The path that Gloria follows when she jumped is a path of parabola.
The equation of the parabola that describes the path of her jump is 
The given parameters are:


<em>Assume she starts from the origin (0,0)</em>
The midpoint would be:



So, the vertex of the parabola is:

Express properly as:

Plug in the given numbers (x) to the equation.
For example, let's take the first value it gives us.
-10(-2) +y=4
20+y=4
y=-16
Then you would put that on the table, and plug in the next value(s).
Hope this helped!
Answer:
a = 64
Step-by-step explanation:
The geometric mean of 2 numbers a and b is
, then
= 16
( square both sides )
28a = (16
)² = 1792 ( divide both sides by 28 )
a = 64
