1) Solve equation r=sqrt(A/pi)
3) Give examples of quadratic relationship in either nature of business. Remember a quadratic relationship has the form V=a*x^2+b*x+c
4) Here's an example of how simple composite function is constructed. The Area A of a circle is given by A=(pi)*r^2. The volume of V of a container with a cylindrical cross-section A and height H is given by V=A*h. We can then create a composite function that gives us the volume V of the container above in terms of its radius by substituting the function for A into the function for V, as follows:
What examples can you come up with?
5) Identify and briefly discuss two concepts that you believe are best applicable to your profession.
r = sqrt(A/pi)
=> r^ = A/pi
=> A = pi*r^2 --ANSWER
Ellipse: Orbit of the Earth around the Sun, The Whisper Chamber (USA)
Parabola: Reflecting surfaces of mirrors and dish antennae, path traced by an object projected at an acute angle with horizontal
Hyperbola: Lamp shade on wall, transmission gear, cooling tower of ...
Here are a few problems related to geometry and application of quadratic equation are solved.
