Question

can anyone help me??
water is spraying from a nozzle in a fountain, forming a parabolic path as it travels through the air. the nozzle is 10 cm above the surface of the water. the water achieves a maximum height of 100 cm. above the waters surface and lands in the pool. the water spray is again 10 cm above the surface of the water when it is 120 cm horizontally from the nozzle. write the quadratic function in vertex form to represent the path of the water if the orgin is at the surface of the water directly below the nozzle
