Scrat [10]

Answer:

a) We know that atleast one or more author writes a book.

Symbol to indicate one or more is (B)

So the correct option is B

b) We know that zero to multiple books are written by any author.

Symbol to indicate zero or more is (A)

So the correct option is A

c) The fourth option is correct if we replace by many to many relationship and generate a new entity.

So the relationship betweem author and contract is one to many. So we know that there is atleast one author that represent in symbol d and books has atleast 0 that represent in symbol c.

So Fourth Option is correct d at blue side and c at red side.

d) There are two forirgn keys in table Contract one is from AuthorId and other is ISBN.

Homework 8 Matlab Write a function called fibonacciMatrix. It should have three inputs, col1, col2, and n. col1 and col2 are ver

Amiraneli [1.4K]

In this exercise we have to use the knowledge in computational language in python to write the following code:

We have the code can be found in the attached image.

So in an easier way we have that the code is:

function v = myfib(n,v)

if nargin==1

v = myfib(n-1,[0,1]);

elseif n>1

v = myfib(n-1,[v,v(end-1)+v(end)]);

end

function v = myfib(n,v)

if nargin==1

v = myfib(n-1,[0,1]);

elseif n>1

v = myfib(n-1,[v,v(end-1)+v(end)]);

elseif n<1

v = 0;

end

function [n] = abcd(x)

if (x == 1 || x==0)

n = x;

return

else

n = abcd(x-1) + abcd(x-2);

end

fibonacci = [0 1];

for i = 1:n-2

fibonacci = [fibonacci fibonacci(end)+fibonacci(end-1)];

end

>> myfib(8)

ans =

0 1 1 2 3 5 8 13

>> myfib(10)

ans =

0 1 1 2 3 5 8 13 21 34
