To determine the equation of the parabola with the given features above, we need to understand or know what are the significance of those values. The directrix is a line that is perpendicular to the axis of symmetry of a curve. A parabola is defined by its focus and the directrix. The parabola is a group of points where the distance to its focus is equal to the distance to its directrix. So, the directrix for this case is all points (x, -1). By using the distance formula, we construct the equation.
√((x-0)^2 + (y-1)^2) = √((x-x)^2 + (y+1)^2)
x^2 + (y-1)^2 = (y+1)^2
x^2 + y^2 - 2y+1 = y^2 +2y + 1
x^2 - 2y = 2y
x^2 = 4y
y = x^2/4
Answer:
The answer is 48pi
Step-by-step explanation:
Circumference: C=2*pi*radius
The radius of Circle B is 2*12=24
Thus, the circumference of Circle B is: 2*pi*24=48pi
Answer:
x=2
Step-by-step explanation:
How many seconds are in a minute? 60 seconds. So you do 60•5.71 and once you get the answer,you multiply that by 60 again because there is 60 minutes in 1 hour.Then you will have your final answer!
