Mr. Alim's science class launched a toy rocket from the ground level with an initial upward velocity of 60 feet per second. The height h of the rocket in feet above the ground after t seconds is modeled by the equation h=60t-60t². How long was the rocky in the air before it returned to the ground? 3.75 seconds

Sample response: the vertex lies on the axis of symmetry, so the axis of symmetry is x = 3. find any two x-intercepts that are equal distance from the axis of symmetry. use those x-intercepts to write factors of the function by subtracting their values from x. for example, 2 and 4 are each 1 unit from x = 3, so f(x) = (x – 2)(x – 4) is a possible function. which points did you include in your response? check all that apply.

The triangles are similar. what is the value of x? show your work.
