Answer:

c) 7x² + 16x +39

Step-by-step explanation:

g(x) = 6(x + 2)² + (x - 3)(x - 5)

g(x) = 6(x² + 2*2x + 2²) + (x² - 3x - 5x + 15) =

= 6x² + 24x + 24 + x² - 8x + 15 = 7x² + 16x + 39

At the start of the recovery period, the waterbuck population contained only 140 individuals. The population had 0.67 births per
Sergio [31]

Answer:

the intrinsic growth rate of the population = 0.67 - 0.06 = 0.61 or 61%

Step-by-step explanation:

since populations increase exponentially, the same will happen here

in 5 years the population should be:

P₅ = P₀e°⁶¹ˣ⁵ = 140e°⁶¹ˣ⁵ = 2,956.15 ≈ 2,956

in 10 years the population will be:

P₁₀ = P₀e°⁶¹ˣ¹⁰ = 140e°⁶¹ˣ¹⁰ = 62,420.09 ≈ 62,420

when you are using exponential growth rates, we have to assume that r will always remain constant
