Answer:
4 m
Step-by-step explanation:
The equation can be written ...
y = (x/4)² = (1/16)x²
where the divisor 4 is the horizontal scale factor that makes the parabola 8 m wide at y = 1 m.
This can also be written as ...
y = 1/(4p)x² = (1/16)x²
from which we can see ...
4p = 16
p = 4
In this form, p is the distance from the vertex to the focus, 4 meters.
_____
Another way to find the y-coordinate of the focus is to draw a line with slope 1/2 through the vertex. It will intersect the parabola at the point where the vertical distance to the directrix is the same as the horizontal distance to the focus. The y-coordinate of that point is the y-coordinate of the focus.
Vol of small ball = 4/3 pi (2.5)^3
Vol of larger on = 4/3 pi (6.5)^3
Difference = 4//3pi(6.5^3-2.5^3)
= 4/3 pi (259)
= 1085.0
Same side interior angles have a sum of 180 degrees
49 + x = 180 degrees
x = 180 - 49 = 131 degrees
Solution: 131 degrees
