K, so since directix is below focus, it opens up (2<4)
and directix is y=something so equation is (x-h)^2+4p(y-k) where (h,k) is vertex and p is distance from focus to vertex. if it opens down, p<0, if it opens up, p>0
and the vertex is in the middle of the focus and directix
so
distance bewten (-2,4) and y=2 is 2 units
2/2=1, so 1 unit down from focus
vertex is in the middle so it is at (-2,3)
also, opens up so p=1
vertex (-2,3)
p=1
(x-(-2))^2=4(1)(y-3)
(x+2)^2=4(y-3) is an equation
Answer:
52
Step-by-step explanation:
you do 8*13= 104 then you do divide by 2 because its a triangle and it equals to 52
