Suppose that a ball is thrown into the air with an upward velocity of 4 feet per second from a building that is 20 feet high. The equation that gives the height of
the ball above the ground at time t, in seconds, is h = 20 + 4t - 16t2.
Determine after how many seconds since the ball was released will it hit the ground?
seconds

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

it is only things thain can be deafeated
