Helium gas is in a cylinder that has rigid walls. If the pressure of the gas is 3.00 atm, then the root-mean-square speed of the helium atoms is $v_{rms} = 176$ m/s. By how much (in atmospheres) must the pressure be increased to increase the $v_{rms}$ of the He atoms by 150 m/s? Ignore any change in the volume of the cylinder. A. 1.00 atm. B. 2.13 atm. C. 4.25 atm. D. 7.29 atm.

2. Multivariable Calculus (a) Given $f(x, y) = \cos xy + 3x^2e^{-y}$, Show the second partial derivatives $f_{xy} = f_{yx}$. (b) The linear approximation to a function at point (a,b) is given by $f(a,b) \approx L(x, y) = f(a,b) + f_x(a, b) (x - a) + f_y(a, b) (y - b)$. (i) Find the linear approximation of the function $f(x, y) = e^{2x^2+3y}$ at (0,0) and (ii) use it to approximate $f (0.01, -0.02)$. (c) Find and classify the critical points of: $f(x,y) = 2x^4 - 8xy + y^2 - 3$.

(8 points) For each of the following integrals, give a power or simple exponential function that if integrated on a similar infinite domain will have the same convergence or divergence behavior as the given integral, and use that to predict whether the integral converges or diverges. Note that for this problem we are not formally applying the comparison test; we are simply looking at the behavior of the integrals to build intuition. (To indicate convergence or divergence, enter one of the words converges or diverges in the appropriate answer blanks.) $\int_1^\infty \frac{x}{x+7} dx$ : a similar integrand is 1 so we predict the integral diverges $\int_1^\infty \frac{x+6}{x^4+4x^3+6} dx$ : a similar integrand is so we predict the integral converges $\int_1^\infty \frac{x^3+1}{x^4+8x+6} dx$ : a similar integrand is so we predict the integral diverges $\int_1^\infty \frac{1}{e^{3x}+6} dx$ : a similar integrand is so we predict the integral converges
