Answer:
float avg = 23.5;
Explanation:
Given
The declarative statements
Required
Determine which of them is invalid
<em>Analyzing them one after the other;</em>
int zebraCnt = 40000;
This statement is valid as zebraCnt is correctly declared as type integer
<em></em>
long birdCnt = 222_222_222_222_222L;
This statement is valid as birdCnt is correctly declared as type long
float avg = 23.5;
This statement is invalid as avg is incorrectly declared as type float.
<em>To correctly declare avg, you either change the datatype to double: as follows;</em>
double avg = 23.5;
or <em>append f to the declaration; as follows</em>
float avg = 23.5f;
double avg = 98.32121;
This statement is valid as avg is correctly declared as type double
Hence, the incorrect declarative statement is float avg = 23.5;
Answer:
Explanation:
A computer system can interact with its environment using hardware that does so such as cameras, robotic arms, thermometers, smart devices etc. These hardware devices gather information from the environment and transfer it to the computer system in a format known as bits through binary electrical impulses. If the system is designed to be autonomous then the only human interaction needed would be the initial setup of the system and its hardware, once this is done the system does not need any more human interaction as long as nothing breaks.

Answer:
16pi or 50.24
Explanation:
The area of a circle is pi(r)^2, and since r = 4, then the area is pi * 4^2 which is 16pi.
Answer:
The correct answer to this question is given below in the explanation section.
Explanation:
The labels to AS engine are given below from left to right respectively.
- Fan
- Compressor
- Combustion
- Turbine
- Mixer
- Nozzle
Fan: Drawer air into the engine
Compressor: Compressor spins the air very fast. This sequeezes or compresses the air
Combustion: Air and fuel are mixed together and ignited in the combustor and it gets super hot and gas expanded.
Turbine: The hot gases enter the turbine, causing the blade on it to spin.
Mixer: The mixer combines the hot air with outside air in the engine. This reduces the heat and noise that is coming from the engine.
Nozzle: nozzle is where the exhaust is coming out from the engine, creating thrust. It works according to newton's third law.
