Answer: x² = 4y -8
Step-by-step explanation: The equation of the set of points which are equidistant from a point and from a line is a parabola. In this case:
F ( 0 , 2 ) The parabola open upwards, so is of the form
p = 1
( x - h )² = 4*p* ( y - 2)
x² = 4 * ( y - 2 )
x² = 4y -8
Answer:
x^2 - 10x + 25 = 17
Step-by-step explanation:
Please use " ^ " to denote exponentation:
x^2 - 10x = -8
x^2 - 10x + 25 = 17
x^2 - 10x + 25 = -8
x^2 - 10x - 25 = -33
Begin with x^2 - 10x = -8. Here's the process for completing the square:
1. Take half of the coefficient of x and square the result:
(1/2)(-10) = -5, and then (-5)^2 = + 25
2. Add this 25 to the first two terms of x^2 - 10x = -8 and also to the constant -8: x^2 - 10x + 25 = -8 + 25, or x^2 - 10x + 25 = 17
3. Match this result to one of the given possible answers. Turns out that the given possible answer matching our result is the first one:
x^2 - 10x + 25 = 17

Area is a metric concept that can allow a measurement to be assigned to the extent of a surface, expressed in mathematics as units of measurement called surface units.
