1. Set up the double integral in polar coordinates that calculates the volume of the given solid. Do not evaluate the integral.
Below the paraboloid z = 8 - 2x2 - 2y2 and above the xy-plane.
2. A lamina occupies the part of the disk x2 + y2 49 in the first quadrant. Set up the integrals that calculate the center of mass of the lamina if the density at any point is proportional to the square of its distance from the origin. Do not evaluate the integrals.
Find the first five terms in the Taylor series about x = 0 for f(x). Find the interval of convergence for the series in part (a).
Suppose that for X = net amount won or lost in a lottery game, the expected value is E(X) = -$0.50. What is the correct interpretation of this value?

Let ? be a set, and G a subgroup of the group Sym(?) of permutations of ?. Let ω ∈ ?, and let G_ω denote the stabilizer of ω in G.(a) If H is a subgroup of G such that H acts transitively on ?, show that G = HG_ω.(b) If G acts transitively on ?, show..
Step by step process in solving the following question. Using matrix algebra techniques, find a general solution of the system:
A geometric progression has first term log_2 27 and common ratio log_2 y, find the set of values of y for which the geometric progression has a sum to infinity.
If the water level is rising at a rate of 20 cm/min when the height of the water is 2 m, find the rate at which water is being pumped into the tank.
3. A 7-in. pizza costs $8 and a 14-in. pizza costs $20. Tommy says the smaller pizza is a better buy because the larger pizza is twice as big and more than twice as expensive. Do you agree with his reasoning? If not, explain why not.
