A firm has the marginal-demand function where D(x)=-1400x÷√25-x² is the number of units sold at x dollars per unit. Find the dem
borishaifa [10]

The equation of the demand function is D(x) = 1400√(25-x²) + 11400

<h3>How to determine the demand function?</h3>

From the question, we have the following parameters that can be used in our computation:

Marginal demand function, D'(x) = -1400x÷√25-x²

Also, we have

D = 17000, when the value of x = 3

To start with, we need to integrate the marginal demand function, D'(x)

So, we have the following representation

D(x) = 1400√(25-x²) + C

Recall that

D = 17000 at x = 3

So, we have

17000 = 1400√(25-3²) + C

Evaluate

17000 = 5600 + C

Solve for C

C = 17000 - 5600

So, we have

C = 11400

Substitute C = 11400 in D(x) = 1400√(25-x²) + C

D(x) = 1400√(25-x²) + 11400

Hence, the function is D(x) = 1400√(25-x²) + 11400

Which of the binomials below is a factor of this trinomial? x^2 + 3x - 4A. x+4B. x+8C. x-4D. x^2+4
Usimov [2.4K]

Given:

The equation is:

x^2+3x-4

Find-:

Binomials factor of the equation

Explanation-:

The quadratic equation,

x^2+3x-4

Solve for factor

\begin{gathered} =x^2+3x-4 \\  \\ =x^2+4x-x-4 \\  \end{gathered}

Then the factor is:

\begin{gathered} =x^2+4x-x-4 \\  \\ =x(x+4)-1(x+4) \\  \\ =(x+4)(x-1) \end{gathered}

So, the factor is x + 4
