Please solve these and explain/show all your steps. Thank you for your help. 1. Using the focal length, find the equation of a parabola with a focus of (-1,-2) and a directrix of y=6.
2. Using the focal length, find the equation of a parabola with a focus of (-5,4) and a directrix of y=0.

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7

step-by-step explanation:

because i took test

1.3 million hoops i believe

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
