can you please answer all parts to the questions (JAVA code please )

and can you as well send screenshots of the code you did from Eclipse or whatever you use. Its more understandable than just writing it on here.

thank you!

(2/3+4/9) - (5/11 - 4/3) c. 1+1 = (2+1+(1 + 1/2)) d. 1 -2 X 3 X 4 X 5 X-6 x 7 Exercise 2 Draw how the expression / (+54) (-8 (23))) is executed using a stack based architecture. Exercise 2 Draw how the expression (/ (+54) (-8(*2 3))) is executed using a stack based architecture. Exercise 3 Writing Functions: 1. Write a function, c->f, that will convert celsius to fahrenheit. F = 19/5) * C + 32. 2. Write 3 functions, discrim, quad+, and quad-. Each function will have 3 parameters: a, b and c -b+Vb2-4ac that represent the coefficients of a quadratic equation X = discrim will be the 2a the part of the formula: b-4ac. Both quad+ and quad- will use the discrim function. 3. Write a function solutions, with 3 parameters: a, b and c that represent the coefficients of a quadratic equation. Evaluate the discriminant, b-4ac, and return a string the appropriate stating: Discriminant - 0 String "two imaginary solutions" "one real solution" "two real solutions" 4. Write a function, quadrant, with 2 parameters: Xandy that represent coordinates of a point in a Cartesian coordinate system (x,y). Determine which quadrant the point is located in and return one of the following: 1, II, III, IV, x-axis, y-axis or origin b-4ac0 b -4ac > 0 one real solution "two real solutions" 4. Write a function, quadrant, with 2 parameters: x and y that represent coordinates of a point in a Cartesian coordinate system (x,y). Determine which quadrant the point is located in and return one of the following: 1, II, III, IV, x-axis, y-axis or origin. Submit on Canvas, a Scheme or Racket source file with Exercise 3 functions.
