Can someone show me how to do question 2a and all 3 and 4? I tried ratio test for 2a, but if x = 0, rhe proof doesn't work. Thanks a lot. 2. Prove the following. (a) The series o converges for all 3 € R. (b) For n e N and k € {2,..., n}, the binomial coefficient (7) satisfies *)-(-5) (-)-(---) (c) For x > 0, the sequence (1 + 5)" is monotone increasing and bounded above by...
PLEASE NOTE: PLEASE ANSWER IN MATHEMATICAL FORM!! THIS IS NOT ESSAY QUESTION. THANKS Question 5 The shortest IEEE standard for rep- expnt fraction resenting rational numbers is called half-precision float- sign (S bit) ing point. It uses a 16-bit word partitioned as in the I diagram at right. (This diagram is taken from the Wiki can be found.)

8) Given the rational function: f(x)=x6 STEP 1: Factor the numerator and denominator of (v). Find the domain STEP 2: Write 1x) in lowest terms. STEP 3. Find the x-and y-intercepts. STEP 4: Determine the vertical asymptote(s) (VA). Does f have any holes in its graph? If so, determine the x-values of the holes STEP 5: Determine the horizontal asymptote (HA) if one exists. Determine if /intersects the HA. If fdoes intersect the HA, what is the ordered pair? STEP...
1. Write R' = {(x, y) |X, Y ER} to represent the set of all 1x2 row vectors of real numbers. This is the standard Euclidean plane you all know and love. If such a row vector is multiplied on the right by a 2x2 matrix, then the output is again in R"; such matrices are called linear transformations. 1. Find a linear transformation that rotates the plane R by a radians. That is, find a matrix T such that...
PART B: Calculating Limits 1) In algebra classes you typically learn that the horizontal asymptote of a rational function (z)N() D(x) is determined by the degree of the numerator and by the degree of the denominator. That is, if the degree of N(a) is less than the degree of D(x) the horizontal asymptote is y 0 N(r) D(x) lim f(x) lim 0 If the degree of N(x) and the degree of D(x) are the same then the horizontal asymptote is...
