It will take the roller coaster 171.652 seconds to pass over the hill and reach ground level
<h3>How to determine the time to hit the ground?</h3>
The function is given as:
h = –.025t^2 + 4t + 50
Set h = 0.
So, we have:
–.025t^2 + 4t + 50 = 0
Using a graphing calculator, we have:
t = -11.652 and t = 171.652
Time cannot be negative.
So, we have:
t = 171.652
Hence, it will take the roller coaster 171.652 seconds to pass over the hill and reach ground level

- V = 1/2(15 + 37)(25.7)(20) = 13364 cm³
Answer:
Step-by-step explanation:
1 = 1/16 (one chance on 16
2 = 7/16 (the non shaded parts are 7, while the total parts are 16)
3 = 11/16 ( 11 is unshaded + even)
4 = 4/16 = 1/4 (the favourable possibilities are: 13, 14, 15, 16)
