All parabolas?
explanation:
Neato
assuming you mean

remember
in form

a is leading coficient
(h,k) is vertex
k will be the minimum or max value of the function
if a is positive, then the parabola opens up and k is minimum
if a is negative, then the parabola opens down and k is max
given
a is negative
the parabola opens down and k is the max value
it is -3
the max value is -3, which occors at x=2
g(2)=-3 is max
Try 86.36%, I hope this helps!
The volume of a cone, V(cone), is given by the following formula:
V(cone) = (1/3)Bh, where B is the area of the circular base and h is the height of the cone. The area B of the base is given by the formula B = πr², where r is the radius of the circular base; Therefore, substituting for B, the volume of a cone becomes:
Answer:
Angle y is also 40 degrees. Angle x and y are vertical angles, thus they have the same angle measure.
