you are givena pair (a,b) .after eatch unit of time pair(a,b)
getd changeed to (b-a,b+a).you are given the initial value of
pair and an integer n and you have to print the value of the pair at the nth unit of time

Expert Solution

here we consider the time to be starting from t=0

so at t=0 we have

at we have

now following the same pattern and making the first value as

first value = second value - first value

and second value as

second value = second value + first value

we get

at t=2 we have

now following same pattern we have at

t=3

at we have

so from this we can see that at every even position we are getting and at every odd position we are getting

here we take the base case for t=0 and t=1 to be respectively as it is given in question

so final anwer would be the following relation

ans= (a,b) if n=0

(b-a,b+a) if n =1

(n*a, n*b) if(n>0 and n is even)

( (n-1)*(b-a),(n-1)*(b+a)) (if n>1 and n is odd)

For the given pair of events A and B, complete parts (a) and(b) below. A: A marble is randomly selected from a bag containing 14 marbles consisting of 1 red, 9 blue, and 4 green marbles. The selected marble is one of the green marbles. B: A second marble is selected and it is the 1 red marble in the bag. a. Determine whether events A and B are independent or dependent. (If two events are technically dependent...

Learning Objectives After the successful completion of this learning unit, you will be able to: Implement syntactically correct C++ arrays. Solve a variety of standard problems using arrays. Array Practice I recommend that before you begin the assignment you write as many of these small ungraded programming challenges as you can. You should at least write 2 or 3 of them. They are a good way to gradually build up your confidence and skills. Of course, you'll have to write...

. Recall from the previous page that for each pair a, b with a ∈ R − {0} and b ∈ R, we have a bijection fa,b : R → R where fa,b(x) = ax + b for each x ∈ R. (b) Let F = {fa,b | a ∈ R − {0}, b ∈ R}. Prove that the set F with the operation of composition of functions is a non-abelian group. You may assume that function composition is associative
