The revenue equation (in hundreds of millions of dollars) for barley production in a certain country is approximated by R(x)=0.0631x^2 +1.3878x +2.1447 where x is in hundreds of millions of bushels. Find the marginal-revenue equation and use it to find the marginal revenue for the production of the given number of bushels.

Marginal revenue equation is 0.1262x +1.3878 the production of the given number of bushels.

Step-by-step explanation:

Explanation:-

Given the revenue equation is R(x)=0.0631x^2 +1.3878x +2.1447

where 'x' is in hundreds of millions of bushels.

marginal revenue formula is  calculated by dividing the change in quantity sold    

Now differentiating R(x) with respective to 'x' , we get

conclusion:-

Marginal revenue equation is 0.1262x +1.3878 where 'x' the production of the given number of bushels.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
