Population at Earlier Census given Proportionality Factor Solution

STEP 0: Pre-Calculation Summary

Formula Used

Population at Earlier Census = exp(log10(Population at Last Census)-(Last Census Date-Earlier Census Date)*Proportionality Factor)
P_E = exp(log10(P_L)-(T_L-T_E)*K_G)
This formula uses 2 Functions, 5 Variables

Functions Used

log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)
exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Population at Earlier Census - The Population at Earlier Census refers to the population at the earlier census date.
Population at Last Census - The Population at Last Census refers to the population at the date of last census.
Last Census Date - The Last Census Date refers to the date at which the population is noted.
Earlier Census Date - The Earlier Census Date refers to the date at which the population is noted.
Proportionality Factor - Proportionality Factor is defined as rate of change of population.

STEP 1: Convert Input(s) to Base Unit

Population at Last Census: 20.01 --> No Conversion Required
Last Census Date: 19 --> No Conversion Required
Earlier Census Date: 20 --> No Conversion Required
Proportionality Factor: 0.03 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_E = exp(log10(P_L)-(T_L-T_E)*K_G) --> exp(log10(20.01)-(19-20)*0.03)

Evaluating ... ...

P_E = 3.78576162522923

STEP 3: Convert Result to Output's Unit

3.78576162522923 --> No Conversion Required

FINAL ANSWER

3.78576162522923 ≈ 3.785762 <-- Population at Earlier Census
