Hmm, y=1 is directix
means it opens up or down
we will be using
(x-h)²=4p(y-k) where (h,k) is vertex and p is the distnace from focus to vertex and from vertex to direcitx
focus is (-1,-3)
find distance between y values because directix is a y value
midpoint is the vertex
from -3 to 1 is 2 units
since focus is below directix, it opens down, and p is negative
it is 2 units above focus
so at (-1,-1)
and p=-2

(x-(-1))²=4(-2)(y-(-1))
(x+1)²=-8(y+1) is da equation

5. mc035-1.jpg What is the area of the kite? 135 m2 216 m2 90 m2 108 m2

Ahat [919]

Pls. see attachment.

9√2 → 12.73

sin θ = opposite / hypotenuse
sin 45° = opposite / 12.73
0.707 * 12.73 = opposite
9 = opposite

cos θ = adjacent / hypotenuse
cos 45° = adjacent / 12.73
0.707 * 12.73 = adjacent
9 = adjacent

Area of a kite = pq/2
p = 9 + 9 = 18
q = 9 + 6 = 15

Area = (18m*15m) / 2
Area = 270m² / 2
Area = 135 m²

The area of the kite is 135 m².
