Answer:
To solve this problem, we can use a system of equations.
We know the quadratic expression has the form

Using points (1,12) and (4,0), we can form the following system to find a and b.


We need to divide the second equation by -4 and sum both equations


Then, we use this value to find the other variable

<h3>Therefore, the quadratic function that models the situation is</h3>
or 
According to this expression, after 2 seconds, the height is 16 feet.

The expression (n+3) represents the measure of an exterior angle of a regular octadecagonal.
Substitute 22 for x
