The ideal gas law, PV = nRT, is a well-known equation in science that describes the behavior of gases.
P is the pressure of the gas, V is the volume of the gas, n is the amount of the gas. Ris the constant, and
T is the temperature of the gas. Which of the following statements are equivalent to the equation written
above? Select all that apply.

answer: the anser is 3

step-by-step explanation:

c- 2o is equal to 9

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
