Incorrect. In vertex form $\displaystyle{y}={a}{{\left({x}-{h}\right)}}^{{2}}+{k}\usepackage{cmbright}\Huge\$ , the vertex of the parabola is given by $\displaystyle{\left({h},{k}\right)}\usepackage{cmbright}\Huge\$ . What is the vertex of the parabola $\displaystyle{h}=-{16}{{\left({t}-{5}\right)}}^{{2}}+{505}\usepackage{cmbright}\Huge\$ ? At the vertex, how far will the rocket have traveled, and how long will it have taken to get there?
