The polynomial –16t2 + vt + h0 models the height, in feet, of a ball t seconds after it is thrown. In this polynomial, v represents the initial vertical velocity of the ball and h0 represents the initial height of the ball.Min throws a baseball from a height of 6 feet with an initial vertical velocity of 30 feet per second. Which polynomial models the height of the ball, in feet?
The model is −16t² + vt + h₀, where v is the initial vertical velocity and h₀ is the initial height. Substituting v = 30 and h₀ = 6 gives −16t² + 30t + 6. Therefore, the correct choice is D, −16t² + 30t + 6.
