Determine whether the following careers would require training or college.

For positive constants a and b, the force between two atoms in a molecule is given f(r) = −a r2 + b r3 , where r > 0 is the distance between the atoms. note: a and b are upper case letters. (a) find f '(r) = (b) find the critical point for f(r). r = (c) find f ''(r) = (d) find the value of r so that f ''(r) = 0.

Your program should prompt the user for the dimensions of the two squares matrices, making sure that the user input is greater than or equal to 4.[ yes, an example would be a4x4matrix]2.if the above is not met, prompt the user for a new value.3.now generate random integernumbers to fill both matrices.4.display these two matrices on the screen.5.multiply the two matrices and display the result on the scre
