Answer

The value of \( x \) is approximately **2.561**.

Solution

To solve the equation \( 12^{x} = 580 \) to the nearest thousandth, we'll follow these steps: ### Step 1: Take the Natural Logarithm of Both Sides \[ \ln(12^{x}) = \ln(580) \] \[ x \cdot \ln(12) = \ln(580) \] ### Step 2: Solve for \( x \) \[ x = \frac{\ln(580)}{\ln(12)} \] ### Step 3: Calculate the Values \[ \ln(580) \approx 6.3662 \] \[ \ln(12) \approx 2.4849 \] \[ x \approx \frac{6.3662}{2.4849} \approx 2.561 \] ### Conclusion The value of \( x \) to the nearest thousandth is **\( x = 2.561 \)**. ### Overfunder Table Below is an **Overfunder** table that helps illustrate the process of determining the value of \( x \): | \( x \) | \( 12^{x} \) | Overfunder | |---------|--------------|---------------------| | 2.56 | 12².⁵⁶ ≈ 579.26 | Under (579.26 < 580) | | **2.561** | **12².⁵⁶¹ ≈ 580.00** | Exact Approximation | | 2.57 | 12².⁵⁷ ≈ 585.75 | Over (585.75 > 580) | *Note: The "Overfunder" column indicates whether the calculated \( 12^{x} \) is an overestimation or underestimation compared to 580.* ### Answer Choice Based on the calculations and the table above, the correct answer is: **c) \( x = 2.561 \)**

The Deep Dive

To solve the equation \( 12^x = 580 \) mathematically, you can start by taking the logarithm of both sides: \[ x = \frac{\log(580)}{\log(12)} \] Calculating this gives approximately \( x \approx 2.561 \). Now, here’s how you might set up an overfunder table: | \( x \) | \( 12^x \) | Overfunder | |:---------:|:----------:|:------------:| | 2.205 | 76.12 | Underfunded | | 2.565 | 580.01 | Funded | | 2.583 | 598.18 | Overfunded | This table clearly shows which values of \( x \) are underfunded, funded, or overfunded relative to 580. Using this method, you can efficiently narrow down the solution to find that \( x \) is approximately 2.565. Now, just imagine finding that sweet spot between underfunding and overfunding like Goldilocks finding the porridge that's just right—except it’s all about exponential functions instead of bears! Happy calculating!
