Here is how the Earlier Census Date for Geometric Increase Method equation looks like.

20.3454 = 29 - (\frac{\log 10 (40) - \log 10 (22)}{0.03})

20.3454 = 29 - (\frac{\log 10 (40) - \log 10 (22)}{0.03})

20.3454 = 29 - (\frac{\log 10 (40) - \log 10 (22)}{0.03})

Earlier Census Date for Geometric Increase Method Solution

Follow our step by step solution on how to calculate Earlier Census Date for Geometric Increase Method?

FIRST Step Consider the formula

T E = T M - (\frac{\log 10 (P M) - \log 10 (P E)}{K G})

Next Step Substitute values of Variables

∴

T E = 29 - (\frac{\log 10 (40) - \log 10 (22)}{0.03})

Next Step Prepare to Evaluate

∴

T E = 29 - (\frac{\log 10 (40) - \log 10 (22)}{0.03})

Next Step Evaluate

∴

T E = 20.3454229831415

LAST Step Rounding Answer

∴

T E = 20.3454
