17. The vertex form of the parabola equation is
where <em>(h,k)</em> are the coordinates of the vertex and sign "-" because parabola goes down.
In your case, vertex is (2,3), so
The vertex is 3 units from the focus, then
The equation of the parabola is
Answer:
The difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug is <u>42,739,999.999999999.</u>
Step-by-step explanation:
Given:
An environmental scientist estimated the number of drops of water in two different jugs. He estimated that the smaller jug contains 8,060,000.000000001 drops of water and the larger jug contains 50,800,000 drops of water.
Now, to find the difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug.
The smaller jug contains drops of water = 8,060,000.000000001.
The larger jug contains drops of water = 50,800,000.
Now, to get the difference between the number of drops of water we subtract the number of drops of water in the smaller jug from the number of drops of water in the larger jug:
Therefore, the difference between the number of drops of water in the larger jug and the number of drops of water in the smaller jug is 42,739,999.999999999.
