Answer:

By the numbers, humans produce a lot of food—enough to provide every person on Earth 2,750 calories per day, exceeding almost all dietary recommendations.

There’s one glaring problem, however: Humans aren’t producing enough of the right food.

When researchers at the University of Guelph in Canada broke those calories down into different food groups, they found a shortage in production of the most important foods. In the long run, with the global population expected to balloon to about 10 billion people by mid-century, this could cause some serious problems.

Answer:

700

Explanation:

If from the question the price per unit of fertilizer, p(x) = 300 - 0.1x

The cost of x units of fertilizer = C(x) = 15000 + 125x + 0.025x^2

And we know that Profit = Revenue - Cost

Revenue for x units of fertilizer R(X) = x*p(x)

= 300x - 0.1x^2

Hence Profit: P(x) = R(x) - C(x)

= [300x - 0.1x^2] - [15000 + 125x + 0.025x^2]

= -0.125x^2 + 175x - 15000

To determine critical values

P'(x) = -0.25x + 175 = 0

Thus x = 175/0.25

x = 700

To maximize profit, the manufactures must produce 700 units of fertilizers

Katyanochek1 [597]

The answer would be hypothalamus.

Hypothalamus is a part of the brain that located below the thalamus (hypo mean "under"). Hypothalamus can control nervous and endocrine system. It was divided into front/anterior, tuberal and back/posterior part. Thirst would be regulated by anterior and posterior part, temperature by anterior part and sexual behaviour by anterior part.
