Which point is on the line y=-2+3? (-2,-1) (3,3) (3,-3) (-3,-9)

Given that ot =5, xt=12, and ox= 13 is xy tangent to circle o at t? explain.

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 =
