Math Problem Statement

Using the computed slope and y-intercept of the line 0.0226Years+0.726, write out the best fitting exponential model. Production=__________________^years

Solution

The equation provided is linear: 0.0226×Years+0.7260.0226 \times \text{Years} + 0.726. To write the best-fitting exponential model, we need to transform the linear equation into an exponential form. An exponential equation generally has the form:

Production=A×BYears\text{Production} = A \times B^{\text{Years}}

Here’s how you can derive the exponential form:

  1. Rewrite the linear equation as: y=0.0226×Years+0.726y = 0.0226 \times \text{Years} + 0.726

  2. In an exponential model, the production should grow (or decay) at a constant rate. To estimate an exponential model based on the slope, one common approach is to express the equation in terms of a power function using an approximation.

  3. To convert a linear model to exponential, you may use a method like the following:

    Production=e0.0226×Years+0.726\text{Production} = e^{0.0226 \times \text{Years} + 0.726}

  4. Simplify this into the form A×BYearsA \times B^{\text{Years}}: Production=e0.726×(e0.0226)Years\text{Production} = e^{0.726} \times \left( e^{0.0226} \right)^{\text{Years}}

    Here, A=e0.726A = e^{0.726} and B=e0.0226B = e^{0.0226}.

  5. Calculate AA and BB:

    • A=e0.7262.067A = e^{0.726} \approx 2.067
    • B=e0.02261.0229B = e^{0.0226} \approx 1.0229

So the best-fitting exponential model would be:

Production=2.067×1.0229Years\text{Production} = 2.067 \times 1.0229^{\text{Years}}

Would you like more details on how this transformation was done, or have any other questions?

Here are 5 related questions to deepen your understanding:

  1. What is the difference between linear and exponential growth models?
  2. How does the slope in a linear equation affect its exponential counterpart?
  3. Can you convert any linear model to an exponential one? Why or why not?
  4. What real-world examples require an exponential model instead of a linear one?
  5. How do you interpret the constants AA and BB in an exponential model?

Tip: Exponential models are especially useful for situations involving growth rates, like population growth or compound interest, where changes happen by multiplying rather than adding.
