Consider a window the shape of which is a rectangle of height h surmounted a triangle having a height T that is 0.8 times the width w of the rectangle (as shown in thefigure below).
(5) The cross-section of a tunnel is a rectangle of height h surmounted by a semicircular roof section of radius r. If the cross-sectional area is A, determine the dimensions of the cross-section which minimize the perimeter when A= 8m2. Make sure to (a) Round your answer to two decimal places. (b) Justify that your values produce a global minimum. (c) Answer the specific question asked.
java language Problem 3: Shape (10 points) (Software Design) Create an abstract class that represents a Shape and contains abstract method: area and perimeter. Create concrete classes: Circle, Rectangle, Triangle which extend the Shape class and implements the abstract methods. A circle has a radius, a rectangle has width and height, and a triangle has three sides. Software Architecture: The Shape class is the abstract super class and must be instantiated by one of its concrete subclasses: Circle, Rectangle, or...

Project 1 – Classes and Top-down Design Overview Software development projects using the object-oriented approach involve breaking the problem down into multiple classes that can be tied together into a single solution. In this project, you are given the task of writing some classes that would work together for providing a solution to a problem involving some basic computations. Learning Objectives The focus of this assignment is on the following learning objectives: • Be able to identify the contents of...
