Its height (above sea level) as time passes can be modeled by the quadratic function f, where f(t)=−4.9t^2+166.6t+130 Here t represents the number of seconds since the object’s release, and f(t) represents the object’s height (above sea level) in meters. 1) After this, this object reached its maximum height. 2) This object flew before it landed in the ocean. 3) This object was above sea level 24s after its release. 4) This object was 1526.5 m above sea level twice: once after its release, and again later after its release.arrow_forward
