WebA better solution is to keep x2= x3= 0 and to set x1= 2; we then obtain z = 10 (and x4= 1,x5= 3,x6= 2). However, if we keep x2= x3= 0 and if we set x1= 3, then z = 15 and x4= x5= x6= −1, breaking the constraint xi≥ 0 for all i. The conclusionisthatonecannotincreasex1asmuchasonewants.

WebComplex number. A complex number can be visually represented as a pair of numbers (a, b) forming a vector on a diagram called an Argand diagram, representing the complex plane. Re is the real axis, Im is the imaginary axis, and i is the "imaginary unit", that satisfies i2 = −1. In mathematics, a complex number is an element of a number system ... WebIn base 2, the base for a lot of computing - binary, you have available the digits 0 and 1. So to express the value of “two”, you would write 10, one “two” and nothing else. To write the value of “five” in base 2 you would write 101 (one 2X2=4, no “2” and one 1). The number 10 in base two would be (2X2X2 = 8) + 2 = 10 Continue Reading Alan Bustany Webin the following question which is Which of the following expressions are equivalent to I2 (AB) Option AB and (AB) I2 were correct i get why AB is correct, however, i m a bit … cheap insulin
