Answer:
Step-by-step explanation:
We have that the focus is at (p,0) and that the directrix is x=-p. Take the point (-p,0) of the directrix. We know that the vertex of the parabola is at the middle point ot the line segment that joins the points (p,0) and (-p,0). To get the middle piont, we take the average coordinate by coordinate. That is, the middle point is 
. The general formula of a parabola of vertex (h,k) that opens to the right or to the left is given by
Where |p| is the distance from the focus to the vertex. If the parabola opens to the right, then p>0 and p<0 otherwise. In our case, h =0=k, so we get that
16. C. 0 means it is at sea level. The question is asking about the elevation of each of the places. 1.3 means the elevation is 1.3 km. If I am wrong than the only other possibility is A.
17. C.Our total will come in the beginning : e = . 40,000 is your base salary so he will get 40,000 no matter what. He also gets $200 per car and per is multiplying so 200 • c. That will be added to our base salary and our equation will be : e = 40,000 + 200 • c.
