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

16. Explain why pollution caused the shift in the phenotypes of the peppered moth during the Industrial Revolution. (2pts)
andrey2020 [161]

Answer/Explanation:

Pollution during the industrial revolution caused trees to become covered with soot, making them darker. This dark appearance meant that the peppered moth, which usually had a light colour, was clearly visible against the tree. This meant it was easier for predators to identify. As a result, their numbers decreased because they were an easier target.

However, there was also a rarer form of the moth, which was dark in colour. These were initially very rare. However, because of the change in the tree colour owing to the industrial revolution, these moths were better suited to the environment, as they were more camouflaged against the dark tree. This meant it was easier for them to avoid predators, and so they were more likely to survive to reproductive age and pass on the genes that produce the dark colour.  This meant that the dark moths increased in number.
