Answer:
C, √45
Step-by-step explanation:
First, we can use process of elimination to get rid of A and D, since we know we're looking for a range, and only the highest or the lowest number is going to be outside of that range.
Now we simply have to run the remaining answers through our calculators. √62 is 7.87 and √45 is 6.71. Since 7.87 is between 7 and 8 and 6.71 is not, C must be our answer.
66 yards is greater, because in the metric system 1 yard= 3 feet. 66 yards is equal to 198 feet. Therefore, making 66 feet greater than 180 feet.
Keep in mind that, the directrix is "p" distance units away from the vertex, and the focus point is also "p" distance units from the vertex but in the opposite direction, so in short the vertex is half-way between both of them.
in this case the vertex is at the origin, and the directrix 5 units above it, so that means the parabola is vertical and opening downwards, like the one in the picture below, and the focus point is 5 units the other way.
