Answer: Option (d) is the correct answer.
Explanation:
A tetarhedral geometry is the geometry which includes four atoms bonded to the central atom and it does not contain any lone pair of electron.
For example, has tetrahedral geometry.
Thus, we can conclude that a molecule which contains four bonded pairs of electrons and zero lone pairs. The name of the molecular geometry is tetrahedral.
the equation of the parabola is given as . D
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
