To interpret the height of the school's roof based on the given equation \(y = -16t^2 + 40\), we can analyze the equation:

In the equation:

  • \(y\) represents the height (in feet),
  • \(t\) represents the time (in seconds),
  • and the constant term, \(40\), indicates the maximum height from which the egg is dropped.

When the time \(t = 0\), the height \(y\) is:

\[ y = -16(0)^2 + 40 = 40 \text{ feet} \]

Therefore, the height of the school's roof can be correctly interpreted as 40 feet.

So, the correct response is:

40 feet.
