it's d, since the area of a circle is radius squared times pi
3.14×5^2= 78.4
Y=-4
compared to focus
(3,-7)
vertex is in middle
so
-4 and -7, the average is -5.5
so vertex is (3,-5.5)
and distance from vertex to focus is from -5.5 to -7 or 1.5
focus is below vertex is p is negative
(x-3)^2=4(-1.5)(x+5.5)
(x-3)^2=-6(x+5.5)
D is answer
<span>y-2>1/2(x-2) can be expanded as follows: y - 2 > (1/2)x - 1
Mult. all terms by 2 to remove the fractions:
2y - 4 > x - 2
Add 4 to both sides: 2y > x + 2
Div. both sides by 2: y > (1/2)x + 1 (answer)</span>
