Answer:
0.75 rounded is 0.80 and 5.25 rounded is 5.30 and add 0.80+5.30=6.10
Step-by-step explanation:
The circumference will be 18.683
Answer:

Step-by-step explanation:
Given the directrix is vertical, the parabola must have a horizontal axis since it's perpendicular to the directrix.
Therefore, we can use the form
where the focus is
and the directrix is
.
Therefore:




So:



This means that the parabola opens to the left since
. Remember that
describes the distance between the vertex and focus point.
We can tell that
given the focus point
In conclusion, the equation of the parabola is 
Answer:
(2,-2)
Step-by-step explanation:
Point A is 2 units to the right of the origin so the x coordinate is 2
It is also 2 units down so the y coordinate is -2
The point is (x,y) so A = (2,-2)
