Math Problem Statement

The size of a certain insect population is given by ​P(t)equals300e Superscript . 01 t​, where t is measured in days. At what time will the population equal 1500​? Question content area bottom Part 1 It will take    enter your response here days for the population to equal 1500. ​(Round to one decimal place as​ needed.)

Solution

We are given the population equation P(t)=300e0.01tP(t) = 300e^{0.01t}, where P(t)P(t) is the population at time tt in days, and we want to find the time tt when the population reaches 1500.

We set P(t)=1500P(t) = 1500 and solve for tt.

1500=300e0.01t1500 = 300e^{0.01t}

Step 1: Divide both sides by 300

1500300=e0.01t\frac{1500}{300} = e^{0.01t} 5=e0.01t5 = e^{0.01t}

Step 2: Take the natural logarithm (ln) of both sides

ln(5)=ln(e0.01t)\ln(5) = \ln(e^{0.01t}) ln(5)=0.01t\ln(5) = 0.01t

Step 3: Solve for tt

t=ln(5)0.01t = \frac{\ln(5)}{0.01}

Now, we can compute this:

t=ln(5)0.011.60940.01=160.94t = \frac{\ln(5)}{0.01} \approx \frac{1.6094}{0.01} = 160.94

Rounding to one decimal place, t160.9t \approx 160.9 days.

Thus, it will take approximately 160.9 days for the population to reach 1500.

Would you like more details or further clarification?

Here are 5 questions that expand upon this concept:

  1. How does the population change over time when tt increases?
  2. What would the population be at t=0t = 0 days?
  3. How would you find the rate of growth of the population at any given time tt?
  4. If the growth rate constant changed to 0.02, how would that affect the time to reach 1500?
  5. How long would it take for the population to double?

Tip: Always check the base of the logarithm you use to ensure it's appropriate for the problem (e.g., natural logarithm for base ee).
