If R(x) rupees is the total revenge received from the sale of x tables and ` R(x)=600x-x^3/25,` find the marginal revenue when x =25.

The total revenue in Rupees received from the sale of x units of a product is given by R(x) = 13x^(2) + 26x + 15. Find the marginal revenue when x = 7.

The total revenue in Rupees received from the sale of x units of a product is given by R(x) = 3x^(2) + 36x + 5. Find the marginal revenue, when x = 5, where by marginal revenue we mean the rate of change of total revenue with respect to the number of items sold at an instant.

The total revenue in Rupees received from the sale of x units of a product is given by R(x) = 3x^(2) + 36x + 5. The marginal revenue, when x = 15 is

The total cost C(x) in Rupees, associated with the production of x units of an item is given by C(x) = 0.005x^(3)- 0.02 x^(2)+30x+5000 Find the marginal cost when 3 units are produced, where by marginal cost we mean the instantaneous rate of change of total cost at any level of output.

The total cost C(x) in Rupees associated with the production of x units of an item is given by C(x) = 0.007x^(3) - 0.003x^(2)+15x+4000 . Find the marginal cost when 17 units are produced.

Find the derivatives w.r.t. x : x^(x)

If the marginal function for x units of output is given by (6)/((x+2)^(2))+5 , find the total revenue function and the demand law.

If R={(x,y): x,y in W, x ^(2)+y^(2)=25} , then find the domain and range of R.

Find the domain and range of each of the following relations : R_(4) ={(x,y) :x and y are integers and x^(2)+y^(2) = 25 }
