What is the vertex of y=(x+2)(x-2)

If we write the quadratic equation in the vertex form, will be easy to find the vertex.

The vertex form of a quadratic function is:

Where the vertex is (h. k).

We have:

y=(x+2)(x-2)

Form this we conclude: a = 1, h = 0, k = -4. Then:

i can try and you the very best that i can.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
