Ineed with all of these. i am in online school so i don't have a teacher to explain this to me and am struggling.

1.)what is the directrix of the parabola given by the equation r= 2/1+sinθ ?
rsinθ = 2
sinθ = 2
rcosθ = 2
r = 2
2.) choose the equation of the conic section described. a parabola with focus at the pole and directrix rsinθ = - 5
3.)choose the equation of the conic section described.
focus at the pole, eccentricity of 2/3, vertical directrix 2 units to the left of the pole
4.)write the equation of the conic section satisfying the given conditions.
focus at the pole, e = 3/4, horizontal directrix 2 units above the pole
5.)the equation of a parabola is r= 6/1+cosθ. the vertex of the parabola is located at
(3, 0°)
(6, 0°)
(3, 180°)
(6, 180°)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.

step-by-step explanation:

if you want to separate 54 into 6 individual tiers then you need to divide if you want to separate 54 into 6 individual tiers then you need to divide 6 and 54.

if you divide 9 by 6 you will get 54.
