Understanding the Problem

The problem presents a relationship between two variables, x and y, where the value of y is described as five times one-third raised to the power of x. This relationship can be expressed mathematically as an equation. In this article, we will explore the different options provided and determine which equation accurately describes the given relationship.

Analyzing the Options

Option A: $y=\frac{1}{3} \cdot 5^x$

This option suggests that the value of y is equal to one-third multiplied by 5 raised to the power of x. However, this does not accurately represent the relationship described in the problem. The problem states that y is five times one-third raised to the power of x, not one-third multiplied by 5 raised to the power of x.

Option B: $y=\left(5 \cdot \frac{1}{3}\right)^x$

This option suggests that the value of y is equal to the expression inside the parentheses raised to the power of x. The expression inside the parentheses is 5 multiplied by one-third, which is equivalent to 5/3. Therefore, this option can be rewritten as $y=\left(\frac{5}{3}\right)^x$ . This option accurately represents the relationship described in the problem, where y is five times one-third raised to the power of x.

Option C: $y=5 x^3$

This option suggests that the value of y is equal to 5 multiplied by x cubed. However, this does not accurately represent the relationship described in the problem. The problem states that y is five times one-third raised to the power of x, not 5 multiplied by x cubed.

Option D: $y=5 \cdot \frac{1}{3} x$

This option suggests that the value of y is equal to 5 multiplied by one-third multiplied by x. However, this does not accurately represent the relationship described in the problem. The problem states that y is five times one-third raised to the power of x, not 5 multiplied by one-third multiplied by x.

Conclusion

Based on the analysis of the options, it is clear that only one option accurately represents the relationship described in the problem. Option B, $y=\left(5 \cdot \frac{1}{3}\right)^x$ , is the correct equation that describes the relationship between x and y. This equation accurately represents the relationship described in the problem, where y is five times one-third raised to the power of x.

Why is Option B the Correct Answer?

Option B is the correct answer because it accurately represents the relationship described in the problem. The expression inside the parentheses, 5 multiplied by one-third, is equivalent to 5/3. Therefore, this option can be rewritten as $y=\left(\frac{5}{3}\right)^x$ . This equation accurately represents the relationship described in the problem, where y is five times one-third raised to the power of x.
