SCHEME

  1. [2 marks] Define a procedure between? that takes 3 numbers representing a value (x) and a range (a,b) respectively . The procedure should return true if the first argument falls between the remaining two (inclusive), that is if x ∈ [a,b].
    Note: the two arguments representing the range can be in either order ([a,b] or [b,a]).
    E.g. (between? 1 2 3) → #f
    E.g. (between? 7.5 5 10) → #t
    E.g. (between? 7 10 5) → #t

Answer #1

Code:

(define (between? x a b)
(cond ((or (and (> x a) (< x b)) (and (> x b)(< x a))) #t) ;;if value is betwwen a and b OR b and a return true
(else #f))) ;;else return false

LISP [3 marks] Write a procedure called triangle that takes three numbers as arguments representing the three side-lengths of a triangle. The procedure should classify the triangle and return one of the following strings: "Equilateral" "Isoceles" "Scalene". E.g. (triangle 2 3 4) → "Scalene" E.g. (triangle 2 3 2) → "Isoceles"

Defining a Class Define the class Rectangle. It’s constructor takes a pair of numbers representing the top-left corner, and two other numbers representing the width and height. It has the following methods: get_bottom_right() - return the bottom right corner as a pair of numbers. move(p) - move the rectangle so that p becomes the top-left corner (leaving the width and height unchanged). resize(width, height) - set the width and height of the rectangle to the supplied arguments (leaving the top-left...

a) Define a function to be x^3+3x-4 and define another function to be x^2-5x+10. **Note: Use different names for each function. b) Plot both functions from part a on the same graph from x=-5 to x=5. Define a range of 0 to 100 with the PlotRange option. Use the PlotLegends option to label the functions with their "Expressions".

JAVA Problem 1: Summing It Up Write a program, which takes two distinct integers separated by space as input and prints the sum of all the integers between them, including the two given numbers. Note that the numbers can appear in either order. You may assume that both numbers are between –10, 000 and 10, 000. For example, if the input is as follows: 10 4 the output should be 49, since 10+9+8+7+6+5+4=49. Similarly, if the input is -3 10...
