TaskA scrabble hand is a set of 7 tiles, each having one of the english uppercase letters on them, drawn uniformly at random from a bag of 100 tiles. The number of tiles of each letter are as follows: E×12, A×9, I×9, O×8, N×6, R×6, T×6, L×4, S×4, U×4, D×4, G×3, B×2, C×2, M×2, P×2, F×2,H×2, V×2, W×2, Y×2, K×1, J...

Part (a): Solving an equation and finding range of values of variablesQuestion 1 (a) Real variables x and y are related by the equation ln y – ln (y + 3) + ln 4 = 2 ln x. (i) Identify the range of values of x and y for which the expressions an either side of this equation are defined. (ii) Determine y explicitly as a function of x, that is, identify the equation in the form y = f(x). (b) By using implicit differentiation, present...

Question 1In this question you will practise working with ideals in rings that are extensions of degree 2 over the integers. It involves a number of concepts from Chapter 17. Let R be the ring Z[ √ −19 ]. (a) Let A be a subset of R defined by A = {s + t √ −19 : s,t ∈ Z, s ≡ t(mod 5)}. Show that A is an ideal in the ring R. [3] (b) The subset B = {u + v √ −19 : u, v ∈ Z, u &equiv...

MethodsTask 1: Write an essay (750-1000 words) entitled. “Computational Mathematical Software as a first-year study aid.” With reference to selected codes (all of which should be included in the appendix of your essay) reflect on what mathematical skills you have explored using software in ER1630 and how its use has improved your mathematical skills and your approach to mathematics in other modules you are studying. You should refe...
