Introduction

When dealing with mathematical functions, it's essential to understand the relationship between the input and output values. In this case, we're given two functions: $V(x)=\frac{4}{3} \pi x^3$ and $W(x)=V(39 x)$ . The first function represents the volume of a sphere in cubic inches, while the second function represents the volume of the same sphere when the input value $x$ is measured in feet. Our goal is to write a rule for the function $W(x)$ that takes into account the conversion from feet to inches.

Understanding the Function $V(x)$

The function $V(x)=\frac{4}{3} \pi x^3$ represents the volume of a sphere in cubic inches. This function is a direct result of the formula for the volume of a sphere, which is $\frac{4}{3} \pi r^3$ , where $r$ is the radius of the sphere. In this case, the radius is represented by the input value $x$ . Therefore, the function $V(x)$ can be thought of as a scaling factor that multiplies the input value $x$ by $\frac{4}{3} \pi$ to obtain the volume of the sphere in cubic inches.

Understanding the Function $W(x)$

The function $W(x)=V(39 x)$ represents the volume of the sphere when the input value $x$ is measured in feet. To understand this function, we need to consider the relationship between feet and inches. Since there are 12 inches in 1 foot, we can multiply the input value $x$ by 39 to convert it from feet to inches. This is because 39 is the number of inches in 1 foot (12 inches/foot x 3.25 feet/inch). Therefore, the function $W(x)$ takes the input value $x$ in feet and converts it to inches by multiplying it by 39.

Writing a Rule for the Function $W(x)$

To write a rule for the function $W(x)$ , we need to consider the conversion from feet to inches. Since there are 12 inches in 1 foot, we can multiply the input value $x$ by 39 to convert it from feet to inches. However, we also need to take into account the scaling factor of $\frac{4}{3} \pi$ that is present in the function $V(x)$ . This scaling factor is necessary to obtain the volume of the sphere in cubic inches.

Deriving the Rule for the Function $W(x)$

To derive the rule for the function $W(x)$ , we can start by substituting the expression for $V(x)$ into the function $W(x)$ . This gives us:

W(x)=V(39 x)=\frac{4}{3} \pi (39 x)^3

Simplifying this expression, we get:

W(x)=\frac{4}{3} \pi (39)^3 x^3

W(x)=\frac{4}{3} \pi (59049) x^3

W(x)=4 \pi (19683) x^3

W(x)=78732 \pi x^3

Therefore, the rule for the function $W(x)$ is:

W(x)=78732 \pi x^3

Conclusion

In conclusion, we have derived a rule for the function $W(x)$ that takes into account the conversion from feet to inches. The function $W(x)$ represents the volume of a sphere when the input value $x$ is measured in feet, and it is related to the function $V(x)$ by a scaling factor of $\frac{4}{3} \pi$ . By understanding the relationship between the input and output values of these functions, we can write a rule for the function $W(x)$ that accurately represents the volume of the sphere in cubic inches.
