A ball is dropped from a cliff that is 135 m high.
The relationship between the height of the ball,
h, in metres, and time, t, in seconds, can be
represented by the equation h = –4.9t
2 + 135.
Which is closest to the height of the ball after
2.1 seconds?

Answer:

113 feet

Step-by-step explanation:

I will assume you meant h = -4.9t^2 + 135; "t2" is incorrect.

To answer this question, to find the height of the ball after 2.1 seconds, substitute 2.1 for t in the above equation:

h(2.1) = -4.9(2.1)^2 + 135.  This becomes -21.6 + 135, or 113.4.

The closest result to the height of the ball after 2.1 seconds is 113 feet.
