Tаble 1: DDL creаte tаble R (cоl_a char primary key, cоl_b char ); create table S (cоl_c char primary key, col_d char, foreign key (col_d) references R(col_a) ); insert into R values ('a', 'd'), ('b', 'e'), ('c', 'f'); insert into S values ('p', 'a'), ('q', 'b'), ('r', 'c'), ('s', 'a'), ('t', 'b'); Based on Table 1: DDL, Show the result of each SQL query below. Use a table or put each row on a separate line with fields separated by tabs so that the columns line up. Clearly separate answers. select R.A, T.C from R, T where R.A = T.B order by R.A, T.C; select distinct R.A, T.C from R, T where R.A = T.B order by R.A, T.C; select R.A, COUNT(T.C) AS C_COUNT from R, T where R.A = T.B group by R.A;

Write оut the аnswers tо the fоllowing. You must show аll work for credit. Correct аnswers with no work will not receive any credit. Each problem is 6 points. Scan you work and submit when done.1) Find the closed formula for the Lucas numbers. Lucas numbers have the same recurrence relation as the Fibonacci sequence, only they start with the numbers 2 and 1. Thus 2, 1, 3, 4, 7, 11, ...2) Prove by induction Prove by induction for every positive integer n, 7 + 14 + 21 + 28 + . . . + 7 n = 7 n ( n + 1 ) 2 3) Give an algebraic proof for the identity nk = n-1k-1 + n-1k 4) Write out the first five terms of a n = 5 a n - 1 + 6 a n - 2 then find a closed formula for the sequence.5) How many solutions to the equation a + b + c + d + e + f = 35 are there where no variable can be greater than 9 .6) Prove that the only Platonic solid with squares is the cube.7) Prove n is even if and only if n 2 - 1 is odd.8) Choose ONE of the following to answer:a. Describe the Mandelbrot set by discussing the difference in the points in the 'inside' points, points close to the boarder, and points further out from the boarder. Write a brief algorithm of how you would code a program like the one in the video 'whats so special about the Mandelbrot Set' in week 4 topic introduction.b. Construct a variation of the Recaman sequence numerically and also with a picture and formula. This variation is that you do not increase by one, but by even numbers. Thus move up or back 2, then 4, then 6, etc. c. It is expected in traditional mathematics that when you input data into a well -defined equation you get an expected output. We looked at the logistic equation f(x) = rx(1-x) with different initial inputs. Explain how with some initial conditions we get a predictable result but with others the result was surprisingly different – how was it different?
