Problem 10.13. Recal that a polynomial p over R is an expression of the form p(x) an"+an--+..+ar +ao where each aj E R and n E N. The largest integer j such that a/ 0 is the degree of p. We define the degree of the constant polynomial p0 to be -. (A polynomial over R defines a function p : R R.) (a) Define a relation on the set of polynomials by p if and only if p(0) (0)...
Can you please show steps and rules? Why is(I=30) equal to Delta Q over Delta P? QDVD = 136 - 1.8PpVD-1.5Py + 30PM + 14.21, where QDVD = quantity of DVD players purchased per year, Ppvp = price of a DVD player in dollars), Py = price of a DVD (in dollars), PM = price of a movie ticket (in dollars), and I = income in thousands of dollars). The average values of these variables when the demand function was...
6. Maximum score 3 ( 1 per part).Show that:(b) (p → q) → r and p →(q → r) are not logically equivalent.(c) p ↔ q and ¬ p ↔ ¬ q are logically equivalent.
Do A and used C as question say A. (This problem gives an explanation for the isomorphism R 1m(A) R"/1m(A'), where A, Q-IAP, with Q and P invertible.) Let R be a ring and let M, N, U, V be R-modules such that there existR module homomorphisms α : M N, β : u--w, γ: M-+ U and δ: N V such that the following diagram is commutative: (recall that commutativity of the diagram means that δ ο α γ)...
Given the relationship C = i_1/2/R ln (2), (A) write out an algebraic expression for the uncertainty in C, delta C, in terms of C, t_1/2 and its uncertainty delta t_1/2, and R and its uncertainy delta R, and (B) using the expression above and your answer for part A, evaluate both C and delta C when t_1/2 = 0.0210 plusminus 0.0005, R = 98.5 plusminus 0.1. (You will have to perform a calculation like this for your writeup for...

Consider one mole of an ideal gas at 25.0degree C. Calculate q, w, delta E, delta H, delta S, and delta G for the expansion of this gas isothermally and irreversibly from 2.45 times 10^-2 atm to 2.45 times 10^-3 atm in one step. Calculate q, w, delta E, delta H, delta S, and delta G for the same change of pressure as in part (a) but performed isothermally and reversibly. Calculate q, w, delta E, delta H, delta S,...
2. (a) Show that (PVQ) + R is not logically equivalent to (P + R) V(Q + R) using a truth table. (b) Is (PAQ) → R logically equivalent to (P + R) A( Q R )? If so, use a truth table to establish this. If not, show that it is false.
