PLEASE HELP!!!!Question: ⇒ An object is launched from the ground. The object’s height, in feet, can be described by the quadratic function h(t) = 80t – 16t2, where t is the time, in seconds, since the object was launched. When will the object hit the ground after it is launched? ⇒ Explain how you found your answer.⇒ No spam answers, please!⇒ No wrong answers, please!Thank you!

A:
Answer:it would take 5 seconds for the object to hit the ground after launched.////////////////////////////////////////////////////////////////////////////////1st step: (turn the quadratic function to a quadratic equation by setting the equal to zero): 0 = -16t2 + 80t + 02nd step: t = 0 & t = 5(t = 0 is the time of launch. t = 5 represents the 5 seconds it took to hit the ground after the object was launched.)
