Hi!
So we all know diameter is the width across the circle and radius is half of the diameter.
So since we know what diameter is, that would make #1) AC or the second option
For number two in case you don't know, angles 6 and 7 are vertical angles. Which, are CONGRUENT! YAY! That always makes it so easy! So if angle 6 is 30°, angle 7 will be, YES!! 30°! So easy!
So the answer to #2) 30<span>°</span>, or 4th option!
Hope I helped!
Standard form is, hold a sec
x=2 is directix
that means it opens left or right
so we must use
(y-k)²=4p(x-h)
where vertex is (h,k) and p is distance from focus to vertex
also shortest distance from vertex to directix
the shortest distance from focus to directix is 2p
if p>0 then the parabola opens right
if p<0 then pareabola opens left
so
(-2,0) and x=2
the distance is 4
4/2=2
p=2
wait, positive or negative
focus is to the left of the directix so p is negative
p=-2
vertex is 2 to the right of the focus and 2 to the left of directix
vertex is (0,0)
so
(y-0)²=4(-2)(x-0) or
y²=-8x is da equation
not sure what form is standard tho
