Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
Question
![### Norman Window Optimization Problem
A Norman window has the shape of a rectangle surmounted by a semicircle. Find the dimensions of a Norman window of perimeter 25 ft that will admit the greatest possible amount of light. (Round your answers to two decimal places.)
#### Problem Statement:
The goal is to determine the dimensions \( x \) and \( y \) of the Norman window which maximize the area while having a fixed perimeter of 25 feet.
1. **Rectangle Width (\( x \)) :**
\[
x = 2.74 \, \text{ft}
\]
2. **Rectangle Height (\( y \)) :**
\[
y = 5.47 \, \text{ft}
\]
#### Graphical Explanation:
The provided diagram by the problem comprises of:
- A rectangle with width \( x \) and height \( y \).
- A semicircle having its diameter equal to the width of the rectangle (\( x \)).
Given the visual representation:
- The width of the rectangle, denoted as \( x \), is measured horizontally.
- The height of the rectangle, denoted as \( y \), is measured vertically.
- The semicircle sits atop the rectangle and shares the same width \( x \).
The diagram helps to visualize the configuration of the Norman window, ensuring understanding of how \( x \) and \( y \) relate to the overall shape and its properties.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F456d1733-597b-47a7-bff4-881d2af765b2%2F088d8551-f20e-46a3-8cb2-5d99c4b5bd05%2Frrfsy8.png&w=3840&q=75)
