May’s class is testing their egg protection contraptions by dropping them off the roof of their school. Use GeoGebra to graph the situation using the formula y=−16t2+40

Question

. Which of the following correctly interprets the height of the school’s roof?(1 point)
Responses

40 feet
40 feet

41 feet
41 feet

15 feet
15 feet

20 feet

Answer 1

In the given equation \( y = -16t^2 + 40 \), \( y \) represents the height of the egg contraption at time \( t \), where \( t \) is measured in seconds.

When \( t = 0 \) (the moment the contraption is dropped), the equation gives:

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

Thus, the height of the school’s roof is 40 feet.

So, the correct interpretation is:

40 feet.
