Which points are the vertices of the ellipse?
a) points n and p
b) points o and p
c) points q and r
d) points s and t

 1. The general equation of an ellipse is shown below:

 ((x-h)²/a²)+((y-k)²/b²)=1

 2. As you can see in the graph, the center of the ellipse is (0,0),; Then, you have that the formula is:

 ((x-0)²/a²)+((y-0)²/b²)=1
 (x²/a)+(y²/b)=1

 3. The figure attached in the problem shows that the ellipse is vertical, then its vertices are the following points:

 S(0,6) and T(0,-6)

 4. Therefore the correct answer is the las option: d) Points S and T. 

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
