The population P of a small town, measured in hundreds, is modeled by the inverse of the function P−1(t) = 10ln(50t − 1000), whe

re t is measured in years. Find the equation to model the population and determine its initial value.
P = 5t +100 where P(0) = 100
P = 1/50 In(0.1t)+20
P = 1/500e^t + 20
P = 1/50e^0.1t + 20

Using the inverse function, it is found that the equation is:

P(t) = \frac{e^{0.1t}}{50} + 20

It's initial value is 20.

---------------------------

We want to find the inverse of:

y = P^{-1}(t) = 10\ln{50t - 1000}

To do this, we <u>exchange y and t, and isolate y.</u>

Then:

10\ln{50y - 1000} = t

\ln{50y - 1000} = \frac{t}{10}

e^{\ln{50y - 1000}} = e^{0.1t}

50y - 1000 = e^{0.1t}

50y = e^{0.1t} + 1000

y = \frac{e^{0.1t} + 1000}{50}

y = \frac{e^{0.1t}}{50} + \frac{1000}{50}

P(t) = \frac{e^{0.1t}}{50} + 20

It's initial value is:

P(0) = \frac{e^{0.1(0)}}{50} + 20 = 0.02 + 20 = 20.02

Rounding, 20.

Camila wanted to create a second garden to grow even more vegetables. To determine the dimensions of her second garden, she used
OlgaM077 [116]

Using proportions, considering original measures of 10 feet, we have that:

  • The horizontal measurement of the second garden is of 7.5 feet.
  • The vertical measurement of the second garden is of 15 feet.

<h3>What is a proportion?</h3>

A proportion is a fraction of total amount.

In this problem, the total amount is the original measures of 10 feet.

The horizontal measurement has a scale factor of 75%, hence:

h = 0.75(10) = 7.5

The vertical measurement has a scale factor of 150%, hence:

h = 1.5(10) = 15
