A girl drops a ball off a cliff into the ocean. The polynomial −8t2+350 gives the height, in feet, of the ball t seconds after it is dropped from a 350ft tall cliff. Find the height, in feet, after t=2 seconds.

318 feet.

Step-by-step explanation:

We have been given that a girl drops a ball off a cliff into the ocean. The polynomial gives the height, in feet, of the ball t seconds after it is dropped from a 350 ft tall cliff. We are asked to find the height in feet after 2 seconds.

To find the height after 2 seconds, we will substitute in our given equation as:

Therefore, the height will be 318 feet after 2 seconds.
