Symbolize the following by using qualifiers, predicates and logical connectives.
- All rational numbers are real numbers.
- some rational numbers are integers.
- some even numbers are multiplied of two four and five.
- some triangles are scalene.
- every integer is multiple of 10 if and only if it is a mulple of 5 and 2.
Write a java program that computes the area & perimeter of either a rectangle, a circle or a right-angled triangle. The program should display a menu that enables the user to select the type of figure whose area & perimeter he/she wants to compute. Depending on the users choice, the program should prompt for the dimensions and perform the computations. The output should be: - The type of figure, the dimensions, the area and the perimeter. (NB:The calculation should be for only one figure at any one time.)

Prove that every non-trivial sub group of cyclic group has finite index. Hence prove that (Q,+) is not cyclic.
A boy throws a ball of mass 0.293 - kg straight upward with an initial speed of 23m/s. When the ball returns to the boy, its speed is 18.24 m/s. How much work does air resistance do on the ball during its flight?

Solution #1 is a 0.025 M solution of hypochlorous acid, HOCl (Ka = 3.0 × 10–8). Calculate each of the
following quantities for Solution #1.
(a) [H+] in Solution #1
why is beaker ,rather than a conical flask used ,when dissolving the solute.
Salt is often used to melt ice and snow on roads in the winter and the
temperature right now is -4.500ºC. How much NaCl (complete dissociation) would be
necessary to melt 1000kg of ice by bringing down the freezing temperature to -
4.500ºC?
when the solution has been made up ,why is it necessary to mix the contents of the flask thouroughly? what feature of the volumetric flask makes this particularly necessary
