What is the directrix and focus of the parabola 6y-x^2=0

now, the coefficient for the squared variable, namely for x², is positive, that simply means the parabola opens upwards, and that is where the focus is at, and the directrix is on the opposte way.

notice, h,k is 0,0, so the parabola's vertex is at the origin, and from there, we move "p" units UP to get the focus point, at   , and then we move DOWN "p" units to get the directrix at  

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p
