The Dimensions of a Portable Kennel: A Mathematical Exploration
In this article, we will delve into the world of mathematics and explore the dimensions of a portable kennel. Given the width, length, and height of the kennel as functions of a variable x, we will use a graphing calculator to find the dimensions of the kennel with a volume of 7.4 ft^3.
The dimensions of a portable kennel can be expressed as:
- Width:
- Length:
- Height:
We are given that the volume of the kennel is 7.4 ft^3. Our goal is to find the value of x that satisfies this condition.
The volume of a rectangular prism, such as the portable kennel, is given by the formula:
V = lwh
where V is the volume, l is the length, w is the width, and h is the height.
In this case, the volume is 7.4 ft^3, the length is x + 0.4, the width is x, and the height is x - 0.2. Substituting these values into the formula, we get:
7.4 = (x + 0.4)x(x - 0.2)
To simplify the equation, we can expand the right-hand side:
7.4 = x^3 + 0.4x^2 - 0.2x^2 - 0.16x
Combine like terms:
7.4 = x^3 + 0.2x^2 - 0.16x
To find the value of x that satisfies the equation, we can graph the function:
f(x) = x^3 + 0.2x^2 - 0.16x - 7.4
Using a graphing calculator, we can plot the graph of the function.
To find the solution, we need to find the x-intercept of the graph. The x-intercept is the point where the graph crosses the x-axis, which means that the y-coordinate is zero.
Using the graphing calculator, we can find the x-intercept by pressing the "intersect" button and selecting the x-axis as the intersection point.
The x-intercept is approximately x = 2.1.
To check the solution, we can substitute x = 2.1 into the original equation:
7.4 = (2.1 + 0.4)(2.1)(2.1 - 0.2)
Simplifying the equation, we get:
7.4 = 2.5(2.1)(1.9)
7.4 = 9.975
Since the equation is not satisfied, we need to try another value of x.
Let's try x = 2.2.
Substituting x = 2.2 into the original equation, we get:
7.4 = (2.2 + 0.4)(2.2)(2.2 - 0.2)
Simplifying the equation, we get:
7.4 = 2.6(2.2)(2.0)
7.4 = 11.52
Since the equation is not satisfied, we need to try another value of x.
Let's try x = 2.0.
Substituting x = 2.0 into the original equation, we get:
7.4 = (2.0 + 0.4)(2.0)(2.0 - 0.2)
Simplifying the equation, we get:
7.4 = 2.4(2.0)(1.8)
7.4 = 8.64
Since the equation is not satisfied, we need to try another value of x.
Let's try x = 2.05.
Substituting x = 2.05 into the original equation, we get:
7.4 = (2.05 + 0.4)(2.05)(2.05 - 0.2)
Simplifying the equation, we get:
7.4 = 2.45(2.05)(1.85)
7.4 = 9.0475
Since the equation is not satisfied, we need to try another value of x.

Simplifying the equation, we get:
7.4 = 2.45(2.05)(1.85)
7.4 = 9.0475
Since the equation is not satisfied, we need to try another value of x.
