I got x = 96/18 i dont think the answer is there
You can use a proportion.
4 hours is to 82 miles as 14 hours is to x miles
4/82 = 14/x
Cross multiply to get
4x = 14 * 82
4x = 1148
x = 287
287 miles
General equation of parabola
for vertex(h,k)
Now





So
equation of parabola

You can drag in the first empty box ∡3 and get ∡2≅∡3.
In the second box you can drag '' definition of angle bisector ''.
In the third empy box you can drag ∡1 and get ∡1≅∡3.
At last empy box you can drag ''transitive property of congruence''
Good luck!!!
10 and -7 times each other equals -70.
10 plus -7 equals 3.
Hope this helps you! (:
