Where a, b, and c are real numbers and a ≠ 0 .
The quadratic term is ax
2
, the linear term is
bx, and the constant term is c. Quadratic
functions have degree two. The graph of a
quadratic function is called a parabola. If
a < 0, then the parabola opens downward,
like function g. If
a > 0, then the parabola
opens upward like function f. If
the parabola opens upward, then
the vertex is the point whose yvalue
is the minimum value of f.
If the parabola opens downward,
then the vertex is the point
whose y-value is the maximum
value of f. The vertical line that
goes through the vertex is called
the axis of symmetry of the
parabola.
The amount of the paint that Ellis needs to paint all the surfaces of the 12 fenceposts will be 226.08 square feet.
<h3>What is a cylinder?</h3>
A cylinder is a closed solid that has two parallel circular bases connected by a curved surface.
Ellis is painting wooden fenceposts before putting them in his yard. They are each 6 feet tall and have a diameter of 1 foot. There are 12 fenceposts in all.
The amount of the paint that Ellis needs to paint all the surfaces of the 12 fenceposts will be
The area of the one fence post will be
Area = πdh
Area = 3.14 x 1 x 6
Area = 18.84 square feet
Then the paint for 12 fence posts will be
Total area = 12 x 18.84
Total area = 226.08 square feet
