Question

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?

14t^2+6
-16t^2+36t
-16^2+6t+30
-16t^2+30 +6

Answer 1

D. -16t^2 + 30t + 6

Explanation:

Answer 2

Well if the equation is -16t^2 + vt + h0,

and we know v = 30, because that's the velocity,

and we also know h0 = 6 because that's the height,

then the equation will read: -16t^2 + 30t + 6
