The standard equation for a parabola that opens upward parallel to the y-axis is x2=4ay, where a = distance from the vertex to focus. Vertex is at origin(0,0)
4a=2
a=2/4
a=1/2 or 0.5
the coordinate of the focus is (0, 1/2)
the equation of the directrix is y=-1/2
Answer:
Step-by-step explanation:
we know that
The roots (or x-intercepts) of the equation are
x=1 -----> with multiplicity 1
x=2 -----> with multiplicity 1
x=3 -----> with multiplicity 2 (because is a turning point)
so
The factors are
The equation is equal to

Answer:
V = 288 pi cm^3
Step-by-step explanation:
Volume of a sphere is given by
V = 4/3 pi r^3
We know the radius is 6
V = 4/3 pi 6^3
V = 4/3 pi (216)
V = 288 pi cm^3
