The reproduction function for a sardine is f(p) = −0.0005p2 + 4p, where p and f(p) are in hundred metric tons. Find the populati

tensa zangetsu [6.8K]

Answer:

Population (p) = 4,000 hundred metric tons

Size of the yield (f(p)) = 8,000 hundred metric tons

Step-by-step explanation:

The population of sardines 'p', for which the derivate of the function f(p) is zero, is the population that gives the maximum sustainable yield:

$f(p) = -0.0005p^2 + 4p\\\frac{df(p)}{dp}=-0.0010p+4\\-0.0010p+4 =0\\p=4,000$

The size of the maximum sustainable yield is:

$f(p) = -0.0005p^2 + 4p\\f(4,000) = -0.0005(4,000^2) + 4*4,000\\f(4,000) = 8,000$

Population = 4,000 hundred metric tons

Size of the yield = 8,000 hundred metric tons

Evaluate y=x squared minus 2x plus one for 3i

pychu [463]

Answer:

$- 8 - 6i$

Step-by-step explanation:

The given expresion is

$y = {x}^{2} - 2x + 1$

We want to evaluate this expression when x=3i

We substitute to obtain:

$y = {(3i)}^{2} - 2(3i) + 1$

We simplify to get

$y = {3}^{2} \times {i}^{2} - 6i + 1$

Recall that

${i}^{2} = - 1$

This implies that:

$y = 9 \times - 1 - 6i + 1$

$y = - 9 - 6i + 1$

$y = - 8 - 6i$
