The motion of the rock thrown from the cliff which goes downwards due to
the gravitational force, is a free fall motion.
- 125 represents; <u>A. The initial height of the rock</u>.
Reasons:
The given function that represents the height of the of the rock in feet <em>x</em> seconds after being thrown is; f(x) = 16·x² + 4·x + 125
At the initial height before being thrown from the cliff, we have;
The time, x = 0
The initial height is therefore;
The initial height f(0) = 16 × (0)² + 4 × (0) + 125 = 125
125 represents <u>A. The initial height of the rock</u>

Answer:
A. The number of students that the club needs is at least (18).
Step-by-step explanation:
27 is the minimum requirement, so they need at <em>least</em><em> </em>18 people to meet said requirement. They can go over the limit.
The other answer comes into play if 27 was the <em>maximum</em><em> </em>that was allowed. Then they would need at most 18, because they can't admit any more people. They can't go over the limit.
