64
O (X + 10)2 + (y - 6)2 = 8
O
(x - 10)2 + (y + 6)2 = 8
(x - 5)2 + (y + 10)2 = 64

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
