<h3><u>Answer;</u></h3>

= 3,391 viruses

<h3><u>Explanation;</u></h3>
  • The population density is 1.2 viruses per square millimeter.
  • This means, each square millimeter is occupied by a population of 1.2 viruses.

Therefore; for an area of 2,826 square millimeters, there will be;

  = 2,826 multiplied by 1.2 viruses

 = 2,826 × 1.2

 = 3391.2 viruses,

and since we can have a fraction or decimal virus then the population would be <u>3391 viruses</u>

Answer: There are 3391.2 viruses in petri dish A.

Step-by-step explanation:

Given statements : The population density is 1.2 viruses per square millimeter.

each square millimeter is representing  population of 1.2 viruses.

There is a directly proportional relation between the area and the population  .

Let x be the population of virus in perti dish A.

Therefore,

x=1.2\times2826=3391.2\ vruses

Hence, there are 3391.2 viruses in petri dish A.

Suppose you are the manager of a firm. The accounting department has provided cost​ estimates, and the sales department sales​ e
Katarina [22]

Answer:

<em>If more than 134 articles are produced and sold, the firm will have positive profits and shoule start production</em>

Step-by-step explanation:

Cost, Revenue, and Profit Function

The cost function C(x) is given by

C(x)=75x+3,350

where x is the number of produced products.

The revenue function is

R(x)=100x

With both equations, we can know the profit function as

P(x)=R(x)-C(x)

P(x)=100x-75x-3,350=25x-3,350

P(x)=25x-3,350

For the firm to have positive profits, it has to produce x articles with the condition

P(x)>0

Or, equivalently

P(x)=25x-3,350>0

Solving for x

\displaystyle x>\frac{3,350}{25}

Thus

x>134

This means that if more than 134 articles are produced and sold, the firm will have positive profits and shoule start production
