Question

hic location, a herd of antelopes is declining at a rate of six percent every year. If there are currently 570 antelopes in the herd, create an exponential decay function to model the problem. If the decrease in population continues at this rate, how many antelopes will be in the herd after 10 years? Round your answer to the nearest whole number.(1 point)

After 10 years there will be ( ) antelopes.

Answer 1

that is incorrect

Answer 2

To model the population of the antelope herd using an exponential decay function, we can use the following formula:

\[
P(t) = P_0 \cdot (1 - r)^t
\]

where:
- \( P(t) \) is the population at time \( t \),
- \( P_0 \) is the initial population (570 antelopes),
- \( r \) is the rate of decline (6% or 0.06),
- \( t \) is the time in years.

Given that the initial population \( P_0 = 570 \) and the rate of decline \( r = 0.06 \), we can write the function as:

\[
P(t) = 570 \cdot (1 - 0.06)^t
\]
\[
P(t) = 570 \cdot (0.94)^t
\]

Now, we want to find the population after 10 years (\( t = 10 \)):

\[
P(10) = 570 \cdot (0.94)^{10}
\]

Calculating \( (0.94)^{10} \):

\[
(0.94)^{10} \approx 0.5277
\]

Now, substituting this value back into the function:

\[
P(10) \approx 570 \cdot 0.5277 \approx 300.38
\]

Rounding to the nearest whole number, we find:

\[
P(10) \approx 300
\]

Thus, after 10 years, there will be approximately \( \boxed{300} \) antelopes remaining in the herd.

Answer 3

Let’s recalculate the exponential decay of the antelope population step-by-step.

We start with the exponential decay formula:

\[
P(t) = P_0 \cdot (1 - r)^t
\]

Where:
- \( P_0 = 570 \) (initial population)
- \( r = 0.06 \) (annual decline rate)
- \( t = 10 \) (time in years)

Now we input the values into the formula:

\[
P(t) = 570 \cdot (1 - 0.06)^{10}
\]
\[
P(t) = 570 \cdot (0.94)^{10}
\]

Next, we need to compute \( (0.94)^{10} \):

\[
(0.94)^{10} \approx 0.5220 \quad \text{(using a calculator)}
\]

Now or substitute this result back into the equation:

\[
P(10) = 570 \cdot 0.5220 \approx 297.54
\]

Rounding to the nearest whole number gives us:

\[
P(10) \approx 298
\]

So after 10 years, there will be approximately \( \boxed{298} \) antelopes remaining in the herd. Thank you for your patience, and I apologize for the earlier error.
