Answer:

Step-by-step explanation:
The directrix of the parabola is the horizontal line with the eqaution  The focus of the parabola is at point (-4,10), than the axis of symmetry of the parabola is the perpendicular line to the directrix passing through the focus. Its equation is
 The focus of the parabola is at point (-4,10), than the axis of symmetry of the parabola is the perpendicular line to the directrix passing through the focus. Its equation is  
 
The distance between the directrix and the focus is  so
 so  and the vertex is at point
 and the vertex is at point 
Parabola goes in positive y-direction, hence its equation  is 

where  is the vertex, so the equation of this parabola is
 is the vertex, so the equation of this parabola is

Answer:
height = 7.78 mm, while base = 31.11
Step-by-step explanation:
First, create the equation "4x^2=242." After doing this, solve for x. Once you do this, you will find x as 7.78. The x value is your height. To find the base, multiply height by 4.
