What is the y-value of the vertex of the function f(x) = –(x – 3)(x + 11)?
the y-value of the vertex is

Step-by-step explanation:

   Given,

   The vertex of the parabola occurs at .

For the given parabola,

So, vertex occurs at

At this point

∴ At vertex, y-value of is 49.

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

step-by-step explanation:

i googled it and this is what i got i don't know how it is. sorry.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
