The population model describing the population of antelope in an area is:

The maximum population sustainable in the area is 135, and the current population is 89. Find the population of antelope after each of the first ten years. Be sure to round to the nearest whole number before each calculation.

A. 101, 110, 116, 121, 125, 128, 130, 131, 132, 133
B. 135, 135, 135, 135, 135, 135, 135, 135, 135, 135
C. 89, 101, 110, 116, 121, 125, 128, 130, 131, 132
D. 121, 135, 136, 135, 135, 135, 135, 135, 135, 135

Answer :

The correct option is c. 89, 101, 110, 116, 121, 125, 128, 130, 131, 132, 133.

To solve this problem, we will use the given population model:

[tex]\[ P_{n+1} = P_n + r(P_n)(1 - \frac{P_n}{K}) \][/tex]

We will calculate the population for each of the first ten years using the model, rounding to the nearest whole number before each calculation.

Starting with [tex]\( P_0 = 89 \)[/tex], we apply the model iteratively:

[tex]\[ P_1 = P_0 + 1.75(P_0)(1 - \frac{P_0}{135}) \][/tex]

[tex]\[ P_1 = 89 + 1.75(89)(1 - \frac{89}{135}) \][/tex]

[tex]\[ P_1 \approx 89 + 1.75(89)(1 - 0.6593) \][/tex]

[tex]\[ P_1 \approx 89 + 1.75(89)(0.3407) \][/tex]

[tex]\[ P_1 \approx 89 + 1.75(30.2293) \][/tex]

[tex]\[ P_1 \approx 89 + 52.8958 \][/tex]

[tex]\[ P_1 \approx 141.8958 \][/tex]

Since we need to round to the nearest whole number before each calculation, we take [tex]\( P_1 \approx 142 \)[/tex].

However, we notice that the population cannot exceed the carrying capacity [tex]\( K \)[/tex]. Therefore, we must adjust the population to not exceed [tex]\( K \)[/tex]. In this case, since [tex]\( P_1 \)[/tex] exceeds [tex]\( K = 135 \)[/tex], we set [tex]\( P_1 = 135 \)[/tex].

Now, for each subsequent year, we apply the same formula, ensuring that the population does not exceed [tex]\( K \)[/tex]. Here are the calculations for the first ten years:

[tex]\[ P_2 = 135 + 1.75(135)(1 - \frac{135}{135}) \][/tex]

[tex]\[ P_2 = 135 \][/tex]

[tex]\[ P_3 = 135 + 1.75(135)(1 - \frac{135}{135}) \][/tex]

[tex]\[ P_3 = 135 \][/tex]

Well formatted question is in the picture attached below.

Answer:

(89, 101, 110, 116, 121, 125, 128, 130, 131, 132)

Step-by-step explanation:

Given the function that models the population of antelopes :

Pn+1 = [1.75(Pn)^2/(Pn-1)] + 32 - Pn

n = 1

P1+1 = [1.75(Pn)^2/(Pn-1)] + 32 - Pn

Initial population, Pn = P1 = 89

P2 = (1.75(89)^2/(89-1)) + 32 - 89 = 100.519 = 101

P3 = (1.75(101)^2/(101-1)) + 32 - 101 = 109.52 = 110

P4 = (1.75(110)^2/(110-1)) + 32 - 110 = 116.27 = 116

P5 = (1.75(116)^2/(116-1)) + 32 - 116 = 120.77 = 121

P6 = (1.75(121)^2/(121-1)) + 32 - 121 = 124.51 = 125

P7 = (1.75(125)^2/(125-1)) + 32 - 125 = 127.51 = 128

P8 = (1.75(128)^2/(128-1)) + 32 - 128 = 129.76 = 130

P9 = (1.75(130)^2/(130-1)) + 32 - 130 = 131.26 = 131

P10 = (1.75(131)^2/(131-1)) + 32 - 131 = 132.01 = 132

(89, 101, 110, 116, 121, 125, 128, 130, 131, 132)
