Problem:Using factoring, determine how long an object stays in the air if its height is defined by these parametric equations.x(t) = 4ty(t) = -16t2 + 1024
-16t2 + 1024 = 0
-16(t2 - ) = 0
-16(t - )(t + ) = 0
t - = 0 OR t + = 0
t = OR t =
Solution:This object will stay in the air for seconds.
x(t) = 4ty(t) = -16t2 + 1024
