What is the equation of a parabola with a focus (-2,4) and directrix y = 0?
Ronch [10]
The general form of a parabola  when using the focus and directrix is:
(x - h)² = 4p(y - k) where (h, k) is the vertex of the parabola and 'p' is distance between vertex and the focus.  We use this form due to the fact we can see the parabola will open up based on the directrix being below the focus.  Remember that the parabola will hug the focus and run away from the directrix.  The formula would be slightly different if the parabola was opening either left or right.

Given a focus of (-2,4) and a directrix of y = 0, we can assume the vertex of the parabola is exactly half way in between the focus and the directrix.  The focus and vertex with be stacked one above the other, therefore the vertex will be (-2, 2) and the value of 'p' will be 2.  We can now write the equation of the parabola:
(x + 2)² = 4(2)(y - 2)
(x + 2)² = 8(y - 2)  Now you can solve this equation for y if you prefer solving for 'y' in terms of 'x'

Use the given information to answer the following questions. center (3, -9, 3), radius 5 (a) Find an equation of the sphere with
lianna [129]

Answer: The equation of the sphere with the center and radius

x^{2} +y^{2} +z^{2}-6 x+18 y-6 z+74=0

b) The intersection of this sphere with the y z-plane the x- co-ordinate

is zero(i.e., x = 0 )

Step-by-step explanation:

a) The equation of the sphere having center (h,k,l) and radius r is

(x-h)^{2} +(y-k)^2+(z-l)^2 = r^2

Given center of the sphere  (3, -9, 3) and radius 5

(x-3)^{2}+(y+9)^2+(z-3)^2 = 5^2

on simplification , we get solution

x^{2} -6 x+9+y^{2} +18 y+81+z^{2}-6 z+9=25

x^{2} +y^{2} +z^{2}-6 x+18 y-6 z+74=0

Final answer :-

x^{2} +y^{2} +z^{2}-6 x+18 y-6 z+74=0

b) The intersection of this sphere with the y z-plane the x- co-ordinate

is zero(i.e., x = 0 )

y^{2} +z^{2}+18 y-6 z+74=0

What Is the answer to 10ac-x/11=-3
cestrela7 [59]
  1. Multiplty both sides by 11. 11 times 11 cancels out, 11 times -3 equals -33. You should get 10ac - x = -33
  2. Add  x  to both sides:   10 a c = x − 33
  3. Divide both sides by  10 c :   a = x − 33 /10c

revised tada!
