Which ordered pair cannot be a solution of h(t)=-16^2+80t if h is the height of a ball above ground after r seconds?

Answer 1

The equation given in the question is not correct. It should be

h(t) = -16t² + 80t

If you have a list ordered pairs, test them by substituting the given (t,h) values into the correct equation, or solve the equation using the quadratic formula, get the the correct solutions, and reject any choices that do not agree with the correct solutions.
