Which function is a quadratic function

Mathematics
1 answer:
Pavlova-9 [17]3 years ago
5 0
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.

If h(x) = 6 – x, what is the value of (h circle h) (10)
Andrew [12]

Answer:

10

Step-by-step explanation:

h(x) = 6 - x

(h o h)(x) = h(h(x)) = 6 - h(x) = 6 - (6 - x) = 6 - 6 + x = x

(h o h)(x) = x

(h o h)(10) = 10

K<br> M<br> N<br> L <br>Radius:13<br> Diameter:26 cm <br>Circumference:?<br> Area:?
Step2247 [10]

Answer:

Given radius (R) = 13

Diameter =  2R =  26

Circumference =  2πR

=  26π

=  81.681408993335

Area =  πR2

=  169π

=  530.92915845668

Step-by-step explanation:

While a circle, symbolically, represents many different things to many different groups of people including concepts such as eternity, timelessness, and totality, a circle by definition is a simple closed shape. It is a set of all points in a plane that are equidistant from a given point, called the center. It can also be defined as a curve traced by a point where the distance from a given point remains constant as the point moves. The distance between any point of a circle and the center of a circle is called its radius, while the diameter of a circle is defined as the largest distance between any two points on a circle. Essentially, the diameter is twice the radius, as the largest distance between two points on a circle has to be a line segment through the center of a circle. The circumference of a circle can be defined as the distance around the circle, or the length of a circuit along the circle. All of these values are related through the mathematical constant π, or pi, which is the ratio of a circle's circumference to its diameter, and is approximately 3.14159. π is an irrational number meaning that it cannot be expressed exactly as a fraction (though it is often approximated as 22/7) and its decimal representation never ends or has a permanent repeating pattern. It is also a transcendental number, meaning that it is not the root of any non-zero, polynomial that has rational coefficients. Interestingly, the proof by Ferdinand von Lindemann in 1880 that π is transcendental finally put an end to the millennia-old quest that began with ancient geometers of "squaring the circle." This involved attempting to construct a square with the same area as a given circle within a finite number of steps, only using a compass and straightedge. While it is now known that this is impossible, and imagining the ardent efforts of flustered ancient geometers attempting the impossible by candlelight might evoke a ludicrous image, it is important to remember that it is thanks to people like these that so many mathematical concepts are well defined today.
