Answer:
FFF4
Explanation:
Binary representation of 12 = 00001100
Expressing it in hexadecimal format : 0C
Binary representation of -12:
Step 1 : Computing 1's complement for 12 =11110011
Step 2 : Adding 1 to 1's complement to get the 2's complement =>
11110011+1 = 11110100
Converting the 2's complement representation to hexadecimal format:
F4 ( 8 bit representation) or FFF4 ( 16 bit representation)

Answer:
B. Incremental Build life cycle
Explanation:
RAD life cycle: RAD model of software development life cycle is all about coming up with prototype as soon as possible. It describes a method of software development which heavily emphasizes rapid prototyping and iterative delivery.
Incremental build life cycle: In incremental build model of software development life cycle, each release of the software have added capabilities. The development is finished when the user is okay with the present features. Focus is put on creating a working prototype first and adding features in the development life cycle. This is the correct option.
Waterfall life cycle: In a waterfall model, each phase must be completed fully before the next phase can begin and this usually takes time before a working software can be released. There is also no overlapping in the phases.
Spiral life cycle: Spiral Model can be pretty costly to use and doesn't work well for small projects. It's a risk-driven model which means that the overall success of a project highly depends on the risks analysis phase.
