the equation of the parabola is given as 
. D
<h3>How to find the parabola</h3>
Given the focus(6,2) and the directrix, y = 0
Use the formula
= (y - 0)
Find the square of both sides, square root is removed from the side with it and square added on the other side
Expand the expression and bring all terms to one side
= 
Collect like terms
Make 'y' the subject of the formula
Divide through by 4 and substrate 4 from 40 to give a perfect quadratic equation
Divide factor by 4 to give 1
Simplify the expanded quadratic equation
, we have 
Then insert in place into previous equation
Thus, the equation of the parabola is given as

<h3><u>Answer</u>;</h3>
No, a precipitate does not form
<h3><u>Explanation</u>;</h3>
- Precipitation involves mixing or combining solutions that contain soluble ionic compounds to form an insoluble ionic compound by a reaction.
- Sodium acetate and ammonium sulfate are both soluble ionic compounds, which implies that they exist as ions in aqueous solution.
- <em><u>When they combine they form NH4CH3COOH and sodium sulfate, Na2SO4, which are both soluble salts, as all salts of ammonium and sodium are soluble.</u></em>
- <em><u>Both ammonium acetate and sodium sulfate are soluble because there are no anions that can form an insoluble solid with NH4+ and Na+ cations. </u></em>
