A quadratic function is one of the form f(x) = ax2 + bx + c, where a, b, and c are numbers with a not equal to zero. The graph of a quadratic function is a curve called a parabola. ... A parabola intersects its axis of symmetry at a point called the vertex of the parabola. You know that two points determine a line.
5n + 34 = -2(1 - 7n)
5n + 34 = -2 + 14n
5n = -36 + 14n
-9n = -36
9n = 36
n = 4
Answer:

Step-by-step explanation:
We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is
.
Because all the angles of a triangle sum to
, we have that
.
We combine like terms on the left side to get
.
We subtract
on both sides to get
.
So,
and we're done!
Answer:
x=50
Step-by-step explanation:
A parent function is the simplest function of a family of functions that preserves the definition (or shape) of the entire family.
