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
Explanation:
Melanin is the pigment which absorbs UV light and it is present in skin and gives black colour to it.As we can see africans usually have black skin as they have to face direct uv light.
A thorough soil analysis
Explanation:
A through soil analysis must be included in Jordan's report in order to ascertain is findings.
Since he seeks to determine the effect of various soil pH on plant growth, it is pertinent he performs a pH analysis of the soil.
- The soils pH is the independent variable. It is the cause of the varying plant growth according to the hypothesis he must have formulated,.
- The dependent variable is the pant growth.
- It will be incomplete to exclude the soil analysis report from his findings.
The soil is the component that contains the minerals that conditions pH.
