Answer:

p = 48

Step-by-step explanation:

If p is inversely proportional to the square of q

This is written Mathematically as:

p ∝ 1/q²

p = k × 1/q²

p = k/q²

Cross Multiply

k = pq²

k = Constant of Proportionality

Step 1

We find k

When p is 3 when q was 12

k = pq²

k = 3 × 12²

k = 432

Step 3

determine p when q is equal to 3

p = k/q²

p = 432/3²

p = 48

Crank

Answer:If you would like to know what will the approximate population be after 3 years, you can calculate this using the following steps:

an initial population ... 298 quail

an annual rate ... 8%

an exponential function to model the quail population:

f = 298(1+8%)^t = 298(1+8/100)^t

f ... quail population

t ... time (years)

t = 3 years

f = 298(1+8/100)^t = 298(1.08)^3 = 375.4 quail

375.4 quail after 3 years.
