Convert the equation [tex]f(t) = 210(1.31)^t[/tex] to the form [tex]f(t) = ae^{kt}[/tex].

Write your answer using function notation and round all values to three decimal places.

Answer :

The equation f(t) = 210(1.31)^t can be written in the form f(t) = ae^(kt), where a = 210 and k ≈ 0.265 (rounded to three decimal places).

To convert the equation f(t) = 210(1.31)^t to the form f(t) = ae^kt, we need to rewrite it in terms of the base e instead of the base 1.31.

Now, let's break down the computation into steps:

Step 1: Rewrite the equation using the natural base e

The equation f(t) = 210(1.31)^t can be rewritten using the natural base e by applying the logarithmic property:

f(t) = 210(e^(ln(1.31))^t.

Step 2: Simplify the equation

Since ln(1.31) is a constant value, we can simplify the equation further:

f(t) = 210(e^(kt)).

Here, k = ln(1.31).

Therefore, the equation f(t) = 210(1.31)^t can be written in the form f(t) = ae^(kt), where a = 210 and k ≈ 0.265 (rounded to three decimal places).

By following these steps, you can convert the given equation to the form f(t) = ae^(kt), where a and k are the corresponding values determined from the original equation.
