A fertilizer producer finds that it can sell its product at a price of dollars per unit when it produces units of fertilizer. Th
Vilka [71]

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

Explain why the shape of animals is basically spherical whereas plants and fungi are filamentous
Reika [66]
Plants and fungi are usually filamentous to increase the surface area in which they uptake their food, and this is advantageous as they raise their surface area for sunlight in photosynthesis.
Conversely, animals are usually round to reduce surface area for loss of water and heat. Unlike plant and fungi, most of their food intake is through the mouth hence not affected by surface area.

d) Personal activities, including work.

c) Education.

f) Social recreation issues.

g) Environmental conditions (current and future conditions).

a) Material life

h) Financial safety and security.

Explanation:

The quality of life is an index that is calculated by using different estimators that covers diverse aspects of human life such as, among others health, safety, happiness, security, transportation, etc. The INEGI (National Institute of Statistics and Geography, Mexico) calculates the quality of life by using the estimators above described (and others). In my opinion, the most important one of this list is political governance, because it is an underlying characteristic that has a direct effect on the further estimators, thereby affecting their performance in a short/medium-term period.
