(-1,1.5) because you add both ys and both xs then divide by two to find the middle
Answer:
The answer I got was 15 3/4 ft 2
Answer:

Step-by-step explanation:
Notice that the focus is a points on the vertical axis, that means the parabolla opens vertically, and has the form

Because the parameter
is positive and equal to 0.75. Additionally, the vertex is at the origin, that's why the equation is this simple.
Replacing the parameter value, we have

Therefore, the equation of a parabolla with vertex at the origin and focus at (0, 0.75) is
.
561 rounded to the nearest hundred is 600
