Solve the equation by the Quadratic Formula. x^2+3=9x
Nadya [2.5K]

Answer:

Step-by-step explanation:

Rearrange the given x^2+3=9x in standard quadratic form:

1x^2 - 9x +3 = 0

Then the three coefficients are a = 1, b = -9 and c = 3.

The discriminant is √(b^2 - 4ac), or √(81 - [1][3]), or √78.

                                        ± √78

Thus, the roots are x = ----------------

Let​ R(x), C(x), and​ P(x) be,​ respectively, the​ revenue, cost, and​ profit, in​ dollars, from the production and sale of x it
sp2606 [1]

Answer:

P(x) = -0.004x^2 - 3.7x - 50

Step-by-step explanation:

We have to find profit P(x).

This can be easily found using a formula for Profit given the Revenue and Cost.

Profit = Revenue - Cost

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

Given that:

R(x) = 6x

C(x) = 0.004x^2 + 2.3x + 50

to find P(x) we can simply subtract R(x) by C(x).

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

P(x) = (6x) - (0.004x^2 + 2.3x + 50)

P(x) = 6x - 0.004x^2 - 2.3x - 50

and finally, after simplify this equation subtracting 6x by 2.3x.

this is the equation for the profit P(x)

P(x) = -0.004x^2 - 3.7x - 50
