The general form for a parabolic dish is:
y=x^2/(4f), where f=focus' y coordinate when x=0
So if you are given the equation:
8y=x^2, you need only to rearrange it to the form y=x^2/(4f)
y=x^2/8
Since 8=4f, f=2 inches and the focal point of course (0,2)
Answer:
B
Step-by-step explanation:
180 - y + z = x {Exterior angle property}
z = x - 180 + y
z = x + y - 180
Let, Jason = J and M = Megan
M = J(1 + 1/4)
So putting 6 where J is and solving:
<em>M = 6(1 + 1/4)
</em><em>M= 7.5</em>
When Jason runs 6 miles Megan runs 7.5
