A model for a​ company's revenue from selling a software package is ​R(p)equals=−2.52^2400​p, where p is the price in dollars of
dsp73

A model for a​ company's revenue from selling a software package is ​R(p)=-2.5p² + 400​p, where p is the price in dollars of the software. What price will maximize​ revenue? Find the maximum revenue.

Answer: p = $80,  R = $16,000

Step-by-step explanation:

The maximum is the y-value of the Vertex.

Step 1: Use the Axis-Of-Symmetry (AOS) formula to find x:

x=\frac{-b}{2a}

R(p) = -2.5p² + 400

     a= -2.5  b=400

p=\frac{-(400)}{2(-2.5)}

         = \frac{-400}{-5}

        =80

∴ In order to maximize the value, the company will sell the software package for $80

Step 2: Find the maximum by plugging the p-value (above) into the given equation.

R(80) = -2.5(80)² + 400(80)

         = -16,000 + 32,000

         = 16,000

Which of the following consist of prokaryotic cells?
Ad libitum [116K]

The correct answer is D. Bacteria and archaea

Explanation:

In biology, cells can be mainly classified into prokaryotic and eukaryotic. The prokaryotic cells are cells with no nucleus or centrioles but they do have a cell wall, usually one chromosome and complex cilia and flagella. On the other hand, prokaryotic cells have a defined nucleus, multiple chromosomes, and centrioles and some have a cell wall. Due to the differences between these two type of cells they are part of different organisms, in the case of eukaryotic cells, these are part of the complex organism that includes animals, plants, and fungi while prokaryotic cells are those found in bacteria and archaea which are organisms with only one cell. Considering this, the ones that consist of prokaryotic cells are bacteria and archaea.

Assume a population of deer has a crude birth rate of 36 per 1,000/yr, a crude death rate of 20 per 1,000/yr, an immigration rat
jeka57 [31]

Answer:

0.023%

Explanation:

The Population growth rate is a change in population with time taken into consideration. It can be expressed with the formula

N/t where N is the total change in the population size, and t is time.

When immigration and emigration are factored in, we now have the formula;

(CBR +I) - (CDR + I)/1000

= (36 + 15) - (20 + 8) = 51 - 28= 23\\\\expressing as a percentage of the population gives us,\\\\23/1000=0.023%\\\\
